I killed all the chips on the board by accidentally applying 26.0V instead of 2.60V ;-(

The good thing though: ChipQuik works like a charm.

  • I was pretty much cringing while watching you clean the excess solder with the desodlering wick. The way how you are rubbing it along the pads would be the fastest way to destroy them

  • @DOTiSOalt: seems like everybody else is using abrasive scratch pads instead of solder wick. But what do I know.

  • Good work!

    Is ChipQuik reusable??

  • Hmm.

    If you took as much of it as I did in this video, the remaining blobs might work a 2nd time. Normally you only need very little of the alloy to soften the bond. I'm not sure if reusing makes any sense in that case. Unless you use it by the pounds.

  • Make sure you put the new chips on the right way!

  • Hell yeah, can't have unfluxed solder / wick. Throw it away or use it on the xmas tree (and then throw it away).

  • It is a brand name for a special low melting point alloy. Normal solder will solidify withing 1 or 2 seconds after you remove the tip, whereas this stuff stays soft for 10 seconds or more. You mix it with the solder on parts you need to remove and just push them off as shown in the video. A starter set costs 16$ (lots of alloy, the amount of paste flux is a bit on the low side).

  • Of course.

  • Hm, I haven't seen any of these lately. It is basically just a "normal" analog regulated power supply upgraded with a small microcontroller to do some extras (like the keypad and RS232 interface to a PC). I think you'd have to invest about >200 for something like it. Nowadays you'd get a lightweight switching power supply and not a 10kg brick. But it will last for many many years, so the price is not that bad.

  • I got it more than 10 years ago, so I don't remember ;-)
