Weller Micro Soldering Kit and Filtration Unit - first test of desoldering tweezers

Jan Cumps

Testing the desoldering tweezers. I removed a set of SMD components from a multi-layer board:

  • I just did a new rework test. Remove 3 0402 resistors from a multilayer board, and replace them.

    The video above was done right after unpacking the kit. This time, I have a week of experience. You may notice that I'm more comfortable with the tweezers and iron than in video 1. They now feel natural.

    what was used from the kit:

    • the station, at 380° C. Both for tweezers and iron.
    • conical bent tip solder tweezers (RTWMS 004 C X)
    • bevel micro solder tip 0.4 mm (RTM 004 B MS)
    • micro solder iron
    • tweezers
    • auto tip cleaner (not in view)
    • fume extractor (partly in view)

    I've found that using smaller de-solder braid on smaller pads is worth the trouble of having several different sizes. The tiny bits you need for 0402 parts have trouble getting enough heat into the thicker braid.

    I have smaller braid, just not handy while filming Slight smile. For some situations I clip off a piece and drag it over the pads with tweezers. I'm also a pre-heater fan.

    The micro solder iron hasn't got a lot of heat capacity. For anything sizeable (braid, large copper area), you notice a little delay before the solder melts. Unless you go real high temp. The irons are at their best with tiny components in tiny areas.
