• Lab Industrial High-Temperature Aging Oven

  Nov 05, 2025

  An industrial high-temperature aging oven is a device that conducts accelerated aging tests on industrial products (such as electronics, electrical appliances, components, chemical materials, etc.) by simulating high-temperature environments. By applying high-temperature stress, potential defects and faults of the products can be exposed in advance, thereby screening out early-failed products and enhancing the reliability and stability of the products leaving the factory. Its core components mainly include the heating system, circulation system, control system and safety protection system.   Main features: Firstly, it has a wide operating temperature range, typically from room temperature +10°C to +200°C or 300 °C. Temperature uniformity is a key indicator for evaluating the performance of an oven. The temperature difference at each point inside the oven is ±2°C, and the temperature control accuracy usually reaches ±0.1°C to ±1°C, ensuring the precision and repeatability of the test conditions. In addition, the heating rate can be set according to the test requirements, ranging from linear heating to rapid heating. The internal structure of the test chamber is usually made of stainless steel (such as SUS304), which is heat-resistant and corrosion-resistant. The shell is generally made of high-quality cold-rolled steel plate and the surface is treated with plastic spraying. Finally, the insulation layer is usually made of high-density aluminosilicate cotton or rock wool, with sufficient thickness to ensure that the surface temperature of the box is low and energy-saving. The air duct is designed for horizontal or vertical air supply to ensure that the hot air can flow evenly through each product under test.   Aging ovens are widely used in all industries that have high requirements for product reliability: Electronics industry: IC chips, PCB circuit boards, power supplies, chargers, LED displays/lamps, automotive electronics, etc. Electric appliances: transformers, relays, capacitors, circuit breakers, motors, etc. Communication products: mobile phones, routers, base station equipment, optical modules, etc. Chemical materials: Conduct high-temperature aging resistance tests on coatings, plastics, rubbers, adhesives, etc. Automotive parts: various sensors, controllers (ECUs), wiring harnesses, etc.   How to choose the right industrial high-temperature aging oven? When making a choice, the following factors need to be comprehensively considered: 1. Temperature range: According to the product testing standards, select the model that can meet the highest and lowest temperature requirements, and leave a certain margin. 2. Inner box size: Select an appropriate volume based on the size and quantity of the products to be tested. Remember to reserve space to ensure air circulation. 3. Temperature uniformity and accuracy: The higher the requirements, the higher the equipment cost and manufacturing difficulty. Choose according to the strictness of the test. 4. Load condition: If the product will generate heat by itself during the testing process (i.e., "load testing"), it is necessary to inform the equipment manufacturer so that they can calculate and configure sufficient heating and heat dissipation capacity. 5. Control System and Functions: Is program control (multi-stage temperature rise and heat preservation) required? Is it necessary to record and export the temperature curve data? Whether remote monitoring and other factors are needed Industrial high-temperature aging ovens are an indispensable part of modern quality engineering. Through sample aging tests, it intercepts potential faulty products before they leave the factory, significantly reducing the market return rate and after-sales maintenance costs, and earning credibility and long-term benefits for the enterprise. When making a purchase, you can communicate fully with us based on the characteristics of your own products and testing requirements, and choose the most suitable solution.

• Lab Aging Test Chamber Working Principle

  Oct 17, 2025

  Many products (such as rubber, plastic, insulating materials, electronic components, etc.) will age due to the combined effects of heat and oxygen when exposed to the natural environment over a long period of use, such as becoming hard, brittle, cracking, and experiencing a decline in performance. This process is very slow in its natural state. The air-exchange aging test chamber greatly accelerates the aging process by creating a continuously high-temperature environment and constantly replenishing fresh air in the laboratory, thereby evaluating the long-term heat aging resistance of materials in a short period of time.   The working principle of Lab aging test chamber mainly relies on the collaborative efforts of three systems: 1. The heating system provides and maintains a high-temperature environment inside the test chamber. High-performance electric heaters are usually adopted and installed at the bottom, back or in the air duct of the test chamber. After the controller sets the target temperature (for example, 150°C), the heater starts to work. The air is blown through the heater by a high-power fan. The heated air is forced to circulate inside the box, causing the temperature inside the box to rise evenly and remain at the set value. 2. The ventilation system is the key that distinguishes it from ordinary ovens. At high temperatures, the sample will undergo an oxidation reaction with oxygen in the air, consuming oxygen and generating volatile products. If the air is not exchanged, the oxygen concentration inside the box will decrease, the reaction will slow down, and it may even be surrounded by the products of the sample's own decomposition. This is inconsistent with the actual usage of the product in a naturally ventilated environment. 3. The control system precisely controls the parameters of the entire testing process. The PID (Proportional-integral-Derivative) intelligent control mode is adopted. The real-time temperature is fed back through the temperature sensor inside the box (such as platinum resistance PT100). The controller precisely adjusts the output power of the heater to ensure that the temperature fluctuation is extremely small and remains stable at the set value. Set the air exchange volume within a unit of time (for example, 50 air changes per hour). This is one of the core parameters of the air-exchange aging test chamber, which usually follows relevant test standards (such as GB/T, ASTM, IEC, etc.).   The test chamber creates a high-temperature environment through electric heaters, achieves uniform temperature inside the box by using centrifugal fans, and continuously expels exhaust gases and draws in fresh air through a unique ventilation system. Thus, under controllable experimental conditions, it simulates and accelerates the aging process of materials in a naturally ventilated thermal and oxygen environment. The biggest difference between it and a common oven lies in its "ventilation" function, which enables its test results to more truly reflect the heat aging resistance of the material during long-term use.

  LEDとは何ですか？ 発光ダイオード（LED）は、順方向電圧を印加すると単色の不連続光を発する特殊なダイオードです。この現象はエレクトロルミネッセンスと呼ばれます。半導体材料の化学組成を変化させることで、LEDは近紫外線、可視光線、または赤外線を生成できます。当初、LEDは主に表示灯やディスプレイパネルに使用されていましたが、白色LEDの登場により、現在では照明用途にも使用されています。21世紀の新たな光源として認識されているLEDは、従来の光源に比べて高効率、長寿命、耐久性など、比類のない利点を備えています。 明るさによる分類： 標準輝度LED（GaP、GaAsPなどの材料で作られる） 高輝度LED（AlGaAs製） 超高輝度LED（その他の先進材料を使用） ☆ 赤外線ダイオード (IRED): 目に見えない赤外線を放射し、さまざまな用途に使用できます。   LED信頼性テストの概要: LEDは1960年代に開発され、当初は交通信号や民生用製品に使用されていました。照明や代替光源として採用されるようになったのは近年のことです。 LED 寿命に関する追加情報: LED 接合部温度が低いほど寿命は長くなり、逆もまた同様です。 高温下でのLED寿命: 74°Cで10,000時間 63°Cで25,000時間 LED光源は工業製品として35,000時間（保証使用時間）の寿命が求められます。 従来の電球の寿命は通常約 1,000 時間です。 LED街灯の寿命は50,000時間以上と予想されます。 LEDテスト条件の概要: 温度衝撃試験 衝撃温度1 室温 衝撃温度2 回復時間 サイクル ショック法 備考 -20℃（5分） 2 90℃（5分）   2 ガスショック   -30℃（5分） 5 105℃（5分）   10 ガスショック   -30℃（30分）   105℃（30分）   10 ガスショック   88℃（20分）   -44℃（20分）   10 ガスショック   100℃（30分）   -40℃（30分）   30 ガスショック   100℃（15分）   -40℃（15分） 5 300 ガスショック HB-LED 100℃（5分）   -10℃（5分）   300 液体ショック HB-LED   LED高温高湿試験（THB試験） 温度/湿度 時間 備考 40℃/95%RH 96時間   60℃/85%RH 500時間 LED寿命試験 60℃/90%RH 1000時間 LED寿命試験 60℃/95%RH 500時間 LED寿命試験 85℃/85%RH 50時間   85℃/85%RH 1000時間 LED寿命試験   室温寿命試験 27℃ 1000時間 定電流での連続点灯   高温動作寿命試験（HTOL試験） 85℃ 1000 時間 定電流での連続点灯 100℃ 1000 時間 定電流での連続点灯   低温動作寿命試験（LTOL試験） -40℃ 1000 時間 定電流での連続点灯 -45℃ 1000 時間 定電流での連続点灯   はんだ付け性試験 テスト条件 備考 LED のピン (コロイドの底から 1.6 mm 離れたところ) を 260 °C の錫浴槽に 5 秒間浸します。   LED のピン (コロイドの底から 1.6 mm 離れたところ) を 260+5 °C の錫浴槽に 6 秒間浸します。   LED のピン (コロイドの底から 1.6 mm 離れたところ) を 300 °C の錫浴槽に 3 秒間浸します。     リフローはんだ付け炉試験 240℃ 10秒   環境試験（TTWはんだ処理を240℃±5℃の温度で10秒間実施） テスト名 参照標準 JIS C 7021の試験条件の内容を参照 回復 サイクル数（H） 温度サイクリング 自動車仕様 -40℃ ←→ 100℃、滞留時間15分 5分 5/50/100 温度サイクリング   60℃/95%RH、通電時   50/100 湿度逆バイアス MIL-STD-883法 60℃/95%RH、5V RB   50/100
