I made my first batch of 6-layer PCBs. On some of the boards I got a solder bridge on an MCU - I know I need to improve my design, my solder mask, and my mounting method.
Usually on 2- or 4-layer PCBs I don't have any problems removing solder bridges with braid and flux, but on this 6-layer PCB it's nearly impossible. I have a lot of difficulty heating the area and it cools almost immediately. My solder "sticks" on the pin or on the pad and forms aggregates. Do you have any tricks to rework a 6-layer PCB ? Do I need a a heating table? Please help me to find a solution to save my board.
