BS PD IEC/TR 63017:2015

BS PD IEC/TR 63017:2015 specifies a compensation method of Cu linewidth according toimpeadance reduction by using noise suppression materials (hereafter referred to as NSMs)for FPCBs.This Technical Report presents an optimum result for maintaining a designated performanceof FPCBs by using NSMs. It also indicates a measuring method for an impedance variation ofFPCBs using NSMs with the prevailing TDR (time domain reflectometry) method. This methodis resticted to measuring only the variation of an impedance value in accordance with thevariation of the Cu linewidth by using NSMs for FPCBs. This report, however, neitherdetermines nor indicates the structure or material of FPCBs.Cross References:IPC 2141AIEC 62333-1:2006
