PE circuit board parts packaging trays play a crucial role in the storage of electronic components. Their core function is to prevent damage to components from impacts, static electricity, moisture, or environmental factors through a combination of physical protection and material properties.
The groove or grid design of PE circuit board parts packaging trays is the core of basic protection. By customizing precise positioning for each component, PE circuit board parts packaging trays restrict the movement space of components, preventing collisions caused by shaking during transportation or storage. For example, for components with delicate pins such as QFPs and BGAs, the edges of the grooves in the PE circuit board parts packaging trays are rounded to prevent sharp edges from scratching the component surface; for irregularly shaped components, PE circuit board parts packaging trays can achieve a tight fit by adjusting the grid shape, reducing gaps. Furthermore, partitions or anti-slip pads are often added between layers of PE circuit board parts packaging trays to further distribute pressure and prevent the lower layers of components from deforming due to the weight of the upper layers.
Electrostatic discharge (ESD) is the number one threat to electronic components, especially sensitive components such as integrated circuits and chips. PE circuit board parts packaging trays utilize conductive fillers or antistatic agents to maintain the surface resistance of the material within a safe range, thereby conducting static electricity to the ground or neutralizing it. For example, conductive PE circuit board parts packaging trays have a surface resistance below 10⁶ ohms, suitable for components extremely sensitive to static electricity; static dissipative PE circuit board parts packaging trays have a surface resistance between 10⁶ and 10⁹ ohms, suitable for general electronic components. This design effectively prevents static electricity buildup and component failure due to electrostatic breakdown.
The humidity, temperature, and chemical contamination of the storage environment directly affect the lifespan of components. PE material itself has excellent moisture resistance, preventing water vapor penetration and avoiding oxidation of component leads or thermal expansion of internal moisture leading to package cracking. In high-temperature environments, PE circuit board parts packaging trays require the use of PE formulations with strong temperature resistance to prevent material softening and deformation; in low-temperature environments, antifreeze agents must be added or pure raw materials must be used to prevent embrittlement and breakage. Furthermore, PE circuit board parts packaging trays often have an anti-corrosion coating to resist the erosion of acidic or alkaline gases or chemical solvents, ensuring stable performance over long-term use. The stacking method of PE circuit board parts packaging trays directly affects their load-bearing capacity and stability. When stacking empty PE circuit board parts packaging trays, the height should not exceed 1.5 meters, and supports such as shelf uprights or dedicated PE circuit board parts packaging tray racks should be provided on both sides to prevent collapse. PE circuit board parts packaging trays in use should be laid flat in a corner, away from aisles, to avoid collisions with forklifts. The shelf position of PE circuit board parts packaging trays storing parts should be selected according to weight; heavy items should be placed on the bottom shelf to lower the center of gravity, and lighter items on the middle shelf for easy access. If PE circuit board parts packaging trays are used for shelf storage, ensure that their deflection does not exceed 20mm to prevent parts from slipping due to deformation.
Impact during handling is a common cause of parts damage. When using forklifts or manual hydraulic pallet trucks, the forks must be fully inserted into the PE circuit board parts packaging tray's insertion holes to avoid impact to the sides; the fork depth should be sufficient, and the speed should be controlled below 2km/h to prevent the PE circuit board parts packaging tray from swaying. Plan the route before handling, avoiding ground obstacles and minimizing bumps. For irregularly shaped parts, gaps should be filled with foam or bubble wrap, or secured with ropes or straps to prevent displacement during transport.
Regular cleaning and inspection are key to extending the lifespan of PE circuit board parts packaging trays. PE circuit board parts packaging trays can be wiped with a soft, damp cloth. Stubborn stains can be cleaned by soaking in a specialized cleaner, but avoid using sharp tools such as steel wool to prevent scratching the surface. For long-term storage, PE circuit board parts packaging trays should be stored in a dry, cool place, avoiding direct sunlight to prevent aging. If outdoor storage is necessary, cover with a sunshade or tarpaulin to prevent UV-induced material degradation. Furthermore, regularly inspect PE circuit board parts packaging trays for cracks, deformation, or reduced load-bearing capacity, and replace damaged trays promptly.
PE circuit board parts packaging trays can be highly customized to meet the different sizes, shapes, and protection requirements of various parts. For example, shallower grooves can be designed for ultra-thin components to prevent pin bending; a bottom support structure can be added for heavy components to distribute pressure; and RFID tags can be added to high-value components for end-to-end traceability. This customized design maximizes the adaptation to component characteristics, enhances protection, and optimizes storage space utilization.
