Such cracks are progressively enlarged by repetitive stress until they cause partial or complete delamination of the pad from the PCB laminate. It will create a &#8220;crater&#8221; effect and compromise the connection without any visible signs on the surface. This leaves a solder joint that is weak and can still look good on the outside, but fails when put under electrical or mechanical stress. This process is accelerated by stress factors like PCB bending, drop impact during handling, or high-temperature cycling. Pad cratering may be considered a hidden reliability risk since the damage often propagates below the surface.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div
