I'm confused. A paste Supplier suggested to turn off nitrogen during reflow because it is one source of voiding of bga solder joints...is this true? regards, Dreamy

Why you do not try by yourself ? Run some BGA reflow with and without N2 then X-ray the solder joints. Regards GS

Hi Grant, We used to use Quicher automatic screw feeders - that basically present the screw for pick up to the driver - they worked very well. Let me know if you want any further info on this type of feeder as they may still be kicking around her

Grant---Contact the Pemserter folks---They have a system called "screwstick" (or "stick screw") which may work for your project. Good luck. Nick H.

Where exactly does specific gravity help convert volume si units to imperial units? How about Google. search for volume converter or unit converter...

because Kg is not a volume unit but a mass unit... (One would think that this sort of stuff is common knowledge in a tech industry... apparantly not...) Base (former science teacher... really!)

Hi, Outside the US, Kg is more commonly known as Kilograms, and is a weight. I assumed thats what he was talking about. Regards, Grant
