Five knowledge points of PCB Design technology–Hitech Circuits Co., Limited

1: Print line width selection: The minimum width of the printed line is related to the current flowing through the line: the line width is too small, the resistance of the printed line is large, and the voltage drop on the line is large, which affects the performance of the circuit. The width, the wiring density is not high, and the board area is increased. In addition to increasing the cost, it is not conducive to miniaturization. If the current load is calculated as 20A / mm 2 , when the thickness of the copper foil is 0.5MM (generally), the [...]

DESIGNING FLEXIBLE PRINTED CIRCUIT BOARDS( Part One)

A Flexible PCB is defined as an arranged pattern of integrated circuits and components that uses flexible based materials. Here, the same components used to produce rigid printed circuits boards might be used to fabricate these flexible electronic assemblies, but they should allow the flexibility of the board during its application. Some of the advantages provided by flexible PCBs include; low mass, greater reliability, high ductility, and space savings. But also, inventors/designers must be ready for their complexity and complications. Except for the fact that the designer must be accountable for the mechanical complexity related to a flex circuit, there’s [...]

DESIGNING FLEXIBLE PRINTED CIRCUIT BOARDS (Part Two)

High-density-Interconnect (HDI) Flexible PCBs When there are no adequate options provided by typical flexible circuits, HDI PCBs come into play by incorporating fine features like micro-vias, better layout, construction, and design. In addition to the above features, other features include; highly dense flex circuitry, Increased functionality, and smaller form factor. HDI technology offers improved electrical performance, access to advanced IC package use, and better reliability though it makes use of thinner materials.   Benefits of Flex Circuits As for a ribbon cable or discrete wiring replacement, customized repeatable routing supplied by flex circuits trails all through the assembly. Because of [...]
