Preface |
Halogen free board materials have been developed and
introduced to the industry as environment friendly materials. JPCA has
developed specifications of some halogen free materials for the benefit of the
industry. A test method to measure halogen content in board materials,
JPCA-ES01, in this series was issued in November 1999. This document was also
proposed to IEC as an international standard and accepted as a work item of
IEC/TC91. It will be published in very near future.
Three years have passed since the publication of this
document and various comments have been made to JPCA-ES01 from users of this
document. JPCA decided to revise this document with the assistance of Sumibe
Techno Research Corp. The test method described in this document is certainly
not the only method to measure halogen content in a material. We should like
to appreciate to receive comments from those who use this document using the
comment form attached at the end for further improvement of this document.

1. SCOPE
This Specification specifies the measuring
method of chlorine and bromine content in organic copper-clad laminates and
their base materials to identify halogen-free printed wiring board materials.
2. PURPOSE
3. ANALYSIS METHOD
3.1 Test specimens
3.2 Test devices
3.3 Reagents
3.4 Preparation of test specimens
3.5 Preparation of test solution
3.6 Measurement of halogen ions and quantitative analysis
3.7 Calculation of halogen content
Informative Annex: Definition of "Halogen-free"
A copper clad laminates is recognized as "halogen-free" when the concentration of Chlorine
or Bromine satisfies the following requirement.
Chlorine ion concentration: Less than 0.09 wt% (900 ppm)
Bromine ion concentration: Less than 0.09 wt% (900 ppm)
Total concentration of Chlorine and Bromine ions: Less than 0.15 wt% (1500 ppm)
