Hi Good Luck, I worked a long time with THT components like you discuss and boards totally or partially populated. Dee Machines, Electroverts, Hollis and an other and never had the kind of problems you are listing stayed with us forever. I mean you

I agree with DDave, You have something else wrong! .100 dips with .05" lead protrusion should not bridge (in fact I would think that it would be almost impossible). Tell us about your machine, (laminar flow, A-wave, etc.., size of nozzle, wave heig

Tell us more about the location of the bridging [ie, front-to-back, back-to-back, front-to-front, etc]. Thoughts are: * Your annular ring around the hole seems large. You have 0.007", consider 0.003" to be the minimum. Your board fabricator can gi

Call 1-800-737-8110 for tech support. They can give you the N2 supply specs for the 650C. You should consider the cost to convert the Contour to a standard Lambda vs. the cost to bring in N2 and the consumable costs. Tech Support can give you the ret

You may want to consider a Nitrogen Generator as an alternative to portable Dewers. Reduced handling,no gas contracts and usage on demand will cut your liquid nitrogen costs in half.A good rule of thumb for consumption guesstimating is if you use two

I estimate the costs about the same but we build in batches so the wave only runs a few hours a day. We do complex boards so I think its worth it plus you have to keep the machine awhile to recoup the investment in the new nozzles. If the market gets

No cell phones on the floor under penalty of suspension or worse. They are allowed emergency phone calls as many of the women in production have kids in day-care or school. But the dept. supervisor is the one answering the phone and decides to take a

Hi Dave F As usual an interesting issue. Employees working in hazardous environments and critical tasks were the safety of the personnel and the jobs are at risk; they should not be allowed to use any communication or entertainment media. Such means

This thread brings up a interesting topic. A supervisor is answering phones and deciding whether or not a personal call constitutes an "emergency" or not. Is it ethical to inquire about anothers personal buisiness? In our sue-happy society I pity the

We use an EKRA E4 printer, but the concept sounds the same as far as the fiducial alignment goes. I have found that SOT-23 components work the best for fiducials - and I always make it a point to use them on our older PCB's (where the screens do not
