We bought a new lead free wave from Electrovert about a year ago and opted to not have the nitrogen options installed on this machine. We could not justify the cost of the nitrogen used versus the benefits that we would see. One downfall is that you

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

Thanks for all of your suggestions. I ended up borrowing a Pace Worldwide PH100 Preheater, which worked like a charm. I'm in the process of purchasing one for our own shop. I had to place the aluminum pcb directly onto the PH100's ceramic heating pla

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

HOW THICK IS THE BOARD? IS THERE A LOT OF COPPER IN THE BOARD? DOES YOUR CUSTOMERS PROVIDE HEAT RELIEF IN THE BOARDS BARREL DESIGN THERE NEEDS TO BE PLENTY OF ROOM FOR LEADFREE SOLDER TO FLOW, DID YOU CHECK YOUR PIN(LEAD)TO HOLE (BARREL) RATIO? N

We have been using InoAuto carts since 2015 and we have a number of them on our floor. We bought few of their passive carts on 2014 IPC show and that's how we know them. Although we already have efficient vertical revolving storage systems, we have

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
