Choosing Smaller Footprints for HDI Design

Choosing Smaller Footprints for HDI Design

The main agenda of using HDI technology is to pack more components on a smaller board. Choosing smaller footprints for HDI increases board functionality and component density. Therefore, while designing a high-density interconnect board there are many problems to...

Key Aspects of DFM for HDI PCBs

Key Aspects of DFM for HDI PCBs

Design for manufacturability (DFM) for HDI PCBs refers to designing layouts that reduce the errors associated with fabrication and assembly. Before fabrication, the manufacturer will run a set of checks on the board files (Gerbers or ODB++) to confirm that these files...

Impedance Matching in HDI PCB Design

Impedance Matching in HDI PCB Design

Impedance matching is the way of configuring the input impedance of a load or the output impedance of its signal source. It is performed to achieve maximum power transfer and reduce the signal reflections from the load. In other words, for proper impedance control,...

How to Avoid Crosstalk in HDI Substrate?

How to Avoid Crosstalk in HDI Substrate?

Miniaturization of the copper features in electronic circuits results from placing interconnections closely with a high packing density. As a result, crosstalk in HDI PCB substrate comes at play because of the increased coupling between the adjacent signal lines. HDI...

How to breakout a .4mm BGA

How to breakout a .4mm BGA

One thing PCB designers will all agree on is that to breakout a BGA, you need precision and discipline. When you breakout a BGA, you basically apply a fanout solution. You route traces from those fanouts to the perimeter of the device prior to general routing of the...
