What kind of parts are on the bottom? Small passives are very unlikely (won't unless other abnormal factors come into play) to fall off when reflowed a second time regardless of temperature differential. There is a simple weight/soldered surface ar

Hi Rob, Don't feel sorry I like these discussions make us think more thorough. This is the supporting scientific paper they used in support of the exemption request. Effects of lead on tin whisker elimination By Wan Zhang and Felix Schwager. http:

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema
