Mastering 0.4mm Fine-Pitch BGA Design: A Guide to Avoid Costly Manufacturing Failures

​ 0.4mm fine pitch BGA PCB layout showing pad design and routing for dense SMT assembly

Nowadays, more and more precise electronic components are widely used in some advanced electronics devices, such as fine pitch FPGA component from Xilinx. But accordingly this take extra challenges to PCB designer and PCB manufacturing’s capability when the design has many limits in spacing of tracks, plated holes, electronics performance, etc.
