Scope

GB/T 33016-2016 is the English-translated version of 多层印制板用粘结片试验方法.

This standard collects the test methods for the bonding sheet used in multilayer printed boards. Clause 1 states that it specifies the test conditions and the methods for appearance, for size and for the performance of the B-type adhesive sheet and of its laminated cured product, and that it applies to multilayer printed boards.

Clause 4 fixes the standard atmospheric conditions at 15 degrees C to 35 degrees C, 45 % to 75 % relative humidity and 86 kPa to 106 kPa, and the arbitration atmospheric conditions at 23 degrees C plus or minus 1 degree C, 48 % to 52 % relative humidity and the same pressure range, the latter to be used when the parameter measured depends on those conditions and the two sides dispute the result.

Clause 5, sample sampling, takes the sample from the head or the tail of a roll after at least 0.5 m, or at random from a number of sheets.

The directory then runs clause 6 appearance inspection, clause 7 size check, covering length, width, thickness and two verticality methods, method A by rectangular scale and method B by diagonal, and clause 8 B grade adhesive sheet inspection, covering resin content, resin flow, gel time and volatile content.

Clause 9, lamination of cured materials, is the longest, with twelve subclauses: curing thickness, flammability, chemical resistance, electrical strength, dielectric constant and loss factor, insulation resistance, surface resistivity and volume resistivity, glass transition temperature, Z-axis thermal expansion coefficient, thermal decomposition temperature, thermal stratification time and halogen content.

A normative Appendix A gives the quality per unit area of fiberglass cloth and an informative Appendix B lists test methods for adhesive sheets for multilayer printed boards at home and abroad; the draft itself stops after clause 5, so none of the test procedures is shown.

Clause 2 cites GB/T 1409-2006, GB/T 2036 and GB/T 33015-2016, and clause 3 takes its terms and definitions from GB/T 2036 and GB/T 33015-2016.

It was proposed by the Ministry of Industry and Information Technology of the People's Republic of China, is administered by the National Printed Circuit Standardization Technical Committee (SAC/TC47), was issued on 2016-10-13 and has applied since 2017-11-01.

The terms and definitions defined in GB/T 2036 and GB/T 33015-2016 apply to this document.

4 Test conditions

4.1 Standard atmospheric conditions

Unless otherwise specified, the test shall be carried out under standard atmospheric conditions. The standard atmospheric conditions are.

a) Temperature. 15 ° C to 35 ° C;

b) relative humidity. 45% to 75%;

c) air pressure. 86kPa ~ 106kPa.

4.2 Arbitration of atmospheric conditions

If the parameters to be measured depend on temperature, relative humidity and air pressure, and the supply and demand sides of the test results are controversial, the test should be in the arbitration atmosphere Conditions. Arbitration Atmospheric conditions.

a) Temperature. 23 ° C ± 1 ° C;

b) relative humidity. 48% to 52%;

c) air pressure. 86kPa ~ 106kPa.

5 Sample sampling

Unless otherwise specified, for a roll-like adhesive sheet, at least 0.5 m after the volume head, the volume of the head or the tail is taken as a sample;

Tablets, in a certain number of adhesive tablets randomly selected as a sample.
