Sustainability Aspects: Obsolescence • For each applicable component in your block BOM, perform a variance analysis • 1st Consider the part type: Find the u+(2.5)s, u+(3.5)s dates • 2nd Consider any applicable attributes • 3rd For each attribute find the u+(2.5)s, u+(3.5)s dates • Find the worst case u+(2.5)s, u+(3.5)s dates • Use u, s in years • +2s to +3s from Peak = Phase Out Product • +3s and higher from Peak = Obsolete Product • Create a separate BOM table of obsolescence analysis with above data • ID all parts above the 2.5s, Separately ID all above 3.5s Formulate Corrective Actions or Risk Mitigations Note: If you have a component that does not fit any category, ignore it for this analysis

Waste Electrical and Electronic Equipment (WEEE)Restrictions on Hazardous Substances (RoHS) European Community Directives 2002/95/EC & 2002/96/EC Will impact global electronics industry (incl USA)
“This symbol indicates that the waste of electrical and electronic equipment must not be disposed as unsorted municipal waste and must be collected separately. Please contact t he manufacturer or other authorized disposal company to decommission your equipment.” WEEE Directive 2002/96/EC “on Waste Electrical and Electronic Equipment“ • Producers must take back waste electronic equipment from collection points • Financing: • Producers/Importers are responsible for financing and treatment of waste equipment from private households (which includes most small businesses) • Product sales can show a visible fee for up to 10 years • Producers and users others than private households may conclude agreements stipulating other financing methods • Products have to be marked with the brand of the producer, recycling symbol & date • Producers must provide specific disassembly information for treatment facilities • Targets are set in the directive for reuse, recovery and recycling (ex. Medical) • Producers/Importers have to be registered with local systems • Member states have to report on the targets; so record keeping required Labeling Must Include the WEEE Symbol and Guidance Info Date of manufacture: month / year Typical Guidance Statement for Industrial Equipment
WEEE Regulated Materials and Devices • 1) Polychlorinated biphenyls (PCB) containing capacitors in accordance with Council Directive 96/59/EC of 16 September 1996 on the disposal of polychlorinated biphenyls and polychlorinated terphenyls (PCB/PCT) (1). • 2) Mercury containing components, such as switches or backlighting lamps, • 3) Batteries Including, • Lithium batteries • Alkali-Manganese batteries • Dry cell batteries • Nickel-cadmium rechargeable batteries • Lead rechargeable batteries • Silver round cell batteries • 4) Printed circuit boards of mobile phones generally, and of other devices if the surface of the printed circuit board is greater than 10 square centimeters. • 5) Toner cartridges, liquid and pasty, as well as color toner. • 6) Plastic containingbrominated flame retardants. • 7) Asbestos waste and components which contain asbestos.
WEEE Regulated Materials and Devices • 8) Cathode ray tubes • 9) Refrigerant including chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons & hydrocarbons • 10) Gas discharge lamps such as halogen, neon, xenon, etc • 11) Liquid crystaldisplays (together with their casing where appropriate) of a surface greater than 100 square centimeters and all those back-lighted with gas discharge lamps • 12)External electric cables • 13)Components containingrefractory ceramic fibers as described in Commission Directive 97/69/EC of 5 December 1997 adapting to technical progress Council Directive 67/548/EEC relating to the classification, packaging and labeling of dangerous substances (2). • 14) Components containingradioactive substances (except components below exemption thresholds set in Art. 3 of and Annex I to Directive 96/29/Euratom of 13 May 1996 laying down basic safety standards for the protection of the health of workers and the general public against the dangers arising from ionizing radiation (3)) . • 15) Electrolytic capacitors containing substances of concern (height > 25 mm, diameter > 25 mm or proportionately similar volume) .
Member States can expand the equipment list Producers will be accountable for records of annual mass of each restricted substance shipped into each EC country But conflicts among accounting firms on how to reserve for WEEE obligations, some countries may charge up-front Firms may have to pay into a deposit system; and reserve for a contingent liability Some European wide associations being formed to manage WEEE But member states have strong incentive to keep all waste in their system to maximize fee income Definition of “producer” is problematic What happens if distributors ship equipment from one member state to another? Who is responsible as the “producer”? WEEE Implementation Difficulties
