Thank you for fast reply.
Well, I was hoping that there was a "cheap" and good machine All In One..
So, taking apart the AIO ideia. What is the "best" or "modest" stencil printer + PNP machine + Reflow Oven? Or the best brands to looking at?
I found TVM802A+ Reflow T962A+Printer YX3040 for 4000USD. Is a good set?
I do manual stencil printing, and it works pretty well. I make my own stencils by etching .003" brass shim stock, using essentially the same process as for a double-sided PC board. I use masking tape as the hinge for an unsupported stencil.
I did make up a board holder fixture. It has an aluminum plate with a 1" grid of 10-32 tapped holes. There are 4 bars that have a .060" deep step on the edge and slots where screws clamp them in place on the plate. This supports the board by the edges, even when it has parts on the back side. (Most of my boards have parts on both sides.) I visually align the stencil to the board, and tape the stencil in place. Then, I spread the paste with a thick brass squeegee.
This works amazingly easily. I have done well over 1000 boards with this system. So, if you are looking at relatively small volumes, you don't need an expensive stencil printer.
I do reflow in a GE toaster oven! I have a thermocouple ramp & soak temperature controller. I poke the thermocouple into one of the boards' through holes. I often do up to 6 small boards at a time in that oven.
I have a used Philips CSM84 P&P machine, which is a very flexible and robust "old school" machine.
