If you refer to having wrong resistor or capacitor value, the only way is to automatically measure the part value. Mycronic pick and Place machines do it on the fly, ASM machines have feeder where part is measured....other main brands probably have

Let me rephrase my question. How do you avoid having errors in your SMT set up? IE xxx part goes in feeder slot 55. We currently have our quality department do a machine check but small errors like this can still go unnoticed.

Barcode/scanner configuration can still lead to wrong parts mostly when changing reels. The root cause is still the line operator, because instead of scanning the newly set-up reel, he/she scans the old reel because 'it's easier' for them. I have wor

I'd recommend checking with the manufacturer of your SMT equipment and checking into the feeder verification solutions they have. Combine that with a buddy check and true first articles before the line can continue to run the balance of the job an

A solution that could placed on any machine is a first check that places a component in a fixed location and then the 2 pin component is read with a meter like a HP component measuring system. Similar for transistors and FETS. IC's are probably not s

Jinesh, My initial suggestion is you have too much solder past. Please try to reflow a few of these parts without solder paste. Colse aperture, put some tacky flux on this part location and give it a try. I bet you will not see any voiding.

Finishing off tidying up/ cleaning a DEK 265 mk1 and inside ( front/centre ) are 4 silver pots and a pressure gauge. All the labelling is unreadable. I know the gauge is sort solvent dispensing, but no idea on what the pots adjust. Can anyone shed a

Reason I ask is because I've never really paid much attention to the cooling rate, but I'm currently running a 10 zone oven and using all 10 zones for heating whereas I've almost always used a 10 zone as 9 heating and the last as a cooling. I'm curr

The ideal cooling zone curve should be a mirror image of the reflow zone curve. The more closely this curve mimics the reverse of the reflow curve, the tighter the grain structure of the solder joint will be upon reaching its solid state, yielding a

I have one Pemtron SPI TROI-5500H machine and hard drive crash on it. I am trying to get it back up and running. I install the XP and old version of TROI software. Currently i am trying to calibrate the machine and no luck. During the PZT calibration
