Hi, Looking to generate some discussion on the merits of using the ERSA Versaflow inline selective soldering machine as a real alternative to wave soldering in sub 100 batch size low volume high mix production PCBA Production. I work for a tier 1 C

Hi, No we did not look at Pillerhouse, We were not particular fond of "moving the product" principle to selective (i.e using a gripper over a static nozzle), as often this requires pallets, and our sister plant had already completed testing which a

From our notes, the following is a series of snips from: "Copper Dissolution in Tin" LJ Turbini, PhD, adjunct faculty member, University of Toronto, Materials Science and Engineering, SMT 2/07 As the solder becomes molten, copper from the board diff

OK. You used a thermometer to to check your recipe. How do know that the temperatures that you selected are correct? Your solder balls indicates that it's possible that the temperatures that you selected might not be correct. Without belaboring an

Hi you need to dip long enough for the temperature of the part being soldered to reach about 20 degrees above liquidus of the solder. For the small parts we dip solder we had Sn62 and SAC387 baths set to 250 degrees and this seems to work best for us

Interesting, Gary. Try this: 1 Assess candidate solders by reviewing J-STD-006 (http://canfieldmetals.com/j-std006.htm) to determine solder formulations that have liquidous temperatures in the desired range. 2 Request recommended profiles from supp

Key Issue: Will this machine solder your boards? You never know until you solder one. Any other avenues of analysis involve substantial risk. Flux Selection * High or low solids * VOC or VOC-free Solder Alloy * If using lead-free, avoid stainles
