What is rigid-flex board?

Single/Double sided PCB

Single-Sided PCB refers to a circuit board with only one side covered with copper for circuit layout and soldering components, and the other side does not have any copper or electrical connection.

Double-Sided PCB refers to a circuit board with copper on both sides for circuit layout and soldering components. This design allows for more complex circuit wiring.

Advantages of Through Hole PCB Assembly

Short production cycle
The manufacturing process is relatively simple, the production cycle is short, and it is suitable for rapid prototyping.
High reliability
Since there is only one side with circuits, the possible via problems are reduced, and the reliability is high.
Flexible wiring scheme
Both sides can be used for wiring, the design is more flexible, and the wire length can be effectively reduced to improve electrical performance. Reduce the size of the circuit board: Higher wiring density allows more components and connections to be accommodated in a smaller area, which is suitable for miniaturized design.
