Having trouble soldering wires to a JM215A. Are there any tricks like using flux? The areas involved are so tiny I bought a magnifying glass but still having trouble. Also when completed should I test the pin outs with a multimeter? What should I be looking for? Thanks! Jeff

use a continuity meter with a ring sound plus you should get near zero ohms resistance as its a small short cabble you need to tape doen the cable so it does not move its also better if you remove the old solder and clean the joint with some solder brade with none clean flux then place the cable next to the pin tape in place and solder with a 0.5mm solder as if its to thick you will over solder it then solder together making sure it flows properly onto the pad and pin and cable repeat for the other 3 connections bell out with continuity meter to make sure you have a circuit if it rings loud and clear you have a good joint connection between both point

Try not to overheat the joints. You can delaminate the traces if they get too hot. I like to use a flux pen in tight areas, but most importantly use good solder. A nice thin high silver content solder works best for me. Rosin core solder can gum things up a bit and it involves a little extra cleaning afterwards, but it works. If you're going to do a lot of soldering in the future it might be wise to get an adjustable heat station like a Hakko. It makes a world of difference to have the right tools for the job.
