For years I have done repairs on a variety of high-end connectors from Lemo, Fischer and others for the broadcast and entertainment industry. While they are fantastic in a lot of ways, they have very tight pin pitches and repairs are difficult.
I am now in a position where I need to manufacture these from scratch in modest quantities which will clearly require a more engineered approach from what I have hacked in the past. Commercial assembly houses are available in my area but they are not practical for short turn around and constant changes which is our normal way of working. Wire prep is one of the first challenges. The jacket, shields and conductors have to be precision prepped to have a hope of a good final termination. I have a variety of typical wire cutting and stripping but they are not good for the very fine wires- especially being stripped to a precise length.
Any recommends on production quality hand tools for fine wire prep? I have a thermal stripper but it is only effective to about 22ga and I would be in the 26-28AWG range with about 10-20 conductors. Maybe there is a thermal stripper specifically for small wires? On most connectors, the main jacket of the cable and the shield is only stripped a very short distance from the ends of the conductors. This makes it really difficult to strip the wires that are bundled fairly tight.
The next challenge is more procedural. Getting the tiny conductors soldered to the tiny solder cups. Some connectors are crimp pins and some are solder. Start from the middle and work out? Are there any fixtures, grippers, or tweezers that can be the most helpful? I have enough experience to know that this is a practice, practice, practice type of skill but I would like to minimize the number of sacrificial connectors and hair pulling. In the end, I would like to develop a training program for an employee too.
How do the professionals do this?
