Hi Carol, does that happen also when you solder them with an iron ? That�s what I did with some joints using hightemp solderwire and couldn�t notice anything you mentioned. What Brian and Dave said should be worth considering. good luck Wolfgang

Thanks Russ. You were right I looked one page too far. We can meet (A,B,C,D). To meet the 75% of (E) the annular ring will have to be scraped. Your help was much appreciated.

If you find it at the end of your process and you find no defects, work on something else. Now if you are a smooth talker and seek a little adventure in life, you might be able to finesse this thing into a road trip to take a tour of your board fa

Hi, I tried to use high temperature solder (540 - 570F)to connect four spacers on the board. The solder mask around the spacers wrinkled a lot.I can even see a few bulbs around it. I use hot plate and solder rings. After hot plate is heated to appr

Did you try Techspray Wondermask W? It is water soluble and can probably be transferred from the bottle to an EFD type syringe for dispensing (we use the P and the PL that way). As far as if it will swell through the reflow, I don't know. We don't us
