c******w

Much advanced quality inspection equipment is used in JT production. It is finely handled by the coordinate measuring machine (CMM), caliper, microcaliper, gauge, and pass meter.

l******n

JT is developed with a deep investigation. Its air circulation part, materials and layout of the interface with the device are all seriously considered by the R&D team.

i******l

JT is the outcome of combined theories. It is developed adopting the knowledge of heat convection, radiation, and conduction by the R&D department.

p******t

During the production of JT , the accuracy of machining and grinding, surface roughness, concentricity, and verticality are all strictly scrutinized to guarantee high quality.

v******a

Several key considerations for designing JT have taken into account, including heat resistance, fin arrangement, location of fins, fin efficiency, thermal interface materials, etc.

o******d

The product is corrosion resistant. Its materials will form a layer of oxidation film which features toughness and high density after an electrical process.
