Consequence of tin droplet on the SPIN debugger connector

General

Dear OwnTech community,

I’d like to get your diagnostic for this strange accidental situation where a SPIN board received a tin (solder) droplet on its STLINK debugger connector.

Here is a picture:

It seems that the 6 bottom pins are electrically connected. Comparing with the SPIN pinout, this translates into 4 pins (2 are not connected):

  • GNDDetect
  • STLINK_RX
  • SWDIO
  • SWDCLOCK

Question: what should be the theoretical consequences of it?

I can only bring the practical consequence I observed: device doesn’t respond on USB port. Is this to be expected?
