One-time film forming process for processing mobile phone cover plate coating film and mobile phone cover plate

The invention discloses a one-time film forming process for processing a mobile phone cover plate coating film. The one-time film forming process comprises the following steps that a coating film is subjected to air extraction and heated, the coating film vacuum degree meets high-temperature film coating requirements, then, a mobile phone cover plate is plated with an ITO film and an SIO2 film in the coating chamber, and therefore one-time film forming is achieved for the mobile phone cover plate. The one-time film forming process can meet the technological requirements for high efficiency, low cost, high transparency and the like. 本发明公开了种用于加工手机盖板镀膜的次成膜工艺，其包括有如下步骤：对镀膜室抽气、加热，使镀膜真空度达到高温镀膜要求，之后在镀膜室内对手机盖板镀制ITO膜和SIO2膜，以令手机盖板上次成膜。本发明可以满足高效率、本低成、高透光率等工艺要求。
