Meiwa provides low resistance metallic film elements with high thermal
resistance or fusing resistor elements with high fusing function, backed
up by superior plating technology. Both electrical and non-electrical plating
are available.
In case of the same resistance value, the film thickness of our products
has a tendency to be some more thin than that of our competitors. However
there are no problems about film strength. Besides the chemistry is right
between our film and a cutter knife. Therefore we can get a result of causing
less damage against our film and the cutter knife. |
