Abstract: PURPOSE: An electrical fabrication and method of forming thereof are provided to reduce strain induced by the heat of the solder ball of a ball grid array module attached to a circuit card by a vacant part substantially surrounding the second section of a dielectric layer, and a pad containing the step positioned above the second section. CONSTITUTION: A solder ball is attached to a circuit card bad, and a BGA module is connected to a circuit card. A circular vacant space of height H1 inside a board surrounds board material under the GBA pad, and a circular vacant space of height H2 inside a board surrounds board material under a circuit card pad. The transformation of heat-induced strain is dispersed to the height H+H1+H2, whereby the strain of the solder ball decreases. This protects the preservability of solder connection, and extends the fatigue life of the BGA module, and further it can be used together with other method with a slight additional cost.
