Title: soldering fuses
Post by: dc99 on June 29, 2015, 06:43:51 PM
Finished a really nice box for a friend and had to tear it all apart. I soldered a MHP-TA15-9-77 to each positive of the sled and then soldered the positive wire to the other end. Undoubtedly got them to hot and fried both fuses. Any good tips for getting them hot enough to stick but not fry?

Same rules for soldering any electronic component, no more heat that you need and as little time as possible exposed to heat.  Use a temperature regulated iron set at an appropriate temperature for the work.  For something like that, probably 650 to 700F.  Use 63/37 or 60/40 tin-lead rosin core solder as it has the lowest melting temperature.

If you're exposing the part to heat for too long, you can speed up soldering by tinning the parts before joining them.  Application of a rosin flux prior to soldering speed ups the flow of solder and reduces soldering time.

Thanks Craig. I was at 650 on my solder station but I was having trouble getting them to stick to the positives for the sled. I think that's why I got them to hot. By tinning the tabs first it only takes a couple of seconds to stick. Thanks.

Welcome.  For things like tabs where the solder doesn't stick right away, hitting them with some fine grit wet or dry or steel wool then adding flux will help.  That's how I solder LiPo tabs which can also be a little resistant to soldering.
