The SPD produced by the customer’s original supplier could not perform well. Because there was no jig when soldering the low-temperature trip point, the solder brand was changed at will; and the same temperature solder was used when soldering the low-temperature trip point of Type 1, Type 1+2, Type 2, and Type 3 SPDs, resulting in premature or late tripping, and even failure to trip.

Corresponding Solution
We use customized jigs when producing surge protectors, select high-quality well-known brand solder, and use solder of corresponding temperature for different types of SPDs.
Results
During the experimental test, our surge protectors can reach the standard value.
