The bonder has a graphite heater element enabling fast heating to the melting point of the solder. To prevent oxidation of the solder and bonding surfaces it is possible to have a gas flow of formier gas (4-10% H2 in N2) over the sample. The machine also has a pick-up tool enabling accurate placement of the sample onto a carrier.

The flip chip bonder can be used to place chips on a substrate with high precision. This way electrical contacts can be made between contact pads on the chip and substrate.

<br/>
With a dispensing tool small amounts of solder paste or glue is dispensed on the substrate with high accuracy. The substrate could for example be a printed circuit board (PCB). After some experience with the machine, it is possible to place dots with different shapes and sizes on the surface. With a placement tool a chip can then be picked up upside down and by the use of a camera unit, it is possible to align the contacts on the chip to the solder/glue dots on the on the substrate before joining the two surfaces with a light pressure. The stack is subsequently cured and an underfill glue can be dispensed to enhance the bonding strength between chip and substrate.

Heating Chuck on the Die-bonder

Die bonder (eutectic metal soldering)

The Cammax EDB80 Die bonder is for placing and soldering dies onto a package or substrate.

Section under construction.jpg Will be temporary taken out of service during the PolyFabLab construction.

The bonder has a graphite heater element enabling fast heating to the melting point of the solder. To prevent oxidation of the solder and bonding surfaces it is possible to have a gas flow of formier gas (4-10% H2 in N2) over the sample. The machine also has a pick-up tool enabling accurate placement of the sample onto a carrier.
