The cheapest method I've found to measure anything in that size range is a reticle for a stereo microscope. I don't remember the resolution but it was 2 or 5 mil, I think. It's not rocket science but it's a nice tool for small scale measurements tha

I've had experienced this issues here with our GSM's Flex heads. Try this: 1.- Clean your linear scales with alcohol and a lint free cloth. Both the X and Y. This one has fixed the majority of our errors when one of the heads just stops for no apare

Patrick, Back in my rich OEM days, i actually DID measure mg/in^2. I bought a scale, which measured in mg, specifically for this. Basically, took a blank PCB, took a "before" weight, sprayed it, and then took an "after" weight. I measured at diffe

4.4 Determine the amount of flux on the board. 4.4.1 Get a piece of corrugated cardboard and a weighing scale accurate to 0.01 grams. NOTE: Use cardboard with alcohol fluxes to slow their evaporation and get good data. 4.4.2 Weigh the cardboard. 4.4

We had some materials management brainiac insist that every component of a product had to have an exact quantity stated on the BOM so we had to weigh every board with and without paste printed. We rented a 4 place digital scale, weighed 5 of each boa

We currently use Unisoft on a limited basis. It was purchased as a low cost solution to track a specific product until we can roll out a more robust tracking package. We are currently moving towards Optimal Electronics. I think their quality package

No reason it wouldn't. Our convection ovens are based on the exact same concepts that pizza places convection ovens are. Just probably on higher power scale. Heck you could probably even use a thermal profiler to get a good recipe down. However I do

First thing to do is make sure the y-axis encoder scale is clean. Usually on these machines you can view the status of the read head or there is a led on the cable from the read head that will let you know if it is working correctly. Green means its

I'm just throwing this out there, but is anybody manufacturing large footprint flex circuit PCBs? (I'm talking assemblies 18-36" in length) We're in the midst of quoting a new opportunity that involves several flex circuits of this size. Currently o

I had 2 Contact 3AV and 2 Contact 3Z machines. Basically the same as 3AVX machines. Both models are good machines. They are perfect for small production and even medium production size lots if you have multiple machines. Super easy to operate and
