Dear Sir/Madam,

I am going to design a printed circuit board with four Insulated Gate Bipolar Transistors (IGBT) with following specification:

Type: IKW40N120T2
Maximum collector-emitter voltage: 1200V
Maximum DC collector current: 72A
Maximum DC Diode forward current: 72A
Dimension: Shown in the attached file

Please let me know the suitable technique to attach and solder such IGBT to PCB.

The usual way (with solder) and traces sized to handle the current. Allow room for a heat sink if power dissipation will be high enough for one to be required.
Dear Dennis,
How should I connect the collector and emitter legs to the tracks of PCB? Is there a common and reliable procedure?

Depending on power, you will find some that have wider traces on the board. Sometimes with a thickened layer of solder in addition to the trace. Anything greater that that is bolted onto the chassis for grounding/heatsinking and wired using heavier gauge wiring.
