BADASS

Just out of curiosity, do both new and old style asic chips go on with the same technique? do you have to vary it between the two?

Thank you! These things are definitely doing well, and once I get this other jally running (maybe) I will see about taking the two of them to 8 chips. Which will basically give me a single/60. :-)

As for the chips: I have had issues with the old style chips, specifically I was shorting one of them because heating from the top caused the solder holding the chip to the board to go molten. That's a big problem; it implies that one needs to use a reflow oven instead of a rework gun since the chip and carrier do not conduct the heat to the pads. However I am also finding out that leaving the board at 375f on the pre-heat board is enough to make the components almost "jiggly" so that even a small amount of heat can blow a component off the board. It might be possible to preheat the board to hell, then use something like 375c air to melt the balls. Maybe.
