热阻分析仪Phase 11主要用于二极管、三极管、线性调压器、可控硅、LED、MOSFET、MESFET、IGBT、IC等分立功率器件的热阻测试和分析。

二、Analysis Tech Phase 11 Phase10工作原理及测试过程Phase 11采用油浴法测定热敏参数校正曲线。

在通以感应电流结还没有明显产生热量时，如果给定足够的时间，结温和壳温将达到热平衡，壳温非常接近结温。

将热电偶直接连接到器件表面采集数据时，油浴将充分保证器件的温度稳定并且使热电偶采集的温度等于感应结温。

在这个环节中，感应电流大小的选择是很重要的。

感应电流过大，会导致结温明显变化；感应电流过小，会导致正向压降值测量误差较大。

Phase 11 感应电流的可选范围是0.1mA~50mA，完全符合JEDEC标准。

在加热器件的过程中，Phase 11 采用了脉冲加热方式，如下图所示：加热电流和感应电流通过电子开关切换的方式轮流工作。

每加热15秒，测量1次热敏参数，即获得1个结温值，测量完之后继续加热，加热15秒，再次测量结温值，如此反复工作。

在这个过程中，系统将每次测量到的结温值和前面7个结温值进行比较，如果连续8个结温值相同，系统会判定器件达到热平衡，并计算出稳态热阻值。

如果用户需要得到热阻热容曲线，只需要将电子开关锁定在测量端即可。

此时，因为没有了加热电流，器件开始降温，通过监测器件电压可以得到一条温度下降的曲线，进而通过一系列数学变换得到热阻热容曲线以及瞬态热阻抗曲线。

In multiple-die packages, the die-to-die heating (thermal cross-coupling) must be measured to accurately characterize these type of packages. For testing functional integrated circuits (ICs), multiple sense junctions offer validation of the junction temperature (Tj) readings in instances where some of the Tj sense connections are subject to the spurious electrical effectsof other portions of the IC circuitry. When testing hybrids and large-die ICs, multiple sense junctions canreveal temperature distributions that occur when substantial temperature variations exist within the test device. Multiple sense channel applications include:▪Multi-die devices where multiple heat sources may exist▪Thermal cross-coupling associated with multi-chip devices▪Larger devices which may exhibit substantial temperaturegradients during normal powered operationMultiple sense channels also permit the calibration of up to 8 sense junctions simultaneously for faster calibration through-put.Batch Mode and Bin Sorting for Power Pulse TestingAccurate and rapid screening of device thermal characteristics can dramatically enhance production-device reliability. Die Attachment testing provides an excellent gauge of the chip attachment-quality in terms of the device impedance. The Phase 11 Thermal Analyzer provides programmable relay drivers for controlling external devices during Power Pulse Testing. These drivers offer the following capabilities:▪switching between test points in hybrid circuit test fixtures for multiple sequenced tests▪manual or automatic handler controls bin sorting based on die attachment test resultsThe test switching capability of the Thermal Analyzer allows one test fixture to carry all the test connections or test-point probes for a batch of tests required for testing complex hybrids. Thus all significant die attachments on a hybrid can be tested with one insertion and one test initiation.Bin sorting is utilized in die attach testing to rapidly sort devices based on die-attachment quality. The bin sorting control can be used with manual insertion testing or with automatic component transfer systemswhich would insert devices to be tested into test fixtures and subsequently eject the tested device into oneof up to eight bins. (see Die Attach Testing in Production Environments)Accessory Equipment Control PortsFrequently, device thermal performance must be evaluated over a range of external conditions.
