Re: [PSES] Shrink-wrap on soldered connections

Don't believe the cost differential is significant - but cost control is only an ancillary activity and only in the general sense. But I've never had a failure except for vibration induced and even then it was generally the copper but the wire still kept from flopping around. QA practices when

Re: [PSES] Shrink-wrap on soldered connections

Thought about this and realized that I have never seen crimped connector fail where the connector components have test certificate, and where the crimping tool is subject to recurring calibration, and where the correct wiring materials implemented. And have never used crimping tools or

Re: [PSES] Shrink-wrap on soldered connections

I agree with Gary, but the quality depends on wire type and match between wire and crimp. Also the tool quality (if the right tool is used at all) is essential. Crimps are suitable for stranded wire only, and the wire need to be inserted far enough. Crimps are subject to a number of failure
