1.0 Scope 1.1 Purpose This method is suitable for determining the volume permittivity, (dielectric constant) and loss tangent (dissipation factor) of insulating materials at 1 MHz. It is not dependent on either direct or indirect measurement of specimen thickness and [...]
1.0 Scope This test method is to determine the dielectric constant and dissipation factor of raw printed wiring board material at 1 MHz. 2.0 Applicable Documents None 3.0 Test Specimens Each specimen shall be 50.8 ± 0.076 mm [2.0 ± [...]
1.0 Scope This method is to comparatively determine the effects of printed conductor materials, conductor cross sectional measurements, substrate materials, and processes on the temperature D.C. current characteristics of printed wiring boards on a standard test sample. The temperature rise [...]
1.0 Scope To determine if the plated through-holes are sufficiently plated to withstand a relatively high current potential. 2.0 Applicable Documents None 3.0 Test Specimen Any plated through-holes on a test coupon or finished printed wiring boards. 4.0 Apparatus Power [...]
1 Scope 1.1 Purpose These tests are used as process control tools; they can be used to inspect printedboards or printed board assemblies and determine if they conform to the moniꢀtoring level of the user’s performance specification. Bulk ionic cleanliness [...]
FOREWORD The purpose of this test methods manual is to contain, in one document, pertinent information on test methods that will be useful to manufacturers and users of printed boards, electronic assemblies, hybrid circuits, discrete wiring, and flflat cable. It [...]
Substrate Electrographic Method 1 Scope This test method provides a procedure for testing the porosity of gold electroplated from an alkaline (cyanide), acid, or neutral gold plating solution on a nickel substrate in contact with the gold deposit. 2 Applicable [...]
1 Scope The purpose of this test is to measure the capacitance effects arising from plastic substrates, adhesives, or coatings, which may be critical to the reliable functioning of a circuit. 2 Applicable Documents None 3 Test Specimen Specimen thickness [...]
1.0 Scope This method describes a technique for evaluating a material to resist tracking when subjected to a low current arc just above the surface of the material. It can be used on materials of various thickness by stacking materials. [...]
