Oxydation and female pin headers problems

Hello,

I got failure with my 2 years old geiger station due to contact oxydation and female pin headers problems.

My station was a homebraw diy kit + Arduino with ethernad pad connected with wires. Unfortunately, oxydation started to randomly create contact problems. It was issued with F2 contact spray.

The second problem added many questions about the origin of random working state of my ethernet board. Mainly it's because of femalle pin headers bad quality. If you break a single row square female pin header, you will find the origin of random behaviour in your electronic DIY board.



Wires connected on female pin header quite a long time would increase rate of female pin deformation and lost of contact.

I guess it could be usefull to know that because we find many of this female pin header on the market. Most arduino board are made of.


Best regards

Hum, I have my GMC-200 outside, inside one of them temp/hum radiation shields you use for weather station sensors. I didn't seal up the case of the GMC-200, it is protected by the enclosure and has been running out there since I started here. Maybe I should pull the unit this weekend for the heck of it and check out the electronics just to be sure, but readings have been flawless so far, but still worth a check..
