Our observation also is that the tape size is too big for the chip which allows the tape to move around. With this i would like to know if there is is a setting in the machine that would slow the feeding rate. We are using juki mounter 2000 series. A

Yeah, them soldering machines sure got some demons in them...My waves used to get blamed for wrong polarities all the time. Sneaky little devils used to pull components out of the boards, flip them around, and get the pins back in the holes while

Hello all Good morning. I just want to ask with you guys about the problem that we always experienced in our production. We could not get our target ppm due. to inverted placement of chip resistor. We are using 2000 series juki mounter and cf03hp j

Board support will almost always cause the part to be miss-mounted. The bouncing affect of the board can cause the part to bouce off the board. BUT, you never stated where the ends up or anything like that. Is the part on the board but just floppi

I have used Multicore MP-100 and Heraeus F380 pastes for a while, and experienced very few dry joint problems. May be worth checking if the pad size and/or spacing are to the correct specification for the components. Check the date codes on the comp

I've also seen "as received" defective devices. A tier 1 EMS I was working with put down an entire shift worth of these devices before it was noticed. Their rework costs were $$$. Just goes to prove that there's no free ticket and when bean counters

Too fast heating/cooling rate in reflow (look at mfg's spec.). Z "overdrive" on pick and place or chipshooter though unlikely I would say. Depanelization method (bending a scored board to break it is tough on things). Bad PCB design - cap. too clo

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
