Description: 1960s ~ Catalog / Sales Brochure + Price List ~ Techniques inc - Printed circuit kits Printed circuit boards (PCBs), especially high density and many layered, were still a relatively new technology in 1960s. Point-to-point wiring was still a large part of most products in the commercial, military, industrial, and aerospace worlds. Producing artwork and contracting for a lot of PCBs was rather expensive, especially in small quantities. Many people, made quite a few single- and two-sided boards using photoresist pens and self-adhesive tape and pads, then bathing them in an etchant solution of ferric chloride. Through holes were made on a drill press and then traces and pads were tinned with flux and solder laid down on all exposed copper. Pseudo plated through holes were made with short pieces of bare wire running through the top-to-bottom holes and clinched down to the pads. Solder mask was not needed for small quantity runs, especially at a time when the smallest distance between component leads (i.e., pitch) was 1/10 inch for DIPs. Comes form a former missile engineer for the US Air Force.Was employed under this position during 1950's and 1960's, may have continued on afterwards, all the paperwork I have are from that period. Well cared for. pages are clean and crisp.
