Trying to get a CS400D working. We are programming a 10up board and are trying to set permanent offsets in the program and we cannot get them to read in. Any help?

Nippy, This is exactly what we are seeing. The exessive pads are all on one side of the board. This is a 10 up panel 5x2. All of the QFP's on one side on the panel are not releasing or are not gasketing and causing bridging. So the defects are rangi

Remember this is a 30 layer PCB. If it is built in a multi up panel, there is lots of room for error. Lets say there are 10 circuits per panel. Say you have a 10% scrap rate that happens randomly within the 10 up panel of circuits. Apply this 10%

I have a mixed technology PCB that has SMT all on bottom, TH parts on both sides (Yes, I realize that's bad. Can't be avoided.) We have designed a 10-up panel, 2 x 5 array. There are 50 leads per bd, 500 per panel. How much time is reasonable to a

Guys, My problem is that I have a 10 up panel and I have to use a selective pallet to run it thru the wave process due to SMT on bottomside. However the yields are very poor. We have done everything to improve them with some good improvements along

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture

If I have more than 1 X-out on a panel I set it aside for use as a setup piece or for training. If that's all we have and I need a couple more boards to meet an order I'll inspect the bare panel myself and go from there. We get a great price on board

We process a double-side reflow board (10 ups). Chips and IC's on the bottom side while chips, IC's plus thru-hole connectors and IC sockets on top side (bottom side first then top side reflow). In the past, we were not encountering any soldering pro

Hi folks, thanks for all the tips. We have run our first batch of these flexi boards now. I had the PCB suppliers make me some 1.6mm FR4 carriers to lay the boards on to carry them through the process. (1 flat & 1 with cutouts for the second side)
