摘要:
An encapsulation composition for pressure signal transmission including a flexible and low modulus epoxy resin as a substance in combination with plastic balls with pressure signal transmission properties as filler is provided. Therefore, the pressure signal is transmitted by utilizing the property of easy deformation of the flexible epoxy resin under pressure. And the effect of signal transmission is enhanced by the contact between plastic balls. The encapsulation composition is used in a sensor for transmitting pressure signals. The encapsulation composition is hydrophobic, so an electronic device of the sensor can be protected against moisture or water to extend its lifetime. Compared with traditional sensors using liquid for transmitting pressure signal, this sensor using solid encapsulation composition has advantages such as easy production and processing.

A composite conductive film formed of a polymer-matrix and a plurality of conductive lines less than micro-sized and its fabricating method are provided. The conductive lines are arranged parallel and spaced apart from each other so as to provide anisotropic conductivity. The present conductive film can serve as an electrical connection between a fine-pitch chip and a substrate. Additionally, an adhesive layer is formed on two opposite sides of the conductive film along its conductive direction to increase adhesive areas. The strength and reliability of the package using the conductive film are thus enhanced.

A composite mode transducer for dissipating heat generated by a heat generating element is disclosed. The composite mode transducer includes a transducing module and connection elements. The transducing module includes first and second transducing elements connected in parallel. The connection elements are connected to resonance nodes of the first and second transducing elements. The first and second transducing elements are driven by a multiple-frequency resonance circuit, to produce resonance vibration of composite modes at resonance vibration frequencies of the system. The resulting advantages by using the composite mode transducer are: elimination of local stress concentration, and enhancement of efficiency, endurance and stability of the system. Accordingly, drawbacks of the prior art are overcome. The present invention further provides a cooling device with the composite mode transducer.
