1.Element shall be free from obvious contamination,deep scratches and metal deformation.

2.Tolerance of concentricity between metal disc and ceramic shall be within 0.5mm.
3.All solder points shall be prevented by the isolation glue.
4.Eccentricity of the inner circle and outer circle of metallic plate is 0.3.
5.Eliminate the leaning metallic part,up to ceramics part,to avoid the short circuit with the

metallic ringlet.
