CTE-360熱膨脹系數(shù)測試儀 ANALISIS TECH ?CTE-360 Thermal Expansion Tester ? Analysis Tech

CTE-360 熱膨脹系數(shù)測試儀 ?可在 -25°C 至 100°C 的溫度范圍內(nèi)測量各種材料的熱膨脹系數(shù)。 雖然主要用于研究電子封裝應(yīng)用中使用的材料，但它實際上可用于該溫度范圍內(nèi)的任何固體、凝膠、糊狀物或粘性液體。

測量線性和體積熱膨脹系數(shù)的儀器也稱為“熱膨脹系數(shù)測試儀 ”。 Analysis Tech CTE-360 熱膨脹系數(shù)測試儀 使用專門針對電子封裝材料實施的 ASTM D696。 軟件包 WinCTE 包含在測試儀中，并為測試控制、數(shù)據(jù)收集/分析和演示功能提供了一個簡單的用戶界面。 CTE 精度公差通常在 ±2% 到 ±8% 之間，盡管所有數(shù)據(jù)都會自動附加單獨計算的公差。 CTE-360 熱膨脹系數(shù)測試儀 是一種經(jīng)濟、獨立、固態(tài)、獨立的裝置，不需要外部冷卻器或制冷設(shè)備。

固體材料測試-樣品通過直接插入圓柱形測試室進行測試。 它們可以是圓柱形或多邊形，最大橫截面尺寸為 0.5 英寸（12.5 毫米）以適合測試室。 名義上推薦的樣品長度為 2 英寸（50 毫米），盡管這個長度并不重要，可以使用更短的樣品。

CTE-360 Thermal Expansion Tester

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.
