Hi, I have an INTERMITENT error on my FUJI IP-2 that cause to me many headaches. The error is " SERVO NOT GOOD". In the books, it means that it is relative to servo amplifier. But I can't assume that is the problem because sometimes the machine wor

INDIUM 92J solder paste feedback

Electronics Forum | Mon May 09 15:27:05 EDT 2005 | jdumont

We used the 92J a couple of years ago for a while. It performed very well for us. However when we started batch cleaning our assemblies the 92J post solder residue was not very easy to remove so we switched to Kester 256 which cleaned better. JD
