We currently screen print glue for our bottom side components. We are looking to get the bottom side of one our boards screened with a solder resist (to cover mounting holes, etc, for the wave-soldering process). This would create an uneven surface

I'm also in the "Don't score it" camp. Routed breakaways are much better. If your wave solder process has decent control on the wave height, you shouldn't worry about flooding the boards. The fine pitch consideration for panelizing - Since you norm

Place your components directly on the PCB without using solder paste,unless your using high temp. solder spheres then you should use paste. If eutectic solder spheres are used try fluxing the BGA area and attach it directly to the board. This will re
