Marcos ,, We do place BGA in our HS180 but not that often , as we do run into some problems sometimes . We found out the best way for us ,, to turn outline on , and also paint the outside of the BGA with white pen and you won`t have any problems .

This forum is becoming a salesmans dream! I agree with the first guy, check the archives as there is alot of information about cleaning and media. Our company uses a Kerry SC1000 machine very good process but mechanically we have had problems with t

Before changing solder pastes or jumping through too many hoops, check the melting point of the 100 Sn (pure tin) connection. According to Kester, the melting point of 100Sn solder paste is 232 degrees C. If you do not reach that temperature, you wi

There is not enough time in the day to reliably hand solder these connections. Go buy yourself a solder fountain and spare yourself and your company the misery. Check the fine SMTnet Archives for sources of supply. Everything has a price. A solde

Our co. is thinking of moving to smocks, but we aren't there yet. However, I can understand why we might want to. Have you ever seen the static buildup on a wool sweater or a polar fleece vest after rubbing against a chair all day in a cold dry pra

What happened to good ol' 30 ga. hook up wire? I used to be a whiz with a wire wrap gun. I've even hand soldered wires to a 240 pin QFP (the Engineer was too cheap to buy a $80 socket). Just what are they teaching in these edifices of matriculation

Aw Dave - you guys are so fashionable, are the dark green and red combos seasonal? caramel brown like a Pale Ale? I once heard that the green was chosen because it gives the best color contrast for white silk screens. As for color reflecting or abs
