ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000
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 ceramic (Al
2
O
3
) 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 cutting a meander
groove in the resistive layer without damaging the ceramics.
For the high ohmic range, optimized cermet products provide
comparable properties. The resistor elements are covered
by a 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 performed on 100 % of the
individual resistors. This includes pulse load screening for
the elimination of products with a potential risk of early life
failures according to EN 140401-801, 2.1.2.2 (feasible for
R 10 ). Only accepted products are laid directly into the
paper tape in accordance with EN 60286-3
(3)
, Type I.
Products within a packaging unit are from the same
production lot and carry the same date code.
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic soldering
using wave, reflow or vapour phase as shown in
IEC 61760-1
(3)
. Solderability is specified for 2 years after
production or requalification. The permitted storage time is
20 years.
The resistors are RoHS compliant; the pure tin plating
provides compatibility with lead (Pb)-free soldering
processes. The immunity of the plating against tin whisker
growth has been proven under extensive testing.
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.
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) and
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 IEC QC 001002-3,
clause 2. The release certificate for “Technology Approval
Schedule” in accordance with CECC 240001 based on
IEC QC 001002-3, clause 6 is granted for the
Vishay BEYSCHLAG manufacturing process.
The Vishay BEYSCHLAG production facility is registered
with the CAGE code D9539.
