We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

Thank you very much for your informative and helpful reply. I have a few more questions:) 1- So for the case 1: should I apply the glue to the PCB with the same method as I apply solder paste? (with screen printer and squeegee). If so, I would guess

I'm looking for some guidance here and would appreciate input from some seasoned professionals. I am the Op. Mgr. for a medium sized electronics contract manufacture, but my background is almost exclusively in the machine tool industry and I would li

We'd like to help you, but we don't have a clue of what you're talking about. * Which 'heatseal' machine are you using? Is that a reflow soldering machine? See, we think of a heatsealing machine as one that bond the two sides of a plastic bag togethe

Your kinda vague on your description, How many components per hour, how many circuits per a day, week, month? what kinds and size of parts.? For a PNP setup for smt boards you will need a stencil printer(possibly manual or full auto like a DEK, 1 o

Here's two ideas fro the fine SMTnet Archives: * On the bare board, during design / layout, the basic shape of the jumper is a 125 thou disc of copper [that of course is eventually covered with whatever solderability preservative we use on the board]

If 3-5% of the attempted parts placed are dropped, you have a serious problem...that's 1 part dropped for every 20 or 30 placements. Does it mean that it drops the part in the scrap bin and then successfully places the same part or would the board co

I would assume every EMS company runs into this issue on a daily basis. Before we get to how a machine handles it, I would recomend setting up an acceptance criteria with your board supplier... if you plan on accepting them at all. (ex. No more than

We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit

Sounds like you have tried everything I can think of as far as hardware is concerned. One thing that sounds suspicious to me if the error "Failed to create empty document". I have only seen that error when my MMI software got corrupted in the process
