Fortiming RoHS (Pb-Free) Compliance Roadmap

RoHS (Pb-Free) Overview

In December 2002, the European Union Parliament approved the content of two directives to better control the management of waste electronic equipment.  The two directives are the Waste from Electrical and Electronic Equipment (WEEE) and the Restriction of Hazardous substances (RoHS).  The WEEE addresses the collection and treatment requirements of waste electronic equipment for the member countries.  The RoHS sets phase-out dates for the use of lead (Pb) and several other materials (Cd, Hg, Cr VI, etc) contained in electronic products.  The RoHS states that the following six (6) hazardous substances are restricted for use in electrical and electronic equipment unless there is an exemption provided in the rule: Mercury (Hg), Lead (Pb), Hexavalant Chrome (CrVI), Cadmium (Ca), Poly-brominated bi-Phenol (PBB), and Poly-brominated di-Phenol Ether (PBDE).

Fortiming RoHS (Pb-free) Program

The Fortiming Pb-free program is implemented in accordance with European Union (EU) Legislation titled "Restriction of the use of certain Hazardous Substances (RoHS)" including banning the use of Pb and other five hazardous substances in electronic assemblies after July 1, 2006.  It can also be classified as RoHS 6/6 Compliance.

Definitions

RoHS Compliance Classification: Component and Assembly shall be compliant to Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the restriction of the use of certain hazardous substances in electrical and electronic equipment.

Pb-Free Classification: Component and Assembly Pb content shall be less than 0.1% by weight of the device (in accordance to IPC/EIA J-STD-006) and shall not be intentionally introduced.

Components: Fortiming's definition of components apply to quartz crystal devices.

Assemblies: Fortiming's definition of assemblies apply to oscillator devices and modules (XO, TCXO, OCXO. VCXO and multi-pole MCF's)

Recommended Solder Composition

Fortiming has qualified the following Pb-free solder composition recommended by the North American Electronics Manufacturing Initiative: Sn95.5Ag3.9Cu0.6

RoHS Compliant Part Number Identification:

When applicable, the Fortiming specification sheet shall indicate if the device is classified as RoHS compliant (Pb-free).

RoHS 5/6 Compliance  RoHS56.jpg

RoHS 5/6 compliance indicates that 5 out of the 6 hazardous substances are not present in the device.  However, these devices do contain Lead Pb, as permitted by the following exemptions specified in the Annex of the RoHS directive.

1. Lead in glass of cathode ray tubes, electronic components and fluorescent tubes.
2. Lead in solders for servers, storage and storage array systems.
3. Lead in solders for network infrastructure equipment for switching, signaling, transmission as well as network management for telecommunication.

These parts can be identified by the blue RoHS 5/6 diamond above.

Process Compatibility

All Fortiming RoHS compliant products are backwards compatible to earlier lower temperature solder reflow profiles.

Marking and Labeling

Fortiming has a Pb-free labeling method for the packaging of all Pb-free products.  The lowest level shipping container will identify the products as Pb-free, if the customers desire.

Fortiming's Two Phase Implementation Plan

Fortiming is implementing their RoHS (Pb-free) Program in two phases. The details of the two phases are listed below.
