So your thermal cycling test is putting these solder joints into reflow (183C + if they are lead joints)? Must be quite the test! Tell us what pad sizing and spacing you are currently using.

I am looking into pick and place machines that are spec'd to place 01005 components. Does anyone know of a inexpensive make(50 - 75K $ new) that can place these parts. So far all that I have found are 150K and up. Thanks

The missing rate spec. of normal machine is under 0.3%, for our experience 0.1% is normal for average, if you can maintain the machine well, like the nozzle cleaning, feeder maitain...you can keep the 0.05%.

Ron, I'll bet you have the Ni/Pd finsh on these components! We have had the same problem in our shop. Not knowing the Kester spec. we had to raise the max temp to 220 Deg. C and increase the time above liquidous to 60 seconds or greater. It seem

Manufacturing already tried to get a design change but no chance. I guess because the designer is afraid the components could get bent too much if they are mounted with a stand off. Of course everyone who has to manufacture this fist sais: why don't

IPC SM 782 has some info on wave solder pad geometries. We usually like .03" spacing to any uncommon conductors. I would assume that you are seeing shorts between components and vias or adjacent parts? Russ

Hi I am having solder short defects on the bottom side with SMD devices that run through the Wave solder. May you let me know any IPC guildelines about the spacing, orientation or any other design guidelines for avoid solder defects with SMD device

Not sure what you mean. 0201's and 0402's are both on 8mm feeders. Juki's will do simultaneous picks an all 8mm feeders no matter the component size. Your feeders need to be maintenanced and calibrated to reliably pick 0402's and 0201's. I hav

Darby, I'm not completely sure I understand. Juki machines have what is referred to as a multi-head. The offsets between the heads are the same as the spacing between 8mm feeders. So the (6) heads all come down at once and "gang pick" from 6 8mm fee

What do you want to be certified? So, do you have a specification control drawing for each component that defines your expected performance capabilities for use by your buyer in acquiring these parts? If there is a reason to fabricate parts to your
