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...
