summary

The interface protection of electronic products needs over-voltage protection devices, and many engineers realize that protection devices are needed. However, due to improper selection or failure to follow the design principles of protection circuit PCB, the electrostatic test or EMC test of the products failed, and the products were repeatedly verified and tested, wasting manpower and financial resources, which always caused the products to be delayed in the market or over-designed, resulting in cost pressure. Leimao Electronics provides EMC design services for customers, provides laboratories to do bottom-up tests, and completes the design with high efficiency and convenient cost control, hoping to do our best for more customers to quickly pass EMC projects and improve product reliability. Leimao Electronic emc lab provides free testing and reference circuits for peripheral electrostatic protection. Leimao test equipment is available for customers to test for free.
