7 segments display. Each of the segments have two different states; on and off. Different combinations of ‘turned on’ segments are going to result in different numbers and letters.

Using the least GPIOs to control more segment display with using 74HC595 swift register IC.

Three common PCB problems are summarized and analyzed, hoping to bring some help to everyone's design and production work.

- PCB Board Short Circuit

The biggest cause of PCB short circuit is improper solder pad design. At this time, the round solder pad can be changed to an oval shape to increase the distance between points to prevent short circuits. Inappropriate design of the direction of the PCB parts will also cause the board to short-circuit and fail to work.

- PCB Open Circuit

When the trace is broken, or when the solder is only on the pad and not on the component leads, an open circuit can occur. In this case, there is no adhesion or connection between the component and the PCB. Just like short circuits, these may also occur during production or welding and other operations. Vibration or stretching of the circuit board, dropping them or other mechanical deformation factors will destroy the traces or solder joints.

- Loose or misplaced components

During the reflow process, small parts may float on the molten solder and eventually leave the target solder joint. Possible reasons for the displacement or tilt include the vibration or bounce of the components on the soldered PCB board due to insufficient circuit board support, reflow oven settings, solder paste problems, and human error.
