As I stated, the reply was direct from Indium, (thanks to Rich Brooks). The information regarding cool down rates should come from your paste supplier; not an oven supplier; not a generic article on lead free. I just went through the data sheets from

RF pcb is all gold with no typical land patterns and multiple surface mount components sharing the same pad. IPC-610-B doesn't speak to inspection criteria. The problems I'm seeing are, insufficient solder, skewed components. Some of the pads have

| I am profiling a BGA for the first time and I am seeing temperature flucuations on the ramp and cool down from the thermocouple I have placed through the pcb and under the component. I am using a 5 zone convection oven.Any suggestions on the plobl

First, responding to your question � Several things on copper dissolution in solder are: * A 50um copper wire will dissolve in 60Sn / 40Pb solder at: - 200�C solder in 55 seconds; - 250�C solder in 20 seconds; - 300�C solder in 5 seconds; - 350�C so

From Indium Guru, (Hi Rich). "Ramp can be taken anywhere.... but mainly you want to look at the ramp when the flux is doing it's job. For the Indium paste, I would set a ramp rate of 100 to 200 (or 120 to 210).. somewhwere in that range should provi

Chris, you need to get out more. I haven't seen a DOS only MPM in many years. Most MPMs do have that new fangled Windows on em'. Shoot, even seen one of them fancy flat screens on one (in the rich parts of the neighborhood)! Seth, what type and y

If this is same TennRich Type B [ http://www.tennrich.com/trtw/TR_PI_Prod_Info.php?pid=2 ] that is an EMI gasket, it needs to be glued with a conductive adhesive. It has the same thermal capability as a Snickers Bar, about 90*C top end.
