Greetings, I am pretty new to SMT production, and have learned much from this forum. I am getting ready to build a CCA with many 0402 parts that are really close together. I consider these fine pitch. The board also has two QFPS, so my stencil design

Alot of the companies out there use Standards developed internally, centered around there paste, equipment, and reflow processes. Normally you will see either 5mil or 6mil stencils used for everything in house with the exceptions of specific boards.(

Answer on point 2 - I understand you send him gerbers of single PCB (?). In most cases you have panelized PCBs so to avoid problems with stencil first you should order PCBs and ASK your PCB supplier to send you back his gerbers of panel. There are so

For most applications, a nice square [or rectangle] pad works just fine. Assemblers ship boat loads of boards with these every day. It's reasonable for tight decoupling capacitor requirement applications to use round or radiused pads for components

I've never seen successful printing with a step as deep as you seem to be saying. The keep out would have to be jigundous!!!! SMTnet Technical Library: https://smtnet.com/library/files/upload/Step-Stencils-laserjob.pdf I'd guess * Maximum step
