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; cleaning the planar pad, the cleaning including electrostatically removing particulates from the first and second surfaces of the planar pad; and attaching a first release film sheet to the first surface and a second release film sheet to the second surface, the release film sheets being attached to the first and second surfaces 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 first sheet of release film coupled to the first surface;
- and
- a second sheet of release film coupled to the second surface,
- wherein the first and second release film sheets are coupled to the first and second surfaces, respectively, using an acrylic-based adhesive containing thermoplastic polyolefin and methyl acrylate, and wherein each of the first and second release film sheets 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, a first release film sheet, and a second release film sheet, each of the first and second release film sheets including a polyimide-based film;
- cleaning the planar pad, the cleaning including electrostatically removing particulates from the first and second surfaces of the planar pad;
- and
- attaching the first release film sheet to the first surface and the second release film sheet to the second surface, the release film sheets being attached to the first and second surfaces 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 first release film sheet and a second release film sheet, the release film sheets each 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 first and second release film sheets into contact with the planar pad to attach the release film sheets to respective surfaces of the planar pad.
