Why you need fast turn PCB manufacturing services
When you have to satisfy requiring target dates and also pushing routines, fast turn PCB prototyping solutions are the very best options. Quick transform motherboard make sure that you have the ability to stay up to date with the following brand-new pattern out there, as well as do not drag the competitors. Merely mentioned, you […]
An overview of the printed circuit board
A Summary of the Printed Circuit Board( PCB) Manufacturing In 1936, the initial Printed Circuit Board (PCB) was produced by Paul Eisle. Yet it had not been till the 1950s when the United States Defense sector started incorporating PCBs in their bomb detonator systems that published motherboard located broad application. PCBs are currently utilized in […]
Summary of 10 defects of PCB design process
First, the process hierarchy is not clearly defined Single-layer board is designed in TOP layer.If there is no explain, and do the design on both sides,the board made out is mounted with device,but it is bad welding. Second, a large area of the copper foil is too close from the frame . A large area […]
Practical skills summary of high frequency PCB design
PCB design goal is smaller, faster and lower cost. And because the point of interconnection on the circuit chain is the weakest link, in RF pcb design, electromagnetic properties at the point of interconnection is the main problem faced by the engineering design, to examine each of the points of interconnection and to solve existing […]
8 need-to-know Errors of PCB design
We often find some rules or principles that we take for granted will be some errors. Electronic engineers in pcb design will have such examples. The following eight errors are a summary of an engineer. Error 1: requirement of PCB board design is not high,so use a little fine line, and do the routing automatically. Comments: […]
Refuse rework! 5 golden rules of PCB design
PCB circuit board is the basal electronic components in all electronic products. As the main support, it is equipped with all the devices composed the circuit. PCB role not only combines scattered element, but also ensure the rules of the circuit design,which is good to avoid the confusion and error artificial phenomenon caused by manual […]
3W principle of PCB design
In the PCB design ,in order to reduce crosstalk between lines, we should ensure line spacing is large enough.When the distance between the line center is not less than three times than line width,you can keep most of the electric field noninterference,which is 3W principles. As shown below: meeting 3W principle enables crosstalk between signals […]
Shielding method of high-speed PCB design
Transfer rate of high-speed PCB design wiring system is steadily accelerating, it also brings a certain anti-interference vulnerability.This is because the higher the frequency of the transmission, sensitivity to signals increase, while their energy is increasingly weak. At this point wiring system is more susceptible to interference. Interference is everywhere.Cables and equipment will cause the […]
The introduction of special board plating methods in PCB manufacturing
This paper mainly describes four special plating method of the circuit board manufacturing The first kind, refers to the row type electroplating. It often requires rare metals plated on edge-board connector, edge-board protruding contacts or gold finger,in order to provide low contact resistance and high wear resistance.This technology is called row type plating or projection […]
