Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit boards, in particular to a surface treatment device for a printed circuit board. Background Art

[0002] Printed circuit boards (PCBs), also known as printed circuit boards, provide electrical connections for electronic components. They can be categorized by the number of layers, including single-sided, double-sided, four-layer, six-layer, and other multi-layer boards. PCB production requires surface treatment of the copper surface. Since copper surfaces are easily oxidized in normal environments, making them impervious to tinning (poor solderability), they are protected by methods such as HASL (Highly Anti-Smudge Soldering), ENIG (Electronic Ingot), Immersion Silver, Immersion Tin, and Organic Solder Preservatives (OSP). Regardless of the protective method used, the copper surface of the substrate must be cleaned and derusted using acid, alkaline, and water washes before treatment. After cleaning, the board surface must be dried. Since the board is flat, it needs to be constantly flipped to achieve the best drying effect. Therefore, a surface treatment device for the board that ensures effective drying without manual flipping is proposed. Utility Model Content
