1.3性能的分级与分型 1.3.1 分级 本规范对电路板在终端用途性能方面会产生一些变异的情形已有所认知，在IPC-6011（电路板性能检验之概述性规范）中已将电路板按其性能分成三种“性能级别”（即Class 1，2，3）。1.3.2 板型 无镀通孔（TYPE 1）及有镀通孔（TYPE2～6）的电路板其等型别可区分如下：TYP...
IPC-6012 is a performance specification document. It defines the default requirements and specifications for each type of PCB (Class 1, Class 2 and Class 3). PCBs belonging to Category 1 are conventional electronic boards with the shortest service life and simpler functions, such as those used ...
