Placement and orientation of SMD NTC thermistors on PCB
Page 15 of 20
It is recommended that the PC board
should be held by means of some
adequate supporting pins such as
shown left to prevent the SMDs from
being damaged or cracked.
When placing a component near an
area which is apt to bend or a grid
groove on the PC board, it is advisable
to have both electrodes subjected to
uniform stress, or to position the
component's electrodes at right angles
to the grid groove or bending line (see
c) Component orientation).
Choose a mounting position that
minimizes the stress imposed on the
chip during flexing or bending of the
board.
