We had a similar problem with lead-free through-hole components. We baked those baords to remove the residual moisture and everything went to 100% pass - defect was gone. Couldnt hurt to try a sample run while you decide if the PCB holes need to be

ni, I had similar problem too.I bake PCB in SW mashine - about 8h ,T=90 C.Problem is in the base material of PCB - there are moisture in the material.After my complaint to PCB factory , they change material and the problem disappear.

Questions are: * Do these pads take solder? How well? * Have you stripped the gold and evaluated the condition of the nickel?

Glastic is cheaper than the custom composite materials normally used for pallets, but the few I have had fabbed started to degrade pretty quickly. Some pallet material is rated at 260 C continuous / 360 Max where the best Glastic I could find is rate

Questions are: * Do these boards meet IPC-A-600? * What does your supplier say is the source of this color variation? * What steps is your supplier taking to make the boards more acceptable?

Let me know how you make out with these. We are looking in to building some boards with them as well. Don't touch the dome with the nozzle when you pick the part!
