What is PTF(Polymer Tick Film)? PTF introduction

PTF samplePolymer 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.

What potentials cause make HeatSeal Connector peel off?

LCD use HSC solution and missed segment

Recently, there have been numerous instances of segment defects appearing on the display of the HSC (Heat Seal Connector) solution LCM, as reported from the field. Our experience has shown that the reliability of HSC bonding is not satisfactory, particularly for industrial products. This is primarily due to the HSC’s tendency to lose its adhesive properties over time, ultimately resulting in a loss of contact between the PCB and HSC after extended use.
