When the PCB is finished, it must be mainly tested. Mark the broken plate of the short-circuit broken wire, or SMT may fix you later. In the case of Mosaic, the same location of the bad packaging together. Next is SMT welding commonly, want to look f

Hi, I have a small assembly line that consists of a Semi-Automatic Stencil machine, a Samsung Pick and Place, a small IR reflow oven and a wave soldering machine. The reflow oven is presenting the biggest bottleneck. The machine is a small IR (T960

Would you happen to have the Jig used to check that the component itself is in spec with UIC's general specifications? 1.) Component in spec. 2.) Correct 2.5mm pusher on the feeder / dispense head. Also set the conditioner guide where the comp enter

This week we assembled around 30 panels of a LED board, totaling around 350 boards. In doing so we had to work around a really crazy issue. 1) A board goes in, all components are placed perfectly. 2) Next board goes in, all components are around 5m

It really depends on the assemblies/components that need to be inspected and the available budget. 3D machines are much more reliable at detecting faults while not generating masses of false calls but of course they cost more than 2D machines. I ha

1. Palm down the GSM and open the safety cover to check input voltage +12VDC (at KDC2 3PL pins 2 to 3) and output voltage +5VDC (at KDC2 2PL pin 4 to 3) at the DC/DC converter. The DC/DC converter is located inside the control panel assembly ("Nose c

Omron is probably worst choice for AOI unless you have long series. Requires too much debug and there is always compromise between setting sharp criterias and get lot of fake errors or setting lose criterias and get boards with defects to pass OK. Y

Hi all, We are having a confusing defect with one of our client's boards. It is a large board, 30" x 12". The client supplies the LEDs, they are cheap overseas diodes, and it is not uncommon to have reels with the packaging torn. We have w

Hi Evtimov, Thanks for your response. Yes, the vapour phase is suppose to handle big and heavy boards, at least thats the intention. Well our thin board is like around 3mm which is not really thin. In our application the thicker the boards means more
