Abstract:
A method for die bonding includes positioning a dispenser in a die bonding apparatus, wherein the dispenser includes a reservoir having bonding adhesive therein including particles and a liquid carrier. The dispenser is moved to provide mechanical agitation to the dispenser for mixing the bonding adhesive into a homogeneous mixture of particles and the liquid carrier, wherein the bonding adhesive is not dispensed during moving. After the moving, the bonding adhesive is dispensed onto a bonding location on the workpiece without removing the dispenser from the die attach apparatus. An integrated circuit (IC) die is attached onto the bonding adhesive over the bonding location. The method can also include determining an amount of time elapsed after the last mixing of the bonding adhesive or the positioning of the dispenser in the die bonding apparatus, and automatically initiating movement for mixing only if the elapsed time exceeds a predetermined time.
