Why can ESD plastic trays protect electronic products?

Raw materials for ESD plastic pallets

ESD electronics plastic trays are typically made from the following materials:

Conductive plastic: This material directs static charges to the ground, preventing them from building up on electronics.

Antistatic additives: These additives reduce the surface resistivity of a material, making it more likely to conduct electricity.

Other materials: Other materials, such as reinforcing fibers or flame retardants, are sometimes added to make the pallet stronger and more durable.

Production of ESD plastic pallets

The manufacturing process of plastic trays for ESD electronics products typically includes the following steps:

Mixing materials: Mix conductive plastics, antistatic additives and other materials in proportions.

Molding: The mixed material is injected into the mold and formed into the desired shape.

Cooling: Cool the mold to room temperature and remove the tray.

Inspection: Check the pallet for defects or damage.

The role of ESD plastic trays

The primary purpose of ESD electronics plastic trays is to protect electronics from electrostatic discharge (ESD) damage. ESD refers to the charge transfer phenomenon that occurs when a charged object comes into contact with another object. During the manufacturing and transportation of electronic products, ESD can cause damage to electronic components and even cause fires or explosions.

ESD electronics plastic trays protect electronics in the following ways:

• Conductive: The tray’s conductive material directs static charges to the ground, preventing them from accumulating on electronics.
• Isolation: Trays isolate electronics from other conductors, reducing the chance of ESD occurring.
• Cushioning: The tray absorbs the energy of collisions and impacts, protecting electronics from physical damage.

The protection principle of ESD plastic trays for electronic products is based on the following aspects:

• Faraday Cage Effect: The Faraday Cage Effect means that when a charged object is placed in a metal cage, the charge will be distributed on the surface of the cage, while the charge inside the cage is zero. ESD Electronics Plastic Trays treat electronics as a Faraday cage, shielding them from electrostatic fields.
• Charge Transfer: The conductive material of ESD electronics plastic trays directs static charges to the ground, preventing them from building up on electronics.
• Charge Dissipation: ESD electronics plastic trays provide a low-impedance path that allows static charges to dissipate quickly.

ESD Electronics Plastic Trays are an important tool for protecting electronics from ESD damage. They effectively prevent static charges from accumulating on electronic products by conducting, isolating, and buffering, thereby reducing the risk of ESD.
