A test board suitable for mass testing of the production of CMS RPC link boards has been developed. The test board provides a fast first-level pass of the link boards at the production facility. This ensures that link boards with basic errors are not sent further to the long-term tests at the laboratory. A Field Programmable Gate Array (FPGA) circuit is used to scan connections and shorts of the board traces. The test board functioned well and provided a fast, less than 1 min per board, test at production.
