What is HDI PCB? High-Density Interconnect (HDl) is simply a PCB with more number of interconnections, occupying minimalspace.This results in the miniaturization of the circuit board.The components are placed closer and the boardspace is significantly reduced but the functionality isn't compromised. To be more precise, a PCB with an average of 120 to 160 pins per square inch is considered as an HDI PCB. The HDl design incorporates dense component placement and versatile routing. The HDl popularized microviatechnology. A denser circuitry is crafted with the implementation of microvias, buried vias, and blind vias. Thedrill to copper is reduced in an HDl design. What are the advantages of HDI PCBs? ·Phenomenal versatility: HDl boards are ideal where weight, space, reliability, and performance are primary concerns. ·Compact design:The combination of blind vias, buried vias, and microvias brings down the board space requirement. ·Better signal integrity: HDl incorporates via-in-pad and blind via technology.This helps in placing thecomponents closer to each other which cuts down the signal path length.The HDl technology removes via stubs and therefore reduces reflections of signal and thus improving signal quality. Ittherefore remarkably improves signal integrity due to shorter signal paths. ·High reliability: The implementation of stacked vias make these boards a super shield against extremeenvironmental conditions. ·Cost-effective:The functionality of a standard 8-layer through-hole board (standard PCB) can be reduced to a 6-layer HDl board without compromising the quality. HDl inherently provides a better signal integrity performance than non-HDl because all the stray capacitancesand inductances get reduced when using small blind and buried vias. Since there are no stubs,the impedanceof microvias is close to the trace impedance.The stray capacitance of a normal via is much higher, which causesa greater discontinuity in impedance than a microvia does. Some of the significant differences between the HDI and conventional PCBs are listed below: HDI PCB Standard (Through-hole) PCB Higher component density per square inch Lesser compared to HDl Smaller, lighter boards with more functionality Larger and heavier boards lmplementation of Blind, buried, and microvias Laser direct drilling Through-holes Mechanical drilling Lower number of layers Higher number of layers Compatible with high pin count and low pitch packages May face compatibility issues with low pitch packages What are the applications of HDI PCBs? ·Healthcare industry--HDI PCB Technology has shown tremendous possibilities in the healthcare and medical fields. For example, tiny, implanted devices such as pacemakers, portable X-Rays and external devices such as hearing aids use the HDI PCB technology. ·Consumer devices--Due to the compact nature, the HDI PCBs are used in most consumer products such as smartphones, tablets, laptop computers, touch screen products and home appliances. ·Aerospace--High Density Interconnect PCB can withstand extreme environmental conditions making it feasible to be utilized in electronics design for missile systems, aircraft, and defense applications. ·Wearables--Due to the size of HDI PCBs, they are widely used in wearable technologies. For example, VR headsets, smartwatches, smart clothing, and more. Future of HDI PCB Technology Using High Density Interconnect PCBs will elevate your technology to a whole new standard. These small PCBs are cost effective, withstand higher frequencies, and are great when used in mobile devices, such as laptops, cell phones, and tablets. Need more advanced information?
