Strain Relief Hardware mounting directions 13.79mm [0.543"] 5.03mm [0.198"] If the target board can be designed to accomodate the strain relief hardware, layout the PCB with the pattern shown on the right. The layout shows the location of non-plated holes through the board relative to the QFN land pattern. If holes can not be added to the target board, the screws can be used as standoffs and sit on the top surface of the target PCB.
