You could also try the ipclistserv "tech net". It is an email list and there are a lot of design engineers that maybe willing to lend you a hand. It kind of reeks to up but maybe worth the time. http://listserv.ipc.org/scripts/wa.exe?A1=ind0807

Hi davef, couple of questions: clarifying costing of direct labor against overhead cost: an operator loading PCB onto the reflow oven is a direct cost, how about the reflow process time of the PCB while travelling inside the reflow, is that an ove

Hello Reflow Masters; I'm using an Omniflo-10E reflow oven. Due to high demands of our production in lead free process, can I use my existing leaded line as an native? Does this option affect the lead contamination of the solder in Pb-Free to go bey
