Solder or super glue ?

Hi, I have a 10mw 532nm laser module that has a crack/break on a pin just before it connects to the board. Do I need to solder this back together or glue it or something or is it supposed to be broken there ? I probably cracked it from jigglin it too much trying to see if it would break . Anyway, I was thinking of hot glue or super glue because I’m not good with a welder or torch n stuff. Thanks.

Hi,
Get yourself a cheap soldering iron let it heat up and lightly drag the point over the break. It doesent have to be solid just a small bridge.

Cool, thanks, I might as well grab a little iron and then I can use it for dabs, too.
I got an expensive cheap laser pen that was pretty much doa so I took it apart and now I learn about lasers. Thank you.

You can never glue something like this. Glue is not conductive, so can never replace metal. Soldering is fairly easy. Just use a good flux cored electronics solder, NOT plumbing solder or flux. Clean the tip , with emery cloth if needed, to be able to see the copper. Let the iron heat up, put a little solder on the tip to "tin" it. If you are fixing a crack at this point, just touch it to the break long enough for the solder to melt and flow. If it were a new connection, I put the solder on top, heat it with the iron, and when it starts to melt, add enough extra solder for a good connection, but not enough for a huge blob. The biggest mistake is not letting what you are trying to solder get hot enough, and you end up with a cold, bad solder joint. BUT... You also have to watch to not let things get too hot either, as the heat can damage semiconductors.

Hello Gatrezal,

I deleted your other thread regarding laser hair removal thread as it can be considered spam.

Thanks! :)
