Title: $35 solder sucker
Post by: pbj on April 28, 2018, 05:03:07 pm
So, you take a $22 desoldering iron with bulb sucker, pop off the sucker, slide on some extra home brew tubing, and keep it tight with a zip tie.

Then you go to Harbor Freight and get their $12 foot pedal (itís in the sandpaper section of all places).

Then you dig some type of pump out of the trash.  I used a foam block that I whittled down and drilled a hole through as well as a prolific amount of duck tape to join the vacuum and my tubing.

Heat up solder, wiggle component leg around, step on pedal. Step off, let warm up for four seconds, repeat from another angle.  I went very slowly but am beyond pleased with my results.  I should have done this 20years ago.

This is $300 tool result for $35.  To be honest, the experience actually went better than doing a similar repair with a Hakko 808.  The hole is so small on the desoldering iron that I think you could get away with a much more modest pump than I used.  After I did 30ish pins I took off the tip and cleaned the chamber but that wasnít really necessary.

Why the hell havenít more people done this.....chop, chop, BYOAC.

Very nice. What board is that you were working on?

This is amazing.  I've needed a desoldering tool for a long time, but been hesitant to drop big bucks on the good ones.

I'll try it next month... THANKS!

System 6 driver board from my Firepower.  Itís got a weird problem with one row and one column of lights not working.  I dropped in a machine pin socket and a new PIA 6801 from China.  Unfortunately that didnít clear the issue, but I also didnít create new ones.

With Alien Poker 100% thanks to the miracle of 3D printing, this is the only issue in my collection.  Thereís a couple more suspect chips to replace and then itís time to consider the CPU board.

Because my Hakko desoldering gun suits me much better. I applaud your jankiness, though. It suits you.

The dull and uncreative have made some wise remarks about my setup being ungrounded.  So, I suppose the next step is to alligator clip a wire to the desoldering iron, and attach the other end to a nail stuck in the ground.  I wouldn't ordinarily bother but the addition of the vacuum cleaner, I suppose, makes this a greater than 0% risk.  Do what thou wilt.

Pretty much what my friend the electrical engineer said.  Apparently there's virtually no risk with this setup.

Do what thou wilt.

I got all excited to make one of these, and did some research.... First just buy one, bit spendy for quality. Second the concept, Apparently temp control is a big deal in controlling heat, (and different suck tips for different projects, and maintenance seems to be a constant battle beings the solder has to go someplace,....On a budget the arrow seems to have some good reviews at around a buck and a half. Jennifer for now will probably just stick with her solder tape as it has served me well ,.... Thanks for the plans though Pbj, it is a fun idea.
