Porous power and ground planes for reduced PCB delamination and better reliability

Power and ground planes used in Printed Circuit Boards (PCBs) having porous, conductive materials allow liquids (e.g., water and / or other solvents) to pass through the power and ground planes, thus decreasing failures in PCBs (or PCBs used as laminate chip carriers) caused by cathodic / anodic filament growth and delamination of insulators. Porous conductive materials suitable for use in PCBs may be formed by using metal-coated organic cloths (such as polyester or liquid crystal polymers) or fabrics (such as those made from carbon / graphite or glass fibers), using metal wire mesh instead of metal sheets, using sintered metal, or making metal sheets porous by forming an array of holes in the metal sheets. Fabrics and mesh may be woven or random. If an array of holes is formed in a metal sheet, such an array may be formed with no additional processing steps than are performed using conventional PCB assembly methods.

Quick high-flexibility manufacturing method for ceramic circuit board

A quick high-flexibility manufacturing method for a ceramic circuit board comprises the following steps: irradiating laser on the surface of a ceramic matrix, and controlling the energy density of the laser to reach above the fracture threshold of the chemical bond of the compound containing active ions, so that chemical reaction occurs on the surface of the ceramic matrix, an active substance is separated out to serve as a chemical plating catalytic source, and the active substrate generated by the reaction and the matrix form chemical metallurgical bonding, wherein different laser sources are selected aiming at different ceramic materials according to the chemical bond energy of the ceramic material components, and the laser energy is controlled to reach the ceramic modified threshold by controlling the average power of laser output, pulse repetition frequency, scanning speed, defocusing amount, space between scanning line and scanning times; and the ceramic matrix modified by the laser is placed into a chemical plating solution to perform plating to form a metal coating. The surface of the ceramic is modified by the laser, so that a metal conductive layer and the matrix form chemical metallurgical bonding, the bonding force of the circuit board is greatly increased, and the heat-conducting property and the electric property are improved.

Rear contact solar cell and method for making same

The invention concerns a solar cell (1) and a method for making same, said solar cell (1) comprising on its rear surface (3) both the emission contact (43) and the base contact (45), those two contacts (43, 45) being electrically isolated from each other by flanks (5) whereof the metal coating has been removed. The emitting zones (4) of the rear surface (3) of the cell are connected by channels to the transmitter (9) of the front face (8) of the cell. The emitting zones (4) of the rear surface (3) of the cell and the channels (7) consist of a laser. The metal coating of the side walls is removed by selective etching, said metal coating being removed only in the zone of the flanks (5) where the etching barrier layer (11) is insufficient.
