Abstract
A novel process for fabricating metal clad laminates used in the manufacture of printed wiring boards. The process which eliminates multiple use separator plates within laminate books during buildup and pressing, utilizes a sacrificial separator sheet between copper sheets and wherein the separator sheet remains intact throughout the pressing and cutting steps and is finally removed after the laminates have been sized to the desired dimensions. This process provides time and cost savings, as well as a significant increase in quality and quantity of the laminates produced.
