It is always best to ask the manufacturer of the connector what the
requirements are for a go assembly. I would hope they have an assembly
instruction and qualification data. They should also provide information
as to what cable can be used in their connector.

Subject: Re: [TN] Crimping requirements - coax cable
Hi Linda, thank you for your reply.
I had already looked into section 13 of IPC/WHMA-A-620, but there are
only two crimp configurations - clamped ground ring and crimped ferrule
- whereas my coax cable was crimped onto an open barrel crimp almost
identical to that found in sect 5.1 of the IPC spec.
Hence my confusion: in the absence of specific requirements for coax
cables mated to open barrel crimps, should a coax cable then be treated
like a regular wire and follow the accept/reject criteria of 5.1.3?
Best regards,
Julien Meyer

Julien,
Check out the IPC/WHMA-A-620, page 13-1, there is a whole section on
Coaxial Cables.

Subject: [TN] Crimping requirements - coax cable
Hi TechNetters,
Does anyone have experience with the IPC requirements for crimping coax
cables?
We received a shipment of crimped coax cables where the conductor crimp
was not fully closed. Therefore, a substantial section of braid was not
captured by the conductor crimp.
If this were a regular wire, it would fail according to IPC for all
product classes, but since it's a coax cable, I'm a little less certain.
I posted some pics here:

Could you advise?
Best,
