Flame retardant copper-clad phenolic paper laminate. IPC4101 detailed specification number 02; TgN/A.
Flexible PCB Classification
There are adhesive flexible PCBs and non-adhesive PCBs. The price of non-adhesive flexible PCBs is significantly higher than that of adhesive flexible PCBs. However, non-adhesive flexible PCBs offer superior flexibility, bonding strength between the copper foil and the substrate, and pad flatness compared to adhesive flexible PCBs. Consequently, they are primarily utilized in applications with stringent requirements, such as COF (CHIPONFLEX, bare chip mounted on a flexible board, necessitating high pad flatness), among others. Due to their elevated cost, adhesive flexible boards remain predominant in the market for flexible PCBs. Given that flexible boards are predominantly employed in bending applications, improper design or processing may lead to defects such as micro-cracks and open solder joints.
