The circuit board on the PCB production line serves as the operational board. After all the printing processes are completed, it needs to be divided into smaller PCB boards efficiently and swiftly once the circuit board is formed. V-Cut is predominantly utilized for standard boards, whereas guide boards often employ stamp holes. Hollow connection strips are used in boards with very narrow panels, such as those requiring half-hole processing. This chapter primarily elaborates on three puzzle methods and distinguishes between them.
Also known as “V-CUT,” this method involves cutting a groove at the junction of two boards, where the connection is relatively thin and prone to breakage. During assembly, the edges of the two boards can be aligned, and the V-cut typically follows a straight line without complex traces like bending arcs. When implementing V-cut, ensure a straight line and maintain a gap between the boards, usually around 0.4mm. The V-cut line should be represented using 2D lines across all layers.
Since V-cutting is limited to straight lines, it is suitable only for panel connection of regular PCBs. For irregular PCBs, such as circular ones, stamp holes are required to facilitate panel connection.
It is another way of connecting the puzzle, generally used in the special-shaped plate, at the edge of the two boards through a small plate to connect, and this small plate and the connection of the two plates have many small holes, so easy to break, the reason why it is called “stamp hole”, because the edge of the board after breaking is like the edge of the stamp.
PCB stamp hole refers to a special hole located on the edge of the circuit board to fix and support the PCB board. Stamp holes usually consist of a pair of small holes that are connected to adjacent support points to provide a stronger holding force. This type of hole is common in PCB designs, especially in applications where circuit boards need to be mounted or connected.
The name stamp hole comes from its design that resembles a postage stamp. The design of the stamp holes allows the PCB board to be fixed more firmly on the chassis or frame and is not easy to bend or deform. The location and size of the stamp holes need to be designed according to the actual application to ensure the support and fixation of the PCB board.
The manufacture of stamp holes requires the use of specialized tools and techniques. During the production of circuit boards, stamp holes need to be drilled first, then sheet metal and pressed. The manufacture of stamp holes requires precise control and high-quality workmanship to ensure the accuracy and quality of the holes.
In PCB design, the design and layout of mounting holes must consider the overall structure and support requirements of the PCB. Designers should arrange these holes strategically based on practical application scenarios and mechanical structure demands to ensure the board’s fixation and stability.
The connection method resembles mounting holes, but with narrower strips and no vias on either side. This approach has a drawback: when the board breaks, there will be a noticeable bump. Mounting holes, on the other hand, tend to have less noticeable bumps due to the separation provided by vias. Why choose this method then? In situations where neither mounting holes nor V cuts are feasible — such as with a fully surrounded half-hole module — connections can only be made at the module’s four corners via hollow connecting strips.
