IC- (Integrated circuits) sorting machine is a kind of special equipment used for testing, classifying and grading IC chips, which is of significances in IC industry. Traditionally, IC- sorting machine is controlled by industry personal computer (IPC), which bears disadvantages such as large size and high cost. By contrast, the control system for IC-sorting machines presented in this paper is based on micro control unit (MCU), which is of relatively high reliability as well as high stability but low cost. First, we gave an outline of the configuration and operation principle of the sorting machine. Second, the input and output (I/O) signals that should be controlled were classified. Last but not least, the control strategy was presented both from the hardware side and the software side. In terms of the hardware design, touch screen was adopted as the human interface device (HID) for the sake of convenience, and isolated power module as well as optical isolated module were applied to improve the anti- electro magnetic interference (EMI) performance; In terms of software design, mechanisms such as multi-task by-turn and timer interrupt delay were adopted to improve the operation efficiency.

Thermal Resistors

Based on the International Electrotechnical Commission standards, the electronic devices in the industrial class (e.g., integrated circuits or batteries) can only operate at the ambient temperature between -40°C and 85°C. For the human-involved regions in Alaska, Northern Canada, and Antarctica, extreme cold condition as low as -55°C might affect sensing electronic devices utilized in the scientific or industrial applications. In this paper, we propose a design and optimization methodology for the self-heating portable enclosures, which can warm up the inner space from -55°C for encasing the low-cost industrial-class electronic devices instead of expensive military-class ones to work reliably within their allowed operating temperature limit. Among the other options, ceramic thermal resistors are selected as the heating elements inside the enclosure. The placement of the thermal resistors is studied with the aid of thermal modelling for the single heating device by using the curve fitting technique to achieve uniform temperature distribution within the enclosure. To maintain the inner temperature above -40°C but with the least power consumption from the thermal resistors, we have developed a control system based on the fuzzy logic controller. For validation, we have utilized COMSOL Multiphysics software and then one prototyped enclosure along with the fuzzy control system. Our experimental measurement exhibits its efficacy compared to the other design options.
