Method for the use of fiber optic cabling to focus an IR
heating element for under-board heating
Disclosed is a method for the use of fiber optic cabling to
focus an infrared (IR) heating element for under-board heating. Benefits
include improved reliability and improved functionality.
� � � � � Excess heat is generated by IR heaters in an enclosed
environment, which affects the placement accuracy of a die placement machine.
� � � � � Conventionally, other methods of under-board heating are used.
Solutions include forced heated air, IR heaters that radiate heat throughout
the machine enclosure, and contact heaters.
� � � � � Fiber optics is extremely efficient at sending the light
spectrum over great distances with little loss in effective strength. IR is a
form of light radiation. It passes through the fiber optic cable and provides
near equal heat at the end.
� � � � � The disclosed method is fiber optic cables
connected to an IR heating element. One end of each cable is placed underneath
a substrate. The cable provides a conduit for IR heating.
