Questions you would ask if someone said they had a 3D printer for professional multi-layer PCBs?

Electronics Forum | Wed Feb 25 09:09:24 EST 2015 | spoiltforchoice

Are we talking a professional device that takes something like the Squink/Voltare/EX1 projects on Kickstarter and delivers something that could be confidently used commerically? Would it be strictly a prototyping tool or would it also be suited to lo

Hi, I've bought a camera for video inspection ,Metcal VPI 1000 model. Price was reasonable. Unfortunately the light and video control box was missing. Now the light I can easily fix but I have no idea about the video part, I do not know the tasks for

Thanks for the feedback and the confirmation that it is, in fact, a bug. I have trained my operators to always use file Save at the end of the day (up to a network drive) & then I have an external program that archives the daily setup back into our r

Hi, I agree that the existing systems sometimes difficult to implement. Also, as a large system so its maneuverability is low in spite of all the beautiful tools. Usually if you need something you do not find anything there. We, as a software compan

I've put down a SOT223, close enough to your 3pin transistor, in the same situation you have. The large pin was to be soldered on a large exposed ground plane in the corner of a board, over 2"x2" exposed area. We left the paste file as is, so where

I have a customer who is rather inexperienced, and asking us for a solution for them. They have a circuit board that's roughly two inches long by 1/2" wide or so, with component placements on one end of the board. The other end has a trace that I s
