DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a high
grade (Al2O3) ceramic substrate and conditioned to achieve
the desired temperature coefficient. Specially designed
inner contacts are deposited on both sides. A special laser
is used to achieve the target value by smoothly fine trimming
the resistive layer without damaging the ceramics. A further
conditioning is applied in order to stabilize the trimming
result. The resistor elements are covered by a blue
protective coating designed for electrical, mechanical and
climatic protection. The terminations receive a final pure tin
on nickel plating.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. This
includes full screening for the elimination of products with
potential risk of early field failures (feasible for R 10 ).
Only accepted products are laid directly into the paper tape
in accordance with IEC 60286-3 (3).
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems and for automatic soldering using wave,
reflow or vapour phase. The encapsulation is resistant to all
cleaning solvents commonly used in the electronics
industry, including alcohols, esters and aqueous solutions.
The suitability of conformal coatings, if applied, shall be
qualified by appropriate means to ensure the long-term
stability of the whole system.
The resistors are RoHS compliant, the pure tin plating
provides compatibility with lead (Pb)-free and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven under
extensive testing.
All products comply with the GADSL (1) and the
CEFIC-EECA-EICTA (2) list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
• 2000/53/EC End of Vehicle life Directive (ELV) an
Annex II (ELV II)
• 2011/65/EU Restriction of the use of Hazardous
Substances Directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
APPROVALS
The resistors are approved within the IECQ-CECC Quality
Assessment System for Electronic Components to the detail
specification EN 140401-801 which refers to EN 60115-1,
EN 140400 and the variety of environmental test procedures
of the IEC 60068 (3) series.
Conformity is attested by the use of the CECC logo ( ) as
the mark of conformity on the package label.
Vishay Beyschlag has achieved “Approval of
Manufacturer” in accordance with IECQ 03-1. The release
certificate for “Technology Approval Schedule” in
accordance with CECC 240001 based on IECQ 03-3 is
granted for the Vishay Beyschlag manufacturing process.
