| Soldering |
|
The sealed miniature sound transducers by Star should not be exposed to extremely high temperatures for prolonged periods of time. As excessive heat will degrade the sealing performance of the unit, soldering should be conducted as quickly as possible. |
| |
Recommended temperature and for soldering
|
250°C ……… within 5 seconds
350°C ……… within 1.5 seconds |
|

|
| Washing |
|
(1)Washable type transducers.
Along with other electronic components, these trancducers may be washed with cleaning solvents after the soldering process. |
| |
(2)Non-washable type transducers.
Subsequent mounting is recommended to avoid to be washed. If it is inevitable to wash a transduser, take necessary measures to prevent washing fluid from entering into the transducer. And it is also required to ensure wellventilation to avoid any undesirable effects by the component substances of the flux that may otherwise remains in the atmosphere. |

Conditions for cleaning
|
Cleaning solvent ……… Deionized water
Solvent temperature ……… 55 ± 5°C
immersion time ……… 5 ± 0.5minutes |
