If you have surface mount on the bottom, you can place openings between any thru-hole parts that constantly short. Your adhesive is a natural solder block!

Wow, that must be a lot of HASL to reflow and block a thru-hole. Sounds like your board house changed their process. Contact your board house about this. Change your incoming spec to look for this a well.

Got a picture? Most times I hear this situation it turns out to be a bent leg on a thru-hole transistor that didn't go through the board.

Vias are thru hole, pcb is two sided, bottom copper is 2 sq inches, vias are 0.6mm diameter. thanks,

Sorry new to this... Question: will I have any problem soldering a resistor network with SAC305 coated leads using a normal leaded wave process besides the normal board thickness issues Thx

SAC coated leads on certain components require more dwell time. If you find that you have top-side wetting issues, slow the conveyor down a bit or increase your wave height, or, a combination of the 2.

Component cost or placement cost? Hand placed or machine placed? If all machine placed, how big of a board? Panelized or not? Any thru-hole? Any shields?

I'm looking for placment cost on machine placed SMT parts. Circuit is 2"x2" on a 6up pallet array. Also has 3 hand placed thru hole caps.

How about your bare pcb handling? do you stuff smd component prior hand soldering? you can try to bake the pcb and then see if this problem still exist.

Option 5. If you have thru-holes as Bert mentioned, and if it is plated even better, you still have a fairly good chance to proceed. As long as you know the exact coordinates. But this can be tweaked afterwords, the important thing is that you got th
