That does sound like a great deal Tsvetan. Can you share any information about who/where exactly you purchased the machines, and which printer/reflow you have? I do have friends and colleagues in China that could ease the process if anything is comin

We are a local enterprise with limited resources, just like you described, so hope this experience sharing helps : we place a production Visual Mechanical Inspection (VMI) inspector at the end of each Reflow Oven area, complete with magnify scope 30

I would love to use my old zevatech with a large nozzle (qfp) to pick kapton masking dots and place them on a board. I am getting some 'thicker' kapton dots to test, and need to find a way to present them, might be a trick but worth a try. Has anyon

Thanks for the comment regarding the CPH. In fact, the benchtop oven we have takes 7 minutes to complete a batch soldering, so you can imagine that our production volume will not be very high. We can parallelize PCB assembly and oven phase. But defi

@Alexei Shkolnik Ah, I hope this doesn't become a problem. But if it does perhaps we can redesign the whole system? Push the components with a pusher that's connected from above rather than pulled by a magnet below. Perhaps the pusher can still clim

I just like to ask if somebody else experienced a similar problem: We press rigid flex PCBs at 356°F (180°C). The buffer layer construction is: Plate PET PVC PET PCB etc So far there were never any problems. But suddenly the PVC becomes very blac
