Technical Description:
Board surface: 316L stainless steel, surface finish: 2R (Ra0.30-0.50um), there should be no micro-cracks and no obvious scratches or scratches on the board surface, and no deformation such as unevenness, delamination, etc. is allowed.
The flatness of the board surface is less than or equal to $1.5mm, the plumbness of the board surface: the error at the bottom of the board surface is less than or equal to 3mm, and the difference between the diagonal lines is less than or equal to $1.5mm.
Conductive rod (steel-copper composite rod): The conductive rod is clad with copper, the copper is T2 electrolytic copper, and the steel is 316L stainless steel.
The center line of the conductive rod coincides with the surface of the board, and the perpendicularity (drape) of the board surface and the conductive plane of the conductive end is +3mm; the parallelism of the two conductive planes of the end of the conductive rod is $0.5mm.
The bottom milling "V°-shaped groove is opened, and the conductive beam and the stainless steel plate are fully welded by fully automatic laser on both sides.
