Method for reducing die attach defects by using a foreign
Disclosed is a method for reducing die attach
defects by using a foreign material blower. Benefits include improved yield
because defects are reduced.
disclosed method reduces die attach defects caused by the presence of foreign
material (FM) on the die. A blower activates when foreign material is
encountered. The blower is comprised of a tygon tube connector and a hose
implement the method, perform the following steps:
1. Connect the nozzle to the tygon tube.
2. Put the hose connector at the other end of the tube.
3. Install the blower with nozzle pointing towards the die
that is to be pick-up by the pick and place.
4. Connect the other end of the tube with the connector to
the air supply.
advantage of the disclosed method is that it automatically blows away any
foreign materials floating on the die, reducing defects caused by FM. As a
result, die attach yield improves. No conventional solution provides this
is the foreign material hose blower pointing to the die to be pick-up that
will help eliminate floating FM.
