A mounting device for chips has a heat sink and at least one clamp. The
heat sink has at least one conductive side, two ends, multiple chip units
and two connecting bases. The chip units are arranged on the at least one
conductive side. The connecting bases are formed on the ends of the heat
sink. The at least one clamp is mounted across the at least one
conductive side of the heat sink and has two ends, a middle sheet,
multiple pressing tabs and two connecting arms. The pressing tabs extend
from the middle sheet to press the chip units against the conductive side
of the heat sink. The connecting arms are formed respectively on the ends
of the clamp and are mounted respectively on the connecting bases.
