Flexible Printed Circuit Board as Novel Electrodes for Acoustofluidic Devices
نویسندگان
چکیده
Surface acoustic wave (SAW)-based acoustofluidics shows broad applications in biomedicine and chemistry. Conventional manufacturing process for SAW devices uses photolithography metal deposition, thus requires accessing cleanroom facilities. This study presents an efficient versatile technique based on a flexible printed circuit board (FPCB) developing acoustofluidic devices. By mechanically clamping interdigital electrodes (IDEs) made the FPCB onto piezoelectric substrate, SAWs can be effectively generated with additional matching network. The amplitudes were measured by laser vibrometer, which increases applied input voltage. FPCB-SAW device has been to actuate 10-?m microspheres form strong streaming vortices inside droplet, drive sessile droplet transportation substrate surface. use of rather than rigid (PCB) help cut down overall footprint save space. low requirement assembling facilitate providing fast prototyping

متن کاملPrinted circuit board inspection
This paper provides a general overview of immediate and long-term aims of the printed circuit board inspection project of The Robotics Institute. Its purpose is to highlight some of the significant issues specific to printed circuit board inspection and to provide a discussion of our basic thesis that machine inspection should be coupled with machine diagnosis of the causes of observed printed ...
متن کاملOptimization of electronic devices placement on printed circuit board
Power densities generated in today’s electronic components arise very quickly. Optimal placement of the devices on the board plays very important role for dissipation of power to the ambience. Each electronic component, as a heat source, thermally interacts with other ones. Forced convection is still one of the most important ways of heat dissipating from electronic components. When fluid moves...
متن کاملPrinted Circuit Board Deconstruction Techniques
The primary purpose of printed circuit board (PCB) reverse engineering is to determine electronic system or subsystem functionality by analyzing how components are interconnected. We performed a series of experiments using both inexpensive home-based solutions and state-of-the-art technologies with a goal of removing exterior coatings and accessing individual PCB layers. This paper presents our...
متن کاملNovel waste printed circuit board recycling process with molten salt
The objective of the method was to prove the concept of a novel waste PCBs recycling process which uses inert, stable molten salts as the direct heat transfer fluid and, simultaneously, uses this molten salt to separate the metal products in either liquid (solder, zinc, tin, lead, etc.) or solid (copper, gold, steel, palladium, etc.) form at the operating temperatures of 450-470 °C. The PCB rec...
