One of many first instruments that’s added to a toolbox when engaged on electronics, maybe moreover a multimeter, is a soldering iron. From there, soldering instruments could be added as wanted akin to a sizzling air gun, reflow oven, soldering gun, or desoldering pump. However typically a soldering iron is all that’s wanted even for some specialised duties as [Mr SolderFix] demonstrates.

This particular approach entails eradicating a big connector from a PCB. Usually both a warmth gun could be used, which could harm the PCB, or a tedious course of involving a desoldering instrument or braided wick is likely to be tried. However with only a soldering iron, a couple of items of wire could be soldered round every of the pins to create an enormous solder blob which connects all of the pins of the connector to this wire. With all the things linked to solder and wire, the soldering iron is just pressed into this amalgamation and the connector will fall proper out of the board, and the wire can merely be dropped away from the PCB together with a lot of the solder.

There may be some cleanup work to do afterwards, particularly eradicating extra solder within the holes within the PCB, however it’s nothing a little bit wick and energy can’t handle. In comparison with different strategies which could require specialised instruments or much more time, that is fairly the approach so as to add to at least one’s soldering repertoire. For some extra superior desoldering strategies, check out this methodology for saving PCBs from some thermal stresses.
