Double check soldering.
Usually undetected keypresses on some columns are related to soldering problems. Judging from the YJ-14015 picture it seems a likely cause. I suggest you to use some flux.
Hope this helps.
@mattdibi thanks,I screw up, the pcb panel was broken by my pincers, I need to remake the pcb, It will take one month maybe, I will try again after I receive the pcb and mcu
I am very excited it works, thanks you @mattdibi
I make a redox-wireless keyboard, the right half can work well, but in the left half, three columns can not work, others can work, I don't know how to solve the problem.
