Do solder-mount screws exist?

I have a small circuit board that has no mounting holes but does provide unpopulated test point pads. Is there any option for machine screws or standoffs that I could solder into these for mounting the board?

Surface mount, and reflow solderable stand-offs are available, for low mechanical stress applications.

For example, some SMT products offer spacers, nuts, and snap fasteners in a range of sizes. These do not require plated through holes. The parts come in the reel with removable Kapton patches on top, covering the holes, for vacuum pick-up, so they can be used for pick-and-place assembly as well.

What Others Are Asking

Is PCB testing of all nets after assembly required?

That is my first time asking an assembly house to produce 200 units of a PCB (and not the usual 3 or 5 PCBs). The assembly house came back to me saying that the testability of the board was bad and that they need to have 1.2 mm pads on the bottom side of the PBC for all nets… They require such large pads because beds of nails are a much more economical option than flying probe for 200-400 units since they can do it in-house. Is adding 1.2 mm pad on ALL nets common practice for PCB?

Why are there no BGA chips with triangular tessellation of circular pads?

A triangular tiling would allow π⁄√12 or 90.69% of the footprint to be reserved for the solder balls and the surrounding clearance, while the ubiquitous square tiling only allows π/4 or 78.54% of the footprint to be used. Why are there no BGA chips with triangular tessellation?
