PC board design and fabrication using Schematics, PADS-PERFORM, and a laser printer

摘要

The software packages Schematics from MicroSim Corp. and PADS-PERFORM from PADS Software Inc. have been interfaced to give students an integrated environment where they can create schematics for documentation, simulate circuits, and design printed circuit boards. The software packages are available in evaluation versions. The circuits are limited to approximately 25 components but this is not a limitation for undergraduate projects. A package of parts has been developed at Northern Arizona University that contains part symbols and package outlines for parts in a "standard" lab kit. PADS-PERFORM can output artwork on the laser printer. A method for using the laser printer toner for resist when etching the boards is discussed.
