Common PCB Reliability Issues in Industrial Control Systems?

Hi everyone,

Quick question for those working with industrial control systems what PCB related issues have you seen show up after deployment?
I’m talking about things like vibration related faults, connector problems, solder fatigue near power components, or heat issues inside panels.

Sometimes everything passes testing, but real-world conditions tell a different story.

Would love to hear any field failures or lessons learned that caught you by surprise.
