IPC-WHMA-620 Industry StandardThis is the appearance acceptance standard for cable assembly negotiated by the Cable Assembly Association and the Electronic Connection Products Committee. If there is no standard for process inspection and finished product inspection, IPC/WHMA-A-620 can be used as the inspection standard document for products alone. It specifies process control or defective products that allow repair/rework. This information suggests that it needs to be improved by statistical process control plan (refer to IPC-9191).   Although IPC/WHMA-A-620 is an industry standard, it does not cover all designs. However, it provides process standards for general products. If non-universal or special processes are used, a unique acceptance standard can be established. This unique acceptance standard should include customer requirements or promises, and should include acceptable standards for each feature. If possible, new standards or special standards for products should be submitted to the IPC Committee for standard improvement form, so that the IPC Committee can update the version.

The connector industry set a new sales record in 2022   Connection industry sales volume(2022) The connection device industry increased +7.8% in 2022, and global sales reached $84.1 billion US dollars. This is a new industry sales record. The following table shows the sales performance in 2022 according to the geographical area.   It is worth noting that North America achieved sales growth better than China in 2022. In fact, North America has performed better than China in the past five years. China may continue to exceed North America in terms of sales growth.       First of all, China's labor costs have risen, creating opportunities for other countries to compete in Western investment. Secondly, China's "zero -new crown policy" may lead to the closure of some companies.     The effect of currency and inflation The US dollar strongly strengthened in 2022, reducing the actual growth of the industry. Calculated in the US dollar, the industry has achieved +7.8% of sales growth, but the calculation of local currency has only achieved +2.0% growth. The following table explains this.   Considering that the global inflation rate between 2022 is between 8% and 10%, the industry implements prices in the same range. Measured by the unit, the connectioner industry may not grow.   As of the release, the financial performance of the year in 2022 has not been announced, but we believe that the rise in prices can offset the rise in raw materials and labor costs. Interestingly, we expect that the profitability of the connector in 2022 from good to excellent.     Healthy backlog of Connector in 2023  The preliminary voltage voltage order in 2023 was $ 22.983 billion or $14.8 billion weeks of sales. In 2021 years, the average sales of our quarterly sales were US $23.202.2 billion. Therefore, we should have enough backlog orders to achieve the flat or low -digit sales in the first quarter.     Please note that Amphenol and TE Connectivity predict that the first quarter of 2023 sales were -2.8% and -2.7%, respectively. Bishop forecast sales growth +0.5%. We believe that the industry may do better than these predictions, because: The results of Amphenol and TE are usually exceeded expected. The backlog is enough to grow in the first quarter.   The following shows the predictions of Amphenol, TE and the industry in the first quarter of 2023.    In the fourth quarter of the connector industry, sales increased +2.0%. This is lower than 2022 +7.8%, which indicates that demand is slowing. In addition, this trend is confirmed that amphenol has achieved +7.0% growth in the fourth quarter, while the whole year is +16.1%, and the fourth quarter of TE achieved +0.6% growth and +9.1% throughout the year. Both strong indicators indicate that the demand is slow. The forecast of Amphenol and TE's negative growth in the first quarter further proves the economic slowdown.   Consensus is t...

In 2020, China's automobile production will be 25.225 million units. It is estimated that the annual output value of China's automotive electronics wiring harness products will exceed 50 billion yuan with the price of 2,000 yuan per single wire harness. The development of automotive wiring harness industry is highly dependent on the automobile industry, and most of the brand car manufacturers have their own mature and stable automobile supporting system. In particular, international automobile enterprises represented by German, American and Japanese companies carry out strict assessment and evaluation on parts suppliers. Their long-term high standard requirements for parts make the combination of automotive wiring harness suppliers and automobile enterprises relatively stable. It is difficult to change the traditional supply chain of automobiles. In addition, the formulation of standards in the automobile field is crucial, and standards determine the market. In terms of the domestic market, most of the large self-owned auto manufacturers have local wiring harness factories with stable supporting production, while foreign-invested and joint-venture auto manufacturers have higher requirements for wiring harness. Most of the wiring harness manufacturers selected are wholly owned or joint ventures of international component manufacturers in China.   In recent years, as international automobile manufacturers pay more attention to cost control and the localized purchase of auto parts is increasingly strengthened, a number of excellent autonomous wiring harness enterprises have emerged in China. Through long-term accumulation of product technology and synchronous development experience, these high-quality local enterprises have significantly enhanced their overall strength, and gradually entered the supplier supporting system of international automobile manufacturers with timely and effective service and reliable product quality.     As the new energy vehicle（Electric vehicle）market is an emerging market, no matter international or local manufacturers have too many existing products to promote, so the strength of suppliers' research and development ability will determine their share in the new energy vehicle market. In the process of rapid development of new energy vehicles（EV）, wiring harnesses are one of the most important auto parts, mainly including EV car wiring harnesses, BMS wiring harnesses, Energy storage wiring harnesses,etc. as the new energy lithium battery is very unstable, battery management system (BMS) as the core technology plays a pivotal role. The BMS wiring harness is the most important and plays the role of the nerve center. In BMS wiring harness, there are many sensors besides wires. Vehicle batteries are new and cannot be done by traditional automakers (the supply chain system of traditional automakers is difficult to change). However, they have high requirements on wiring harness, which must be short,thin and ...

It is reported that recently, Jim Farley, the CEO of Ford Motor Company, said in an interview that the company has been continuously facing a shortage of rare earth magnets. This key material is crucial for car production, and the insufficient supply has forced one of its factories to temporarily suspend operations.   Jim Farley said that the supply of the key component, rare earth magnets, mostly comes from China. China has implemented a new approval process for rare earth exports, and this move continues to drag down the operation of the supply chain.   Image source: Ford Motor Farley admitted frankly, "The company is struggling to keep operating every day now." We have had to suspend some factories and can only barely hold on for now.   It is reported that due to the shortage of rare earth materials, Ford's Explorer SUV production line in Chicago was forced to suspend production for a week last month.   Farley said that he was pleased to note the progress made in the recent US-China trade negotiations, but emphasized that the supply situation of rare earth magnets has not yet seen a substantial improvement.   He said, "The company has submitted applications to the relevant departments in China and is currently reviewing them one by one." We are explaining to the (US) government and the Chinese leadership how important the jobs in the Midwestern United States that rely on the supply of rare earth magnets are. US President Trump said that a new round of negotiations with China recently reached an agreement, and China will promptly approve the export license for rare earths.   At present, rare earth materials have become a hot issue in the trade negotiations between the United States and China. This kind of scarce raw materials is widely used in automobiles, iphones and other products. Automobile manufacturers, especially those focusing on electric vehicles, are among the largest industrial consumers of rare earth materials. The production of core components such as windshield wipers, electric seats, audio systems, and electric vehicle motors all rely on rare earth materials. China is leveraging its dominant position in the global rare earth supply chain to hold significant bargaining chips in negotiations.   China controls over 90% of the world's rare earth processing capacity and implemented new export licensing rules in April, tightening supplies to Western manufacturers and affecting a wide range of products from automobiles, fighter jets to household appliances.   However, it was reported that China had issued temporary export licenses to rare earth suppliers of the three major US automakers, including Ford, earlier this month.     Aichie: Professional wiring harness solutions, connecting the intelligent future In the era of electrification and intelligence, reliable wiring harnesses are the key to the stable operation of equipment. Aichie is dedicated to the research and development and...

According to foreign media reports, British Prime Minister Keir Starmer recently announced that he will relax the mandatory rules for the sale of electric vehicles in order to ease the impact of the US tariff policy on the local auto industry. This policy adjustment may bring new market opportunities for Chinese auto parts enterprises, especially automotive wiring harness factories and supporting suppliers.   Core content of policy adjustment According to the latest document from the British Department for Transport, the new policy mainly includes three measures: 1. Extend the transition period for traditional fuel vehicles: Extend the sales period for hybrid vehicles from 2030 to 2035, and exempt Aston Martin, Bentley and other niche luxury brands from electric sales targets. 2. Lower emissions fines: The fine for vehicles that do not meet the latest emissions standards has been reduced from £15,000 to £12,000. 3. Increase infrastructure investment: £2.3 billion for charging network expansion and tax breaks for car purchases.   Analysts pointed out that this "flexible transformation" strategy is designed to win time for car companies to upgrade technology, and the expansion of supporting infrastructure will directly drive the demand for electric vehicle wiring harnesses, charging modules and other components. The wiring harness suppliers represented by China Aichie Tech are expected to become the preferred choice for the diversification of the supply chain of British car companies by virtue of their high cost performance and rapid response ability.   USA tariffs force a restructuring of European supply chains Starmer's administration has made it clear that the change is a response to the Trump administration's 25 percent tariff on imported cars. Although the UK faces a lower tax rate (10 per cent) than the EU and China, JLR has suspended exports to the US, exposing supply chain vulnerabilities. Notably, the UK's statement specifically emphasized the need to "strengthen global trade relations." This provides a strategic opportunity for Chinese automotive wire harness factories: Substitution effect: European car companies may accelerate the search for non-US supply chains, Chinese wiring harness companies account for 30% of global production capacity, technology maturity comparable to Europe and the US. Local cooperation: Companies such as Aichie Tech Manufacturing can circumvent tariff barriers by setting up joint ventures with UK charging operators. The competitive advantage of Chinese enterprises 1. Cost efficiency: The cost of high-voltage wiring harnesses for electric vehicles made in China is 20-30% lower than that in Europe and the United States, and has passed international certifications such as ISO 6722. 2. Customization ability: For the UK market, manufacturers such as Aichie Tech Manufacturing can quickly adjust the wiring harness specifications (such as right rudder model adaptation). 3. Technical coll...

Introduction "One kilometer per second", the anxiety about battery life is gradually becoming history. Liquid-cooled supercharging is rewriting the energy replenishment pattern of electric vehicles at an unprecedented speed, and the market spring is approaching. Under this wave of change, how should the automotive charging cable industry upgrade in line with the trend? After 600kW, the new 720kW full liquid-cooled supercharging architecture made a shocking debut. The first full liquid-cooled supercharging station in the world's port was officially put into use. The charging time was sharply reduced by half, and the supercharging efficiency achieved a qualitative leap. The secret of liquid-cooled supercharging lies in the liquid circulation channel between the charging gun and the cable. Driven by the power pump, the coolant circulates back and forth, efficiently absorbs heat energy, and allows the cable to run at low temperature throughout the process. Compared with traditional air cooling and natural heat dissipation, liquid cooling has the advantages of rapid charging, safe and worry-free, low noise, convenient and light, and has more advantages in operation and maintenance costs and service life, and has become the first choice for electric vehicle fast charging.   What is "liquid-cooled supercharging"? Liquid-cooled super charging technology is a new energy technology that applies a liquid cooling system to the charging process of electric vehicles. Its main principle is to cool the heat generated during the charging process through a liquid cooling system, thereby improving charging efficiency and speed. The liquid-cooled super charging system consists of a liquid-cooled charging gun (vehicle plug), coolant, liquid-cooled cable, cooling system (thermal management system, including a circulation pump, a liquid storage tank, a radiator, etc.), a charging gun core flow channel structure, a tail cable locking structure, and temperature control. The liquid-cooled super charging pile is a special liquid circulation channel set between the cable and the charging gun. The channel is filled with coolant that plays a heat dissipation role. The liquid cooling system efficiently takes away the heat from the charging cable, so that a larger charging current can be loaded on a thinner charging cable, which doubles the charging power and achieves the purpose of high-speed charging.   01 What are the requirements of liquid-cooled charging technology for cables? At the technical standard level, the 2024 Asian Cable Summit Forum provides guidance. At present, there are four modes for charging electric vehicles: Mode 1: The charging gun uses a common 16/32A single-phase or three-phase CEE plug for charging through a cable; Mode 2: An ICCB controller is added to Mode 1; Mode 3: Use a double-head charging gun to connect the car charging port and the AC charging pile; Mode 4: Use a DC charging pile for charging. Modes 1, 2, and 3 are AC slow charging, a...
