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 substrate (Al2O3) using a mask to separate
the adjacent resistors 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.
The resistor elements are covered by a protective coating
designed for electrical, mechanical and climatic protection.
The terminations receive a final pure matte 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. Only
accepted products are laid directly into the paper tape in
accordance with IEC 60286-3, Type 1a (1).
ASSEMBLY
The resistors are suitable for processing on automatic
SMD assembly systems. They are suitable for automatic
soldering using reflow or vapor phase as shown in
IEC 61760-1 (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
matte tin plating provides compatibility with lead (Pb)-free
and lead-containing soldering processes. The permitted
storage time is 20 years, whereas the solderability is
specified for 2 years after production or requalification. The
immunity of the plating against tin whisker growth has been
proven under extensive testing.
MATERIALS
