There are a variety of various techniques readily available for singulating (removing as well as cutting) specific flex PCB from a refined panel, and all of these techniques apply to all kinds of flex PCB. The methods for singulating flex PCB can be branched along 2 main strategies. The first is vibrant vector-based cutting approaches, […]

The following area of interest is in the stack-up of flex PCB products made use of in the lamination procedure. Many different products have been utilized in the lamination process over the years. As a whole, these have actually been included the following: – Thermal lagging material to regulate or regulate the price of temperature […]

Coverlayers and covercoats are important topics as well as, because of their many ranges as well as facets, demanding of additional discussion. Flexible circuits usually call for a coating of some style over the finished circuits. At the same time, openings are nearly constantly needed to supply access to flex PCB features for interconnection to […]

While the foregoing discussion has given detail on the many variations of flex PCB circuit constructions it would certainly be remiss not to dedicate some discussion to the imaging and also etching procedures that are the heart of the flex PCB manufacturing process. There are a few bottom lines that should be attended to relative […]

POLYMER THICK FILM TECHNOLOGY The field of additively refined flexible circuits has been controlled by polymer thick movie (PTF) innovation. PTF has actually remained in use for a long period of time in calculator keyboards, screens and so forth, however current advances in polymer ink technology have led to rises in conductivity that make PTF […]

LASER ABLATION Lasers of basically every kind can skiving polyimide product. CARBON DIOXIDE, YAG and also excimer lasers have all been made use of to accessibility metal functions with the cover film or coverlayer by ablation. Excimer lasers are slower compared to the others, much less effective and need even more maintenance, however they could […]

BACK BARED FLEXIBLE CIRCUITS Back exposed, likewise called double side access, dual access or rear end gain access to, flexible circuits are most generally solitary conductor layer circuits that have their metal conductors accessed or accessible from both sides. The back access technique is typically used when part soldering or one more interconnection approach is […]

SEMI-SUBTRACTIVE PROCESSING While there are no set interpretations for semi-subtractive processing, the difference is most ideal seen in terms of the thickness of the base copper. While base copper for semi-subtractive handling is much thinner compared to aluminum foils used for subtractive flexible circuits; the copper foils for semi-subtractive processing tend to be two to […]

ADDITIVE PROCESSING While fully additive handling is unusual in flex PCB processing, it has potential and also there are a couple of methods to complete it. One of the most familiar approach utilizes a catalyzed laminate onto which negative pictures of the circuit patterns are produced. The exposed laminate can then be layered around accumulate […]
