1. Full metal-clad housing, resistant to EMI/ESD electrostatic interference
The whole metal shell enclosure structure provides excellent shielding performance and electrostatic discharge capability, effectively preventing high-frequency interference and instantaneous electrostatic breakdown, thereby improving the overall electromagnetic compatibility of the device.
2. Multi-point metal reinforced solder feet, resistant to plug-pull peel force
The shell sides and bottom extend with multi-point reinforced solder feet, forming a strong soldered fixation with the PCB, effectively dispersing lateral pulling and plug-pull shear stress, protecting the circuit board pads from tearing.
3. Bottom positioning pin design, precise and error-proof for automated placement
The bottom features dedicated positioning pins that precisely align with the PCB positioning holes during placement, preventing displacement or cold solder joints caused by molten solder surface tension during reflow, ensuring high placement yield.
