Board one for chan 1-2 looks ok with propper domes and shine. Board two is god awful with gray joints and a lot without enough solder or heat when made. You can literally see that the solder didn't bead around the pin as it's only on one side and you can actually see down into the PCB on one side of the pin where there is no solder! Boards 3 and 4 are 50% success rate pin to pin on the solder job! I'M SO UPSET AGAIN!
