WitrynaDefinition of a High-Density Interconnect (HDI) Printed Circuit Board. High-density interconnect, or HDI, circuit boards are printed circuit boards with a higher wiring density per unit area than traditional printed circuit boards. In general, HDI PCBs are defined as PCBs with one or all of the following: microvias; blind and buried vias; built ... IMS consists of a metal baseplate (aluminium is commonly used because of its low cost and density) covered by a thin layer of dielectric (usually an epoxy-based layer) and a layer of copper (35 μm to more than 200 μm thick). The FR-4-based dielectric is usually thin (about 100 μm) because it has poor thermal conductivity compared to the ceramics used in DBC substrates. Due to its structure, the IMS is a single-sided substrate, i.e. it can only accommodate componen…

WitrynaTo define the IMS Program Specification Blocks (PSB) for the IMS application you are deploying, use the following order for the Program Control Blocks (PCB): Gen requires I-O PCB first. By default, the I-O PCB is generated automatically from the initial request. Gen requires the second PCB to be an alternate, modifiable I-O PCB with … Witryna3 maj 2007 · PCB - This is Program communication block which is defined in Linkage of COBOL program.
