pcb manufacturing Types

HDI PCB manufacturing
HDI PCBs are a type of multilayer PCB that utilizes advanced technologies to achieve higher circuit density and miniaturization. They incorporate microvias and high-density routing to accommodate complex and densely packed components.

Rigid-Flex PCB manufacturing
Aluminum PCB, also known as Metal Core PCB, is a type of printed circuit board that uses an aluminum base material. It possesses unique characteristics and application advantages compared to traditional substrate materials such as FR-4. The structure of a

Aluminum PCB manufacturing
Aluminum PCB, also known as Metal Core PCB, is a type of printed circuit board that uses an aluminum base material. It possesses unique characteristics and application advantages compared to traditional substrate materials such as FR-4.

Multilayer PCB manufacturing
Multilayer PCB (Printed Circuit Board) refers to a type of PCB that consists of multiple layers of conductive traces and insulating material stacked together. Unlike single-layer or double-layer PCBs, which have only one or two layers of conductive materi

Heavy Copper PCB manufacturing
Heavy Copper PCB refers to a type of printed circuit board that features a significantly thicker copper layer compared to standard PCBs. The copper thickness in heavy copper PCBs typically ranges from 3 ounces (105 micrometers) to 20 ounces (700 micromete
Materials needed for PCB production process
The materials needed in the PCB production process mainly include copper foil, photoresist film, corrosion agent, welding film, components and so on. Among them, copper foil is the basic material of the PCB board, the photoresist film is used to make the graphics and lines of the PCB board, the corrosion agent is used to etch away the excess copper foil, the welding film is used to protect the PCB board and the welding pad, and the components are an important part of the PCB board.Equipment needed for PCB production process
The equipment needed in the PCB production process mainly includes platemaking machine, etching machine, drilling machine, coating machine, welding equipment, testing equipment, cleaning equipment and so on. Among them, platemaking machine is used to make photoresist film, etching machine is used to etch off excess copper foil, drilling machine is used to drill, coating machine is used to cover welding film, welding equipment is used to install and weld components, testing equipment is used to detect PCB board quality, cleaning equipment is used to clean the welded PCB board.pcb manufacturing Why Choose Semshine
