In the field of precision electronic components and new material research and development, the performance of environmental simulation equipment directly determines the efficiency of product reliability verification. In August 2025, Yuchuang Precision Technology (Shenzhen) Co., Ltd. (hereinafter referred to as "Yuchuang Precision") and Guangdong Aipei Testing Equipment Co., Ltd. (hereinafter referred to as "Aipei Technology") reached an important cooperation and successfully introduced an AP-HX-50C3 50 liter constant temperature and humidity test chamber. This procurement not only injects high-precision testing capabilities into Yuchuang Precision's R&D system, but also becomes a typical case of the application of domestic environmental testing equipment in the field of precision manufacturing.

1、 Driven by technical requirements: Cracking the bottleneck of precision component testing

As an enterprise dedicated to the research and development of high-precision electronic components, Yuchuang Precision's products are widely used in the fields of 5G communication, new energy vehicles, and industrial automation. With the increasing demand for product weather resistance in the market, enterprises urgently need to solve two major testing challenges:

Insufficient accuracy in temperature and humidity alternating testing: Traditional equipment fluctuates in humidity up to ± 5% RH, resulting in a performance data deviation rate of over 12% for electronic components under temperature and humidity conditions, directly affecting the product certification pass rate.

The R&D cycle is lengthy: a single temperature and humidity cycle test takes 72 hours, and the equipment failure rate reaches an average of 8% per year, which restricts the iteration speed of new products.

In response to the above pain points, the Yuchuang Precision Technology team has focused on the core selection indicators after 3 months of market research:

Temperature range: -40 ℃ to+150 ℃, covering the entire temperature range

Humidity control accuracy: ≤± 2% RH

Equipment stability: Redundant design of core components, failure rate ≤ 3%

Response speed: Temperature change rate ≥ 3 ℃/min (no load)

2、 Technical Benchmarking: The Core Advantage of Aipei Technology Equipment

After comparing six domestic and foreign suppliers, the AP-HX-50C3 equipment from Aipei Technology stands out with four major technological highlights:

1. High precision environmental control system

The equipment is equipped with a French Taikang fully enclosed compressor and a Japanese Hitachi backup compressor, forming a dual system redundant architecture. Through the dew point temperature laminar contact dehumidification technology of evaporator coil, humidity uniformity of ± 2.0% RH is achieved, which is 60% higher than traditional equipment. The inner box is made of 304 stainless steel material, combined with polyurethane rigid foam insulation layer. In a low temperature environment of -40 ℃, the temperature fluctuation inside the box is only ± 0.5 ℃, which meets the MIL-STD-810G standard.

2. Intelligent program control

The 7-inch touch programmable controller supports 120 sets of programs and 100 complex experimental designs per set, and can simulate composite scenarios such as "high temperature and high humidity → low temperature and low humidity → temperature and humidity alternation". For example, Yuchuang Precision can set a testing process of "85 ℃/85% RH for 168 hours → -40 ℃ for 24 hours", and the data is transmitted in real-time to the LIMS system through the RS232 interface to generate a test report that complies with ISO 17025 standard.

3. Energy efficiency and safety design

Using DuPont R404A environmentally friendly refrigerant from the United States, combined with an internal spiral copper tube heat exchanger, energy consumption is reduced by 18% compared to imported brands. The equipment is equipped with six safety mechanisms including compressor high pressure protection, over temperature alarm, and leakage protection, and has passed CE and CNAS certification to ensure 24-hour continuous operation stability.

4. Fast delivery and localized services

Relying on the flexible manufacturing capabilities of the Dongguan production base, Aipei Technology completed equipment production and debugging within 12 working days after the contract was signed, shortening the industry average cycle by 45%. There are 12 after-sales service outlets established nationwide, providing 4-hour response and 24-hour on-site service, and regularly pushing software update packages to support device function expansion.

3、 Application effectiveness: Dual leap in R&D efficiency and product quality

Three months after the equipment was put into use, Yuchuang Precision achieved three major breakthroughs:

Shortened testing cycle: The time for a single temperature and humidity alternating test has been reduced from 72 hours to 48 hours, resulting in an overall 30% reduction in the research and development cycle.

Data accuracy improvement: The humidity control accuracy has been increased from ± 5% RH to ± 2% RH, and the test data has been directly certified by international organizations such as UL and T Ü V, with customers including top companies such as Huawei and BYD.

Cost optimization: Equipment energy consumption is reduced by 18% compared to imported brands, saving over 80000 yuan in electricity bills annually; The failure rate has decreased from an average of 8% per year to 1.5%, and maintenance costs have been reduced by 65%.

Taking a certain type of new energy vehicle high-voltage connector as an example, through the simulation of the "-40 ℃ to+125 ℃ rapid temperature change+85% RH humid and hot" scenario using Aipei Technology equipment, Yuchuang Precision successfully optimized the sealing ring material formula, increasing the product life from 5 years to 8 years and increasing the export value by 65% year-on-year.

4、 Industry Insights: The Rise of Domestic Equipment and Ecological Co construction

This procurement case reflects two major industry trends:

Domestic substitution acceleration: Local enterprises such as Aipei Technology have made breakthroughs in core technologies, branding in key indicators such as accuracy and stability, and prices are only 60% of imported equipment, becoming a technological upgrade for small and medium-sized enterprises.

Deepening Service Ecology: From equipment customization, rapid delivery to full lifecycle maintenance, the technical response speed and service closed-loop capability of suppliers are becoming the core considerations for customer decision-making.

As stated by the R&D Director of Yuchuang Precision, "Aipei Technology not only provides a device, but also builds a full chain testing platform covering R&D, production, and quality inspection." This technology empowerment and ecological synergy model is driving China's precision manufacturing towards higher reliability standards.
