—LED MOUNTING METHOD
4) When mounting the LED by using a case, as shown Fig.4, ensure that the mounting holds on
the PC board match the pitch of the leads correctly-tolerance of dimensions of the respective
components including the LED should be taken into account especially when designing the
case, PC board, etc. to prevent pitch misalignment between the leads and board holes, the
diameter of the board holes should be slightly larger than the size of the lead. Alternatively, the
shape of the holes should be made oval. (See Fig.4)
