Product Specification

Certificates – RoHS Test ReportWe achieved the RoHS Certificateissued by SGS for our VIP products.

Supertech VIP-SPEC

• Thermal conductivity( NPT) : Less than 0.0023W/m.K.• Density：≈300kg/m3

• Minimum size:100*100*6,Maximum size:1700*800*35• Dimension tolerance:Length:±7mm，Width:±5mm，Thickness：±1-1.5mm

• Lifetime：10-15 years ( We assume that VIP service lifeis supposed to end once its thermal conductivity exceeds0.01W/m.K.)

• At present, ordinary dessicant(made of Cao) is commonly used among mostof the VIP manufacturers. Dessicant can only absorb water molecule, but itis incapable of absorbing internal gas. And yet getter can and is able toguarantee a long VIP service life.

• Supertech, in possession of one getter and one high-performancedessicant(E-getter) production lines, is the only manufacturer that canindependently produce getters in China.

• Below are comparative tests on thermal conductivity variation of the VIPwith different getters.

2003—2013 Samples Preserved

• This is a sample chamber,where we have beenpreserving samples fortesting every year, everystage since 2003, and weview it as our treasurebecause of the abundantdata and messages itcarries. we stick toconducting repetitivetracking experiments everyyear.

• These samples have beenpreserved for 10 years, andit lays a firm and solid basisfor the theory of ST-VIPproduct life circle.
