"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

You may need slightly longer dwell times and a little more heat in the reflow and wave to ensure proper alloying/wetting. Also consider if you are using a nickel doped and high copper alloy on bare boards in Leaded wave solder bath you will pick up c

Hello, we do have very good results with a 'hot air' repair station, and poor results with a 'IR' repair station, but i have to say that the 'IR' station wasn't designed for leadfree use. Make sure you have a good underside heater, adjustable and

I've used both GPD and Hepco formers. The Hepco radial former is this one: http://www.hepcoblue.com/1800.htm The GPD radial former is this one: http://www.gpd-global.com/text/product/cf9.htm The GPD offers more custom die sets and variations th

It would make sence for Swatch I guess, they probably dont use any component over 0,6 pitch. Didnt swatch just say they would stop production if they didnt get the exemption? Thats probably the main reason they got it, otherwise all this RoHS crap

I want to say one more thing on this; many times RoHS is compared to the CFC elimination. But there is a huge difference between the two for following reasons: In late 80�s scientific evidence became available that CFC�s contributed greatly to the o

I am guessing Theresa is saying when that some SMT parts are soldered (not glued) very close to some PTH parts. So close that they can't effectively mask the SMT parts and have an opening for the PTH part. At the company where I work, we've been tr

Dave, we have the same issue running a new bare board through the oven with no paste. If there is an imcompatibility with our flux would it still manifest itself when there is not flux? Im sure there is some residual flux in the oven all the time. We

Good afternoon everyone, We have a customer that wants to specify "cleaning processes" on a board that typically has a "no clean process". Normally, I would not care, but I have one component on this board for which I question the cleaning process.

To date we are a small niche CM doing prototype and small runs. Any testing we do now is purely functional tests on the pcb ass'ys. In some cases the hardware and software is supplied by the customer, in most cases it's one or the other. We want to e
