YunSun LED

During the 2014 trip to China, our supplier YunSun was kind enough to pick us up in Shenzhen and give us a tour of their factory.

Basic LED

Although SparkFun has been using and selling LEDs for over 10 years, I had never seen or really understood how they were made. I let Merry Xiao, our main contact at YunSun, know that we were very interested in learning, so she arranged to give us a tour on a Saturday when the factory was closed. We were extremely grateful!

This is Mr. Si the proprietor of YunSun with the most hilarious sense of humor. He's holding a project that my wife Alicia Gibb is working on. Merry joined us as well and helped translate.
