Computer Aided Layout of Ministick Artwork

摘要

A computer program was developed which aids the preparation of artwork for the APL Ministick multilayer printed circuit boards. After the logic diagram has been converted into a system wiring diagram, a wiring list is prepared on punched cards along with a description of the Ministick assembly frame. The integrated circuit flat packs are identified and located on the frame in a similar manner, and a digital computer locates the conductor paths necessary to complete the circuit. This method eliminates much of the time previously required for manual layout of the artwork and makes practical multiple versions of the same circuit layout so as to compare different packaging designs.
