The Ersa Power Tool does an awsome job and has a very large selection of tips. Keep in mind that the larger the tip the more stored energy. The Waveroom Plus in Londonderry NH sold us our Power tool and we tried everything nothing else worked. Good L

First, what do you mean by "mishandled OSP" boards? Second, we don't like to bake our OSP boards, because of the potential to degrade the coating. Why do you want to bake these boards? Third, why not paste-up a board, reflow it, and assess the sol

I have come across a rash of failed assemblies that have 0805 capacitors and resistors, bottom side glued, wave soldered and washed. Trouble shooter reported touching up the solder joints on a few areas and the boards would pass test. I had a look a

As we recall, they attached something like a placement vib head to the rails. The problem, as you stated, was isolating the board from the vibrating rails during cooling of the solder connection.
