Hearing Aids Manufacturing Process
Component Inspection
We work with world-renowned component suppliers, such as Knowles, Intricon, Sonion, PowerOne
Welding Production
To manufacture a hearing aid, components need to be soldered on the circuit board.
Assembly
Experienced operators assemble different parts into the hearing aid housing.
Inspection
Rounds of inspection will be conducted, including checking appearance, sound quality and other performance.
IQC-Incoming Quality Control
When we receive materials and components, our IQC department first checks their conformity against the inspection criteria. Only qualified materials enter our warehouse. Smaller components are examined through our ultra-microscope.
Welding and Assembly
Once the production department receives the materials, welding and assembly under a microscope begins. Our welding operators are highly skilled and very experienced.
Electrical Test with Fonix
The Fonix test machine makes a sound that is picked up by the hearing aid’s microphone. The hearing aid’s performance is then assessed based on the results displayed on the Fonix screen.
Listening Test
Experienced hearing inspectors wear the hearing aid, as end users do, to test the device for whistling sounds and other noise feedback. The volume settings, program settings, and other functions are also evaluated.
Rechargeability Reliability Test
For rechargeable products, the charging performance is checked. All products are first fully charged; then discharged; and then charged again to ensure that the product has enough power before shipping. The charging time, current, voltage, and other necessary measurements are recorded and checked for irregularities.
Packaging
We have precise packaging guidelines to ensure that our packaging personnel pack strictly per requirement.
OQC-Outgoing Quality Control
Our OQC personnel check the goods according to AQL standards, including the hearing device itself and its packaging.
