Hi, I have recently been asked if I had any information on the voltage capacity of a solder ball. I asked around and did a web search but came up empty handed. Usually people are concerned with the current carrying capacity of bondwires, flip-chip

My regards to everyone. I have to agree with previous message. I've written macro in excel to modify protel pik file to whatever form I need (and I need PCB file for MYDATA) Takes about 5-10min to come up with workable program. the only problem tha

I searched the archives and couldn't find anything specific. Our designers would like me to wave solder an SO18 on an upcoming product. My IPC standards have land patterns, but no recommendation on wavesoldering. This is a higher pin count than we

If I were you, I�d be concerned about waving your SO18 too. What is a SO18? Who makes that package? Regardless, it should be a can of corn, if you: * Orient it so that leads on opposite sides of the component see the wave at the same time. * Incre

Dave, It will all be about the same - changing atmospheres does not affect your heater output. You may experience some differences in the way your solder joints look (a little duller), but with some of the newer pastes out there, you can overcome i

Ian, The vision should recognize it; given you've got the correct Part Data. To run 0402 effectively with a CP3 you need: 1. A good, I mean real good, CP4 style feeder for 0402 (1005) 2. 0.7mm nozzles (get from second-source supplier such as WT in

I am receiving a "cognex not found" error upon bootup of a MPM AP24-X stencil printer. I have checked everything I can find between the cognex computer and the one in the machine. Has anyone experienced this before? Any ideas would be greatly appr

I�ll bite ... Why can�t you calculate LSL/USL values from your control charts? We find that LSL/USL values generally are unknown. If you are seeking a text on statistical analysis consider: "Statistical Process Control for Surface Mount Technology"

It is apparent that you have evaporated the flux before you reflowed. You got lucky when the paste slumped and you didn't get major problems elsewhere. A more reliable solution is to adjust the stencil apertures for the part that is experiencing bri

Get a profiler for your oven. To say "we are not sure" and "we think it might..." shows you are running with a WAG (Wild Ass Guess). Not a good place to be if you intend to produce anything reliable, with quality. Run your profile and verify that yo
