PCB DIP

This is a way to make a PCB with DIP legs.

The legs are thin & flat like chip legs, and so do not exceed the specs of DIP sockets. Normal square pin headers are really not good for DIP sockets. The pins are too fat and stretch out the socket contacts so that the socket no longer grips real DIP chip legs as firmly. Machined round pins are smaller and better, but even they are still almost twice as thick as chip legs. There are some special "micro pins" from Mill-Max and at least one other manufacturer, but even those are technically thicker than the specs that socket data sheets claim to support officially.

The completed PCB is very low profile and fits in many places where a larger board with pin header insulators and shoulders do not fit.

The SIL leadframe that provides the pins: TE 1544210

The size of the drill holes is very close to to the size of the pins, so that the pins barely fit, which helps keep the pins aligned perpendicular to the board.
