Product Name: A communication board
Technical difficulties: the product of the main chip XC7VX690T nearly 2000 Pin, 9 DDR3, a total of more than 200 pairs of 5G differential signal, more than 400 pairs of 1G differential signal. A wide range of power supplies. Space-intensive, thickness limit layer.
Solution: Combine the factory process, reasonable layout planning, adjust the network so that the signal connection is relatively smooth, SI simulation support; finishing summary of a variety of power supply, especially under the power supply board, consider the cooling design thoughtful. Ultimately, our PCB design, PCB production and welding, took less than 4 weeks to complete all the work. Customers on the Division I provided samples, one-time debugging success.
