The design requirements and technical control of electronics packaging

The distinguishing feature of electronic products is their vulnerability to collision, compression, humidity, high temperature, and electrostatic hazards. Therefore, the packaging process design for electronic products should focus on these basic requirements and adopt corresponding technical measures for control.

Given that most electronic products are precision industrial products, the packaging design should consider the ability to withstand a certain degree of external force impact and collision during transportation, handling, and storage, to prevent damage to the housing or components. It should also be able to resist external forces or mutual compression between packaging boxes during stacking or transportation, to prevent deformation of the packaging or the product. The packaging should be able to resist moisture from fog, dew, rain, and steam, effectively preventing oxidation, rusting, and short circuits in the electronic products. It should also have good anti-radiation performance, be able to withstand sunlight without absorbing heat, and prevent deformation or damage to the product housing or components. Additionally, it should effectively suppress vibrations and friction generated during transportation and handling, to prevent electrostatic damage or accidental fire hazards to the electronic products.

In the daily production process, defects in the packaging design are not uncommon, such as when the placement of the overlapping tongue on the side of the paperboard box is on the front side during die-cutting design. This causes the cover latch tongue to collide with the overlapping tongue when the box is assembled, and the uneven thickness of the overlapping tongue also creates obvious gaps on the side near the overlapping tongue. Therefore, during die-cutting and layout, the overlapping tongue on the side should be designed to be on the same side as the cover latch tongue, ensuring that the overlapping and latch areas do not interfere with each other and preventing the formation of obvious gaps after assembly.

Additionally, the appropriate design of the overlapping tongue length is crucial for the performance of the packaged product. If the overlapping tongue length is too short, it is easy to cause adhesive overflow and mutual adhesion during gluing and bonding, and the insufficient overlapping tongue length can also significantly reduce the bonding and overall strength of the paperboard box, affecting the performance of the packaging. Generally, the overlapping tongue length of small paperboard boxes should not be less than 1.2 cm, and the overlapping tongue length of cartons should not be less than 2.6 cm, to ensure adequate bonding strength and improve the functionality of the packaging.
