Interesting, never heard of using wax as a coating mask. Not sure how well the AR coating would hold up to a hot alkaline wash (unless you have experience with it), but that stuff usually starts to flake off/de-wet if you just look at it wrong. I'm

100% agree with dwl. last year one of our 3rd party delivery partners got rear ended resulting in about 30% of a $120,000 shipment being written off. If it hadn't been for foam lined flight cases we would have lost the lot. Also for smaller 3rd pa

hello, I suppose you didn't put any placement offset in the component placement settings. did you perform the general calibration of the lasers? with the supplied calibration tool that comes with the machine. check MSP parameters, as there might b

This problem frequently becomes an issue with lead free solder paste, because it has very different rheology than leaded pastes. While not a 100% of the time, the squegees are very ofen the cause. When the regular blades are used (steel squegees), th
