Flexible PCB Used in High Speed Chip To Chip Interconnection

Posted by iFast PCB on July 14, 2016 in Flex PCB

High speed chip to chip interconnection is a fairly new application for flexible circuits that has actually been produced by a convergence of conditions. As an example, it has been kept in mind with enhancing frequency by digital industry specialists that electrical and also electronic devices affiliations are the key limiters of digital efficiency. The electronic devices industry has not been blind to this truth, however it has been sluggish to react in a cohesive as well as participating manner, possibly because the electronic devices sector is no longer the monolithic market it when was. Digital design and manufacturing are self-controls that have actually attracted more apart since the process of eliminating up and down incorporated electronic devices OEM manufacturers began in the late 1980s. In earlier times, in vertically integrated OEMs, the developer was generally the manufacturer as well. With the corporate outsourcing of practically everything however advertising and also business governance, the OEMs of today are a lot a lot more hollow entities. As a result, they are typically a lot less mindful to the effects of the diffusion of design and also manufacturing processes and therefore have little opportunity to discover as well as grow en masse to meet advancing difficulties.

There has been much conversation concerning bridging the waters in between the island of design as well as the different islands of manufacturing interconnection frameworks, but it is verifying to be a challenging activity. Currently, each component of the digital inter- link pecking order is conceived as well as established with little expectancy of the influence of choices on what is to come next in the process. It has actually been pretty much a case of, “I have resolved my issue. It’s your problem currently.” The semiconductor is created with little issue for the plan and also the bundle is made with little issue for the PCB. An arguably much better strategy is to carry out concurrent design and engineering. An instance of just how a semiconductor chip and bundle might be better incorporated in terms of design and manufacture will aid to highlight the property.

Semiconductor design of today is a far cry from former times. In earlier years, a specific developer or design group would go about making the chip entirely, including all the gates required to meet the item need. Over time, the process has actually been streamlined. Presently, IP blocks of transistors with different features are made by completely various teams. These are accumulated and also integrated into a chip design with the standard tasks of affiliation as well as I/O project.

As the industry relocates to ever greater speeds, due mostly to chip feature size reduction, there will be a greater need for cooperation between silicon design as well as package design. In fact, the package can actually help to significantly improve silicon performance if the two are co-designed. The solution resides in the information channel.

When the data or signal network is tidy as well as free of electrical/electronic interruptions, it is feasible for the signal to propagate at quite high prices. This is since signal rise time and also side are not deteriorated by the typically made use of materials that place a drag out the signal as a result of their high dielectric continuous and/or high loss tangent. Moreover, a well-designed and also tidy channel need to not be subject to regular circuit path twists and turns, noise, crosstalk and the congested transmission environment of a standard PCB.
One method to achieve a well-designed, clean network is to divide the broadband signals and also treat them as having special needs. By doing so, the high speed signals can be lifted up and out of the congested on board signal website traffic and rapidly shuttled to their destinations. It is, by way of example, the application of civil engineering practices to digital design obstacles with flexible circuits playing a pivotal role.

An example of a civil technician’s method to resolving the problem in an application compared with a standard design approach can be seen in figure 3-22. This elevated very high- way technique to signal routing has some one-of-a-kind advantages and also the efficiency advantages have actually been proven in real examinations.

Flex PCB IN MEDICAL PRODUCTS

Posted by iFast PCB on July 13, 2016 in Flex PCB, PCB News

While flex PCB have found their means into matter- less products, perhaps one of the most gratifying has actually been their usage in clinical products where they have actually offered life-altering

benefits to people struggling with a range of medical problems. At the time of this composing the medical items market was reported to be $400 billion with around 28% living in the US, making technologies in the sector of clinical products extremely eye-catching as the clinical sector moves toward more personalized and also individualized medication. Currently there are 8,000 clinical product OEMs in North America. flex PCB use in clinical applications could be damaged down into 2 broad areas:

  • Flex PCB used as a way of affiliation for the packing as well as interconnection of an electronic assembly (e.g., portable monitors, implantable devices such as pacemakers).
  • Flex PCB interfacing with the individual to provide diagnostics, treatment or both.

LISTENING DEVICES.

It is interesting to note that the hearing aid was one of the first medical applications for the vacuum tube amplifier, later on one of the very first for the transistor and also ultimately the first for IC. Suppliers presented their initial transistorized behind-the- ear instruments in the early 1950s. These were extremely large by today’s standards and battery life was not very long. In contrast, listening to helps of today fit virtually indistinctly into the user’s ear. In a wonderful numerous situations listening to help modern technology miniaturization has been helped by the usage of flex PCB innovation which enables the circuit to be compactly folded after assembly. Listening devices are now so little they could suit the ear canal, supplying miniaturized wonders that return the present of audio to the customer.

ULTRASOUND TRANSDUCER HEADS.

Medical analysis devices regularly uses flex PCB technology to achieve preferred outcomes. A selection of arrangements have actually been created for many years to accomplish phenomenal image clarity that is necessary to analysis as well as treatment applications.

One effective application has been the affiliation of ultrasonic transducer moving towards ultrasound imaging where the flex PCB is utilized to both send and also get signals from a piezo ceramic to create a digital picture based upon mirrored noise. Ultrasound technology gives an one-of-a-kind, non-invasive appearance inside the body. It is most generally related to obstetricians as well as pregnant parents getting a very early check out an unborn child, but ultrasound has several other vital usages in medication where the imaging technology is really made use of inside the body. One example is an expandable ultrasound transducer array from Siemens Medical Solutions. The device is a foldable transducer array that is tiny sufficient to be inserted right into a person where it could that be unravelled for use inside the client’s body, providing a larger radiating and also analysis surface. This advance supplies medical professionals with one more method to find condition for therapy, with any luck capturing it at an earlier stage. An additional instance is intravenous ultrasound (IVUS) which allows vascular specialists to consider blockages from inside a blood vessel.

The usecases for rigid flex PCB

Posted by iFast PCB on July 12, 2016 in PCB Design, PCB News

When to choose rigid flex PCB

It’s getting harder to fit everything in the box; it’s also getting more costly. One solution promising to help designers meet the size constraint head on is rigid flex PCB technology, but most design teams try to avoid using rigid flex PCBs when product cost is an issue. Is it really as expensive as we think?
To begin with, consider the cost of the traditional rigid-cable-rigid PCB assembly to one based on rigid-flex technology. The former construction works well for short-run designs; however, it requires connectors on each board and the interconect, all of which drive up BoM cost Additionally, the rigid-cable-rigid design is prone to ‘cold joints’, and reduced service life. In contrast, rigid-flex circuits eliminate these joints, making them much more able and reliable to deliver overall higher product quality and longevity. While rigid flex PCB technology is certainly not new, various considerations now make it much more viable– not the least of which is cost.

Simulate the cost.

In some designs, rigid flex will not be a viable alternative, and you must do your due diligence in determining the break-even point where the costs are about equal. This kind of price simulation can be done by considering the total quoted costs for fabrication and assembly. The PCBs can be quoted before design, as long as the parameters of design are well understood (for example, the layer stack, estimated via count, track and space ratios, etc.).
We performed a manufacturing cost simulation with a real rigid flex design and a comparative rigid-cable-rigid equivalent. The component BoMs for comparison differed only in the cable and connectors required for the non-flex version. For our simulation, the traditional design is comprised of four-layer boards that use flexible cable and connectors between them, while the rigid-flex design is a four-layer PCB with two inner flex layers. Manufacturing cost for both designs is based on real PCB fabricator quotes, and includes the cost of assembly.

Find your break-even point

As the project volume depicted in Figure 1 hits 100 units, the rigid-flex design becomes a more cost-effective option compared to the traditional design approach. A key reason for this cost savings is that rigid-flex circuits do not use connectors/cables or require any connector assembly. They feature increased reliability and process yields. That’s just the tip of the iceberg.
Because rigid flex PCBs require no cable assembly, their overall assembly effort is reduced, as is their test complexity– both of which drive down cost. Additionally, fewer components need to be purchased, reducing the supply chain risk. Rigid flex PCBs can be designed to make product maintenance more convenient and therefore, more cost-effective over the course of the product lifecycle.

What about design time?

While the cost of manufacturing, assembly, testing, and logistics are key factors in considering the viability of rigid flex PCB technology for any given design, project and development costs can not be overlooked. Rigid flex PCB design often requires the mechanical team to assist with the flex portion of the design, and PCB integration with the final product. The process is very time costly and consuming, as well as prone to errors.
Making matters worse, PCB design tools often ignore the fitting and folding aspects of rigid flex design. Rigid flex technology design requires designers to work and think in 3D. The flex portions can be folded, twisted and rolled to follow the design of the mechanism. But traditional PCB design tools don’t support 3D board design or the definition and simulation of bends and folds in the flex portion of the design. They don’t even support the definition of different layer stacks in different parts of the design, including the areas comprising the design’s flex part.
Because of this, rigid flex designers have been forced to manually translate both the rigid and flex sections of their 3D design into a flat, 2D representation suitable for fabrication. They have to manually document all areas of the design that are flex, and double check that no vias or components have been placed near the transitions between the design’s rigid and flex portions. This process is governed by many additional rules, most of which are, not too surprisingly, not supported by most PCB design software.
In general, the extra effort it has taken to design rigid flex PCB as compared to standard rigid PCBs using traditional PCB design software has made them much less cost competitive. Luckily, modern design tools with advanced 3D capabilities, and support for the definition and simulation of bends and folds in the flex portion of the design, as well as the definition of different layer stacks in different parts of the design, are now available. These tools generally eliminate the need to handle the flex part of the design with mechanical CAD tools, saving designers and design teams both time and money.

Design in 3D to ensure success

Early coordination between the developers and the circuit board producer, supported by the use of a modern PCB design tool, is another factor making rigid-flex technology a more cost-effective option. Rigid-flex designs require closer collaboration between the designer and fabricator than traditional rigid board designs. The tradeoffs required to produce a successful rigid-flex design translate to a set of design rules the designer can develop with the fabricator’s input. These considerations include the number of layers in the design, materials selections, recommended sizes for vias and traces, adhesion methods, and dimensional control. With the right design tool, these considerations can be clearly defined and given the proper weight they deserve early on so that the rigid flex PCB can be properly optimized, further optimizing its overall cost.

There’s no denying that existing industry trends and consumer demands are pushing designers and design teams to their limits, forcing them to seek new alternatives to the electronic design challenges they now face. These challenges, and especially the requirements being placed on today’s mobile devices, are pushing rigid-flex technology into the mainstream, and making it much more commercially viable for a range of applications. The availability of modern PCB design tools that support 3D product development, early collaboration, and all necessary rigid flex definitions and simulation greatly minimize the pain of rigid flex PCB design and make it an even more compelling solution– one that under the right circumstances is cheaper than rigid-cable-rigid PCB design. For today’s design teams, that choice may just mean the difference between product success or failure.

The Introduction To The Flex PCB Market

Posted by iFast PCB on July 10, 2016 in Flex PCB

While the development and spreading of flex circuit technology was at first slow in the very early days, of the technology, it has gotten on a stable and accelerating growth path since. Today, flexible circuits, likewise known as flexible printed wiring, flex print and flex PCB, are used in almost every type of electronic as well as electrical item. A great deal of credit history is because of Japanese electronics packaging developers that have located numerous brand-new ways to use flex circuit technology in every imaginable kind of item because they started to use the innovation in the 1970s. Today, flexible circuits represent a multi-billion dollar sector, with Japan, because of its continuing application leadership, appreciating a significant and also prominent market share. The United States, when a close 2nd, has fallen behind in market share as production remains to change to China as well as other areas in Asia as well as South Asia. Still, the United States stays a high modern technology leader in areas such as stiff flex and high frequency applications.

While the development of the flexible circuit sector, in volume and also bucks, from its infancy to today has actually gone over, it has not been without issues. Failures have been experienced and tape-recorded by a substantial number of flexible circuit customers throughout the sector’s history. A lot of those that have actually been troubled by failure went into the flex circuit field without being totally prepared. New sector individuals, manufacturers as well as participants commonly lacked the encounter and knowledge had to avoid the issues they experienced. Mistakes were unfortunately repeated
by others till the lessons discovered became available to a wider base of participants and also were codified and also formalized in the standards, requirements and also design standards we utilize today.

Over the last a number of years, flexible circuits have continued to be one of the fastest expanding affiliation item market sections and also according to a current report by Prismark Partners the flex market is forecasted to expand from regarding $8 billion in worldwide profits today to over $12 billion in international annual sales by 2015. As their report points out, this stands for an impres- sive 9% annual growth price projection. In regards to production quantity amongst countries joining the flex circuit mar-.
ket, Japan has a reported 50% market share for flexible circuits.
Korea adheres to at 24%, with Taiwan/China at 16%, the United States at 9% and Europe at 2%. Prismark even more prepares for that China will certainly control 25% of market by 2015 as enhancing varieties of OEMs change manufacturing to China.

SUMMARY.
Flexible circuits have a rich background and also are exceptionally di- verse, which opens them to make use of in a wide variety of applications with new applications growing on a regular basis. It is tough to predict where the modern technology will certainly go next. Roll-to-roll handling is most likely to play a fundamental part. Currently, the US government, via the Defense Advanced Research Projects Agency (DARPA), is funding a number of projects focused on depositing transistors directly into flexible substrates in a web. This type of processing is currently called printed electronic devices by a growing number of online marketers in the market as well as there has actually been an initiative to call flexible circuits board, which can be perplexing to brand-new individuals in the market. Since flexible circuits have a nearly 100-year running start, it appears not likely that the name will certainly be changed. That said, the principle of printed electronic devices in roll-to-roll fashion is attractive as well as is confirming well-suited to huge screens. As roll-to-roll modern technology grows and also PCB manufacturing capabilities increase, it ought to open doors to a brand-new generation of flex PCB manufacturing.

How are printed circuit boards manufactured

Posted by iFast PCB on July 8, 2016 in PCB Manufacturing, PCB News

Exactly how Are Printed Circuit Boards Made?

These boards are developed by mass PCB manufacturing. These boards could likewise be made by hand making use of soldering and also etching.

When it concerns the Printed Circuit Boards that are standardized by big PCB manufacturers, high quality could commonly be a concern. Consequently, those that are seeking boards that have the format and also design that they are seeking could obtain a smaller sized business to supplier the boards for them to ensure that they are developed for their very own requirements.

Rather of merely having a mass created boards, business today could obtain their digital tools from a producer that will certainly produce a particularly made board. Business that are looking for smaller sized amounts of Printed Circuit Boards could utilize a firm that will certainly be able to give them not just with a much more hands on technique when it comes to developing the boards, however will certainly likewise be able to provide them the amounts that they are looking for.

Printed Circuit Boards, additionally referred to as PCBs are made from a mix of channel products along with non-conduit products. The objective of the boards is to place digital elements in order for them to operate for a selection of various objectives. The PCBs are usually created by makers that develop them from slim layers of copper as well as cover them with an eco-friendly epoxy based product.

Having a business construct certain published circuit boards for your business is the following ideal point to developing your very own hand made board, without having to sustain the time as well as expenditure that it would certainly take to develop such a task. Making use of a business that especially creates published circuit boards for customers could provide customers a possibility to obtain high quality design, format as well as feature that they could not or else obtain by buying mass created published circuit boards.

Flex and also Rigid Flex PCB Design Principles

Posted by iFast PCB on July 6, 2016 in PCB Design, PCB News

Flex and also Rigid Flex PCB Design Principles

The developer is typically under pressure to release the paperwork and also obtain the versatile circuit right into manufacturing. There is, however, a great deal in jeopardy. Establishing for medium-to-high quantity PCB manufacturing requires substantial physical and also monetary resources. To prevent potential warm from administration, the designer should insist on PCB prototyping the product as well as a thorough style review prior to release.

DFM Review Criteria

Comprehensive paperwork is vital. The intent is to supply the producer with a breakdown and description of the materials specified for the flex PCB circuit construction, materials stack-up, reinforced/stiffened areas, essential density locations, and also to define a solder-compatible surface coating for all component land pattern features. For the a lot more intricate multilayer and Rigid Flex PCBapplications include cross-sectional views. Crucial bend or distance places should be identified with referral dimensions and also it will be handy to equip different views showing an installed flex arrangement.

The primary referrals for assessing the Flex PCB are tooling holes as well as fiducial targets. Non-plated tooling holes are typically utilized for preserving the position of the circuit during singulation and, when backed with or part of a stiff area, PCB assembly processing. Fiducial attributes ought to be equipped in each circuit section or localized discontinuation location to provide an unvarying ‘information’ referral for a lot more specific component positioning. The optimal fiducial is a solid loaded 0.25 to 0.5 mm (.010″ to.020″) diameter circle. Cover layer material should provide sufficient clearance to make certain that it does not overlap into the fiducial target features during the cover layer-to-base circuit lamination experience.

Using fiducial functions is a common method for:
– Solder pattern x, y and also theta placement
– Precise surface install element placement
– Reducing the impacts of variable product shrinkage conditions
– Compensation for any kind of random distortions in flex PCB materials

PCB Assembly paperwork will include an expense of product, authorized supplier listing, component recommendation designators as well as any type of special requirements. Create clear, in-depth illustrations and also PCB Assembly directions. This file should include part describes and also basic places. The CAD data will provide exact part X-Y collaborates and also orientation information needed for assembly handling. All SMT tools are lined up and put into their corresponding land patterns utilizing the body facility as a reference factor for positioning collaborates. The fiducial targets explained above will certainly assist in establishing these exact X-Y collaborates for solder printing, part positioning and orientation. With flexibility comes integral dimensional instability relative to hardboards or solid steel objects. When numerous part mounting websites are separated by extreme distance it is suggested that multiple fiducial functions be provided. Using numerous information functions is an usual strategy for decreasing or removing the results of variable shrinkage or experience distortion in flex PCB materials. Several areas will certainly offer a tighter resistance within each information area or termination area while loosening up the need to maintain a tight resistance of the Flex PCBinterface between various other discontinuation locations.

Nesting and also Palletizing

Flex PCB units can be provided in panelized layouts. This style will enhance the PCB manufacturing and also assembly process effectiveness and maximizing product use. Automated handling for in-line assembly handling for Flex PCB equipped with a provisional stiff support and multilayer Rigid Flex PCB calls for a rather consistent board outline.
