1.Core customization requirement analysis
1.1 The standard box size or load-bearing capacity (such as automotive parts, large unmanned aerial vehicles, and entire cabinet servers) cannot meet the requirements. Special sample racks, trays or suspension devices are required. The test samples need to be powered on and run inside the box, and connected to cables or pipes (such as battery pack charge and discharge tests, engine component tests). Oil stains, particulate matter or corrosive gases may be released during the sample testing process.
1.2 It needs to be connected with mechanical arms and AGV carts to achieve automatic loading and unloading. The heating and cooling rates required far exceed the standard specifications (such as >15°C/min).
1.3 The equipment needs to adapt to specific room sizes, door opening sizes or floor heights. There are special requirements for the power supply (if it cannot meet 380V) and the cooling water source (if a cooling tower cannot be provided).
2. Key customized technical specifications
2.1 Customized Dimensions
The internal effective space is determined entirely based on the size and quantity of the customer's samples. The minimum distance between the sample and the box wall needs to be considered to ensure uniform airflow. It is necessary to clearly define the size of the door, the material of the sealing strip, the door lock mechanism (mechanical lock, pneumatic auxiliary lock), and the size and quantity of the observation window. The inner box is usually made of SUS304 stainless steel. The outer box body can be made of high-quality steel plate with plastic spraying or SUS304. For corrosive tests, more durable materials should be specified. Test holes are used for leads. The size, quantity and position of the hole diameters (such as left or right) need to be customized, and sealing plugs or flanges should be provided.
2.2 Confirm the test interval
The technical index standards for temperature are usually from -70°C to +150°C. The standard heating and cooling rate is 1 to 3°C/min. Linear rapid temperature change: 5 to 10°C/min. Nonlinear rapid temperature change: Customizable to 15°C/min or even higher. This is directly related to the power configuration of the refrigeration and heating systems and is a key factor influencing the cost. Customize stricter control accuracy, such as uniformity ≤±1.0°C and fluctuation ≤±0.5°C.
2.3 Refrigeration System
Air cooling: Suitable for sites where the ambient temperature is not high and the ventilation around the equipment is good.
Water cooling: It is suitable for large cooling capacity, high heat generation samples, or situations with high ambient temperatures. It is more efficient but requires a cooling tower.
Cascade refrigeration: It is used for low-temperature requirements below -40°C and usually adopts two-stage cascade.
2.4 Installation Method
The refrigeration system of the integrated machine is located at the top or bottom of the box, with a compact structure and convenient installation. The split-type refrigeration unit is separated from the box body and is suitable for high-power equipment. It can discharge noise and heat to the outside, but the installation is complex.
2.5 Control System and Software
The controller customizes the size and brand of the color touch screen, supports multi-segment programming, program group loops, step jumps, etc. Customized LAN interface for connecting to the upper computer (computer) for data monitoring and recording. Whether it is necessary to support remote network monitoring and operation, as well as customize record intervals and storage capacity.
2.6 Independent sample over-temperature protector.
Compressor overheat, overcurrent and overpressure protection; Fan overcurrent protection Cooling water cut-off protection and automatic stop test function when the door is opened; Leakage or short-circuit protection; Sound and light alarm prompt.
Customizing double-door temperature test equipment is a systematic project. The key to success lies in the clarification and refinement of the initial requirements. A detailed and unambiguous "Technical Requirements Document" serves as the cornerstone for communication between equipment suppliers and customers. It ensures that the final delivered equipment fully complies with testing, process, and site requirements, avoiding subsequent disputes and cost overruns.
The core function of adding nitrogen input in industrial ovens is to create an inert atmosphere environment with low oxygen or no oxygen. This is usually referred to as "nitrogen protection" or "nitrogen-filled baking".
Preventing oxidation is the most common and primary purpose. When heated in the air (with an oxygen content of approximately 21%), many materials will undergo oxidation reactions, thereby affecting product quality. Adding nitrogen input to industrial ovens can prevent the formation of oxide scale (such as rust) on the surface of metal products during heating, keep the metal bright and clean, and improve the quality of subsequent processes such as electroplating and spraying. Or to prevent the oxidation of component pins, pads and precision films at high temperatures, ensuring the quality of soldering and the long-term reliability of the product. At the same time, it can also prevent chemical and powder materials from undergoing chemical reactions with oxygen at high temperatures, thereby altering their chemical properties.
2. Some materials pose a risk of fire or explosion in high-temperature and oxygen-rich environments. Increasing nitrogen input can suppress combustion and explosion.
In industries such as printing and coating, a large amount of flammable organic solvents (such as alcohol, acetone, and toluene) are volatilized during the baking process. Introducing nitrogen to reduce the oxygen concentration below the limit oxygen concentration can completely eliminate the risk of fire and explosion, which is an important safety measure. For metal and plastic powders, when they reach a certain concentration in the air, they are highly prone to explosion when exposed to open flames or high temperatures. Nitrogen protection can create a safe processing environment.
3. Improve process control and product quality. Heating in an oxygen-free or low-oxygen environment can avoid many side reactions caused by oxygen. In processes such as chip manufacturing and solar cell production, extremely high cleanliness and an oxygen-free environment are essential to prevent the oxidation of silicon wafers, metal electrodes, etc., ensuring extremely high product yield and performance.
4. While filling the oven with nitrogen, the air that originally contained moisture and oxygen inside the oven will also be "driven out". This not only prevents oxidation but also plays an auxiliary drying role, making it particularly suitable for products that are extremely sensitive to moisture.
In conclusion, adding nitrogen input to industrial ovens is to actively control the heating environment rather than passively heating in the air. This is an important technical means used in high-end manufacturing and precision processing.
Internal environmental conditions
Benchmark cleanliness: At the beginning of the test, the chamber must reach the highest cleanliness level it claims (such as ISO Class 5 / Class 100). This is the premise of all tests. Before the test, the oven needs to run a long period of "self-cleaning" until the particle count shows that the concentration is stable below the standard for multiple consecutive times.
Temperature and Humidity: Although the oven is a heating device, its initial state needs to be clearly defined. The initial environment for testing is usually normal temperature and humidity, for example, a temperature of 20±5°C and a relative humidity of 30-60% RH. This is crucial for testing the heating time and temperature uniformity. If the process has requirements for the dew point of the environment, it may be necessary to record the initial absolute humidity.
Airflow state: The test should be conducted under the specified airflow pattern, typically in a vertical or horizontal laminar flow state. The fan must operate at the rated speed, with stable air pressure and air volume.
Test load: The test is divided into two conditions: no-load and full-load. No-load is the benchmark test for equipment performance. Fill the effective working space with a fully loaded simulated load (such as metal, pallets, etc.) to simulate the harshest working conditions. Full-load testing can truly reflect the impact of products on air flow and temperature fields in actual production.
External environmental conditions
1. The cleanliness level of the external environment must be lower than or equal to the cleanliness level designed by the oven itself. For instance, when testing an oven of Class 100, it is best to do it in a room of Class 1000 or cleaner. If the external environment is too dirty, it will seriously interfere with the measurement results of the internal cleanliness of the oven when opening and closing the door or when water seeps through gaps.
2. The laboratory requires a stable temperature and humidity environment. It is generally recommended to conduct the test under standard laboratory conditions, such as 23±2°C and 50±10% RH. Avoid testing in extreme or highly volatile environments.
3. The test area should be free of strong convective winds and it is best to maintain a slight positive pressure to prevent external contaminants from entering the test area.
4. The power supply voltage and frequency should be stable within the range required by the equipment.
5. The equipment should be placed on a ground or base with less vibration. There are no large stamping equipment, fans or other strong vibration sources around.
When testing a dust-free oven, controlling the external environment is as important as measuring the internal environment. An unstable, dirty or strongly interfering external environment can lead to distorted test data and fail to truly reflect the performance of the equipment. All test conditions should be clearly recorded in the final verification report to ensure the traceability and repeatability of the tests.

Burn-in Chamber
A burn-in chamber is an environmental oven used to evaluates the reliability of multiple semiconductor devices and performs large capacity screenings for premature failure (infant mortality). These environmental chambers are designed for static and dynamic burn-in of integrated circuits (ICs) and other electronic devices such as laser diodes.
Selecting Chamber Size
The chamber size depends on the size of the burn-in board, the number of products in each burn-in board, and the number of batches required per day to meet production requirements. If the interior space is too small, insufficient space between parts results in poor performance. If it is too large, space, time and energy are wasted.
Companies that are purchasing a new burn-in set-up should work with the vendor to ensure the heat source has enough steady-state and maximum capacity to match the load for the DUT.
When using forced recirculating airflow, parts benefit from spacing, but the oven can be loaded more densely vertically because airflow is distributed along the entire side wall. Parts should be kept 2-3 inches (5.1 – 7.6cm) from the oven walls.
Burn-in Chamber Design Specs
Temperature Range
Depending on the requirements of the Device Under Test (DUT) select a chamber that has a dynamic range such as 15°C above ambient to 300°C (572°F)
Temperature Accuracy
It is important that the temperature does not fluctuate. Uniformity is the maximum difference between the highest and lowest temperatures in a chamber at a specified setting. A specification of at least 1% setpoint for uniformity and 1.0°C control accuracy is acceptable in most semiconductor burn-in applications.
Resolution
A high-temperature resolution of 0.1°C will provide the best control to meet burn-in requirements
Environmental Savings
Consider a burn-in chamber that has a refrigerant that has a zero ozone layer depletion coefficient. Burn-in chambers with refrigeration are related to chambers operating in temperatures below 0 degrees Celsius down to – 55°C.
Chamber configuration
The chamber can be designed with card cages, card-slots, and access doors to simplify connecting DUT boards and driver boards with ATE stations.
Chamber Air Flow
In most cases a forced convection oven with recirculating airflow will provide the best distribution of heat and significantly speeds the time-to-temperature and heat transfer to parts. Temperature uniformity and performance depends on a fan design that directs air to all areas of the chamber.
The chamber can be design with a horizontal or vertical airflow. It is important to know the direction of inserting the DUT based on the airflow of the chamber.
Custom ATE Wiring
When it comes to measuring over hundreds of devices, inserting wires through an aperture or test hole may not be practical. Custom wiring connectors can be mounted directly to the oven to facilitate the electrical monitoring of the device with an ATE.
How A Burn-in Oven Controls Temperature
The burn-in oven uses a temperature controller executing a standard PID (proportional, integral, derivative) algorithm. The controller senses the actual temperature value versus the desired setpoint value, and issues corrective signals to the heater calling for application ranging anywhere from no heat to full heat. A fan is also used to equalize the temperature through the chamber.
The most common sensor used for accurate temperature control of the environmental oven is a Resistance Temperature Detector (RTD) which a platinum-based unit typically referred to as a PT100.
Sizing The Chamber
If you are using an existing oven, basic thermal modelling based on factors such as the oven’s thermal capacity and losses, heat-source output, and DUT mass will allow you to verify that the oven and heat source are sufficient to reach desired temperature with a thermal time constant short enough for tight loop response under the controller’s direction.
