Today, I have just finished evaluating Kester's EM907 (SAC305)lead free solder paste and found that for our applications it performs as expected. End result that I am encouraged with the results that we got. The equipment that I used: An SMT2020 to

Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t

Hi Jay, please let us know your inputs from the seminar regarding SN100 Nihon solder from FCT. This solder seems to have a higher melting temp of 221C. It prints well and visually looks similar to SAC alloy. Have no reliabilty data though. Jay

Well if I thought using wood tools was a good idea I would not have posted the question. Since the flash point of paper is 451F I would assum wood would be close? I guess I should have asked does anyone know of any tools kits or come up with there ow

Yeah, made from Durostone or Delmat would be perfect. Try buying some pieces and have them machined into tools or DIY. This is the same material that solder pallets are made from. http://www.boedeker.com/durost_p.htm http://www.polymerplastics.com/

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel
