HotBar FPC Design Notices

The HotBar soldering is a kind of selective soldering solution where connect two pre-fluxed, solder coated parts by pulse heating element, call a “thermode”, with proper temperature to melt the solder and re-solder. Applying a pressure and contacting on the … Continue reading

Design for Flex cable(FPC) Trace Pattern

Many FPCB designer are not familiar with the manufacturer process and limitation.  I always found design does not meet DFx requirement and insist on their design and finally bring lot of quality issue after mass production. Here I ask FPCB … Continue reading

Screen-Printing on PET(PolyEthylene Terephthalate) notices

The PTF uses silk-screen to print the silver and carbon combination conductive inks on PET substitute to reach lower cost purpose as compare with FPC (Flexible Printing Circuit). Unfortunately, the screen-printing still has some ability limits. Especially that it has … Continue reading

What is PTF(Polymer Tick Film)? PTF introduction

Polymer Thick Film (PTF) flexible circuits are manufactured by screen-printing conductive ink onto flexible substrates such as PET (Polyethylene terephthalate). It can be single layer or multi-layers circuit by further screen-printing dielectric materials as insulating layer and applying through-hole technologies. … Continue reading
