Abstract
A method of bonding a first plurality of electrical contacts to a second plurality of electrical contacts by aligning the first and second contacts, placing a diaphragm member against the first contacts and applying a differential pressure, such as a vacuum, to the diaphragm in a direction to pull the first contact toward the second contact. Thereafter, the first contacts are bonded to the second contacts with a laser. The diaphragm or a coating on the diaphragm can be a material that absorbs energy from the laser to transfer laser energy to the bond. The diaphragm may be a glass plate or a transparent membrane, may have a support bonded to the first contacts, and may include openings through which the contacts are bonded.
