Clean room 3
Clean room 2
An air controlled environment made with a laminar flow fan ended with an absolute filter is used to check
devices and to make micro-electric bonds. In this room a Leica binocular magnifier is placed to have a
final sight of the device preparation. A suitable bench is there placed to mount devices on their carriers.
The electric and thermal adhesions of the devices are made with silver conductive glue. The electric
connection between the devices and the carrier is making with a Delvotech Wire Bonding Machine. That
bonding machine, using a 25 m thick gold wire, can solder on many metals or semi conductive pads.
That solder is realized with the inter-diffusion of the wire gold atoms in the pad material injecting ultrasound
through the wire-pad interface.
