Discussion Overview

The discussion centers around the choice between solder cup connectors and crimp connectors for creating an in-line 37-pin D-Sub connector. Participants explore the reliability, ease of use, and application considerations of each method.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants express a preference for solder connectors, suggesting they provide a more reliable connection.
  • Others inquire about the specific application and whether pre-made cables could be used instead.
  • One participant notes that solder cups are particularly advantageous for making only a few cables, as they do not require specialized tooling or adherence to strict specifications.
  • Concerns are raised about the reliability of crimping, which requires the correct parts and tools that can be expensive.

Areas of Agreement / Disagreement

Participants generally express differing opinions on the preferred method, with no consensus reached on whether solder cups or crimp connectors are definitively better.

Contextual Notes

Participants mention the need for specific tools and adherence to manufacturer specifications for crimping, which may limit its practicality for some users.

If I'm looking to create an in-line 37-pin D-Sub connector (i.e. not board-mount and not panel-mount, but connecting two groups of wires to each other), is it better to use the connectors with solder cups, or the ones with holes for pins and sockets that have been crimped onto the wires?

...or does it not matter?

...or should this type of thing not be done at all?

I prefer using solder connectors. IMO you will get a more reliable connection.
 
I also prefer solder cups, especially for making only 1 or 2 cables.

To crimp reliably you have to make sure you have the right parts and follow the manufacturer's specifications which often require tooling which can cost several hundred dollars.

With solder cups you just have the one part without separate pins and soldering doesn't require anything special assuming you have solder and an iron handy.
