IPC released two draft standards addressing how industry collects, tracks and discloses product material content information. The standards are designed to help companies meet the European Union Restriction of Hazardous Substances (RoHS) Directive and other materials restrictions.
The two draft standards are:
- IPC-1751 - Generic Requirements for Declaration Process Management - describing all generic requirements, including company information.
- IPC-1752 - Materials Declaration Management - establishing electronic data formats and providing standardized forms to simplify the exchange of materials declaration information.
IPC-1752 outlines a supply chain materials declaration format and process for meeting environmental regulation compliance.
The standard provides a material content declaration (MCD) form, which is intended to simplify and improve material composition data exchange throughout the supply chain. The form is based on an underlying XML schema, which in turn is represented by a Unified Modeling Language (UML) data model. Data entered into the form, according to IPC, conforms to the schema requirements because the form design tool binds the schema elements directly to the form fields, thereby ensuring a higher level of data quality.
The data captured by these forms can then be extracted and exchanged in a standard XML format which will conform to related RosettaNet PIPs (Partner Interface Process).
The MCD forms facilitates three levels of declaration using two different forms:
- A general yes/no RoHS compliance declaration.
- A Class I JIG (Joint Industry Guide) declaration at the part level (IPC-1752-1 form).
- A Class II declaration which includes RoHS and JIG substances at the homogeneous material level, along with related manufacturing parameters (IPC-1752-2 form).
The forms can be exchanged via electronic means, from e-mail or web interfaces to advanced and secure business-to-business methods.
The draft standards and PDF forms were released last month for a 60-day industry review and can be accessed at http://www.ipc.org/IPC-175X.
Once feedback has been reconciled according to the American National Standards Institute (ANSI) standards approval process, the standards will be issued.
