According to Hengyuan desiccant, electronic components are very susceptible to moisture during packaging and transportation, which can easily cause short circuits and burning. Therefore, moisture prevention for electronic components is particularly important. So what are the hazards of moisture to electronic components? And how to prevent moisture? Let Hengyuan desiccant share with you below.

What are the hazards of humidity to electronic components? At Hengyuan Desiccant It is understood that electronic components are extremely susceptible to moisture during packaging and transportation, which can easily cause short circuits and burnout. Therefore, moisture prevention for electronic components is particularly important. So what are the hazards of humidity to electronic components? And how to prevent moisture? Below, Hengyuan Electronic desiccant will share some information with you.

　　1. LCD devices: Although the glass substrates, polarizers, and filter films of LCD devices such as liquid crystal displays are cleaned and dried during the production process, they will still be affected by moisture after cooling, reducing the product's qualification rate. Therefore, after cleaning and drying, they should be stored in a dry environment with less than 40%RH, and desiccants can be used during packaging.

　　2. Other electronic devices: centralized resistance furnaces, capacitors, ceramic devices, connectors, switches, solder, PCR, IC, LED, SMD, wafers, quartz oscillators, SMT patches, electrode material adhesives, electronic pastes, high-brightness devices, etc., are all susceptible to moisture damage.

　　3. Electronic devices during operation: semi-finished products between packaging and the next process; before and after PCB packaging until power-on; IC, BGA, PCB, etc. that have been unsealed but not yet fully used; devices waiting for tin furnace soldering; devices that have been baked and are waiting to return to room temperature; unpackaged finished products, etc., are all susceptible to moisture damage. Therefore, professional electronic dehumidifying cabinets are needed to strictly control the humidity of the air in workshops and warehouses to achieve the optimal relative air humidity standards required for electronic component workshop production and warehouse storage.

　　4. If finished electronic machines are stored in a high-humidity environment for a long time, it will lead to malfunctions. For computer motherboards, CPUs, etc., it can cause oxidation of gold fingers, leading to poor contact and failure. The production and storage environment humidity for electronic industrial products should be below 40%. Some types of electronic products require even lower humidity. Moisture-proof Desiccant can be used to protect it from moisture.
