How can I connect my small PCB with sensor to the bigger PCB?

My small PCB is mounting a very sensitive fragile sensor on the top surface that has to be wire bonded to the PCB, so I am trying to design a smaller PCB that can be surface mounted to the bigger PCB. How can I get some kind of thin footprint for interconnecting the two PCB boards?

You can just put plated half holes on the edge of the small board and then solder it directly to the large board. This skips having a connector all-together. Many board manufacturers can do this.

What Others Are Asking

What are the black spots in lead-free solder joints on PCB?

I am prototyping a PCB, using Chip Quik’s “SMDSWLF.031, a Sn96.5/ Ag3.0/ Cu0.5 solder with 2.2% no-clean flux. I find that the black spots appears frequently in larger pads on my board. I wonder if it is because I left the soldering iron more time heating the solder and that burnt the flux. What is that black residue? Is that a sign of a bad joint or maybe bad soldering technique?

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?
