HDI – high density interconnect PCBs – design trends
Electronic products are becoming more and more complex. The miniaturization of electronic components pushes the evolution of printed circuit boards towards complexity that was unthinkable only a few years ago. The need arises when one no longer thinks of an object that has a single and simple function, but of objects that are evolving in […]
Via hole protection – what is it and when can it be used
Via hole protection is a PCB manufacturing technique in which the via hole is filled with solder mask or epoxy.
PCB design tips: Via-in-pad
The benefits of via-in-pad designs are well documented. From reduction of inductance to increased density, via-in-pad has become an essential tool for designers when navigating the routing challenges of fine pitch array packages that have become mainstays in today’s BOMs but there are trade-offs that must be considered. The basic concept is elegant. The via-in-pad […]
