Anirudh: When board fabs talk "surface finishing" they're talking about the solderability protection that you'd like on the solderable copper component mounting pads that you laid-out for each component: * Bare copper pads corrode very quickly * Corr

thankyou for you answer dude. As you mentioned in your answer that immersion tin finishing gonna cause many problems. So, immersion Tin option is ruled out for my purpose. So, immersion Silver is the option left for my purpose But, I have checked f

We recently purchased a Quadra Laser P&P machine from another company. The machine is in good conditions and we've been able to test most of the hardware functions of the machine, including fiducial recognition, feeders and header exchange. We feel

Thanks Sarason, I will take a look at your software ASAP. In the meantime, I've been able to answer my own question. Feeders can be associated to components by using the same component name in both tables. It's very simple in fact. These TWS Quadra

Hi dont play whit cap substitute ,you may screw up the whole design ,many ceramic decoupling cap was sensitive to applied voltage and temperature specially true for X5R and Y5V type. so a 4V cap may have right capacity at 3.3V but a 6 volt cap

Looks good. Have you done any work on feeding > form part tubes? I have a back burner project > trying to speed up the changover on our machine > with the vibe feeders. VisionBot works with cut tape SMT, is not necessary to have advanced mechani
