Hi @taile ,

Maybe a bit desperate but have you thought about filling the gap with conductive glue - info only?

这个答案有帮助吗？

Thank you for your advice!

This is a good idea. However the gap is very small, i afraid the conductive glue will spread out and make short circuit for RAM and CPU and the pin will stick/fix to plastic, affect to RAM when insert to the socket.
