Multi-layer HDI PCB BGA assembly combines the most advanced printed circuit board technology with the most demanding surface mount component type, requiring precision manufacturing capability that spans the PCB substrate characteristics, the component placement requirements, and the soldering process control. Multi-layer PCBs with HDI technology provide the interconnection infrastructure for BGA components where the hundreds or thousands of connections from each BGA package must be routed through the PCB layers to connect with other components, power planes, and ground planes. The number of PCB layers required for a BGA design is determined primarily by the BGA ball count and pitch where higher ball count and finer pitch BGAs require more layers and HDI microvia technology to route the fan-out connections, with a typical 0.8mm pitch 484-ball BGA requiring 6 to 8 layers while a 0.5mm pitch 1156-ball BGA may require 10 to 14 layers with HDI build-up construction. The precision SMT assembly of multi-layer HDI PCBs with BGA components requires addressing the interaction between the PCB characteristics and the assembly process. Multi-layer HDI PCBs with their thin dielectrics, multiple copper layers, and plated microvia structures have different thermal characteristics than standard PCBs including higher thermal conductivity through the board thickness due to the dense copper content and faster heat dissipation during reflow soldering, requiring reflow profile adjustments to ensure all BGA solder balls reach the proper reflow temperature. The flatness of multi-layer HDI PCBs is critical for BGA assembly because any board warpage during reflow causes the BGA ball array to lose coplanarity with the PCB pad array resulting in open joints, and HDI boards with asymmetric copper distribution may be more prone to warpage requiring process controls including optimized board support during reflow. Additionally, the fine surface features of HDI PCBs including small pads and tight spacing demand the highest solder paste printing precision and SMT placement accuracy. Multi-thickness copper capability supports HDI stack-ups with different copper weights on different layers while three surface finishes provide optimal BGA pad surfaces.
