We treat all our alloys with measured Phos additions. SAC alloys treated with Phos WILL/DO dross approximately half the amount of 63/37. Most Solder companies will not tell you this as they wish you to use more Solder. We are a Nitrogen Cast Solder p

Dross formation rates for SnCu and SAC are roughly 2.5 times the rate for SnPb (Hwang et al., 2004) Methods for reducing dross are: * Lower pot temperature * Run pump speed slower and only when soldering * Check solder contaminants to BS219, ASTM

There is no local support for Juki or Samsung in Chicago. If I pay $5000 Samsung will be able to monitor everything remotely. I am still unsure of the life of a pick and place machine. I have seen some Universals get to 50,000. Not sure about Ju

I have over 10 years experience in aerospace materials, part of which was involved with vacuum casting inert propellant formulations. These propellants are in the range of 80 - 90% solids loaded with viscosities of 15 kP. I'm not sure where I could

Does anyone have any experience with solder paste recovery? Specifically, partially emptied solder paste tubes. We are currently looking into ways to reduce and potentially eliminate solder paste waste. One of the largest contributors is partially

what are these kids doing in the dark with band-aids anyway? I'll bet you could get the same effect with Kapton tape (maybe yellow light?) Seriously, I use the IIT proframe Dave mentions down to 25 mil but have gone back to a permanently mounted foil

You say "I have seen you make false accusations of name changing and false postings against some reps quite irresponsibly. In conversations before with others offline your accusations have forced a number of good reps to skip providing input simply b

If you wanted to use ultrasonics to wash an customer's assembly, and you'd had poor success doing it in the past, would you consider it reasonable for the customer to request that YOU provide cross-sectional image analysis of the first batch of new p
