An Introduction to HDI (High Density Interconnector) PCBS by PCBgogoNov 10.2018, 08:45:44
What are HDI PCBS?HDI PCBs are one of the fastest growing technologies in the field of PCB manufacturing. Anyone affiliated or interested in this industry is sure to come across this term every now and then. And if your company isn’t using them, you better start now. So the question lies, what are exactly HDI PCBS?HDI PCBs (High Density Interconnector) are essentiallya type of circuit board which has a higher wiring density per unit area as opposed to conventional boards. HDI PCBs help to make room on your printed circuit board while increasing their efficiency, allow for high frequency transmission, decrease redundant radiation etc.Characteristics of HDI PCBs: HDI PCBs have finer spaces and lines; have minor bias and increases connection pad density. The board has an overall increase in density because of the miniaturization and arrays of the electric parts. An HDI PCB usually consists of blind and buried vias and often microvias that are 0.006 or less in diameter.The placement of the...
An Introduction to Multilayer PCBsOct 09.2018, 17:13:50
PCBs are the basis of all electronic devices, without which that device cannot function. Essentially PCBs, also known as Printed Circuit Boards, consist of electric components and conductive traces that are built onto a board to help connect the components and to direct electricity. PCBs can be divided into distinctive types; one of them is Multilayer PCBs.What are Multilayer PCBs?Multilayer PCBs, as the name suggest are a combination of different layers. Single sided PCBs and double sided PCBs are both combined to give this complex designed PCB. Multilayer PCBs have increased number of layers and therefore have increased area available for wiring. The boards are made by combining double layered PCBs and separating them with insulating material such as dielectric.The Number of LayersThe minimum number of conductive layers between the insulating materials is three, and we can incorporate as much as a hundred layers according to our need. We consider Multilayer PCBs as Rigid PCBs because...
