China RoHS Compliance Roadmap
for Ecliptek Crystals and Oscillators

China RoHS

The Ministry of Information Industry (MII) of the People’s Republic of China developed and issued legislation called the "Measures for the Administration of the Control of Pollution of Electronic Information Products" released on February 28, 2006. This legislation, commonly referred to as "China RoHS", is intended to enhance environmental protection by requiring the reduction or elimination of toxic and hazardous substance in electronic products.

China RoHS applies to all "Electronic Information Products" (EIPs) containing toxic and hazardous substances that are available for sale in the Chinese marketplace, regulating the use of certain hazardous substances such as lead, cadmium, hexavalent chromium, mercury, and PBB/PBDE polybrominated flame inhibitors.

The China RoHS legislation is implemented in phases. The first stage applies to all EIP "Put on the Market" on, or after March 1st, 2007. This stage permits the use of restricted substances and requires the use of pollution control symbols indicating the presence of restricted substances and the "Environmental Protection Use Period" (EPUP). This phase also requires the disclosure of the restricted substances contained in EIP above the published "Maximum Concentration Values" (MCV).

On October 9, 2009 the Chinese government published the first draft of the "Key Administrative Catalogue for the Control of Pollution of Electronic Information Products" (Catalogue). In this second phase, EIP listed in the Catalogue are subject to China RoHS substance restriction requirements. The draft was published for consultation which ended a month later. Adoption of this legislation is still pending release and there has been no announcement of when it will enter into force.

China RoHS 2 Overview

On July 16, 2010 the Chinese Ministry of Industry and Information Technology (MIIT) released an exposure draft of a document titled "Measure for Administration of Pollution Control of Electronic and Electrical Products". This document, referenced as "China RoHS 2", is a revision of the earlier "Measures for the Administration of the Control of Pollution of Electronic Information Products" published by the MII. A key revision is the amending of the coverage of products by modifying the definition from EIP to Electrical and Electronic Equipment (EEE). The draft was published for consultation which ended a month later.

On June 4, 2012 the MIIT released a revised version of the China RoHS 2 draft first published in 2010. The new China RoHS 2 draft, called the "exposure draft version", aims to do the following:

  • Adds no new substances or changes in the maximum concentration values of these substances
  • Similar to the EU RoHS, product scope moves from EIP to EEE
  • Clarifies the definition of EEE
  • Clarifies the definition of hazardous substances
  • Adds requirements for product impact on the environment and human health
  • MIIT and the Certification and Accreditation Administration of China would receive more authority to implement China RoHS issues
  • Provides the development of a product compliance assessment system by MIIT and the Certification and Accreditation Administration of China
  • The "Key Administrative Catalogue for the Control of Pollution of Electronic Information Products" is renamed as the "Target Administrative Catalogue for the Pollution Control of Electrical and Electronic Products"

The draft was published for consultation. Adoption of this legislation is still pending release and there has been no announcement of when it will enter into force.

Ecliptek Corporation China RoHS Program

Ecliptek has implemented a China Restriction of Hazardous Substances (RoHS) Compliance program in response to international concerns about the environmental impact of Lead (Pb) and other hazardous substances used in the manufacturing of electronic components and assemblies.

To assist customers in meeting their China RoHS obligations, part number specific China RoHS Declarations are instantly available for most Ecliptek part numbers, and may be accessed on our Item Detail pages.

Use one of our Part Search methods to find your part number and go to its Item Detail page, or find the crystal or oscillator product series you need and then construct your part number from its Series home page.

This document provides a hazardous substance content disclosure table. The table provides a binary yes or no disclosure that indicates if homogeneous materials within the component or assembly contain specific substances that exceed the published MCV.

Ecliptek Corporation shall continue to monitor the status of RoHS legislation in China and provide regular updates to our customers. Ecliptek has established a China RoHS Team that meets regularly to coordinate all company activities, review Chinese RoHS legislation, and establish company China RoHS policy. Please contact our Global Customer Support Team if you have any questions about our program.

Ecliptek Definitions

China RoHS Compliance Classification
An Ecliptek component or assembly is classified as RoHS compliant when it contains none of the restricted substances over the maximum concentration values (MCV) tolerated by weight in homogeneous materials as shown in the table below.
Material Maximum Concentration Value (MCV)
Lead (Pb) 0.1% by weight
Cadmium (Cd) 0.01% by weight
Mercury (Hg) 0.1% by weight
Hexavalent Chromium (Hex-Cr) 0.1% by weight
Polybrominated Biphenyls (PBB) 0.1% by weight
Polybrominated Diphenyl Ethers (PBDE) 0.1% by weight
Components
Ecliptek's definition of components applies to quartz crystal devices.
Assemblies
Ecliptek's definition of assemblies applies to oscillator devices (MEMS Oscillators, XO, VCXO, TCXO, and OCXOs).

Solder Composition

Ecliptek has qualified the following Pb-free solder composition recommended by the North American Electronics Manufacturing Initiative (NEMI) and IPC's Solder Product Value Council (SPVC): Sn95.5Ag3.9Cu0.6 and Sn96.5Ag3.0Cu0.5, respectively, for attachment of Ecliptek components and assemblies to the printed circuit board.

Process Compatibility

The Ecliptek specification sheet identifies the suggested solder reflow profile(s). All Ecliptek China RoHS Compliant products are backwards compatible to lower temperature Tin-Lead (SnPb) reflow profile(s).
