Hi guys, glad to join in this big family and really nice to meet you all. I'm a PCB & assembly sales engineers in China and I have been in this industry for nearly 6years. If you have any question about this stuff, feel free to contact me and I will help you to work it out together. It's really a happy thing to meet like-minded pepole and grow together. I believe we are doing great things and we are moving the world to a better place. Sharing a picture of a PCBA board that used for protecting Li battery. 
Sincerely
