The IC chip feature sizes and contact pads have been constantly reduced. Thus, the continuing increase in component performance and lead density, along with the reduction in package sizes, have required that PСB technology find ways to increase the interconnection density of the substrate. The main attention is paid to a question that serves as a protection from nursing of the solder in the through holes. and low. The described constructions for increase density interconnections of PCB are designed for high quality soldering.
multilayer wiring board, quality soldering, design wiring board for BGA, filling hole.
