We look forward to having in-depth exchanges with you and exploring more composite material application technologies and solutions.
The glue comes with precision microbeads, and the air gap is precisely controlled by the microbeads in thickness.
The CV value of microbead size is <3.5%, keeping the air gap consistent and uniform.
Microbeads have small tolerance, average diameter tolerance +/-2μm
Customized microbead size: 0.5 ~250μm
Optimize the effective magnetic flux to ensure the stability of the sensor;
Can correspond to various intervals;
Suitable for ferrite cores of various shapes;
No additional grinding or stirring is required in the process;
The SMT process can be integrated and solidified through reflow soldering, resulting in high production efficiency.
