Resistors can be combined with wrap around
metalization with proper planning.
Thin
film resistors are usually made from a sputtered layer of tantalum
nitride (TaN), or nichrome (NiCr) with a specific resistance of
10 – 100 O/?. A typical resistor tolerance is ± 10% with tighter
tolerances available if necessary. Laser trimming can result in
tolerances of less than ±1%. If you are designing thin film resistors
into you circuit, the engineers at Precision Surface Technology
would like to discuss your requirements and suggest aspects of
your layout that will reduce manufacturing difficulties and give
a more reliable product.
