7 tips: Avoid cracking when producing PCB boards
2024-08-14
To prevent PCB board cracking, the following measures can be taken:
1. Reasonably select the plate material and thickness: Select the appropriate plate material and appropriate thickness according to the application needs and mechanical strength requirements. Thicker sheets generally have better strength and bending resistance.
2. Good layout design: In PCB layout design, pay attention to avoid concentrating components with excessive weight or mechanical stress to reduce the concentration of mechanical stress on the board. Reasonably distribute components and balance the layout to reduce the impact of mechanical stress.
3. Control the thermal expansion of the board: The PCB board will thermally expand when the temperature changes, and different materials have different thermal expansion coefficients. In the layout design, the thermal expansion coefficients of different materials are taken into consideration and the difference in thermal expansion between different materials is minimized to reduce the stress on the board.
4. Strengthen connection methods: Strengthen the design of connection points, such as using pins, sockets, locking screws and other fixed connection methods to improve the reliability and tensile strength of the connection.
5. Control the manufacturing process: During the PCB manufacturing process, strictly control the temperature and humidity conditions to avoid excessive soldering temperatures and excessive hot and humid environments. Follow the manufacturer's recommendations and best practices to ensure the manufacturing process meets process requirements.
6. Pressure distribution: Pay attention to the pressure distribution of the PCB board during installation and use. Avoid excessive bending, excessive squeezing or excessive twisting of the PCB board to reduce stress concentration.
7. Testing and quality control: Carry out necessary testing and quality control during the PCB manufacturing process to ensure the quality and reliability of the PCB board. Identify potential cracking issues through quality control measures such as X-ray inspection, AOI (automated optical inspection) and mechanical strength testing.

About the development trend of automobile electricity
2024-08-06
The PCB industry is gradually picking up steam, and the sector continues to be active. Wind data shows that the share prices of leading companies such as Shanghai Electric Co., Ltd., Shennan Circuit (002916.SZ), Pengding Holdings, Shengyi Electronics (688183.SH), and Shenghong Technology (300476.SZ) have all increased by more than 50% since the beginning of the year ... Among them, the cumulative increase of Shenghong Technology reached 110%.
Automotive electronics is one of the recovery forces. Automotive electronics is a downstream application field that has seen rapid growth in recent years.
From 2022 to 2027, the global average annual compound growth rate of PCB output value is approximately 2%, of which the server/data transmission sector has a growth rate of 6.5% and the automotive sector has a growth rate of 4.8%.
PCB is the core component of automotive electronic control systems. The continuous increase in the penetration rate of autonomous driving and new energy vehicles will bring about structural demand for automotive PCBs.
Self-driving taxis require a large number of sensors, lidar and other electronic equipment to achieve intelligent control, which will increase the amount of PCB used. If self-driving cars are fully rolled out in the future, it will be a large incremental market for PCBs.
When a self-driving vehicle encounters a risky situation, the lidar must transmit the signal to the "main brain" of the vehicle at a very fast speed and take braking measures. When the signal is transmitted on the PCB, the signal layer must be insulated from the outside. There will be inductance and impedance between layers, as well as between lines, which will cause signal distortion. The solution is to use PTFE materials with better performance to replace the traditional epoxy resin plus glass cloth materials to achieve superior transmission performance. ...
The company's automotive electronic PCB products are indirectly used in electronic equipment such as radars, sensors, antennas, and vehicle-mounted satellite positioning and navigation systems in the vehicle-road-cloud collaborative system; Shenzhen South Circuit also regards automotive electronics as one of the key areas of expansion of its PCB business. It is reported that the company focuses on new energy and ADAS, and mainly produces high-frequency, HDI, rigid-flex, thick copper and other products. Among them, the proportion of products in the ADAS field is relatively high, which is used in cameras, radars and other equipment.
It is understood that the amount of PCB used in new energy vehicles is approximately 4-5 times that of traditional fuel vehicles. Automotive electronic PCBs have extremely high requirements for reliability and require rigorous testing and verification for up to 1-3 years before they can be certified as qualified suppliers by auto parts manufacturers.
Under the trend of electrification, networking and intelligence in the automotive industry, more and more automotive chips are used, and the requirements for circuit board integration and design accuracy have also increased significantly. For example, the manufacturing process of PCB boards for autonomous driving is generally relatively complex, and the market The price and profit margin are relatively high, which can help Chinese PCB companies achieve transformation and upgrading.

PCB industry status and forecast
2024-07-12
1. PCB manufacturing industry gradually moves to mainland China
The PCB industry is widely distributed around the world and was dominated by developed countries in the United States, Europe, and Japan in the early days. Before 2000, the United States, Europe and Japan accounted for more than 70% of global PCB output value. However, in the past two decades, Asia, especially China, has attracted the transfer of global electronics manufacturing due to its advantages in labor, raw materials, policies and industrial clusters. Mainland China, Taiwan, South Korea and other places are gradually becoming new manufacturing centers. Since 2006, mainland China has surpassed Japan and become the world's largest PCB production base, marking a change in the industrial competition landscape. The proportion of PCB output value in mainland China to the total global PCB output value has increased from 8.1% in 2000 to 54.6% in 2021.
In 2023, the total revenue of the top ten domestic PCB listed companies will reach 140.046 billion yuan. Among them, Dongshan Precision has the largest revenue volume, with revenue reaching 33.651 billion yuan in 2023. The second largest company is Pengding Holdings, with revenue in 2023 reaching 32.066 billion yuan.
2. The market will enter a new growth cycle, and China’s PCB industry will continue to develop healthily.
The size of the global PCB market will shrink in 2023 due to destocking pressure and interest rate hikes to curb inflation. According to Prismark data, global PCB output value will drop 15% year-on-year to US$69.517 billion in 2023. However, as market inventory adjustments, weak consumer electronics demand and other issues enter the final stage, as well as the accelerated evolution of AI applications, PCB will enter a new growth cycle. It is expected to increase by about 5% year-on-year in 2024, and the utilization rate of PCB manufacturers is expected to rebound. . In the medium to long term, the global PCB industry will usher in a revival. It is expected that global PCB output value will reach US$90.413 billion in 2028, with a compound growth rate of 5.4% from 2023 to 2028. China's PCB industry continues to develop healthily. In 2023, mainland China's PCB output value will be US$37.794 billion, accounting for more than 50% of the global market share.
PCB inventories are gradually being digested and the industry is recovering moderately. Taiwan's PCB sector revenue reached NT$23.7 billion in January 2024, with month-on-month growth picking up at 10%, showing that the PCB industry is currently in a moderate recovery stage.
From an inventory perspective, PCB manufacturers' inventories have gradually decreased since 2022Q1, and destocking has basically ended. The industry may have entered the replenishment stage starting from 2023Q3.
