标准摘要
[中文适用范围]： IEC 61189 的这一部分指定了一种测试方法，用于监测印刷电路板 (PCB) 中单个镀通孔 (PTH) 的电阻，以确定 PTH 在温度循环引起的热机械应力下的耐用性。 [外文原描述]： IEC 61189-3-719:2016 specifies a test method to monitor the resistance of single plated-through holes (PTHs) in printed circuit boards (PCBs) to determine the PTH durability under thermo-mechanical stress induced by temperature cycling.
英文名称Test methods for electrical materials, printed boards and other interconnection structures and assemblies - Part 3-719: Test methods for interconnection structures (printed boards) - Monitoring of single plated-through hole (PTH) resistance change during temperature cycling
