Rotation of the distribution pump array allowing simultaneous distribution on multiple electronic substrates by multiple distribution pumps

摘要

The method of dispensing a material includes delivering an electronic substrate to a dispensing location. The electronic substrate has at least two identical patterns and at least two fiducial marks. The method captures at least one image of at least two reference marks provided on the electronic substrate, analyzes the at least one image to determine the position of the electronic substrate in the X-axis, Y-axis, and θ directions, and the electronic substrate The method further includes calculating the rotation angle of and rotating the distribution pump array to match the angle of the electronic substrate. Alternatively, the electronic substrate can be rotated to match the angle of the distribution pump array.
