Embodiment 1
[0036] A production process for a double-plate laminated mobile phone backplane, comprising the following steps:
[0037] Step 1, preparing the composite ply, the preparation of the composite ply comprises the following steps:
[0038] Step 101, screen printing LOGO: silk screen printing LOGO layer on the composite board;
[0039] Step 102, UV transfer: transfer the first target texture in the transfer mold to the outer surface of the composite sheet through a UV transfer process to form a first texture layer;
[0040] Step 103, electron gun coating: setting the electron gun device to perform electroplating on the first texture layer to form a first coating layer, the first coating layer is an indium film layer;
[0041] Step 104, printing varnish: printing a layer of varnish on the first coating layer to form a varnish layer to obtain a composite plate;
[0042] Step 2. Bonding: Vacuum bonding the varnish layer on the composite board layer and the PC board through the trans...
Embodiment 2
[0051] The difference between the process of Example 2 and Example 1 is that the double-plate laminated mobile phone back plate prepared in Example 2 is sequentially from the inside to the outside: a rubbing texture layer with a thickness of 10 μm, a composite plate with a thickness of 0.38 mm, a thickness of The LOGO layer is 2μm, the first texture layer is 9μm thick, the first coating layer is 200nm thick, the PC board is 0.125mm thick, the transparent color layer is 10μm thick, the second texture layer is 7μm thick, the thickness It is a 30nm second coating layer and a 30μm cover ink layer.
Embodiment 3
[0053] The process of Example 3 is different from that of Example 1 in that: the double-plate laminated mobile phone back plate prepared in Example 3 is in order from the inside to the outside: a rubbing texture layer with a thickness of 18 μm, a composite plate with a thickness of 0.38 mm, a thickness of The LOGO layer is 1μm, the first texture layer is 11μm thick, the first coating layer is 450nm thick, the PC board is 0.125mm thick, the transparent color layer is 6μm thick, the second texture layer is 11μm thick, the thickness It is the second coating layer of 100nm and the cover ink layer with a thickness of 35μm.
