Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and in particular to a circuit board positioning device. Background Technology

[0002] Printed circuit boards (PCBs), also known as circuit boards, are important electronic components. Traditionally, circuit boards were created by printing resist onto the surface to create circuit diagrams and drawings, hence the name "printed circuit board." Currently, most circuit boards are mounted on an adhered resist layer (layered or coated), and etching can only proceed after exposure and development.

[0003] During PCB electroplating, positioning devices are needed to hold the boards in place and prevent them from loosening and falling off during the plating process. However, most positioning devices can only position PCBs of one size. Positioning devices that can accommodate very large boards cannot adequately accommodate standard or smaller boards, resulting in poor versatility.

[0004] Therefore, this utility model provides a circuit board positioning device that can accommodate various different types of circuit boards to solve the problems mentioned in the background art. Utility Model Content
