Hi LWEI, This is not a permanent fix for the problem. We have had similar experiences with double sided boards. As a fix, we have applied water soluble solder mask to the edges of the component. This holds the component adequately for second side pr

we have used board mask that we let dry. It's tricky to get it flat with no spikes, but after a few tries you'll get it. I like the guys recommendation to try paste and let it dry. we have that problem when the operators do not clean the stencil p

Hi, I can give you a few steps. 1. The solder paste. Take the profile that manifacturer gives for the paste. 2. Use termocouple to measure the tempereture. Put PCB and measure the temperature in equal terms. 3. Compare your profile to manifacturers

Thanks all. We are using no clean, so the boards are not washed. That would eliminate the trapped water issue. We would check the PCB after dismounting the BGA, and the short would not be found. When we place another BGA on the board, the board w

Hi, No Major issue using lead-free plated components in tin-lead as long as Sn/Bi is not the finish. I think some customer might be worried about low melting phase. More voiding may be seen in case of ceramic capacitors used with tin-lead. It is
