RoHS Directive is driving electronics manufacturers to manage and exchange product content information across the supply chain. While material declarations are not considered sufficient on their own to ensure RoHS compliance, they provide a key building block for an overall compliance model. The most efficient approach to exchanging material composition data is to standardize stan·dard·ize

Development of the IPC-1750 series began with two iNEMI projects that brought together users and solution providers to shape standards-based processes for communicating materials content data. The specifications they developed were handed off to the IPC Declaration Process Management subcommittee for development and standardization standardization
In industry, the development and application of standards that make it possible to manufacture a large volume of interchangeable parts. Standardization may focus on engineering standards, such as properties of materials, fits and tolerances, and drafting . More than 50 of the largest OEMs, EMS providers and suppliers helped define the business requirements and develop specifications for these standards.
Enter IPC-1752. IPC-1752, "Materials Declaration Management," provides a common data model and standardized forms to simplify the way industry collects, tracks and discloses material content information. It supports small- and mid-sized companies, where the interaction is more likely to be manual, as well as multinationals, where IT budgets can support automation and direct B2B (Business to Business) Refers to one business communicating with or selling to another.

IPC-1752 was released in February, with a number of major OEMs, EMS providers and component manufacturers declaring their support and intentions for adoption. Draft versions of the standard have been wrung wrung

Currently the RoHS Directive does not require producers or suppliers to provide material composition declarations (MCDs). However, it is generally recognized that MCDs are needed to manage compliance risk, support supplier liability claims and perform product level compliance analysis. Further, there are references made to "technical documentation" and material declarations in the RoHS Guidance documents published by the U.K. Department of Trade and Industry The Department of Trade and Industry was a United Kingdom government department which was disbanded with the announcement of the creation of the Department for Business, Enterprise and Regulatory Reform on 28 June 2007. . These documents indicate that producers are expected to collect and maintain documentation that will support that they have conducted "due diligence Research; analysis; your homework. This term has caught on in all industries, because it sounds so "wired." Who would want to do analysis or research when they can do due diligence. See wired. " in ensuring that their suppliers are providing compliant parts.

IPC-1752, along with the International Electrotechnical Commission's Publicly Available Specification document 61906 (which provides high-level requirements for material declarations) and JIG 101 form the basis for a material declaration standard that has been proposed to the IEC (International Electrotechnical Commission, Geneva, Switzerland, www.iec.ch) An organization that sets international electrical and electronics standards founded in 1906.

While other formats for material declarations are being used or developed (examples include Japan's JGPSSI spreadsheet and the automotive industry's Compliance Connect spreadsheet), none has the international support and momentum that IPC-1752 is now receiving.
Flavors of IPC-1752
IPC-1752 meets key business requirements while providing the flexibility needed to support different elements of the supply chain. It provides several user configuration options, is platform independent (Windows, Linux, Solaris, Mac) and does not require suppliers to purchase specific software to complete declarations.
The standard includes a single data model and supporting XML schema, plus there are two forms, IPC-1752-1 and IPC-1752-2. The forms, based on Adobe .pdf forms, use a UML (Unified Modeling Language) An object-oriented analysis and design language from the Object Management Group (OMG). Many design methodologies for describing object-oriented systems were developed in the late 1980s. data model developed with the assistance of the National Institute of Standards and Technology National Institute of Standards and Technology, governmental agency within the U.S. Dept. of Commerce with the mission of "working with industry to develop and apply technology, measurements, and standards" in the national interest. . They can be printed or exchanged via electronic means from e-mail and Web interfaces. TABLE 1 shows how the two forms support the various reporting levels Reporting Level
A level of ownership of a specific futures position wherein the holders exceed the stated amounts and are required by the CFTC to submit daily reports.
Also known as reporting limit. .
The standard supports three levels of declaration:
1. Item-level RoHS declaration in yes/no format, with identification of any applicable exemptions (supported by both forms).
2. RoHS and JIG level A and B and other substances requested, declared at the item level (except for RoHS restrictions) with identification of any applicable exemptions, as well as providing substance ppm or weight if above thresholds. (Requestors would choose IPC-1752-1 form if they want this level.)
3. Declaration of RoHS, JIG A and B, and other substances at the homogeneous material level, up to full declaration and also including identification of any applicable exemptions. (Requestors would choose IPC-1752-2 form if they want this level.)
While there are technically six classes of reporting, there are really only the original three required levels of declaration, with the ability to include manufacturing process information, such as lead finish, maximum reflow (1) The process of heating and melting the solder that has been screen printed onto a printed circuit board in order to bond chips and other components to the board. Surface mount chips (SMT) use the reflow method. Contrast with wave soldering. See also reflowable text. temperature and moisture sensitivity level Moisture Sensitivity Level relates to the packaging and handling precautions for some semiconductors. The MSL is an electronic standard for the time period in which a moisture sensitive device can be exposed to ambient room conditions (approximately 30°C/60%RH). .
IPC-1752 integrates and leverages several industry efforts, establishing a common solution that is shaped not only by regulatory guidelines but also by industry needs and requirements. It can help eliminate the costly and burdensome use of multiple material declaration formats. At the same time, it provides flexibility, allowing users to select from several options in terms of the level and scope of the data requested. While no standard is perfect, rapid adoption of IPC-1752 represents the best available option for the industry to efficiently meet the business and information needs of the impending im·pend
