Yes, one should always be concerned about "field failures" because they represent the point at which the product has exceeded its design lifetime with respect to its service conditions. Hybrid microciruit technolgy (HMC) has been around for a long t

So, we've already addressed the tombstoning on these guys by adopting the mfr's (Pana.) recommendations for pad size and spacing. Problem is, we have pretty bad wetting of some of these parts. The rest of the board we use them on looks great, nice

Kurt: Lots of choices, not many of them good, yano. 1 So LPI has taken over the market pretty nearly 100%, but it won't "tent" reliably, because it is not very viscous when applied and drops into the hole. So then, tenting/plugging with LPI is bad
