Looking for "Wisdom of the Crowd"
DB connectors solder vs crimp.=C2-=C2-
Preparing to do some panel wiring and will be using several DB-9, DB-25, &
DB-37 connectors and seeking input on which is the better method for connec
tion.
My initial thought is that soldering will produce higher quality results be
cause:
1. The pins are molded into the connector body, making them more robust (?)
(stronger than the "snap-in" architecture of removable pin?)2. Solder conn
ections have higher mechanical strength and excellent electrical properties
I have mostly used solder-type connections and most of those on circuit boa
rds.=C2- Not much experience w/ crimp-type.=C2- (I'm pretty handy with
a soldering iron)
Looking for insights from people who have used both.
TIA,

Done it both ways and I like the solder method. Use a small iron, pre-wet the
D-sub cups with a tiny dab of solder, prepare the wire ends, one-by-one heat each
cup and insert the wire in the cup.

Hi Jeff,
I started soldering as a teenager, and worked as an electronics tech in
at least 3 different 'disciplines' during my working career. Still
soldering after all these (50+) years. I used a few solder-style DB
connectors early in my build, but switched to machined crimps early and
have never looked back.
Honestly, while the crimps are quite a bit more expensive, they are a
*lot* faster than solder style, and get even faster when you need to
're-pin' those two wires that got soldered in the wrong place. Also
several orders of magnitude easier once everything is installed in the
plane, and you need to add wires to interface a new widget.
I'll solder/heatshrink a splice in a heartbeat, if I can get the iron to
it, but for multipin connectors like DBs, etc, I find the crimp style
much more practical.
Bonus tip: Any time I install a new DB connector, I use an engraving
tool to make human-readable beginning and ending numbers for the top and
bottom row of pins on the metal shell of the connector. Makes it much
quicker when I start counting pin positions for the next wire,
especially when I've forgotten where '1' is on a male vs female connector.
YMMV, etc etc
Charlie

Soldering on the bench is peaceful soothing satisfying work. It's harder to
solder connectors that are attached to wires that are in the airplane.
Crimp works too but costs more, and it's quicker. If you have to make
changes, crimp is easier.
Properly done, either will be fine.
I soldered most of my plane then did a few crimps

I second Charlie's post.
I got a used Daniels AFM8 crimper on ebay for a fraction of new. It needed
a little TLC but it works like a champ. This positoner kit works well
too:

Hi,
I wired my airplane as per figure Z-16 Rotax 912/914 system of bob Nuckolls book.
I use an off-on-momentary on switch as ignition switch. Today I made a starting
test and the starter doesnt stop starting until I close the master. I dont
understand what happens. Is it the wiring? The starter solenoid? Im confused.
Any help would be appreciate.

No doubt the Daniels is the absolute best. But... 'Better is the enemy
of good enough'.
https://bandc.com/product/d-sub-machined-pin-crimp-tool/
or even
https://www.steinair.com/product/4-way-indent-crimper/
The Steinair crimper expects a change of positioner for hi-density pins,
but I've found that simply holding the pin at the correct insertion
depth works fine when I only need to crimp a couple of the small ones.

Hi,
I think I find my problem, I withdrew the diode on the starter and the starter
works fine.

Solder pins can not be replaced if damaged in the future. Solder tends to
travel up the wire, meaning that the wire is stiff and prone to vibration f
racture where the solder ends. My vote is for crimped connectors. Just be s
ure to use a quality crimping tool.

Looks like we have a good mixture of experience-based opinions.
ArtZ, I especially like the "Zen" approach to soldering... and completely a
gree.=C2- In addition, there's the rosin core "incense".
One advantage to soldering is that it is easier to get 2 wires soldered to
one cup, when necessary.
Thanks to all,
