Abstract

The manufacturing of organic based chip carriers (in specific, PCB material) is often done in reel to reel or strip form for the purpose of automated handling and processing. The cost and complexity of tooling required to excise these carriers from these strips needs to be minimized. A simple design method for rectangular formed carriers is described to aid in this purpose and to allow easier handling after excising.
