Ben, I'm not aware of any 'automatic' method to convert PTH footprints to SMT. Typically, many of the components are passives, and there may be a way in your CAD software to change the passives of a common size to a different footprint. That will co

Stephen, This is a board designed for medical apparatus and we're needing to change 3000 placements, it's about 2000 different parts. Some boards have about 90 parts and some have greater amount. Impedence of the board happens to be a great issue

I would appreciate any and all input on selection of ICT/ATE equipment. I'm a CM supplying various PCA's, none of which are designed with test points. I am looking for a robust, user friendly, low cost, low maintence that can be easily adapted for ea

Yeah, James, we've got block repeats set up so we're getting the boards built with just pcb fids, and very accurately. I want to be able to build with block fids, though, in case we have any issues with the panelization. It's happened in the past a

Question: We have an issue right know on a prototype batch with via in the pad on an very small pcb 50x50mm (in a panel of course). The designer has no room to move the vias as they said. The pcb is to packed with components also 8-layers. It is also

MyData has a spreadsheet macro that converts an Excel spreadsheet into the format that the machine can read. First you make up an Excel spreadsheat with the data in this column order: X center, Y center, Rotation (theta), Part number, Reference desig

Even if it is 300 hours, using a conservative estimate of that time being worth $20/hr the machine saved $6,000 in one month. At $6,000/month the ROI is probably no more than 1 year which is good. From what I have seen in this forum over the last c

All posters here are right. My point was you have to design your board to the process. You cannot simply take any connector and change it to Pin and Paste. So much depends on your aperture openings, hole size to pin size, board thickness, number o
