edge clearance for inline equipment

Electronics Forum | Wed Oct 01 23:40:38 EDT 2003 | bradlanger

I was wondering if anybody could tell me what a good clearance would be for board designs to allow for the use of inline equipment? My company currently runs a batch line but I want to make sure we are designing properly for inline if the need arises

Printing for 0402

SUMMIT 750. My yield is 75%-98%. And they all depend on the pad design, stencil, paste, operator, thermal profile, etc. I have 98% yield on some of our products with good pad design. Process is easy to control. Dreamy

Part clearances in PCB design

Electronics Forum | Mon May 03 21:39:09 EDT 2004 | ACE

Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.
