【国外标准】 Standard Test Methods for Copper-Clad Thermosetting Laminates for Printed Wiring Boards (Withdrawn 2020)

AbstractThese test methods establish the standard procedures for testing copper-clad laminates produced from fiber-reinforced thermosetting polymeric materials intended for fabrication of printed wiring boards. The properties that these test methods shall examine are as follows: dielectric breakdown voltage parallel to laminations; dimensional instability; dissipation factor; flammability rating; flatwise flexural strength at room and elevated temperatures; behavior during oven blister test; peel strength at room and elevated temperatures; permittivity; pin holes and scratches in copper surface; purity of copper; behavior upong solder float test; solvent resistance; surface and volume resistivity; thickness; warp or twist; and water absorption.1.1 These test methods cover the procedures for testing copper-clad laminates produced from fiber-reinforced, thermosetting polymeric materials intended for fabrication of printed wiring boards.1.2 The procedures appear in the following sections:Procedure Section Referenced Documents 2 Conditioning 4 Dielectric Breakdown Voltage Parallel to Laminations 13 Dimensional Instability 19 Dissipation Factor 14 Flammability Rating Test 16 Flexural Strength, Flatwise at Elevated Temperature 15 Flexural Strength, Flatwise at Room Temperature 15 Oven Blister Test 17 Peel Strength Test at Elevated Temperature 10 Peel Strength Test at Room Temperature 9 Permittivity 14 Pin Holes in Copper Surface 20 Purity of Copper 5 Scratches in Copper Surface 21 Solder Float Test 8 Solvent Resistance 7 Surface Resistivity 11 Volume Resistivity 11 Terminology 3 Thickness & Thickness Variation 18 Warp or Twist 6 Water Absorption 121.3 Metric units are the preferred units for these test methods. Inch-pound units, where shown, are presented for information only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
