PCBA (Printed Circuit Board Assembly) processing involves connecting various electronic components on a PCB board using techniques such as surface mount technology (SMT) and through-hole technology (DIP), along with other electronic assembly processes. The primary steps in the PCBA process include SMT, automated optical inspection (AOI), DIP, functional testing (FCT), and additional procedures. Given the size variability of electronic components, different assembly techniques and requirements are necessary for each type. The assembly density of PCBA tends to be high, and the compact size and light weight of electronic products yield specific challenges and requirements in mounting. Essential factors, such as reliability, seismic resistance, and excellent solderability, dictate high standards for both the hardware and software used in PCBA processing.

The term "stamp hole" in the context of PCBA processing refers to a connection method used within the main board interface. Small boards must be interconnected to facilitate laser cutting. These connections feature small round holes located on the ribs, resembling the pits found on the edges of commemorative stamps, which we refer to as stamp holes.

The Meaning of PCBA Processing Stamp Holes

The overall design of the stamp holes closely resembles the round hole pattern cut into commemorative stamps. One significant advantage of this method is that it offers better compressive strength compared to a V-Cut. Unlike Tap technology, which requires cutting with router machines, stamp holes can be easily separated. However, a drawback is that controlling the fracture surface can be challenging. If the distance between the lines is too small, it can easily lead to damage, resulting in additional costs.

In general, PCB assembly can incorporate either stamp hole technology or dual V-shaped groove cutting technology. When opting for stamp holes, it is crucial to ensure that the stained edges are evenly distributed around each component of the PCB assembly to prevent deformation during soldering due to uneven support. The stamp hole section should be positioned close to the inner side of the PCB to prevent residual burrs from harming the assembly line after separation in panel assembly. When selecting V-shaped grooves on both sides, it is important to control the depth of the groove to be 1/3 of the total thickness (the sum of both sides). Accurate groove specifications and symmetrical depth are essential for optimal results.
