What is the benefits of stamp hole design in ZYNQ 7010 Core Board?

1. Efficient production and assembly

The small-sized stamp holes enable multiple small-sized PCBs to be assembled onto the substrate for mass production. They can be easily separated by simply snapping or cutting, significantly enhancing production efficiency and reducing costs. 

2.Modular design is flexible

In high-density PCB design, the small-sized stamp holes allow for the quick assembly and disassembly of independent modules (such as sensors, power management, etc.), facilitating maintenance and upgrades. 

3.Stress dispersion and reliability

The circular or elliptical hole design of stamps can avoid stress concentration during plating, reduce the risk of damage to circuits and components during plating, and improve the flatness of the edge of the board. 

4 Electrical performance guarantee

The small-sized stamp holes are designed with a reasonable spacing (usually 1.5-3mm), which not only ensures the stability of current transmission but also prevents solder short circuits or poor component contact. It is suitable for high-precision circuit connections.
