Thanks,
I did found some Chinese companies, the rough price per sq inch is 0.5$ for 10 layer and 0.3$ for 6 layer PCB. On a large (50sq inch) PCB the difference is 10$. It can probably get cheaper w/negotiation for very high volume, but I agree, 6layer can turn out to be too noisy.
Hi,
Does anyone have an idea what is the (very) high volume (100k+) price difference between six layer (4Sig, 2planes) vs 10 layer (6sig, 4 planes). Or, any web based calculator (haven't had luck locating one) for high violume PCB. I am inclined to try with 6layer, but then the traces must be...
Hi,
When creating PCB part, I was able to measure pad-to-pad distance to verify my component. Although the pads are not on regular grid, the cursor would snap to pad center when clicked near by. Somehow, I lost that feature, I think I pressed some shortcut inadvertedly. How to regain it, anyone...
Hi,
Is there such thing as 7-segment LED display with integrated driver, prefferably I2C controlled one? I would like to avoid separate driver due to cost/space. That is, it would be nice to have display with Power, GND and Interface lines only :)
Thanks,

Hi,
what is the easiest way to create PCB pattern for 1434 pin BGA (called FCBGA7) part?
Wizzard does not help much, the pin pattern is odd, not all pins are in rectangular grid. I have a list of coordinates (wrt center of component) in pdf, if I make it in Excell, can I...
best circuit pcb designing software
Thanks, I am also inclined to take it. As for autorouter, I am yet to see the "perfect" one. Even those boards that come with the demo package (and are presumably autorouted) are not that great, there is a room for improvement. As ususal, it is best to place...
bst pcb software
Hi,
I am looking into Sch/PCB SW, and we narrowed down choice between Pulsonix and Altium Designer. I checked both (still evaluating) and am satisfied, so the tech side (UI, Options etc) is not a decisive issue. Can someone advise what is better choice, having in mind tech...
