It will vary by placement machine mfg. and type. I had 4x Fuji CP3 (turret chip-shooter) and 2x Fuji IP2 (split axis general app-fine-pitch)and tracked component shrinkage at 0.05%-0.5% on average. Above 0.5% triggered maint. & process eng. response.

I've never worked on that machine but I won't let that little detail stop me from commenting. Are your nozzles clean, and have you checked your vaccuum levels? On every machine I do have experience on, management doesn't allow time for proper mai

Tod, I am a user of 4797 and we too have this problem. A question regarding nozzles. How could I check whether they are worn-out? Only in vision check? We have worked for about 2 years without changing them, but worked just one shift.

Personally, I'd run 1 time recovery, and depending on chip-shooter model, I'd use 2nd station parts detection on larger parts with error stop. The situation you decribe, a couple caps an hour would'nt stop the machine unless they came from the same f

From the equipment side in the last 10-15 years ? I suppose the whole push toward modular machines. Less floor space, increased capability in a single platform - speed of a traditional chip shooter, common spares, blah blah blah. Some of the recogn

If it were my money and I had your specifications to achive, I would go Mydata. One platform, chip shooter, optical centering, mechanical centering, electrical verification (that works)smart feeders that work, etc.... I have worked on several platfor

Hi, It is a bit hard when you want to get clear answers from people on their experience when a manufacturer jumps in, because it skews the thread. Is there anyone using an XP chip shooter? What do they think? I really like the design of it, and th

The way we do this, is to tape a transparent film to the PCB. The printers and chip shooters can read fiducials no problems. Once it has been run through SMT, simply remove the tranparency film and the PCB is ready for use, no mess no cleaning and yo

Your not using a jaw machine? Had a problem with jaw machine once. Could hardly see the cracks but give it a little heat and the crack open up. Adjusted jaws but ultimately had to move the cap to the chip shooter upstream. Moved the cap to the ja
