JLCPCB: There may be some components that generate high heat, such as the regulator, on the PCB. In order to prevent these components from being damaged, I am explaining PCB cooling techniques for you via EasyEDA of JLCPCB. Especially if your circuit has to be fed with 12V and you are doing things that will draw a little more current with a 5V regulator, you will notice that your regulator gets very hot. You want to prefer an SMD regulator in your circuit. No problem. If you are not going to draw more than 400mA current, I am sharing a few circuit tricks for you. In this article, I will not go into technical calculations for the sake of appealing to everyone. I will just tell you the methods. If you really want an article that includes technical calculations, you can let the JLCPCB team know. I will also prepare that article for you.

JLCPCB SMT technology allows fabrication yield. Compared with THT or hand soldering, SMT is more suitable for automated production. THT requires different insertion machines according to different components, each machine needs to adjust the assembly time, and the maintenance workload is large. SMT can install all types of SMC/SMD by using one placement machine with different feeders and pick-and-place pin, which reduces adjustment preparation time and maintenance workload. Compared with JLCPCB PCB assembly , hand soldering has a high risk of making defective boards. In addition to the solder paste printing machine, pick and placement machine, and reflow oven that needs to attach electronic components to the circuit board, the JLCPCB PCBA service has enough inspection equipment.

JLCPCB is a Chinese company famous for manufacturing printed circuit boards.
