Description

Technical Field

[0001] This utility model relates to the field of PCB board processing, specifically to a wear-resistant printing base. Background Technology

[0002] During the PCB manufacturing process, printing is required on the PCB to achieve the desired effect. PCB printing is typically performed on PCB printing equipment. This equipment includes a printing base and a printing press. During printing, the PCB is transferred to the printing base, which supports and secures the circuit board. The printing press then moves to the PCB to adhere to it and perform printing, achieving the desired effect.

[0003] Existing printing bases mainly use aluminum alloy structures. As we know, aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the lightweight metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific alloy properties due to the different types and amounts of alloying elements added. However, aluminum alloy bases do not have corrosion resistance. Therefore, this invention is hereby applied for. Utility Model Content
