Why do you want to design the circuit on the board to be curved?
We will find that the circuits on the board are curved. Why should we design this? Three reasons are given below. First, if the lines in the board are designed to be straight, the board area will increase by several times. In today's era of pursuing exquisiteness and compactness, the area of the

What are the factors affecting PCB impedance?
When the line is less than 25 mm from the edge of the board, the line impedance value is 1~4 ohms smaller than the middle of the board, and the impedance value is less affected by the position when the line is more than 50 mm from the board edge. Next, it is recommended to preferentially select the

The difference between positive and negative PCB boards
Negative film board: Generally speaking, we are using the tenting process. The liquid used is acid etching negative film. Because the film or copper surface is transparent after the film is made, the unnecessary part is black. After the line process exposure, the transparent part is chemically harde
