PC board
When the surface of a PC board on which the Thermistors have been mounted is coated with resin to protect
against moisture and dust, it shall be confirmed that the protective coating does not influence the reliability of the
Thermistors in the actual equipment.
(1) Do not use coating materials that are corrosive or chemically active.
(2) Do not use coating materials with large thermal expansivity to prevent damage to the Thermistors during the
(1) Abnormal and excessive mechanical stress such as bending or torsion
(2) Dividing/Breaking of the PC boards shall be done carefully at moderate
(3) Examples of PCB dividing/breaking jigs:
(1) The Thermistors shall be free from any excessive mechanical impact.
(2) When handling PC boards with Thermistors mounted on them, do not allow
curing process.
shown below can cause cracking in the Thermistors.
speed by using a jig or apparatus to prevent the Thermistors on the boards
from mechanical damage.
The outline of PC board breaking jig is shown below.
It is recommended when dividing or breaking PC boards that they are held near the jig where no bending will
occur, this way there will be no compressive stress applied to the components or Thermistors on the PC board.
Do not hold the PC board at a position which is far away from the jig, tensile stress to the Thermistors may
cause them to crack.
The Thermistor body is made of ceramics and may be damaged or cracked
if dropped.
Never use a Thermistor which has been dropped; their quality may be
impaired and failure rate increased.
the Thermistors to collide with another PC board.
When mounted PC boards are handled or stored in a stacked state, impact
between the corner of a PC board and the Thermistor may cause damage
or cracking and can deteriorate the withstand voltage and insulation
resistance of the Thermistor.
