#1 De-soldering tool.

Post by pre65 »

I need to de-solder lots of pins on a PCB.

I have some de-soldering braid, but I think (perhaps) that a tool such as this might be more useful in view of the need to save the actual board for re-use.

Any other suggestions welcome. :lol:

EDIT This is what I'm trying to do.

Depends on the type of solder used but I've found sometimes its easier to de-solder a many pin device/plug/thingy by adding fresh solder in 1st then remove the bigger blob, sounds daft but its worked many many times. Also, sometimes just adding solder in allows the the heat to spread throughout the joint and you can slowly (and carefully) remove a many pinned device with VERY gentle leverage from the watch makers screwdriver under the body of whatever you're trying to unsolder and work your way along the connecting pins. You have to be very careful not to damage the print on the PCB natch.

Once the 2 are seperate, then you can clean things up with a solder pump like this http://www.ebay.co.uk/itm/new-Solder-Su ... 4d1984031e and/or braid.

The braid can oxidise and 'go-off' if you dont keep it clean and away from open atmosphere BTW. It makes sense to keep it in a little zip bag we've found.

Thanks Dave.

One problem is that the component side of the board is not accessable. :(

What Dave said I mostly apply heat while applying leverage under the component, worked for me 90% of the time for the last 40 years. :D

Did try a solder sucker once but found it too frustrating compared to the 'crowbar' technique.

I'm going to try a games controller first just to make sure the thing is worth persevering with.

What Dave and Mike suggested has worked well for me over the years as well. Slow and steady alternating heat and leverage usually works.
