摘要:
The invention concerns a method for producing conductive via-connections in a substrate and substrates equipped with such connections. The method for producing conductive via-connections between the front face (2) and the rear face (3) of a substrate consists in: producing in the substrate (1) on the side of the rear face (3), cavities (5) with predetermined depth and cross-section for defining pads (4) with specific cross-section designed to ensure electrical conduction between the two faces (2, 3) and filling up the cavities (5) with a dielectric material (7). The substrate is equipped with conductive via-connections between its front face (2) and its rear face (3). The conductive connections are provided by the pads (4) defined by the cavities (5) filled with a dielectric material (7). The invention is particularly applicable to substrates used for making microsensors.

Methods for protecting an electronic device from contaminants by applying different polymeric materials to different vital components of a device are disclosed. In one embodiment, the method comprises applying (110,120) a first polymer, such as (210,220) an acrylic-based polymer, to one or more connectors and components located on the printed circuit board of the device. The method further comprises applying (140) a second polymer, such as a silicone-based polymer, to different connectors and components on the printed circuit board. The method leads to different components being coated with a different polymers, without the need for multilayer coatings on any component. Electronic devices that are protected by such polymeric, hydrophobic coatings are also disclosed. Non-limiting examples of such devices include smart phones, computers, and gaming devices.

Methods for applying protective coatings to electronic devices that have already been assembled, and are in a consumer-ready or aftermarket form, are disclosed. In such a method, an electronic device may be at least partially disassembled to expose at least a portion of an interior of the electronic device. A protective coating is applied to some or all of the exposed surfaces of the electronic devices, including one or more internal surfaces, features or components of the electronic device. Thereafter, the electronic device may be reassembled. During and after reassembly, the protective coating resides internally within the electronic device. Systems for applying protective coatings to interior components of previously assembled electronic devices are also disclosed.

An electronic system may include a printed circuit board (PCB), a component affixed to the PCB, and a conformal coating layer on the PCB and the component. The conformal coating layer may include parylene. Furthermore, the electronic system may include an underfill layer adjacent to the conformal coating layer, filling a gap between the PCB and the component. Other embodiments may be described and/or claimed.

The properties of the conformal coating are tailored by tuning the values of x, y, z, a and b.
摘要:
Methods, and devices produced by the methods, for electroplating a multitude of micro-scale electrodes that are electrically isolated from each other on a cable or other device is described. A localized area of connections on another end of the cable is shorted together by depositing a metal sheet or other conductive material over the localized area. The metal sheet is connected to a terminal of a power supply, and the electrode end of the cable is immersed in an electrolyte solution for electrodeposition by electroplating. After the electrodes are electroplated, the metal sheet is removed from the cable in order to re-isolate the electrodes.
