Abstract:
An apparatus for manufacturing a circuit board by connecting a first area array component to a substrate, the first area array component disposed upon the substrate, the first area array component and the substrate being joined by joining material, at least a second area array component disposed on the substrate proximate the first area array component, the apparatus comprising:a heat source heating the first area array component and heating the portion of the substrate beneath the first area array component to melt the joining material;a seal, joined to said heat source, sealing against the substrate and isolating the second area array component from the heating of the first area array component;a moveable mechanism urging the heat source into contact with the substrate and restraining warping of the substrate due to the heating of the first area array component and preventing damage to the substrate, the moveable mechanism allowing the first area array component to freely move in the direction of a plane of the substrate under surface tension of the molten joining material during heating to center the first area array component.
