This Standard specifies the requirements for properties of paper based phenolic resin
copper-clad laminates of both economic and high electrical grades, in thicknesses of
0.8 mm up to 3.2 mm.
NOTE 1 This Standard gives the specification concerning the characteristics of the
copper-clad laminates, the requirements of which present the values the
products are expected to have. This Standard, therefore, is not intended
to be used to conduct a conformity assessment by itself.
NOTE 2 The International Standards corresponding to this Standard and the sym-
bol of degree of correspondence are as follows.
IEC 61249-2-1 : 2005 Materials for printed boards and other interconnect-
ing structures Part 2-1: Reinforced base materials, clad and unclad--
Phenolic cellulose paper reinforced laminated sheets; economic grade,
copper clad
IEC 61249-2-2 : 2005 Materials for printed boards and other interconnect-
ing structures Part 2-2: Reinforced base materials, clad and unclad--
Phenolic cellulose paper reinforced laminated sheets, high electrical grade,
copper-clad
(Overall evaluation: MOD)
The symbols which denote the degree of correspondence in the contents
in the corresponding International Standard and JIS are IDT (identical),
MOD (modified) and NEQ (not equivalent) according to ISO/IEC Guide
