How do I find a PCB schematics for a device?

We are new brand of medical device. We are doing a device development recently. How can we find PCB schematics for reference?

Schematics don’t do you much good on today’s high-tech electronics. Most high-tech electronics nowadays use custom chips or FPGAs so a schematic that shows all the signals going in and out of a magic proprietary chip won’t do you any good.

A lot of lower-tech components that perhaps use discrete parts, relays, discrete resistors, etc. do have schematics on the inside of the case or available online.

What Others Are Asking

How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

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?
