Abstract:
A microelectronic package having integrated circuits is provided. The microelectronic package includes multiple dielectric laminate layers, copper circuitry between the dielectric laminate layers where the copper circuitry includes circuit traces, and ball grid arrays/land grid arrays operatively connected to the copper circuitry such that conduction occurs. Further, proximate to the connection of the copper circuitry and the ball grid arrays/land grid arrays, a protective copper tongue is below an extension of the circuit traces, such that the protective copper tongue prevents the circuit traces from being affected by cracking propagated in the dielectric laminate layers or the ball grid arrays/land grid arrays.
