Slaine, our intuition is the same as yours [that 100Sn should dissolve the copper faster than other solders]. Bob Gilbert's FCT data shows otherwise. Look here: http://www.fctassembly.com/newsltr/2004/0804/Aug04.htm

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

Jay, What are your board sizes? What is the maximum size that you envision reflowing? 10-50 boards a week . . . is that in a single run or broken down into a few boards a day/hour? Do you have a high mix or is it a single product? Are the boards
