Investigation of Overprinting BGA Pads
The added benefit of using overprinting stencil design strategy is that this should compel further improvement in paste transfer efficiency and uniformity by raising its area ratio. In this study the circle shape overprint apertures were designed for 0.5mm pitch BGA land patterns that measured to an area ratio value of 0.70.
