Some customers ask us whether metal dome can bear high temperature? Whether it will have deformations or its force will be changed?
The material of metal dome is stainless steel, in general, the operating temperature of metal dome is -40-100 degrees, so if the operating temperature close to or over 100 degrees, there are definitely having changes for metal domes, including force and resistance. some customers place metal domes on PCB and FPC, then through SMT soldering, as we know the temperature of SMT process is very high, so the performances must be definitely affected and changed, although we do not do this test. So normally we suggest customers to place domes after SMT process.
Who has this issues, welcome to contact us, we can discuss together. Best Technology are engaged in providing a variety of solutions for customers.
