Put a machined guard around the pulse oximeter to keep the surface from it at about 0.2-0.3 (if it is and SMD part soldering height tolerance is about 0.2mm) and then simply screw down the resulting assembly.
Otherwise use weak springs to push the p.o. against the case, need to know the allowed stress on the body for that.

Depois de fazer esforços em um período, Finalmente terminei meu design de PCB. O próximo passo é liberá-los para a fábrica para produção. Para ser honesto, Não quero nenhum erro no meu arquivo que possa interromper o processo de produção. Então, em quais pontos devo prestar atenção ao verificar meu design?
I send my PCB design to manufacturer for prototype, but they send back deviated PCB samples with additional zig-zag. Why are there zig-zag lines on it? Reducing interference?
My PCB manufacturer just informed me that he is facing PCB warpage issue in my simple, single sided, copper poured PCB. He says to avoid this issue he suggests to add a dummy copper patch by keeping 3mm copper clearance from all sides. Can somebody tell me what leads to this issue and what are possible solutions to this problem ?
