would any body be able to supply me with infomation on how to adjust a quadalign unit,as a unit on my line will not pick up 0603 resistors,but will pick up thicker 0603 caps. My manuals offer no help.I have run the aligner calibration with the cone t

I never calculate it when I setup a profile...I have a feel for our fluxer setting and adjust based on belt speed and width. I also have different nozzles and a pressure setting to play with. Inspect the bottom of the board for good coverage. Runn

We do continuous reel-to-reel flex circuit PCB's with a typical "panel" width being 12". (The PCB pattern repeats every 12".) We have done some product that was 24" by doing one half of the board then the other through the screen printer. We have

We are currently wirebonding MCMs with surface components located in very close proximity to wirebond pads, which are gold plated. We are ball bonding with 99.99% Au wire. Normally we do not have problems, however if product has been reflowed seve

We have a Viscom SPI S3054QS. Yup, the machine offers a quite good speed. My board dimension is 150 by 250mm. The cycle time is only about 24 sec. The analyze time is only about 10sec. You can make your loading faster, if that's what you needed. I ha

We have yet had the need to use local fids on our boards you must be putting down pretty fine pitch parts that are needing the acurcey if it is failing fids that are within the search area then maybe its somthing else size our lighting it should fin

Thanks for the input. These are 80 pin fine pitch connectors on arrayed flex circuits. We have found from experimenting there is really no good alternative but to use local fids. I found what I'm doing wrong - I needed to move fid finds and correc

I work for a CEM. We are having some quality issues with some pcb's that came from China. (I know, big surprise) Can anyone with pcb manufacturing experience look at some pictures I have and give me an opinion as to what could go wrong in the pcb man

GSM's are only 500 to register with UIC. There are a ton of GSMI's around. We have always run chipshooters with GSM's and now the new Advantis machines from UIC. GSM's are very accurate, but a bit of a pain if your running lots of chips (thus we r
