Please clarify what you mean by "bouncing". Small up and down motions around home position? Full stroke of table movement up and down? Or somewhere in between? Does it start as soon as servo power is applied? Or not until table home movement is initi

If you're 100% certain you have the correct nozzle for this package you could check to see if your PnP machine has an option for "Auto Adjust Pickup Position" or something along those lines and try changing it (if it's currently on, try turning it of

During the initialization process, the table will make small movements up and down, and occasionally go all the way up and back down again, then continue to bounce up and down maybe an inch of travel, it never completes initializing. I wasn't operati

So you run one side, and leave the boards sit in temperature controlled environment for 3 days before running the other side? Are they ENIG coated? If so, they are probably ok. You could always keep the boards in your hot room. I assume this is du

Thanks for all comments. Process was adjusted normally, problem was in PCBs. Microsection of bare boards confirm that the copper thickness in troughholes was unsuffient, sometimes below 10 microns, on soldered boards where there were a problems durin

@ProcEng1 Yea. Mostly is ENIG surface finished PCB. Sometimes there is OSP board faces issues like part shortages and is forced to hold the production and resume the second process after a few days. So, would like to know any special control on keepi

@charliem, For the clean process board using "water-soluble" fluxes, we will send the board to aqueous wash with DI water first if not able to manage to proceed with the second process within 24hours. Then, keep the board under room temper

If you are currently using a Mirtec machine, then you will continue to choose this brand of machine when you replace the machine. If you are familiar with TRI, Koh young, these two brands are also good. Many clients are using them. If you need to kno

I had the same question. We have custom nozzles made by Count on Tools. I believe we found urethane works the best for the silicon domed LEDs. Have you slowed the feed rate down on the feeder? Also adjust the top tape to the back slot on the feeder.
