  1. Recommendatory process condition for   press:
 
Press method Press temp. Pressure Time for press Temp.for de-pressure
laminating 160 ºC ~175 ºC 15~20 kgf/cm 2 45~60 mins Under 60 ºC
Fast press 170 ºC ~185 ºC 20~30 kgf/cm 2 2~3 mins Need
Post-processing
  1. When fast press, need post-processing, suggested condition:145~155 ºC 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.
