Prototype fabrication of printed circuits - low cost fabrication of small quantity circuits

摘要

The printed circuit making kit has a small case whose interior after closing of the cover forms a chamber, and having an electric light source which permits the revelation of the circuit after exposure and chemical action on the resin covering of the plate. On the inside of the case separated from the chamber is a compartment which contains all the materials necessary for covering each plate with photo sensitive resin. The light source in the chamber is an actinic flourescent tube. Within the light chamber are two blocking strips which hold the plate in position against one of the chamber walls. The compartment holding the chemical products has housings for each product, these products being held firmly in their housings.
