Wow! Thanks Jim!. When the ejector pin hits the piezo ceramic sensor, the sensor will produce a voltage difference between the top and bottom surface(that's why i need to connect the tracks on both sides) which i will measure. The sensor does not ne

Hi all, We traded our 4c work holder for a transport with another company. Eventing works, except that when I put a board in it does not index. All the other functionality seems ok. The rail width moves, I can eject the board, and it knows it needs

Larry, We once had a problem in which the IPIII would pick on one area of the tray and not on another. It turned out to be the vacuum hose. There was a small crack/cut in the hose, and when the robot (and attached hose) was in a particular positio

| Here is a good one for ya. Our IP3's MTU will not pick QFP240's out of cavities, 10, 12, 13, 15. This is a 3X8 tray. The listed cavities are also the closed cavities that are used for tray eject. There is plenty of vaccum, the nozzle comes down

What kind/brand of machine are we talking about? Are the missing parts randomly distributed or are specific to a feeder/placement/pattern? Does your machine remember where to resume placement if you reset it in the middle of a pattern placement? We h

We just got our used Fuji IP-1 working well. Sometimes during testing of a new program/pcb we like to stop the run and re-start with a clean board. When we make the IP-1 eject the unfinished pcb and start with a new pcb the IP-1 does not scan the f

Thanks for taking ur time to answer this. =) The pick and place machine is just pick from wafer(on tape) and place into waffle pack. I read from some of the sources saying that the ejecting needle and the vacuum pick up bits could cause the die to c

If you think the problem is occurring in the box and it is wide spread, consider replacing your solder paste with your paste supplier. There are paste formulations aimed at the solder balling issue that some LF pastes create. On tuning your reflow r
