Nickel Silver Reflow Process - Specifics

Electronics Forum | Fri Mar 01 03:16:01 EST 2013 | grahamcooper22

Solder paste flux formulation can make a difference when soldering to nickel silver...due to the alloy containing metals that oxidise easily like zinc and nickel then the flux has to be able to cope with the surface oxidation when the parts are in th

Wave solder flow over back plate

Electronics Forum | Fri Feb 22 09:41:54 EST 2013 | patrickbruneel

Pete, It would even be better if the wave machine manufacturers would add a feature that allows the wave to drop in rpm when a board passed the wave, and slowly get the wave back to normal rpm when a new board approaches. This would be like a reset

Electronics Forum | Tue Apr 02 13:43:54 EDT 2013 | ericrr

On one of the products uses a QFP (Quad Flat Package)which is not going on straight, maybe 20 pins per 4 sides. sometimes I have to tweak the alignment before the board goes in the oven, this practice can be a bit of a worry if you over tweak it - pa

In a past life I ran F1 systems post placement / pre reflow behind a MyData My12E, so it didn't exactly have to keep up with a speedy chip shooter, but it did pretty well. The AOI would end up being the bottle neck some of the time, but not because

New pcba supplier sent us first article pcbas (SMT, Wave & hand solder operations) that failed our testing due to no-clean flux residues found under ICs and around passive capacitors. Second lot came in and had 100% pass yield, but we still see a cl
