Brief Introduction to Electronics Industry

The electronics industry is a vast global enterprise that consists of numerous distinct divisions. Among them, the business-to-business e-commerce sector, which involves the all-pervasive payment and telecommunications technology utilized for transactions between enterprises, is the largest. This particular sector alone recorded sales of $29 trillion in 2017.

The tech industry, consumer electronics, the semiconductor industry, and power electronics are also other prominent sectors within the electronics industry. In these various sectors of the electronics industry, some of the most commonly fabricated components are transistors, capacitors, semiconductors, diodes, and circuit chips. Popular products, composed of multiple electronic components, include computers, televisions, radios, and smartphones.

Top 3 Applications of CNC in the Electronic Industry

The extensive and diverse array of applications, coupled with the exceptionally high precision that CNC machining offers, make it an extremely valuable manufacturing technology for the electronics industry. CNC machines possess the capability to process not only conductive and non-conductive metals but also an extensive spectrum of plastics.


One of the most salient and significant benefits of this advanced technology is its remarkable speed. CNC machining can be effectively employed to manufacture electronic components within a relatively brief period. There is no need for a tooling stage before commencing production, and this technology does not encounter the quality limitations and constraints that are typically associated with additive manufacturing. Designs can be promptly and efficiently iterated and modified by utilizing CAD software. Moreover, once the toolpaths have been precisely determined by the computer and/or the machinist, only minimal manual operation is required.


A considerable number of electronics manufacturers have a strict demand for precise tolerances for their complex internal components. In such cases, CNC machining is frequently regarded as the most suitable and appropriate technology for fulfilling these exacting requirements.


  • Watch Manufacturing

CNC machining has impacted the way timepieces are crafted, elevating precision and quality to unprecedented levels.

1. Watch Cases

One of the primary areas where CNC technology shines in watch production is in the creation of watch cases. The intricate designs and precise specifications of watch casings require advanced machining capabilities that traditional methods may struggle to achieve. CNC machines excel in this aspect by precisely carving out watch cases from various materials such as stainless steel, titanium, or precious metals with remarkable accuracy and repeatability.


2. Watch Components

Moreover, CNC machining is instrumental in producing the internal components that drive the functionality of a watch. From intricate gears and escapements to delicate hands and indices, CNC technology enables manufacturers to fabricate these tiny yet critical parts with micron-level precision. This level of accuracy is essential for ensuring the proper functioning and longevity of the timepiece.


3. Decoration & Customization

Additionally, CNC technology allows for the customization and personalization of watches to meet the unique preferences of customers. Whether it involves engraving intricate patterns on watch dials or creating bespoke watch components, CNC machines offer the flexibility and precision required to bring personalized designs to life.

From crafting intricate watch components with unparalleled precision to enabling customization and enhancing production efficiency, CNC machining has become an indispensable tool in the creation of high-quality timepieces that define the artistry and precision of watchmaking.


  • Mobile Phone Manufacturing

As can be seen from the above picture, in a mobile phone, many parts need to be processed by CNC, such as the phone's casing and circuit board. Let's introduce in detail how these several parts are processed.


CNC-Advancements-in-the-Electronic-Sector-03.jpg 


4. Mobile Phone Casing

With people's increasingly strong demands for the appearance and hand feel of mobile phones. Therefore, more demanding requirements have been put forward for the design and processing of mobile phone casings, and the difficulty of selling products will also be greater. Let's first compare the differences between the processing methods of modern mobile phone casings and traditional ones:


Processing type

Material

Processing method

Characteristics

Traditional processing

Mainly plastic

Injection molding, etc.

Low cost, simple structure, and shape

Modern processing

Silicone, glass, metal, etc.

Mold opening, CNC precision milling

High cost, good texture, high precision

 

As can be seen from the above picture, traditional mobile phone cases were manufactured for practical purposes, with few considerations given to factors such as the product's weight and hand feel. In modern processing, there are very high requirements for the texture, appearance, and quality of mobile phones. Let's now talk about the technology and methods of CNC processing for mobile phone cases.


① First, analyze the processing technology based on the drawing of the casing.

② Mold the product according to the analyzed processing technology.

③ Obtain the blank made by the mold and make the corresponding fixtures.

④ Use the fabricated dedicated fixtures to process the blank samples.

⑤ Initially inspect whether the processed parts can meet the requirements of the drawing.

⑥ If they do not meet the requirements, corresponding adjustments need to be made to the mold or fixtures until they meet the requirements of the drawing.

⑦ Perform post-processing procedures (including surface treatment and polishing, etc.) on the processed workpieces that meet the drawing requirements.

⑧ Submit the finished product to the demanding department for verification of the finished product. Only after verification is passed can mass production be carried out.


The above is the processing method of mobile phone cases analyzed based on modern mobile phones. In actual processing, it is still necessary to analyze which processing method should be used for processing based on the specific drawing and customer requirements.


5. Circuit Board

Circuit boards are ubiquitous in all electronic devices. They are employed to make circuits more miniaturized and intuitive, and they exert a crucial role in the mass production of fixed circuits as well as the optimization of the layout of electrical appliances. Just envision, if circuit boards did not exist, a mobile phone would necessitate numerous dense wires for connection. Moreover, there would be no designated location to fix the processor and other components within the mobile phone. The thickness of the mobile phone would be extremely thick, and its functions would also be highly limited and simplistic.


During the processing of circuit boards, CNC is predominantly utilized for operations such as drilling and milling the shape.

  • Computer Manufacturing

In the field of computer manufacturing, there are even more parts processed by CNC, including motherboards, and input and output terminals. CNC processing is involved. For example, computer motherboards require CNC for drilling and processing corresponding screw holes and via holes, and they must be precisely consistent with the holes on the motherboard; otherwise, problems such as the motherboard not being able to be fixed in the chassis or not being installed properly will arise.

Among input and output devices, including keyboards, mice, monitors, speakers, etc., there are also many parts processed by CNC among them. For example, various holes in keyboards and mice, monitor stands, frames, connection holes of speakers, speaker fixing frames, etc. Some customized computer cases are not made through traditional sheet metal blanking, bending, and welding but are processed by CNC. Although the cost of CNC processing is relatively high, the appearance and heat dissipation characteristics of such products have been pursued by the majority of DIY enthusiasts.


In laptops, the ABC shells of laptops are generally processed through molding, but after the molding is completed, CNC is still needed to process the net size, including holes, shapes, and the processing of the molding surface. The purpose of molding is to reduce time and increase efficiency for the subsequent CNC processing. CNC processing is to obtain the size we need more accurately to ensure that various spare parts can be precisely installed in the corresponding positions. In addition to the shells, CNC processing is also used for heat dissipation modules, power supply modules, etc.
