Abstract
The invention discloses a membrane circuit board including a substrate, a plurality of first signal pins and a second signal pin. The first signal pins and the second signal pin are disposed on the substrate. The substrate has a first edge. Each of the first signal pins has a first terminal, and the first terminal has a first width. The second signal pin has a second terminal, which is disposed between the first edge and the first terminal. The second terminal has a second width. The second width is larger than the first width. Accordingly, the membrane circuit board may have high error tolerance and better quality control efficiency.
