Judging the pros and cons of design: Aside from the professional point of view, it can be distinguished by some methods of visual LED lighting, such as neat layout, small gas, orderly, and clean and straight.

Discrimination: Whether there is red glue on the back. (The solder paste process + welding fixture can also achieve wave soldering, but the cost of the fixture is high).
