The utility model also has following embodiment; Said connection section is " U " shape structure; Opening that should " U " shape structure upwards is fastened on the graphite frame as bayonet socket and constitutes on the framework in space, and the gap reduces between edge and the framework of the silicon chip on the hook portion so that be placed on; The scope in said gap is 0.5~1.5mm.Reduced the gap between silicon chip edge and the framework effectively, so improved obviously that silicon chip is occurred when plated film around the plating phenomenon.
As the utility model preferred embodiment, said hook point is the plate body shape, and said connection piece is near said hook portion setting.
The utility model can be done further improvement, and said hook point is for being made into integration.
The framework in the said formation of the utility model space is a square, and said hook point is provided with two respectively on the horizontal stripe of framework.
Improve further as the utility model, the termination of said connection section is provided with the lug that makes things convenient for the anchor clamps clamping.
Compared with prior art, the utlity model has following significant effect:
(1) the utility model can effectively reduce the gap between silicon chip and the framework, and can control this gap minimum size is about 0.5mm, obviously improve that silicon chip is occurred when plated film around the plating phenomenon.
(2) the utility model is because most advanced and sophisticated usefulness as support, therefore silicon chip film-coated after, the most advanced and sophisticated vestige that stays on its surface is minimum, can not influence the outward appearance of silicon chip.
(3) the utility model is rational in infrastructure, makes to reduce sheet and fragment phenomenon when silicon slice placed is placed on it, improves the silicon chip quality, and easy to operate.
