Hello Joe, PCB size 6" *6" is larger board. Resistors and LEDs are easy to do assembly. I think you can ask Beijing Glichn, from PCB stencil printer, SMT reflow oven and LED pick and place machine, they can give some suggestion. The investment is de

The unique heat on the PCB is the big advantage and you also can´t exceed the temperature of the boiling point of your medium (we use a 240°C Galden). So small components are not "overheated" until the bigger ones like DPAKS are soldered. You also ne

You can try my package PCB Synergy. http://members.iinet.net.au/~sarason/ It can panelise many of the data formats it supports, but not all of them. If you mean panelise the PCB for manufacturing the board, then there are literally heaps of gerber

I believe there was a software issue as well; Initially installed software (4.03) replacing existing 2.12. After that it got past the "Stack Overflow" and displayed the expected error for incorrect addressing on PCAD12... BTW solution to "vision boa

We check the resistors to value check them. We are using resistors that are not marked in any way shape or form. We also hand build everything so it is very possible to have our operators place the wrong part in the wrong spot. From a time point of v

By the way how are PCB's made (briefly)? During my radio apprenticeship in the 70's I made PCB via the screen printing method, The other method for say one off or small volume is the photo-etch. Is there a third high tech method, or just a updated

Hi, Regarding to thermocouple placement, you should use a precision thin drill. Drill through the bottom of the board to the top as follows: One hole in the center of the part, preferably into one of the center balls, if available. One hole into the
