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.

Background

� � � � � 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.

General description

        � � � � � 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.

        � � � � � The key elements of the method include:

•        � � � � Fiber optic cabling

•        � � � � IR heater element

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved reliability due to the improved placement accuracy of a die placement machine because excess heat does not occur in the enclosed environment

•        � � � � Improved functionality due to providing a very efficient means of transmitting IR heat to a localized area without excess heat...
