What type of silkscreen ink is used in PCB manufacturing?

Sometimes, my PCB supplier mentions about silkscreen ink when it comes to logo printing. I am curious about the types and features of different inks.
  • pcb manufacturing

There were 2 different inks used in practice-Solder mask and legend ink.

The solder mask is used to cover the entire PCB board and is usually green, but it can be almost any color. It is UV activated, so the areas that are masked can be scrubbed off while the UV- exposed areas are permanent.

The legend is not necessary, but nice to have for placing the components later. Legend ink is an epoxy with a very long drying time. Cure it in an oven to quicken the drying time.

How can I mount a pulse oximeter on the surface of PCB without putting too much stress?

The PCB has a pulse oximeter mounted on the surface, and it’s tolerance is 0.6mm. The problem is the pulse oximeter needs to touch the bottom case at all times. How to best mount the PCB in the case without putting too much stress on the pulse oximeter? Will screws with flexible washers be all right? Sadly separating pulse oximeter from main PCB is not an option.
