3、 British Standard is the English language version of EN62326-4-1:1997. It is identical with IEC2326-4-1:1996. This Section of BS EN62326 forms the capability detail specification in the IEC quality assessment system for electronic components (IECQ) for rigid multilayer printed boards with interlayer
4、 connections with performance levels A, B and C. In the IECQ system, this specification is numbered QC230401.

Table 3 Tooling and processes The codification of the process capability shall be developed from Table 3. The process code is a series of significant letters (W, X, Y
47、and Z, each corresponding to a group of processes), each followed by one, three or four figures representing the columns within the group of processes. According to Table 3 the figures are 1, 2 or 4. If the manufacturer uses none, two or three of the referred facilities within a column, the followin
