DESCRIPTION

Production is strictly controlled and follows an extensive set

of instructions established for reproducibility. A cermet film

layer and a glass-over are deposited on a high grade (Al2O3)

ceramic substrate with its prepared inner contacts on both

sides. A special laser is used to achieve the target value by

smoothly fine trimming 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 on 100 % of the individual chip

resistors. Only accepted products are laid directly into

the tape in accordance with IEC 60286-3 Type 1a and

Type 2a (1)

.

ASSEMBLY

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 (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.

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.
