No, the accuracy of chip shooter should be always as 3 mils tolerance. If for some reason, the tolrance is 4 mils, you should consider adjust your equipment. If your chip shooter is performing well, I would suggest that you measure the variation on t

Is there anyone who knows what the influence is of the dip-fluxing process on the placement accuracy of a flip-chip. If you perform dip-fluxing after component alignment, the component may be displaced on the nozzle; if you perform component alignmen

Hi Simon, Yes, red glue should help, assuming that it is being dispensed by a glue dispenser. For stencil printing I used yellow glue in the past (can't remember the brand). Your pick and place machine should be able to achieve on it's own 35 um

Are you guys providing adequate board support during glue dispense and placement? I've had this same problem with 0603's that I was able to correct with adequate board support. Also, if you're using a Fuji glue machine, what are your temperature sett

Linux, The amount of error that you are describing is about the thickness of a human hair. Unless you are placing 0201's I can't understand why .12 is an issue. There are many factors that can effect placement accuracy on a CP6 For instance: 1. M

Thanks Rob. Our concern is placing tiny components side by side at a minimum pitch, along with fairly large BGAs and TSOP2, which are themselves, having small to fine pitch leads. yes, accuracy in placement in our application is crucial, yet, what i
