Compression Spring Mount |
 |
|
The contacts of these motor are not designed to be soldered. These motor are designed to lay against or directly above the PCB. A downward force is applied to compress the spring contacts against PCB contact pads. It is recommended that these pads be gold plated to improve reliability. To be successfully used, the motors contacts must be properly located directly above the PCB pads. Some recommended options for doing this include, fabricating a silicon rubber pad with a cut out for the motor. Recesses are designed under the pad to accommodate the profiles of all the other parts that lie beneath it. When the product housing is closed, it will exert a downward pressure on the motor ensuring properly spring compression and electrical contact. Alternately, a pocket may be created in the plastic cover (shell) of the products housing to hold the motor. Most motors are available with a rubber boot that will help retain the motor in this pocket. When the cover is closed, the contacts mate with the pads on the PCB. This is the preferred method of using this type of motor as it keeps the vibration off the PCB. This is desirable as vibration is detrimental to the reliability of other components on the PCB. Additionally, more of the vibration energy is likely to be transmitted to the user when the motor is situated in the products shell as opposed to the PCB where it can be dampened. |
