Remark: Considering the difference between test spot and actual work spot, the impedance test condition is based on the whole working stroke. This is what we generally said dynamic impedance testing, it differs from the static test condition of ELA-364923, the durability test standard is also based on this test condition.
Equipped with comprehensive inspection and reliability testing equipment, great importance is attached to quality management of each link. This includes IQC, IPQC, 100% dynamic testing of spring force and contact impedance, 100% appearance inspection, FQC sampling inspection, CQC, design verification, regular reliability testing, failure analysis, and so on.
Strict and effective quality control has been implemented over each link which includes product design, sample preparation, trial production and mass production. As a consequence, our product quality is guaranteed.

Frequently Asked Questions (FAQ)
Q: What is the difference between dynamic impedance testing and static testing?
A: Unlike static testing (such as EIA-364923), the dynamic impedance test condition is based on the entire working stroke. This accounts for the difference between the test spot and the actual working conditions, which is also the basis for the durability test standard.
Q: What are the default plating specifications for the plunger and barrel?
A: Both the plunger and the barrel feature a standard plating specification of a 3 micro-inch minimum gold (Au) coating over 50 to 120 micro-inches of nickel.
Q: Can these components handle high-current and high-durability applications?
A: Yes. The products can support large currents of up to 15A and offer high durability, with configurations capable of achieving up to 1 million cycles.
Q: What quality management links are implemented during production?
A: Quality control spans the entire lifecycle: including IQC, IPQC, 100% dynamic testing of spring force and contact impedance, 100% appearance inspection, FQC sampling, CQC, design verification, regular reliability testing, and failure analysis.
Q: Are custom and non-standard structures available?
A: Yes. Non-standard structures can be fully customized according to specific integration requirements, including features such as special mushroom head structures.
Q: What are the mechanical and electrical ratings for standard models?
A: Standard electrical parameters include a maximum contact resistance of 100 mOhm, a maximum rated voltage of 12V DC, and a rated current of 1.0A. The standard mechanical life is rated at a minimum of 10,000 cycles.
