Hi, I have a test pcb that came with my Yamaha YM84S machine. The board contains land patterns, fiducials, etc. The pyrpose of the board is to test the placement and vision systems in the machine. Does anyone provide the technical drawing of the bo

Yes, using an illuminated magnifing glass helps. How well your board fixuring is on the table will effect print alignment on other boards loaded. 0.5mm & 0.4mm will require very good fixuring, like you can get with tooling pins if the board has non-p

MPM uses a one-print-Mylar system, as do other printer mfrs. In this system there is a Mylar sheet attached to a frame that is secured over the printer table with the board on it. You print onto the Mylar. The table X-Y-theta manual adjustments are u

You are correct in understanding that the vision system comes into play for subsequent boards- to align them. Yes- if you missalign the first board and set the cameras to that board, all subsequet boards will not be aligned. Mylar is a thin polyester

You should be able to get a one-print Mylar frame for the SMTech 90 machine from SigmaPrint, http://www.sigmaprint.co.uk Yes, with vision you store images of two features such as solder lands or fidicial marks from opposite corners of the board. With

Just a guess: Are you printing your fiducials on the fiducial side of the board? Fidicial Side is for Vision Calibration, Bare Copper Side is for Offset Calibration (Step 5 of procedure says "copper side uppermost"). After printing 25 fiducials o

Can someone explain to me what I'm supposed to do after I have done the vision offset calibration procedure? The manual tells me to put solder paste down on all 25 holes of the stencil. After this the board drops down and the machine scans each fidu

Our Speedline MPM UP100 has stopped displaying anything on its monitor where the fiducial positions are usually taught with the camera images. The vga cable is working. Are there any commonly occurring issues with the vga vision board? The rest of th

Hi Deni, Thanks for your interest in my problem. It turned out that the power supply to the VGA vision board (the system in the black box)was faulty. I replaced it with a universal PC power supply and all is well.

Is it possible to put PCB to the screen printer with vision and on the board put sheet of paper then make print on the paper and it is the reference then i teach vision for example fine pitch aperture then remove paper and align PCB? We have semi-a
