content: It is my last choice. The pushbutton/LEDs will be under, facing the breadboard. I am going to try to remove the headers with a lot of solder wick and patience...I will order one or two more kits just in case.

content: I've done the same lots of times, occasionally even intentionallyThey look like standard 0.1" single row headers so they're worth considerably less than the board, just clamp up the board, heat a joint and pull the pins one at a time, the header will be ruined but the board will be good.

content: It was easy to wick most of the solder off. The trick will be to wiggle the pins loose of the last bit of solder. I will keep working on it later today.The headers are low cost (~$1.40 ea.) compared to the PSOC 5 kit ($10), but not as cheap as the standard pin length ones. In fact I have found rather difficult to find a source for the 1x40 female extended length ones.I have another kit on order. If I fail to remove the headers I will snap off the kitprog and use the kit as a target for a dedicated project. Not a big deal.

content: After buying a Hakko 808 several years ago I can only wonder how I ever got by without it. Wick is horrible for this kind of thing.

Do this one pin at a time, as CJay said. Once all the pins have been removed,thenuse a solder sucker to remove the solder.

content: Quote from: tooki on June 02, 2017, 09:14:12 pmDo you really mean pull? Can you pull a female contact from the back ? I would think pushing from the back may work. Either way, I do not currently have a vise setup for electronics. It may be time to get a decent one.

It changed my life and made me a much happier person (insert random praise here).

content: Quote from: evb149 on June 02, 2017, 09:57:27 pmIt has soon became obvious that with the tools I have, it is the only option. With some CHP170 wire cutters I cut in between pins and removed the larger plastic part. I had not realized it, but the body is made of a layer similar to the one in male headers, with cutting indentations and then a larger piece on top. I had to cut in two passes. Then desolder/pull pin by pin and wick and cleanup.Now is to be seen if the kit still works, after all the heating torture and mechanical stress.One learning point is that I need a decent vise, so I just ordered a PANAVISE 381.

content: Quote from: Back2Volts on June 02, 2017, 09:38:49 pmThis kind of thing but with long pins?It'll take a bit more care but they're not too difficult to get out one at a time, trim the long pin close to the board, break the plastic (heat helps, you can also usually deform it enough with pliers or cutters) and then pull them, one at a time.You can get pin to pin headers to suit them though so that may save you the effort.
