DESCRIPTION

Production is strictly controlled and follows an extensive

set of instructions established for reproducibility. A

homogeneous film of special metal alloy is deposited on a

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 unique 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. This

includes full screening for the elimination of products with

).

Only accepted products are laid directly into the paper tape

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

. 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.
