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.
