It's difficult to tell anything from your picture. But playing the odds, I'd say it's not "gold corrosion." It is very difficult to corrode gold. Gold is a NOBLE metal. From Wikipedia, the free encyclopedia In chemistry, the noble metals are metals

Anthony, I hope that your new production line has been running smoothly for you. I would like speak with you about who you are getting your bare PCB boards from. My company, ICAPE Group has 35 manufacturing partners in China. Full service provide

Thanks for the suggestions, Caurbach. We do have the occasional lead jumping out even at this length, hence why we've been hesitant to cut them shorter. I have the wave nozzle to PCB distance set as per the machine instructions (4mm I think?). I ce

Are you reflowing them and they are coming out of the oven bad? If so, what kind of oven are you using? What kind of LEDs? What kind of solder? Mass of substrate? Have you ran a profiler through your oven and compared the plot to the solder's spec

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

The very best batch cleaner I have ever used, and I don’t mean by a small margin, was an Electrovet MCS1000. I kept that machine running a very long time, but a software problem ended up being more than the company I worked for was willing to underta

In fact, we can solve this problem easily. AOI only check whether the IC is soldered well. But we can ask our technician to make a test first to control the reflowing temperature and time. 1. using tool to test the temperature between the bottom IC

This will depend on many factors: your reflow oven chamber size, your oven temperature controller, the speed of the conveyor, size and mass of your PCB, etc etc. In practice you should adjust the profile for each case if you want to set in the optim
