I'm concerned by the solder spheres in the via on the first picture. Are these boards mis prints that got washed and printed again? To me it almost looks like someone washed the board, but left a lot of solder paste on it. The lack of flux prevents

Hi,I have been investigating this machine for the past month and technically i am impressed with it's capabilities. It seems easy to program and does all this things i would need. I'm still in process of evaluating other machines so have yet to mak

Hi all, I have a GRUNIG G-CHECK tension measurement tool, I need to prepare a calibration report internally. https://graphcom.gr/product.php?lang=en&id=128 Measuring range between 7 and 50 N/cm Thanks for sharing any useful calibration instruction

Thanks for reply, in fact, my question is how to calibrate the tool itself, it has some load spring and a gauge moving according to the tension of the mesh. I was wondering if I can make 2 different tension sets to have different comparing values, th

Thank you for your response. I watched your video and I liked the solder ball rework method. However this is not related to the issue I'm experiencing or the way I intend to fix it.

Seem like extra soldering would really helps it. Adding solder beads by using pick & place machine is more of a consistent way to add extra solder where you need it the most. No matter how you modify the stencil, there is still limits how much you ca

Hi, Mainly concentrate on 2 subjects: 1- Cleaning of Misprinted PCB (always use best neutraliser to remove paste from PCB), 2- Underneath Stencil Cleaning - Use good stencil cleaner (rather than IPA) to wipe your stencil. Because both the above said

Is the wheel that drives the belt in alignment? I assume all the bearings are turning. We've had bearings in the past be on the edge of seizing in our end pulley's. Tightening too much could cause it to turn harder, causing the belt to jump off. Coul

We previously labelled PCBs after assembly but before AOI. Now we need to trace panels during assembly as well, so have the need to apply labels before the assembly process starts. Our stencils are thus not stepped to accommodate labels. I suppose t

thanks for help guys. I changed HDD and mounted image from a working machine then I ran a calibration. It still moves paste left and right but distance is much smaller so prints are acceptable. I have a spare vision card will try it tomorrow. Do I ne
