TH45588A - The power plane and the porous earthing plane to achieve reduced PCB separations and better stability. - Google Patents

Abstract

DC60 (26/05/43) The power plane and grounding plane, which are used in printed circuit boards (PCB) and which consists of porous conductive materials, are revealed. The porous earthing planes in the PCB allow liquids (such as water and / or other solvents) through the power and grounding planes. This will reduce the interruption in the PCB (or PCB used as the stacking chip backing) caused by the growth of the fibers as the negative / positive electrodes and Separation into the insulating layer Conductive material Porous! Suitable for use in PCBs may be built. By using metal-coated organic materials (such as polyester or liquid crystal polymers) or material (eg, fabricated materials). From carbon / graphite or fiberglass) using metal wire mesh instead of thin sheet metal using Or by creating a porous thin sheet metal by creating sequences of holes in the thin sheet metal The material and the net may be woven or random if a sequence of holes is made in thin metal sheets. An array of this type may be created. Without processing steps In addition to operations using conventional PCB assembly methods, the power and grounding planes used in printed circuit boards (PCBs) and which contain porous conductive materials are revealed. Power and The porous earthing planes in the PCB allow liquids (such as water and / or other solvents) through the power and grounding planes.

Conductive material Porous! Suitable for use in PCBs may be built. By using metal-coated organic materials (such as polyester or liquid crystal polymers) or material (eg, fabricated materials). From carbon / graft or fiberglass) using metal wire mesh instead of thin sheet metal using Or by creating a porous thin sheet metal by creating sequences of holes in the thin sheet metal The material and the net may be woven or random if a sequence of holes is made in thin metal sheets. An array of this type may be created. Without processing steps It goes beyond the operations of conventional PCB assembly methods.
