I'd like to add something about the ECD product. During a past work term (I'm a a co-op student) in an SMA plant, I worked extensively with the Super MOLE Gold in developing the reflow profiles for high-mix, low-volume production. I was 'married' t

We find that the raw BGA's pad sheared surface has the SnPb solder at various Z heights whereas the assembled BGAs pad leave a smooth layer of SnPb along the pad. Like to understand the cause for the difference. Who could guess? Solder joint streng

>>>>Dave, The BGA substrate surface finish is NiAu, while the PCBA pad surface is HASL. The solder ball composition is SnPb 63/37 and the solder paste used on the PCBA is also the same but with 2% Silver.>>> Dave, sorry I don't have the picture with

| Anyone have any experience with ECD's Waverider/MOLE profiling equipment? If so, were they positive experiences? | I use ECD's mole for profiling in the wave and a KIC for profiling in reflow. I like the KIC a whole lot better for a couple of re
