Dave: You should see a solder smudge on the gold plating where the ball was attached, if there is (was) solder reflow during either the (1) BGA fabrication, (2) your BGA attach, and / or (3) your BGA removal. You rework will not remove the solder

| | While inspecting incoming PCBs we detected around all plated-through-holes (only there and all in the same place) some halfmoonshaped light rings that match obviously only with the pink ring symptom shown in the IPC-A-600 chapter 2.5.2.. That wou

Now don't everyone jump on this at once, but it seems time for me to send out copies of my not even close to being dated copy of an article about HASL. Though it was published in 1992, in Printed Circuit Fabrication Magazine, and it got rave reviews

We are using .040" diameter fiducials (global and local) on our boards. They are solder covered and HASL. I get batches of boards where the p&p vision system has trouble reading the fiducial. The fiducial looks dark on the screen. The board vendo

We have mixed to negative feelings about Omikron, but I beileve it is due to problems with the board fabricator rather than the process itself. When done properly, our Omikron boards have had very good solderability. However, we have had several ru
