Metal-covered PCB with side wall grooves

Technical Field

The utility model belongs to the technical field of PCBs, and particularly relates to a metal-clad PCB with side wall grooves.

Background

PCB (printed circuit board), a printed wiring board, is one of the important components of the electronics industry. Almost every electronic device, as small as an electronic watch, a calculator, as large as a computer, a communication electronic device, a military weapon system, has only electronic components such as an integrated circuit, and a printed board is used for electrically interconnecting the respective components. The printed circuit board consists of an insulating base plate, connecting wires and bonding pads for assembling and welding electronic elements, and has the dual functions of a conductive circuit and the insulating base plate. The wiring device can replace complex wiring, realizes electric connection among elements in a circuit, simplifies assembly and welding work of electronic products, reduces wiring workload in a traditional mode, and greatly lightens labor intensity of workers; and the whole volume is reduced, the product cost is reduced, and the quality and the reliability of the electronic equipment are improved. The printed circuit board has good product consistency, can adopt standardized design, and is favorable for realizing mechanization and automation in the production process. Meanwhile, the whole printed circuit board subjected to assembly and debugging can be used as an independent spare part, so that the whole machine product can be conveniently exchanged and maintained. At present, the printed wiring board has been extremely widely applied to the production and manufacture of electronic products.

In the related art, along with the development of the market, the structural design requirements on the PCB board are also more and more diversified, and the PCB board is usually provided with through holes to communicate with the circuit layer, but when the side surface of the PCB board needs to be grooved, short circuit is easily caused.
