An apparatus and method for selecting and dispensing coverglasses over specimens on slides for the purpose of viewing specimens through a microscope. The selecting device contains suctioning mechanisms for picking up a coverglass from a stack of coverglasses. It also contains the ability to shape the coverglass to assist in separating and laying down of the coverglasses with a reduction in the creation of bubbles in the fluid.

Automated coverslipper and methods of use

The array of recesses in a ball grid array carrier or (device) are populated with solder balls through a closely spaced tooling plate or stencil which has a like array of apertures. A solder bin is moved along side rails over the stencil allowing solder balls to fill the apertures in the stencil settling on the corresponding recesses and held there by adhesive. Excess solder balls are moved along by the movement of the bin. The bin is held in close contact with the stencil to avoid misplacement of the balls by bowing the stencil and by forcing it into a plane coplanar with the bottom of the bin. Alternative techniques are magnetic or vacuum areas of the bottom of the bin to ensure complete contact with the stencil.
