Abstract
A method of manufacturing a press pad is disclosed. The method includes: providing a planar pad having a first surface and a second surface opposite to the first surface and a release film sheet, the release film sheet including a polyimide-based film; cleaning the planar pad, the cleaning including electrostatically removing particulates from surfaces of the planar pad; and attaching a release film sheet to the first surface of the planar pad, the release film sheet being attached to the first surface using an acrylic-based adhesive containing thermoplastic polyolefin and methyl acrylate.

A press pad for use in lamination of multi-layer circuit boards, the press pad comprising:
- a planar pad having a first surface and a second surface opposite to the first surface;
- a sheet of release film coupled to the first surface, wherein the release film sheet is coupled to the first surface using an acrylic-based adhesive containing thermoplastic polyolefin and methyl acrylate, and wherein the release film sheet comprises polyimide-based film.
A method of manufacturing a press pad, the method comprising:
- providing a planar pad having a first surface and a second surface opposite to the first surface and a release film sheet, the release film sheet including a polyimide-based film;
- cleaning the planar pad, the cleaning including electrostatically removing particulates from surfaces of the planar pad;
- and
- attaching a release film sheet to the first surface of the planar pad, the release film sheet being attached to the first surface using an acrylic-based adhesive containing thermoplastic polyolefin and methyl acrylate.
A system for manufacturing a press pad, the system comprising:
- a first material handling unit for receiving a planar pad;
- a second material handling unit for receiving a release film sheet, the release film sheet having an acrylic-based adhesive containing thermoplastic polyolefin and methyl acrylate applied to one side;
- and
- at least one roller coupled with a drive, the drive rotating the roller to pull the release film sheet into contact with the planar pad to attach the release film sheet to a first surface of the planar pad.
