The production process is tightly controlled and follows an extensive set of instructions to ensure repeatability. A uniform thin film of metal alloy is deposited on a high-grade ceramic substrate (Al₂O₃) and processed to achieve the desired temperature coefficient. Specially designed internal contacts are deposited on both sides. A special laser is used to smoothly trim the resistive layer to the target value without damaging the ceramic. Further processing is performed to stabilize the trimming results. The resistive element is covered with a protective coating providing electrical, mechanical, and climatic protection. Terminals receive a final pure matte nickel underplating with tin topcoat. Following the defined production process, results are verified through extensive test procedures and 100% optical inspection of individual chip resistors. This includes comprehensive screening to eliminate products with the potential risk of early field failures. Only accepted products are placed directly into paper tape in accordance with IEC 60286-3 Type 1a (1). These resistors are suitable for processing in automatic SMD assembly systems, as well as automatic soldering using wave soldering, reflow soldering, or vapor phase soldering. The packaging materials are resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters, and aqueous solutions. If conformal coatings, potting compounds, and their processes are used, they should be qualified by appropriate methods to ensure long-term stability of the overall system. These resistors are RoHS-compliant, and the pure matte tin coating is compatible with both lead-free (Pb) and leaded soldering processes. Solderability is guaranteed within 2 years of production or requalification. The permitted storage period is 20 years. Extensive testing has demonstrated that the plating is resistant to tin whisker growth. Vishay acknowledges the following hazardous substance regulatory frameworks: - IEC 62474, Material Declaration for Products of and for the Electrotechnical Industry, and the Declarable Substance List (DSL) contained therein (2) - Global Automotive Declarable Substance List (GADSL) (3) - REACH Regulation (1907/2006/EC) and its related Substances of Very High Concern (SVHC) list within the supply chain (4) The product contains none of the substances prohibited under the IEC 62474, GADSL, or SVHC lists; for details, see www.vishay.com/how/leadfree. The product therefore fully complies with the following directives: - 2000/53/EC End-of-Life Vehicles Directive (ELV) and Annex II (ELV II) - 2011/65/EU Restriction of Hazardous Substances Directive (RoHS) and amendment 2015/863/EU - 2012/19/EU Waste Electrical and Electronic Equipment Directive (WEEE) Vishay is committed to eliminating conflict minerals from its supply chain; for details, see the Conflict Minerals Policy at www.vishay.com/doc?49037. Where applicable, resistors are approved within the IECQ-CECC Electronic Component Quality Assessment System in accordance with detail specification EN 140401-801, which references EN 60115-1, EN 60115-8, and various environmental test procedures from the IEC 60068 (1) series. Compliance is demonstrated by use of the CECC mark as a conformity mark on the packaging label.
