We are looking into what equipment would be necessary assemble circuit boards. We will most likely purchase a circuit board and use a pick and place machine to populate the board, and then send through a reflow oven. Then inspect the boards and ass

OH MY GOD!! Finally it's becoming public knowledge here on the streets. YES germanium is in this material. As much as these guys and ALPHA METALS wanted to keep these things secret, anyone with a halfway competent lab would quicky find out why all of

Amen to that Patrick. I am from a traditional Engineering background myself - they never taught wave solder in school. My curriculum was mostly theory and labs. When I got out, I read all the soldering books available at the time and also watched s

No, I don't work for Suntech (me company name is different but close, it much have been misspelled:-)) and the company isn't exactly a trace lab, However, that wasn't the point why I �jumped in�. Defining a problem as �solderability� is too generic.

No arguments there. I 100% agree that quality engineers can and do solve a lot of problems on the spot. I've nevern said "run an analysis as soon as you get a problem". The whole nine yard started with a solderability problem. In my previous product

Dear Hegemon, I'm very grateful for your help. There is one more thing that I'd like to discuss with you. I'd like to know if there is any "verification board" or something like that to check if you really did a good job. At the company where I wo

Thanks for the response guys! The parts are being sent to a local lab as we speak. I'll let you know the results when I get them. I am not sure the purpose of the copper band, but the black around the band is just shadowing from how I took the pi

Thank you for support. As i promised you, I am coming back with the results. The SM used was Probimer 77 with Kester 979 flux. The supplier says that there is an incompatibility and we have changed the flux with IF2009M. Same problem! They have chan

Early on when we started looking at BGAs we tried dipping. We've done it in production for a couple decades with flipchips. Dip fluxing BGAs worked fine in the lab but we ended up starting production with screen printed flux for cycle time reasons.

Hi I work for Asymtek, so you know my affiliation up front. I just want to mention that Asymtek makes conformal coatings sytems from Bench tops to full auto in- line systems. We have applications labs in the USA and around the world to help companie
