Patrick, Have you seen Al Gore's documentary on Global Warming, "The Inconvenient Truth?" It was okay, but I didn't like how Gore got political in a few scenes by slamming the current administration's environmental policies (or lack thereof...c'mo

Some production problems we've faced: 1) Delamination; 2) Reflow fixture distortion; 3) Obsolete parts; 4) Failure of blower motor bearings in older reflow ovens; 5) Poor toe fillets with miniSOTs on thicker PCB's; 6) Lack of updated component data s

We are an OEM and we were about 75% converted to lead free. Very few of our customers showed any interest in ROHS compliant products and none of our competitors were doing it either. We had a few field failures that may have been related to the hig

Your failure rate should be as good or better than any other leaded part on your board. Have you done a reflow profile on this board. We typically sacrifice a board and drill a hole from the bottom and then imbed a probe under the part to get the tem

I'm about to begin a job for a customer placing a couple of lead free BGA's/FPGA's on an assembly that doesn't need to be RoHS compatible. So...my question is...should I process this assembly with lead-free solder paste, to accomodate the lead-free

1) run the BGA side first. set the bottom temp lower (if your reflow oven have top and bottom temp setting) for connector side while doing your 2nd reflow. 2) run the BGA side first with your normal leadfree paste, and run the connector side with low

I doubt it's the board house. Check the Laminate being used. When you find out that the laminate is IS410, search the forum for time and location for the next "RoHs Compliant PCB Delamination Support Group" Some of the locations are hard to find but

You may need slightly longer dwell times and a little more heat in the reflow and wave to ensure proper alloying/wetting. Also consider if you are using a nickel doped and high copper alloy on bare boards in Leaded wave solder bath you will pick up c

I use a Liberty Bandit brand hot air rework station and have placed 676 ball BGA's with very few problems. All of our products are now RoHs. They have good product support and easy to use directions. I think this unit runs about 15,000 or so. Good lu

Hello All, I am working with a Mid Sized PCBA Manufacturer as a process Engineer. We have recently moved 1 of our customers to RoHS(Silver Immersion) boards. We are seeing a lagre number of issues Blowholes, allignment issues, board quality etc. We
