Chip heating chemistry testing How does heating a chip work?

Date:2023-03-29 14:35:16Views:366

Chip heating chemistry testing is usually used to study the process and properties of chemical reactions. Usually, a heating chip is used as a heat source, and the reaction temperature is controlled through the heating chip to study the kinetics, thermodynamics, and other properties of the reaction. So, how is the heating chip made? This article summarizes some information and hopes to provide valuable reference for readers.

Common methods for chip heating chemistry testing:

Differential scanning calorimetry (DSC): Using a heating chip to heat the sample, measure the temperature difference between the sample and the reference material, and study the thermal properties of the sample, such as heat capacity, thermal decomposition temperature, etc.

Thermogravimetric analysis (TGA): Use a heating chip to heat the sample and measure the weight change of the sample to study the thermal stability, thermal decomposition, and other properties of the sample.

Dynamic Thermomechanical Analysis (DMA): Using a heating chip to heat the sample, while applying mechanical loads, measure the deformation of the sample to study the thermoelasticity, thermal expansion, and other properties of the sample.

Thermal Flow Analysis (TFA): Using a heating chip to control the reaction temperature and measure the heat flow changes during the reaction process to study the reaction kinetics and thermodynamics.

The manufacturing process of the heating chip:

Material selection: Select suitable resistance materials, usually using chromium alloy, nickel chromium alloy, and other metal materials.

Preparation of the bottom plate: The bottom plate is usually made of ceramic, quartz, and other materials, and then coated with a metallized layer.

Thin film preparation: The selected material is made into a thin film by physical or chemical methods and deposited on the bottom plate.

Graphical processing: Using photolithography technology to pattern the shape and size of the desired heating area onto a thin film.

Etching: Using chemical etching or ion beam etching to etch or etch away unwanted parts.

Electrode preparation: Prepare electrodes at both ends of the heating chip, usually made of metal.

Cleaning: Clean the surface of the chip to remove impurities and contaminants.

Test: Test the performance and function of the heating chip.

In summary, chip heating chemical testing is a common chemical testing method that can be used to study various chemical reactions and properties of materials, and has wide applications in materials research, drug development, chemical engineering, and other fields. Our company has a team of professional engineers and industry elites, and has three standardized laboratories with an area of over 1800 square meters. It can undertake various testing projects such as electronic component testing and verification, IC authenticity identification, product design and material selection, failure analysis, functional testing, factory incoming material inspection, and tape weaving.
