1960s and 1970s
Boards were designed using 4:1, red-and-blue line vellum method for hand-taping components and tracks. A precision camera then produced the 1:1 negative manufacturing film. An experienced designer could lay out and tape a board at the rate of about two hours for each equivalent 14-pin IC on the board.
Pads were about 70 mils or greater, and traces and spacing were 25 mils. Boards were typically double-sided, with only a small percentage of multilayer boards, usually no more than four layers.
