In this embodiment, the first step is to provide a plurality of roots according to the step 50, and the present invention is the third embodiment of the invention. The plastic substrate 1〇〇/ φ^φ3°^^μi of the spherical end face 30 is obtained. , ^^^„ The brother's convex surface 100 is similar. Then, according to step 51, the Ϊ4 hole A is widely provided with 1 Γ ΐ = 2, and the above plurality of plastic substrates 3 are respectively inserted into the ί ίί 2, the plastic substrate 3 The aspherical end surface is exposed outside the radiant base 4 to form an array of plastic substrates. Thereafter, the sensitizer adsorbed on the surface of the plastic substrate is immersed in the ZnG 1 solution of the material (4): di-ZnCl The liquid 'so that the surface of the plastic substrate is uniformly distributed - ~ 丄 To prevent oxidation of zinc ions, some granules can be added to the solution. 趟:, night work, 5/§3 7 into metal conductive layer 31 ' The single-nozzle spray gun first mixes the silver; d;; f in the liquid ore chamber, and then sprays it evenly on the spherical end face 3〇, and quickly reacts to form a silver-plated layer, :Ϊ:! Conductive layer 31 (refer to the fifth Figure) Then, step 54 performs an electric 1*1, a fifth drawing, and provides an electroforming device 6, including an electroforming tank 60, soil 61 and a The power source 62 has a cathode 62 () and a cathode til. The electroforming tank 60 is provided with a predetermined amount of electroforming liquid, and the plastic substrate array of the bismuth-conducting layer 31 is placed in the electroforming tank 6 In the crucible, the anode + substrate 61 is connected, the cathode 6 22 is connected to the metal substrate of the plastic substrate 3, and a direct current of 2 to 15 A/dra2 is passed for electroforming; After electroforming for a period of time, an electroformed deposition layer 32 is gradually formed between the metal conductive layer 31 of the plastic knee substrate 3 and the metal substrate 61 by the metal orientation of the metal substrate 61; Casting layer 32 and 1273029 V.
