Re: Repairing plated through holes.

 

Delco used the 'griplet' in one or two model years. They were a disaster. They sent out a service bulletin, and paid a set price to repair those AM/FM radios. They were plated steel, so you had to run wires through them.

I have some of the Pace eyelets out in my shop, but the roof lead in the parts room, and the floor was particleboard, covered with old carpet so the shelving went through the floor and stuff went everywhere. A local vocational school used the Pace system, and a kit of materials were issued to each new student. The teacher gave me the leftovers from kids who dropped the course.

still under compression.
This fused the flared part of the eyelet to the lands.
Motorola used eyeletted boards in some of their two way radios.
This was the major source of failure as the eyelet solder connection
broke free of the lands.
The fix for this was to resolder all of the eyeletted connections on
both the top and bottom of the board.
