Document Type and Number:
WIPO Patent Application WO/2010/082712
Kind Code:
A1
Abstract:
The present invention relates to a sensor device protected by a film layer and a resin layer. More particularly, the present invention relates to a sensor device protected by a film layer and a resin layer, comprising: a sensor element; lead frames between which the sensor element is inserted and fixed; a first head protection film deposited to protect a head portion which comprises the sensor element fixed between the lead frames; an insulating film which contains the first head protection film and which covers and is coated on the lead frames to insulate the lead frames; and a second head protection film deposited to further cover the head portion covered with the insulating film. An epoxy is applied onto the insulating film which is coated on the head portion serving as the sensor element to maintain the strength of the sensor device by the force of the epoxy, thereby significantly improving impact resistance and compression strength.
