Tight spacing (less than 8 mils) between drilled holes and copper traces increases fabrication complexity and yield risk.

In the world of PCB manufacturing, knowledge of manufacturing constraints can help you design PCB using techniques that can guarantee reliable, economical and high-yield manufacturing. A wrong approach at the PCB layout stage can impact the complexity and cost of its fab and assembly. Understanding this enables you to develop smart practical design solutions for economical manufacturing and rapid prototyping cycles.

Ultra HDI changes the design for manufacturability equation.

As more teams begin to explore ultra HDI, one of the early surprises is just how different the design for manufacturability (DfM) conversation becomes. HDI gave us a playbook to follow, and many designers could recite those spacing and registration rules from memory. UHDI shifts that comfort zone. This technology opens remarkable routing opportunities, but it also requires us to revisit assumptions we have relied on for years.
