Conveyor oven profiler with simplified temperature sensor connection scheme

摘要

A sensor link is disclosed that simplifies connections between multiple temperature sensors positioned on a test board and a data logger that stores temperature information received from the temperature sensors while passing through the conveyor oven. In one embodiment, the sensor link includes multiple input ports for connecting to the temperature sensors. Conductors within the sensor link connect the multiple temperature sensors to an output port. In one aspect, a single cable extends between the sensor link and a data logger. The data logger stores temperature information received from the temperature sensors while the test board is passed through a conveyor oven. The sensor link can also have additional temperature sensors for providing additional temperature information about the conveyor oven. For example, an ambient temperature sensor may be positioned on the sensor link to provide the ambient temperature of the conveyor oven. A metal mass may also be positioned on the sensor link for providing heat flow information about the conveyor oven. Once all of the desired information is stored in the data logger, such information can be downloaded to a computer for further processing, such as obtaining a profile of the conveyor oven.
