A transmission line should have a uniform characteristic impedance. Any variation or discontinuities to the impedance causes signal reflection and distortion.
At some level of circuit complexity, turning to an HDI architecture with blind and buried vias will result in better yield and lower cost than would a through-hole design. In
Designing a flex printed circuit board requires a slightly different approach than rigid PCBs. While flex PCBs can provide major savings in manufacturing cost as well as reduced space consumption
Use these four tips to become a high density interconnect printed circuit board design master.
Choosing the right dielectric material for a PCB is important no matter what application you’re working on, but the stakes are higher with High Density Interconnect (HDI) technologies.
In technology, nothing is possible until it is practical. For the wearables market, nothing is practical until it is fashionable. MIT experimented with head-mounted monstrosities in the early 1990s; a
