Patent number: 11686759Abstract: Systems and methods for testing printed circuit boards (PCBs) are disclosed herein. In one embodiment, a tester for printed circuit boards (PCBs) includes a test fixture having a plurality of electrical contacts for contacting the PCBs that are units under test (UUTs). The test fixture carries a remote test peripheral master (RTPM) module, and a remote test peripheral slave (RTPS) module. The RTPM module and the RTPS module are connected through a remote test peripheral (RTP) bus.Type: GrantFiled: February 18, 2022Date of Patent: June 27, 2023Assignee: CheckSum, LLCInventors: Jonathan Allen Feucht, Peter Andrew Pias, Daniel Benjamin Carson

Patent number: 7802021Abstract: Embodiments of the present invention relate to machines that perform in-system programming of programmable devices that are attached to assembled printed circuit boards. In accordance with one aspect, multiple nonvolatile devices may be programmed in a single session at their normal maximum programming speeds. Different nonvolatile devices on a board can receive different data. Data variables can be inserted so that not all boards receive identical data. A master controller sends image files and algorithm information to a subsidiary controller. The subsidiary controller executes a device algorithm, and an FPGA executes a bus algorithm. Embodiments of the present invention can be designed as stand-alone systems or to operate cooperatively with an automatic tester, so that testing and device programming can take place in a single operation using a single fixture to hold the circuit board.Type: GrantFiled: January 29, 2009Date of Patent: September 21, 2010Assignee: CheckSum, LLCInventors: Daniel Benjamin Carson, Hans Frederick Ashlock, Sidney Clayton Fluhrer, Peter A.
