Are there any PCB manufacturers who can popularize PCB surface treatment technology?Is PCB surface treatment for anti-oxidation? How to choose between HASL and OSP?Does HASL work permanently?
We have previously introduced the general steps for using AD18 . This time, let’s briefly talk about an example of using AD18 to design a circuit board.
Open AD18 , first create several project files,
