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 substrate (Al2O3) 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 and low 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 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 Type 1a (1).
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor phase as shown in
IEC 61760-1. 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, potting compounds and
their processes, 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
