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...
