A test specimen is laid flat inside the mold between airtight sealing elements that leave exposed two ends of the test specimen on the inward facing direction of the layer. An air inlet and an air outlet respectively are arranged on the mold and correspond to the two exposed ends of the test specimen. The inlet is connected to the flow detecting element, and the outlet is connected to the vacuuming apparatus. Air is forced to move in a vacuumed cavity along the inward facing direction of the layer. Testing of air permeability of pre-impregnated material in solidification technique is allowed via adjustments of pressure and temperature.

摘要： It is provided a self-capacitance touch screen detection method, device and system. The method includes: receiving a scanning waveform by a currently detected channel of a self-capacitance touch screen; inputting the voltage of the scanning waveform into an input terminal of a voltage following unit, and driving at least a preset channel that is adjacent to the currently detected channel of the self-capacitance touch screen via an output terminal of the voltage following unit; and calculating self-capacitance touch screen coordinate data for a touch in the currently detected channel. The method not only avoids the disturbance to the detection for a touch in the currently detected channel generated due to water vapor or a water droplet, but also obtains an increased relative change generated by the same touch, and thereby the detection sensibility of the self-capacitance touch screen is improved.

摘要： Various embodiments of the invention provide laminate composite preform foils for high-temperature Pb-free soldering applications. The laminate composite preform foil is composed of a high-melting, ductile metal or alloy core layer and a low-melting solder coating layer at either side of the core layer. During soldering, the core metal, liquid solder layer, and substrate metals react and consume the low-melting solder phase to form high-melting intermetallic compound phases (IMCs). The resultant solder joint is composed of a ductile core layer sandwiched by the IMCs layers at substrate sides. The joint has a much higher remelt temperature than the original melting temperature of the initial solder alloy coating, allowing subsequent mounting of packaged devices.
