The lifespan of button circuit boards can be prolonged through proper repairs and circuit board maintenance practices. Some things to do when maintaining these systems include:
To avoid excessive wear, ensure that the buttons are pressed correctly. When excessive pressure or wrong angles are applied to the buttons, the circuit board connected beneath it can crack or become damaged. Educate users to apply modest pressure when the buttons are pressed to reduce physical damage over time.
Button circuit boards are normally enclosed to protect them. However, in case of water, dust, or other foreign object penetration, it can cause malfunction. Immediately wipe off spills and clean off any accumulated dust will help preserve the circuit board.
Excess heat, humidity, and extreme cold are all possible hostile environments to circuit board components. Keep their surroundings in a standard acceptable operating range to reduce deterioration.
At times, the solder joints connecting the buttons to the circuit board can crack or weaken, causing misfires or total functionality loss. Checking and re-solder those joints whenever they begin to show wear can prevent this from happening.
Ensure that the circuit board area is free from debris and build-up. This may cause overheating and even hinder functionality.
Periodic inspections mean identifying problems before they escalate. This will also ensure minimal disruption of services.
Frequent testing of these systems can identify malfunctioning components. Further, testing will allow one to replace them in advance without affecting end users.
