    摘要: A flexible circuit board includes a substrate including a base layer and a bonding layer formed on each of opposite sides of the base layer. Each of the two bonding layers is formed by coating a bonding solution and drying the bonding solution. The bonding solution is composed of an adhesive and a solvent. A viscosity of the adhesive is 5000 millipascal-seconds. The adhesive is composed of a precursor having a mass fraction of 35%-65%, carboxyl modified polyphenylene oxide having a mass fraction of 10%-15%, bisphenol-F-epoxy resin having a mass fraction of 10%-15%, a silane coupling agent having a mass fraction of 0%-1.5%, silica filler having a mass fraction of 5%-20%, and a flame retardant filler having a mass fraction of 10%-20%.

    摘要: A cooling plate of a first embodiment of the present disclosure is configured with a electronic device for heat dissipation. The cooling plate of the first embodiment disclosure includes a first plate, a second plate opposite to the first plate, a bonding line connected with the first plate and the second plate, a plurality of supporting columns, and a cooling liquid received between the first plate and the second plate. The first plate, the second plate, and the bonding line together define a cavity, the plurality of supporting columns and the cooling liquid are received in the cavity. The plurality of supporting columns connects perpendicularly with the first plate and the second plate. The cooling liquid communicates between the plurality of the supporting columns.

    摘要: A heat dissipation device includes etched or other grooves for adhesive surrounding etched or other recesses for heat-dissipating fluid, these being created in a first copper sheet and a second copper sheet brought together. The first copper sheet includes first recesses and the second copper sheet includes corresponding second recesses. The second copper sheet is adhesively fixed on the first copper sheet and an airtight receiving cavity is formed by the first and second recesses being brought together. The heat-dissipating fluid in the airtight receiving cavity carries away heat generated by a heat-producing device to which the heat-dissipating device is fixed.
