Electronic Double Sided Rigid PCB Board Printed Circuit Board 1.2mm Thinkness

Double-sided carbon oil process

product  Description:

    Double-sided PCB, also known as double-sided printed circuit board, is a printed circuit board (PCB) with two-sided circuit connections. In this kind of PCB, the electronic components and circuit layout can be arranged on both sides of the PCB respectively, and the electrical connection of the circuits on both sides is achieved through vias (Vias). This structure greatly increases the functional density of the circuit board, allowing it to implement more circuit connections in a relatively small area.

Manufacturing process:

• Design and layout:Firstly, the PCB design is carried out through circuit design software, with wiring and component placement on both sides, and the position type of vias are planned at the same time.
• Drilling and electroplating: Drilling is carried out according to the design requirements, and electroplating is performed after drilling to form a via the circuits on both sides.
• Etching: Remove the excess copper foil to form the desired circuit pattern.
• Assembly and welding: After the components are installed, welding treatment is carried out, which can be done using surface-mount technology (SMT) or through technology (THT).
