Many people use the same spacing [and pad designs] as they use for primary side SMT. We don�t. DOWN STREAM SMT-TO-SMT SPACING: In addition to proper orientation, components cannot be immediately upstream of terminations that are to be soldered or b

We had two 51 space trays. One was modified by machine shop to hold two waffle trays. We bought a 31 space tray thinking it would hold one tray, it doesn't. We modified it to hold one tray. We than learned, from tech support, that a 31 space base sho

We considered direct marking already John. It's not very practical for us to do that. We need to put labels on components as well as boards. A laser or inkjet would cause us to have to change too many things in our processes. We'd still need to do la

Hi Simon, The main reason that it would probably be removed would be do to lack of clearance for a soldermask dam from pad to pad. typically if the clearance from pad to pad is under .008 the solder mask dam would be removed. Min recomended dam siz

Hi, that's how it works: 1. Zoom to the object you want to start with. 2. Click S to center to the object. Depending on the zoom you can center to pad, line, corner.... 3. Click Z(this zeroes your Relative coordinates). If you click Ctrl+z(this ze

I think you needed an IPC Class 3 annular ring because for very dense designs, the smaller the annular ring the better, as less space is taken by the pad or via and more space can be dedicated to routing the traces in highly populated areas of the bo

Please define "worst case for feeder sizes". Quantity? Arrangement? wasted feeder space?
