You don't have to get the official solderpult, but get a clone that's at least the same SIZE..

The larger chamber and larger plunger offers more suction power.. It's all about the suction..

Fair enough. Sometimes it doesn't suck hard enough for my liking, if I'm honest ( ͡° ͜ʖ ͡°)

How did you manage to ruin them with the pump? I'm genuinely interested. Did you apply too much heat and suck off the contact ring? ( ͡° ͜ʖ ͡°)

Is 20cm length and 2cm diameter a decent enough size for a pump?


BTW, here's a nice video on desoldering:

He also mentions OP's method at the end, heating all joints at once, by using a dedicated liquid (chip quick).

This guy is not using the solder sucker properly..

You don't have to REMOVE the iron, before you engage the pump..

What you do is, You heat, and bring up the pump right up to the soldering tip, You can touch the pump tip to the soldering tip for the duration of the pump action,

The reason is, you're only touching it for a slight second, and the tip of the soldering pump will not melt in that time.

wick usually works for me

the grounded pin takes some extra effort though, especially since products have lead-free solder

too busy to check forums as regularly
pm me if i forget to respond

dunno if i have mentioned this here before, but if you order new switches anyway, i would just cut (carefully to not harm the board underneath) the old switches to pieces, and desolder only the remaining pins.

And i wanna see how you desolder the switches of a mouse like the kinzu v1(where the pin-holes are so tiny, that the switch is already fixated without any solder), by using a desoldering pump no matter the size(BTW i also have the big one, and it nicely sucked up the traces aswell, when i was at the beginning of my soldering career tongue.gif).

If you're sucking up the traces.. it's either Too hot, or indeed perhaps the PCB quality is incredibly low, (often with mice)..


In these cases you gotta be FAST...

that's the problem - you have to be pro to use the desolder pump.
I'd bet 100€ that ppl who start desoldering just for changing some switches, would more likely break out in tears, than to successfully desolder a switch with this method. biggrin.gif
