We are planning to purchase a stencil for our LED boards. This will be my first stencil purchase so I don't have much idea about a good or bad one.
The inquiries I received typically suggest two materials: Phosphor Bronze or Steel. Steel ones are charged at 100$+VAT, while Phosphor bronze are about 65$+VAT.
The product is a high volume one, so the stencil will be used a lot. Also, per the info given to me, the holes on phosphor bronze are acid etched, while steel is laser cut, so there may be some roughness on phosphor one. We are not making a space shuttle PCB though, just some 2835 LEDs, so I guess this should be OK (again, just a guess)
Question is: what are the advantages of steel over phosphor bronze? Is the price worth the cons: durability and quality-wise, or is it just a trap? Should I have any concerns about end product quality if I buy the cheaper option?
