Ed: Couple things to observe on the pinhole issue. 1. At 4.5 ft/min., wetting up through the barrel may not be happening with a 190 topside board temperature. 2. Another possibility is if you have top side through hole components that are setting flush to the board, the only place to outgas is through the bottom side, hence, a pinhole or void. If this is the case, you may want to use a slotted spacer on the top side of the component. If this is the problem, the spacer will fix the problem. 3. It could be the quality of the barrel itself and you are getting outgassing from the board. EEEHHH,,, I am not sure about this one ,,, there are some other things that come into play here, like A. barrel quality, B. laminate construction, C. moisture in the board (however you are baking, but this time of year maybe not baking long enough). Hope this helps Ed Gaven.
