CTE-360热膨胀系数测试仪 ANALISIS TECH  CTE-360 Thermal Expansion Tester   Analysis Tech

CTE-360 热膨胀系数测试仪  可在 -25°C 至 100°C 的温度范围内测量各种材料的热膨胀系数。 虽然主要用于研究电子封装应用中使用的材料，但它实际上可用于该温度范围内的任何固体、凝胶、糊状物或粘性液体。

测量线性和体积热膨胀系数的仪器也称为“热膨胀系数测试仪 ”。 Analysis Tech CTE-360 热膨胀系数测试仪 使用专门针对电子封装材料实施的 ASTM D696。 软件包 WinCTE 包含在测试仪中，并为测试控制、数据收集/分析和演示功能提供了一个简单的用户界面。 CTE 精度公差通常在 ±2% 到 ±8% 之间，尽管所有数据都会自动附加单独计算的公差。 CTE-360 热膨胀系数测试仪 是一种经济、独立、固态、独立的装置，不需要外部冷却器或制冷设备。

固体材料测试-样品通过直接插入圆柱形测试室进行测试。 它们可以是圆柱形或多边形，最大横截面尺寸为 0.5 英寸（12.5 毫米）以适合测试室。 名义上推荐的样品长度为 2 英寸（50 毫米），尽管这个长度并不重要，可以使用更短的样品。

The CTE-360 measures thermal expansion coefficients on wide range of materials over a temperature range of -25°C to 100°C.   Although intended primarily for the study of materials used in electronic packaging applications, it can be used on virtually any solid, gel, paste, or viscous liquid over this temperature range.

Instruments for measuring  linear and volumetric thermal expansion coefficients are also known as “dilatometers”.  The Analysis Tech CTE-360 Tester uses ASTM D696, specifically implemented for electronic packaging materials.  The software package, WinCTE, is included with the tester and offers a simple user-interface for test control, data collection/analysis, and presentation features.   CTE accuracy tolerances typically range from ±2% to ±8%  although all data is automatically appended with individually computed tolerances.  The CTE-360 Tester is an economical, self-contained, solid-state, standalone unit that requires no external chiller or refrigeration equipment.

Solid material test-samples are tested by directly inserting them into the cylindrical test chamber.  They can be cylindrical or polygonal with maximum cross sectional dimension of 0.5 inches (12.5 mm)  to fit into the test chamber.  The nominal recommended sample length is 2 inches (50 mm) although this length is not critical and shorter samples can be used.

Other material types may require specific sample holders:  solid sheet-like materials are tested using the Thin Sample Holder which measures thermal expansion in the XY (in-plane) direction. Viscous liquid materials, including phase change materials, are tested in the Liquid Sample Holder which includes disposable/reusable containment tubes.

The Analysis Tech CTE-360 Tester does not require any external coolant or temperature forcing equipment. The included control software WinCTE runs on any PC or lap top with USB interface and Windows 7 or higher operating system.

Data is recorded in text files, Excel format files, and a variety of graphical data plots.
