If you suspect a short, check the resistance on a new board that hasn't been powered up. The data sheet should give you the junction resistances that you're looking for. Double check against a component not assembled on the board. If you measure a

We have a product which is supplied on 8mm tape. One customer recently commented that their SMT equipment couldn't handle the part as the tape was measuring 8.5 mm. Our actual measurements of this tape were 8.33 and 8.36 mm. I believe the max dime

Dear members, Recently we have found that solder mask thickness variation could lead to solder balling under QFN packages for a high reliability device. Is there any industry proven method for solder mask thickness checking? Any equipment or any me

yoru x-ray supplier should be able to help however you can do a rough cut calculation byt just printing it out and measuring it, your interested in ration (%) of the void and where in the joint it is to tell you it it's really an issue. Also importan

Hello, my fellow SMTnet users. I've been using my Quad 4C for some time now and I come to you with a question: What's the difference in the measurement of a leaded and a non leaded component, why does it have a different function for each one (FUNC

Sounds to me that the issue may be with vacuum and part of it, after the segment is put there's a little measure of air that pushes the segment far from the spout in MYDATA we consider it a kiss in my office, have you watch that the air that "puffs"

Hello DWL, Thanks for the response. I've measured the components with a micrometer and set the sizes. Maximum tolerance on my machine is 20%, and that's what I'm using. If I do a manual scan, the measurements are exactly right (and what I've set up

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

I was consulting the manual of the machine and to measure the tension of the x belt I need a frequency counter and two prisms but I don't have these tools, is there any other way to measure the tension?
