    Default A little tip when inspecting PCB

    Hi
    Doing visual inspection greatly helps inspecting a PCB for possible failure.

    One of which is mention of bulging capacitor or leaking ones.

    The bulge occurs mostly at the top of the capacitors. However I have come across two capacitors that looked perfectly fine at the top but they had deformation at the bottom.

    If anything is 2007/2008 there was lots of fake capacitor batter going around

    google it.

    Visual inspection is a crucial step in identifying potential issues with a PCB. Bulging or leaking capacitors are indeed common indicators of failure.
