Solder and flux
Locked
 
|
>>I solder at 800F with a Weller temp-controlled iron and have a little
tub of "Kesler 44" rosin flux on the bench. When reheating a joint I take an Exacto knife with the number 11 blade(the pointed triangular one that is also good for removing splinters, self-mutilation, etc.) and just dip the point about 1 or 2 mm into the goo...about as much as a pile and a half of fly poop...if you are familiar with that... and apply it to the soldering point before heating.<< An excellent method...In the absence of rosin flux, remember that fresh solder contains flux...Reheat the reluctant joint with a clean, hot iron then just TOUCH the tip-joint juncture with fresh solder and the joint will quickly liquify, allowing whatever rework is necessary, be it the removal of excess solder or eliminating a cold joint... Having better means at my disposal, I seldom use solder wick, but I find that it works best if you lay the wick down over the joint, place the clean, hot iron on top of that, and then add a dab of fresh solder...Wait a second or two for things to flow and the wick will usually suck up all the excess...

I find solder wick works much better if you wet it first with flux: I use a flux pen from Chemtronics #CW8100

Some brands of solder wick come was pre-filled with flux and have a
waxy feel. I recall when I was working in an electronics lab in the 1960s, we had little bottles of liquid flux with an eyedropper-type syringe attached to the cap. It was easy to apply just a drop or two.
