We have a couple of Zeva/Juki PM570L's. One machine has developed a fault with the z axis motor. It is continually 'buzzing', we have checked and there is 24VAC on it. Although even on the other machine there is AC voltage on the motor. We have sw

Advertisements are not always 100% accurate on technical issues. You don't want instand static discharge. A wrist strap with no resistor could cause that. Therefore put in a current limiting resistor to make the charge dissipate slowly. Does anyone

Good morning everyone, I'd really appreciate your input on some of the best ways to create a dry environment for MSD storage. Line down-time is considerable when we have to pull of and reload 20 reels of MSD parts at the beginning and end of each s

Well Orbotech is basically out of business. They have sold their AOI to a company that is a basically a reseller. What that means is usually they have no people to improve software or make changes to improve the system. Not sure how Sony supports th

Thanks Dave. What you say makes complete sense. We ran a job a short while back in this way (though without bonding) and found we had a much higher than normal failure of the BGAs which I can only attribute to the secondary reflow. As I have only got
