The via squeeze
Article Abstract:
Space constraints are causing designers to use microvias, which are holes so tiny they cannot be mechanically drilled, to connect the circuitry of one board layer to another. Vias now typically need to be less than 0.1 mm in diameter, and space for them is continuing to shrink. Instead of being drilled, they have to be made by alternative processes, such as laser ablation, or by photochemically etching thin dielectrics built up on the sides of a circuit board core. Microvias are becoming a crucial technology for meeting the electronics industry's needs in the areas of interconnections and packaging, and at the same time, microvia technology's transformations are forcing product and business changes throughout the printed-circuit supply chain.
