Stitching capacitors were added close to the vias that connect reference planes to avoid plane obstructions.

A minimum 3W clearance and 135° trace bends were used for high-speed differential signals.

The operating frequency of the board is 2.5 GHz.Power planes are located between layers 4 and 13.This requires a clearance of 150 mil from the outline of the sockets. Sockets are used to mount the BGAs on the board firmly.Three 0.65mm BGAs surround a 0.4mm pitch BGA placed at the center of the main board.The outputs are tested and measured using these sub-boards. The main board is connected to four daughter boards using connectors.This is a 16-layer board with an outline of 254mm X 190.5mm.HDI PCB design specs with 0.4 and 0.65mm BGAs

We will go over the requirements, the key design limitations, and the methods we used to make the board successful. Some of the challenges that we faced while designing this HDI board with 0.4 and 0.65 mm BGAs are explained in this case study. The smaller the pitch of a BGA, the more challenging it is to break out and route the pins. With a higher pin count, excellent thermal compatibility, and improved current distribution, they are well-adapted to microprocessors, microcontrollers, RAM devices, and display boards.
