正当众多公司努力采取各项措施以符合欧盟有害物质管制条例的时候，供应链的上下游公司被来自不同方面的需求所淹没，他们被要求提供各自产品精确和详尽的信息。一年多来，IPC，iNEMI（国际电子制造业协会）和RosettaNet已经采取措施，努力使业界在信息的采集、追踪和产品材料内容方面进行精简并标准化。业界领先的OEMs和EMS，以及解决方案提供商，合作完成了iNEMI的两个项目，为业界标准的数据交换结构定义了采集流程和格式。
As many companies struggle to determine their strategy for meeting the European Union (EU) Restriction of Hazardous Substances (RoHS) Directive and other materials restrictions, companies throughout the supply chain are being inundated with a multitude of differing, detailed requests for information about the precise materials content of their products.
For more than a year now, global efforts by IPC, iNEMI and RosettaNet have been underway to simplify and standardize how the industry collects, tracks and discloses product material content information. The industry's leading OEMs, EMS providers and solution providers, working through two iNEMI projects, defined a data collection process flow and data format for industry-standard material composition data exchange.
From these efforts has come a family of supplier declaration standards, namely two in draft form, IPC-1751, Generic Requirements for Declaration Process Management - describing all generic requirements, including company information and, IPC-1752, Materials Declaration Management - establishing electronic data formats and providing standardized forms to simplify the exchange of materials declaration information.
IPC-1752 IPC-1752 outlines a supply chain materials declaration format and process that provides a simple, effective approach to assist companies in meeting environmental regulation compliance. The standard provides a material content declaration (MCD) form, which will simplify and improve material composition data exchange throughout the supply chain, driving cost savings and efficiencies. The forms are based on an underlying XML schema, which in turn is represented by a UML data model. Data entered into the form is forced to conform 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 the 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), and 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.
