 |
|
Given a DB-44 with high density pins......
What's more reliable:
1.) Machined pins crimped with DFM AFM8 4 point crimper
2.) Formed pins crimped with open jaw hand crimper and soldered, w/
insulation crimped also.
3.) Formed pins only crimped with open jaw hand crimper

I don't think I've ever used anything but option #1 on a high density
D-Sub. By formed I'm guessing you mean open barrel? I didn't even know
they made high density pins like that...I've never bothered to look.
You can't do much better than option #1. You get strain relief from the
backshell of the connector. The Daniels crimper is EXPENSIVE, though. If
you want them crimped and you're only making a couple of cables, it's
probably way cheaper to just have someone like Stein make them for you.
If you really want to solder them instead, I would use a connector with
solder cups on them.
I will say, though, Daniels makes a NICE crimper! I'm a tool junkie and I
can't resist stuff like this.

When installed with the proper tools by an experienced
user, all of these technologies will provide useful
service. However, the machined pins and 4-point crimpers
are as free of process-driven error as any of the technologies.
I've pitched all my open-barrel tools and pin inventory.
The ease with which the best-we-know-how-to-do can be
accomplished with the machined pins is just too much to
pass up.
You bet.
