Why does hitting ELECTRONIC things sometimes fix them?
In: Technology
This applies more to older electronics. It’s due to microscopic cracks and connections with oxide layers on them. Hitting it can cause enough of a shock to either shut such a microscopic crack, or scrape away a tiny bit of oxide. This is basically the equivalent of cancer in electronics in that if nothing else kills it, solder joint cracks will. It’s just a matter of time and how exposed the electronics is to temperature fluctuations, humidity etc.
