METHOD OF PREVENTING EMI FOR A FASTENING HOLE IN A CIRCUIT BOARD AND A FIXTURE THEREFOR

摘要

A method of preventing EMI for a fastening hole in a circuit board includes the steps of providing a circuit board which includes a plurality of fastening holes extending through opposite first and second surfaces thereof and a plurality of solder pads disposed on the second surface, each fastening hole being surrounded by the solder pads; disposing an electronic component on the first surface; positioning the circuit board on a fixture such that the solder pads are not covered by the fixture; and wave soldering the circuit board so that the electronic component is fixed to the circuit board and the solder pads are attached with solder materials.
