Hello, We use OSP-finished PCB. One component (transformer) will be delayed (approximately 4 months) to getting in our hands. We want to partially complete the PCBA (both SMT & MI) in the meantime and later insert the transformer upon arrival thr

Yes, there are two lengths. My MPM UltraPrint 2000 HiE has trays protruding from the machine about 15 cm, I think. I'll check with the company tomorrow to see if there are any numbers in the manual. I have a link to the part saved - maybe check it ou

To me, it sounds like a bored quality engineer looking for problems where none exist. I will say that the terminal velocity of a falling reel is below the threshold that would cause damage to typical components. Therefor, it is safe to use a reel th

Next step trace the RS232 cable. Check all output voltages on your power supplys, b oth loaded an d unloaded. Note any differences. Check he impedancesa of your loads ie is your 24 volt load only measuring a few ohms. You may have a short? sarason

No electrical schematic sadly - and there is no sign of a connector under the mounting hole, so I'm guessing that it's never had this function. The actual light tower on it looks remarkably similar to a DEK printer one, so there's a chance that the

I use a DTF instead of PTF, but one thing I wondered reading this...Which pocket do you designate as "First Pocket" for your tray in your Feeder.db? Could this be affecting the XY position being returned by the machine? For DTF I use upper left. Shou

Hello Magyar, the main reason is supply chain disruption due to covid in china. The regular lot transformers failed in IQC, so we ordered a new lot but it's delayed due to covid. Meanwhile, some other components (bare PCB, capacitor) will be out of s

Has anyone ever created a validation process for their SPI? I recently took over the programming of our Kohyoung spi's and was asked how do I know the settings I set are correct. The only answer I had was visual inspection under a scope and the set

Hi, I think this can only be done by a lab analysis by the machine supplier + a calibration tool they give you and you do a repeated number of measurements periodically. Or you can just call the service engineers out and they do it themselves. You sh
