Copper Foil For Coreless board
We propose two kinds of copper foils and new production method, aiming at improving productivity and yield in coreless board process.
PaCuT
PaCuTis the application product of cut foil which shiny side of two Cu sheets are attached to each other by glue.
PCS or PCM (Peelable Copper Foil on Shiny side or Matte side)
PCS or PCM are peelable copper foil with peelable organic material coated on copper surface.
PCS or PCM can be laminated with resin(e.g. FR-4) by ordinary PCB process and also released easily from the laminated resin at any timing.
Application
Coreless PCB, Bendable PCB
Potential applications of PCM
Laminating & Peeling off PCM, roughness of Cu foil is transferred onto resin for adhering other materials
Application proposal of matte replica forming
For conductive paste
For Semi additive process
For facilitating adhesion to hard-to-bond resins
