You can buy an awful lot of stencils for $200K but where/how are you going to store all of those stencils? There is a certain $$$ value to all the space it will take to store them. I have been told by a Mycronic salesman that they are working on qu

What part of the country are you located? I know numerous stencil manufacturers in the country that I could refer you to. The one we currently use is Stentech and guarantee next day delivery for basic laser cut stencils. They have always kept their w

Thanks to @davef and @Evtimov for trying to help. It's useful but not exactly the answers I would like to get. I'm going to reformulate my question. I'm writing in mm so that it's more precise: I have a 0.12mm-thick stencil for some 0.4mm-pitch QFN
