About failure reason
Reliability
Features of our thermoelectric cooler (module)

There are 4 main failure reasons for thermoelectric cooler (module)
1. Thermal cycle fatigue
2. Corrosion
3. Migration
4. Crystal failure of thermoelectric element
Our solutions are
GL structure
Moisture proof sealing
Complete quality control
To enable the long life by above. In addition, only the products passed our standard reliability test can be in our product lineup.

Solution by GL structure for "Thermal Cycle Fatigue"
Generally, thermoelectric cooler (module) is constructed by soldering (the alloy of tin and the lead) between cooling ceramic and cooper electrode, cooper electrode and thermoelectric chip, cooper electrode and heat released ceramic. However, our thermoelectric cooler (module) is using no solder but flexible resin glue between cooling ceramic and cooper electrode. This decreased thermal stress and enabled long life dramatically. We call this structure as GL (Glue=Adhesive) structure.

Solution by moisture proof sealing for "rust", "breaking", "short"
Our thermoelectric cooler (module) has passed various temperatures switching test, on/off test, and etc. by very good results. In different environments, you can use our high reliable product without anxiety.

Quality control is completely done to prevent "chip crystal failure"
Our company is not importing and selling our maker's products. We are a manufacturer to sell our produced thermoelectric cooler. Thermoelectric coolers (modules) are made based on strict quality control system. As a manufacturer, we own plenty of knowledge and technique, so we can reflect customer's needs on products.

About Chinese maker made thermoelectric cooler
We are frequently asked about quality of thermoelectric cooler (module) made by Chinese maker. Based on our test result, high quality products from Chinese maker are currently (2006) not capable of enough performance and quality to reach the level of acceptance.
