客户出货2k,发现4片异常,LPC1754FBD80 60脚 TX对地短路;个别的海有51脚RTS1脚对地短路,请问量产出货的出现此问题,大概是什么原因造成的
The customer shipped 2k, found 4 abnormal, LPC1754FBD80 60-pin TX to ground short circuit; There is a short circuit of Pin 51 RTS1 to the ground in some individual sea. May I ask what is the cause of this problem in mass-produced goods.
