Hello, Welcome to the Altium Learning Hub

The very nature of microvias’ small size makes the acceptability criteria difficult to define. Most HDI Quality and Acceptability requirements are still OEM defined. The IPC has IPC-6016 as part of the IPC-6012, the generic QUALIFICATION AND PERFORMANCE SPECIFICATIONS (6010 SERIES). These specifications only cover the build-up HDI layers and not the core, which is covered by their own IPC specifications. IPC-6016 Qualification and Performance...

Why do we need to protect vias? Here to answer is Gerry Partida, Director of Engineering at Summit Interconnect Technologies. Summit is an advanced technology manufacturer creating custom printed circuit boards. Summit focuses on complex rigid and rigid-flex products and offers extensive expertise in RF/Microwave applications. In today’s episode, Gerry will help us untangle IPC 4761 and get actionable info that you can apply to your designs. L...

Even though building analog systems might seem like going back in time to the days of vacuum tubes, analog components and circuits are not going away any time soon, nor are the PCBs needed to support them. Purely analog circuit boards and mixed signal PCBs will remain important in many products and will continue to operate at a range of frequencies. Getting started with PCB design rules for analog circuits can be difficult in terms of where to...
