Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a storage method used for storing a PCB board. The method includes the following steps: storing the PCB board in a package; carrying out vacuum-pumping treatment on the package; filling the package with protective gas so as to isolate the PCB board from oxygen; and sealing the package so as to seal the protective gas in the package. Oxygen and water vapor in the package can be effectively removed by carrying out the vacuum-pumping treatment on the package. When the package is vacuum-pumped, the vacuum-pumped package is filled with the protective gas. Through the actionof the protective gas, the oxygen and water vapor can be completely discharged from the package, and the protective gas completely occupies the remaining accommodation space of the package. Finally,the package is sealed, and the protective gas is completely sealed in the package, thereby insolating the PCB board form oxygen and water vapor, and finally preventing the PCB board from being oxidized by oxygen and water vapor and scrapped.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a storage method. Background technique [0002] In the SMT (Surface Mount Technology, Surface Mount Technology) patch production process of terminal equipment such as mobile phones, PCB (Printed Circuit Board) boards need to be used. Generally, unused PCB boards are at risk of being oxidized after unpacking. Contents of the invention [0003] A technical problem solved by the invention is how to prevent the oxidation of the PCB board. [0004] A storage method for storing PCB boards, comprising the steps of: [0005] Store the PCB board in the package; [0006] vacuumizing the package; [0007] filling the package with protective gas to isolate the PCB board from oxygen; and [0008] The packaging body is sealed to seal the protective gas in the packaging body. [0009] In one embodiment, the protective gas is at least one of nitrogen, inert gas and hydrogen. [0010] In...
