LASER ASSISTED BONDING MACHINE
The majority of today’s Flip chip bonders are derived from modified surface mount equipment. This method of flip chip attach uses thermal energy to reflow the bumped chip to the substrate. The advantage of laser heating instead of direct thermal heating is given by high selectivity with an extremely good time control in the millisecond time range. This is in contrast to infrared and convection ovens where the assembly process takes minutes. By using the laser to reflow the solder bumps, the thermal stress induced in the package and on the substrate is minimized allowing implementation of new substrates and new IC’s which are thermally more sensitive.
