Will the Pb part handle 240C? That is the first question that you need to answer. If it will then yes I would run the pbfree paste and profile. I assume that all other components are pbfree. If not, the same questions will need be asked as for th

Its it possible to post a picture from right after reflow? To see what we start with and compare the difference after 5 years. The grainy structure is not as much a concern as the growth-like appearance on the boundary of the solder. What paste al

You guys are all joking right?! There aren't any contaminates in your solder, the different colors on the surface are completely normal and even expected. The top layer of solder oxidizes and the structure of the surface resembles crystals, refract

OK , the H6H file is a binary structured file and can be read if you write a program in VB etc to extract the info you need, would take some time to sort out where to get what in the file, juki would no help you here.... Assuming you need placement

Well, typical content of Pb in Sn/Pb polating is a few percent (just to mitigate Sn whiskers growth). Therefore, the lead finished with SAC305 won't be much different from those finished with Sn/Pb. You can make one or two cross-sections for sanity c

Looking for an answer about file structure on CC. It has been 10 years since I have done anything with CC so bear with me. After you have created a job file that has all the components on it and the polarity parts have a pin 1 indicator, I need to

I'd think about database structure and programming aspects as well. I'm cleaning up an implementation where the parts were taught as they appeared to the AOI programmer irrespective of the Pick & Place data/libraries. Lots of rotation fixes, parts

Hello! I've had the same problem about one Jear ago. We had exessive building of voids in the solder joints. I recomment to take a pincer to break off some of the components. If the solder joint is good, the copper pad will stay at the solder joint
