1. Recommendatory process condition for press:

 

Press method	Press temp.	Pressure	Time for press	Temp.for de-pressure
laminating	160ºC~175ºC	15~20 kgf/cm2	45~60 mins	Under 60ºC
Fast press	170ºC~185ºC	20~30 kgf/cm2	2~3 mins	Need Post-processing

1. When fast press, need post-processing, suggested condition:145~155ºC for 1 hour
2. Choose proper press method according user's own technical parameter, ensure the coverlay film is well bonded to the covered substrate and meet the expected FPCB's quality demand.
