Modular testprocessor for VLSI chips and high-density PC boards
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1988A method for the test of VLSI chips and high-density PC boards is proposed. A built-in, microprogrammable test controller, called a testprocessor, applied tests to all separately testable blocks within either a VLSI chip or PC board, hence increasing controllability and observability.

High Density Metal Core Printed Circuit Boards
Circuit World, 1981To solve the problems associated with heat generation as packaging density increases, especially with the use of VSLI devices, high density metal core PCBs have been developed. The manufacturing process is evaluated alongside that of conventional G‐10 boards, as are the electrical properties of the two types.

Influence of density particle board on the quality of their surface
Известия СПбЛТА, 2016Повышение плотности древесностружечных плит в диапазоне от 500 до 750 кг/м3 приводит к замедлению процесса впитывания жидкостей поверхностью плит. Изменение скорости впитывания объясняется повышением плотности поверхностного слоя плит, однако она имеет величины ниже средней плотности плит.

High Density Flex‐rigid Circuits — A Solution for Board‐to‐board Transmission Line Interconnects
Circuit World, 1993Flex‐rigid circuits have been used for many years, primarily by the military, as a method to reduce the size and increase the reliability of electronic systems. However, in today's emerging designs where high speed ASICs are often the dominant components, flex‐rigid circuit assemblies are now an attractive solution for providing high density ...
