I have just started an assembly which uses a 16 mil pitch QFP. We ran on Saturday, using a type 3 solder paste. (working Sat's really sucks) We really struggled with paste release after the stencil sat for 15 minutes without printing. Apertures clog

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
