HDI imaging, while achieving low defect rate and high output, can achieve stable production of HDI conventional high-precision operation. For example: advanced mobile phone board, CSP pitch is less than 0.5mm. The board structure is 3 + n + 3, there are three superposed vias on each side, and 6 to 8 layers of coreless printed boards with superimposed vias.The following is about Medical Equipment HDI PCB related, I hope to help you better understand Medical Equipment HDI PCB.
