Talk about the baking and storage of PCBA and moisture sensitive components
Today I will talk to you about the baking and storage of PCBA and moisture-sensitive components. Do you know that the components processed by SMT must be baked before they can be used? Do you know how long it takes to bake the moisture-sensitive components processed by PCBA? How should they be stored in order to avoid problems such as moisture. Let's take a look with the electronic editor below.

1. Baking requirements for PCBA and moisture sensitive components

(1) All new components to be installed must be baked and dehumidified according to the moisture sensitivity level and storage conditions of the components in accordance with the relevant requirements in the "Specifications for the Use of Moisture Sensitive Components".

(2) If it is necessary to heat to above 110 degree Celsius during the repair process, or if there are other moisture-sensitive components within 5mm around the working area of the repair, it must be based on the moisture sensitivity level and storage conditions of the components in accordance with the relevant requirements in the "Specifications for the Use of Sensitive Components" Requires baking and dehumidification treatment.

(3) For moisture-sensitive components that need to be reused after repair, if hot air reflow, infrared, etc. are used to heat the solder joints through the component package, it must be based on the moisture sensitivity level and storage conditions of the components in accordance with the "Moisture Sensitive Components" The relevant requirements in the "Device Usage Specification" require baking and dehumidification treatment. For the rework process that uses a manual soldering iron to heat the solder joints, it is not necessary to pre-bake the moisture-sensitive components under the premise that the heating process is controlled.

2. Storage environment requirements for PCBA and components after baking

Baked moisture-sensitive components, PCBA, and unpacked new components to be replaced, once the storage conditions exceed the expiration date, they need to be re-baked. For the storage conditions of various levels of moisture-sensitive components, please refer to the "Specifications for the Use of Moisture Sensitive Components" Relevant requirements.

The above is the baking requirements and storage environment of PCBA and moisture-sensitive components. I will introduce you to this. You can follow Baiqiancheng Electronics, learn more about PCBA and learn more information.
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
