If you have an older machine that has cyberoptics you might want to try to put a pickup theta of 90. I believe there was a problem with that type of part. Also use non-leaded alignment and scan the part near the top of it. As for 0402 parts.........

Those Panasonic machines should be able to tell ya pick-up rates form the feeders and shape code errors (components it doesn't recognize). You will probably get a more pick-up errors than anything else. Most of this is due to plastic tape versus pa

Hi - I'm looking into possible low-end pick/place machines (in UK) for prototype/small runs - taking the next step from plastic stencil/hand place/pizza oven, as my local subcontractors can't offer the fast turnrounds I often need for short runs. Bud

Ive used a Mirtec machine for 3 years MV3L with side angle inspection. Mirtec has some issues documentation, and repair plus. But there machine is impressive and the AOI software is good. We can find about 90-99.99% of all errors using just the 5

Wayne, I haven't seen anything indicating that Gold Immersion is necessary for lead free... However, it is my companies preferred finish for lead free assemblies. We've taken this stance for the following reasons: 1. Better solder quality on th

| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

We are using a low end Air vac system to place the BGA's. We have X ray we can use. Our CGA's as well use this system. They are one off parts that are above the 20K a piece range. So I have been tasked with making sure all of these procedures are the

Thank you for your comments and questions. Did not realize that they charge for the registration. Was just reading some info on the service contracts through Contact Systems and saw they required the system to be registered. One of the brokers that
