In the die-cutting process we conduct in our daily work, our understanding is limited to knowing the product structure, material, name, and applicable range of the die-cut parts being processed. However, we are not clear about the classification and functional use of die-cut products.

When a mobile phone is disassembled, what die-cut parts do we know about? In the disassembly of electronic digital products, we may only be aware of a few die-cut parts within the digital product, without understanding all the supplemental functional devices. Therefore, in the process of receiving orders, we are unclear about what we can do and what we can do only partially.

Here, this article provides a preliminary classification of the terminal usage functions of die-cut parts, in the hope of providing enlightenment for engineers who are about to engage in die-cut processing and enter this industry.

Generally speaking, the classification of die-cut parts and accessories is mainly carried out from two aspects. The first aspect primarily categorizes die-cut parts and accessories based on the application of the main materials, while the second categorizes die-cut parts based on their terminal functions. In terms of die-cut parts in the common processing range of 3C electronic accessories, the die-cutting classification mainly includes the following aspects:

>>>>

Functional accessories for protection and cleaning

Local back glue protective film accessories

Protection film processing accessories

Enhancing light diffusion accessories

Function: In the production process of components such as mobile phones or optoelectronic modules, these accessories protect and clean the products or components, reducing the need for cleaning. Common functional accessories for protection and cleaning include touch screen protective film and inner protective film for the camera.

Functional accessories for conduction/insulation

Conductive fabric/conductive adhesive accessories

Conductive foam/insulation foam accessories

Insulation adhesive accessories

Function: To achieve isolation/connection and insulation/conduction between electronic components, in order to prevent short circuits and faults between adjacent components. Common functional accessories for conduction/insulation include PC sheets, PET sheets, insulating paper, Mylar sheets, insulating tapes, conductive fabric, and conductive adhesive.

Functional accessories for shielding

Shielding electronic accessories

Absorbent silicone rubber shielding accessories

Absorbent material accessories

Function: To isolate and eliminate the interference of electromagnetic waves on other electronic components, thereby controlling the effect of electric fields, magnetic fields, and electromagnetic waves from one area to another, affecting the normal operation of the electronic components.

>>>>

Functional accessories for brand protection

Mylar protective film handles

Double-label printing accessories

Label hanging accessories

Function: To achieve functions such as dust prevention, scratch resistance, anti-glare, and explosion protection. If the content printed can also serve as identification, promotion, and guidance, these accessories are usually used on various surfaces of mobile phones and their electronic components. Common examples include lens protection film, camera protection film, battery cover protection film, and screen explosion-proof film.

>>>>

Silk screen labels, nameplate accessories

Silk screen panels, button accessories

Nameplate Mylar

Nameplate back glue accessories

Function: To indicate and explain the brand, model, performance parameters, country of origin, warnings, and anti-counterfeiting measures of a product, usually used on the exterior of the product. Common examples include electronic labels and functional nameplates.

>>>>

Reinforcement and structural functional hardware accessories

Hardware components

Function: Widely used in FPC flexible circuit boards to address the problem of insufficient mechanical strength of flexible circuit boards, increase the strength of plug-in positions, and facilitate the overall assembly of products. They can also achieve the function of induction and conduction.

Packaging box accessories

PC packaging box accessories

Compared with traditional paper boxes, plastic boxes are environmentally friendly, non-toxic, have high transparency, and provide a more intuitive display of the packaged products, effectively enhancing the packaging grade of the products. Common products include packaging plastic boxes made of PET, APET, and PP materials.

The above categorization and functional accessory classification are specific to electronic accessories for mobile phones in the die-cutting industry. In our daily work processes, we can focus on the various functions provided by these accessories to understand their operating characteristics, their characteristic requirements, and their use standards. This will facilitate a clear understanding of the operational requirements and specific knowledge of die-cutting processes, thus avoiding production inertia and facilitating problem-solving.

Meanwhile, in the entire die-cutting industry, there are many other classifications for die-cut parts, such as the classification of magnetic material functional accessories in the field of wireless charging, the classification of medical adhesive bandages and labels in the medical industry, and the classification of common accessories in daily chemical packaging. In the subsequent common knowledge, we will gradually popularize these classifications. Let's look forward to it together.
