ALOP Open Source_[Commercially available industrial grade] ACDC flyback switching power supply 5V2A module

Schematic diagram, wiring diagram, physical diagram,
short-circuit test,
the first available ACDC open source project without pitfalls on the entire network,
and if there is no problem with welding, it will definitely succeed.
There is a self-restoring fuse at the high-voltage input end, which protects the safety of the module itself
and has overheating protection. The recovery output after overheating is relieved
has short-circuit protection. If you are not careful,
use a 1210 starting resistor with a withstand voltage of 400V. The withstand voltage of 1206 is only 300 (but also It can be used, a little overloading is not a big problem)
According to the thermal image, the output diode is the hottest. You can choose a Schottky with better performance according to your own financial resources. The 5824 used in thermal imaging is recommended for
PCB proofing. It is recommended to select the specified location to add No.
Due to the large area of ​​copper coating on the PCB, it is recommended to use Teppanyaki welding. It may be more difficult to use a soldering iron (the temperature cannot be raised).
 
Reminder: I don’t know why the copper coating in LCEDA becomes a grid link after being saved and then opened,
but the design rules There is no problem with the configuration,
but copper laying like this is not possible. Direct connection must be used for copper laying.
There are two options, use gerber for proofing directly, or re-lay copper before proofing.
Then why is the schematic not displayed?
