| Abstract: | This paper mainly illustrated the technology of production process of super thick copper 411.6μm（12oz/ft^2） multilayer PCB. It effectively solved the technical problem of etching hardly and difficult resin filling by using copper back-etching, laminating and positive etching. The quality of etched line and lamination was assured. It greatly improved the quality of the productions, and meet the customer＇s special requirements on super thick copper. |
