IPC-7721, Section 6.1, Jumper Wires, Jumper Wire Selection #5 states: "Recommended wire is solid, insulated, plated copper wire, 22 to 32 AWG with a heat resistant insulation. Wire with tin-lead plating may be restricted due to environmental laws."

We are soldering wire 26AWG to jack socket. However after went through washing, baking, coating, curing processes the wire breaks (at joining point with jack socket) during wire dressing. We have tried to increase and decrease the solder amount but r

I am having a problem with wetting on some feedthru wires. The problem seems to be contamination on the wires, due to the fact that the problem seems to be wire lot dependent. I have analysed it using SEM and come up with very little. Is there ano

We use 30 and 32 gauge PTFE wire. The insulation will not melt with normal hand soldering temps. The wire was made by Thermax/CDT. Their phone number is 800-423-5873. The only problem with the wire is that is hard to glue to the board. We use Ta

I have never used Manganin wire. I understand it is difficult to solder. Should we use a move active flux. It will be a .25mm, PTFE insulated manganin wire spliced to thermistor wires. Thanks coeps

I agree with AFlex. Don't tin stranded wire that's assembled into a screw terminal block. I believe the reasoning has to do with avoiding stress on the wire metal caused by different expansion rates of the solder and the wire. BR davef

We are using KIC (kicthermal.com) in reflow profiling. It uses thermocouple wires about 0.5 meter only each point. Previously, Winkic the machine built in software which requires about 5 meters wire. No need for the operator to stand there and feed t
