First question - do you have a rework station? If so, are you experiencing the same type of failures there? I have successfully used no-clean on uBGA's in the past. 6 mil solder bumps, 10 mil spacing. 88 sites. Are you reusing previously soldered uB

I used to love tweaking. I tweaked and tweaked until I got a master degree in tweaking. But than I had to teach others how to program a board and avoid tweaking. After all it does not go quite conform with ISO and other quality approaches. I investig

Most of the machine suppliers Fuji, Siemens, Universal and Panasonic did regret that they were building glue machines. Applying adhesive compared to placing a component looks so simple, but it is not and the defect rate is higher than placing 1206 c

No N2. We could not fix a benefit for N2 in our minds. Just fold the excess bag material over to expell most air and then seal the bag. [Have you assessed the benefit of N2?] F Monette can tell you stories about little versus more pressure. If he

Imm silver holds-up to multiple thermal cycles very well. The things, we guess, are happening to make imm silver tough to solder after heating and sitting are: * Oxidation of the silver. * Reduction of the co-deposited organic anti-tarnish [used in

Hi Folks, This is a totally speculative, if not cheeky post. I know very little about electronics, but I think you guys do. I have a problem with my car radio, that I'd really like to solve, as I cannot buy a new one where I live (Brazil), and I th

Cannot comment on "best buy". You'll have to determine what the better machine is for your application and duration of planned use. I suggest taking a field trip to each vendor's nearest demo facility with a few of your most hi-tech boards and stenci
