목록
Pressure sensor sensitive elements are inherently non-repairable due to MEMS technology limitations, irreversible packaging processes, and cost-effectiveness considerations.
기술적 민감도 및 취약성
높은 정밀도
Sensors (e.g. optical, MEMS, pressure sensors) are high-precision components. During transportation or disassembly, external factors such as vibration, static electricity or humidity can degrade or damage their performance.
교정 무효화
Many sensors are professionally calibrated before leaving the factory. Any dismantling or non-professional intervention will destroy the calibration data, and even if reassembled, the original accuracy may not be recoverable.
비용 및 타당성
높은 수리 비용
Repairing sensors requires specialised equipment and environments (such as cleanrooms). The cost of repair may approach or even exceed that of replacing the element altogether.
되돌릴 수 없는 포장
Some sensors employ sealed casings (e.g. submersible pressure sensors). Forcibly opening them destroys the structure and renders them irreparable.
품질 관련 책임 부여의 어려움
사용 위험
Sensors can be damaged by incorrect installation (e.g. over-pressure, reverse polarity) or environmental factors (corrosion, high temperature). Manufacturers find it hard to establish whether a fault is due to product quality or user error, and returns can easily lead to disputes.
업계 관행 및 정책
일회용 디자인
Many consumer-grade sensors (such as the gyroscopes in smartphones) are designed to be non-serviceable, with entire modules replaced rather than individual parts.
리버스 엔지니어링 방지
Some manufacturers adopt “no return, no repair” policies to protect proprietary technology and limit product circulation.
특수 센서 유형에 대한 제한 사항
생화학 센서
Sensors exposed to chemical or biological samples (e.g. medical sensors) may be prohibited from return due to contamination risks.
안전에 중요한 구성 요소
In automotive or industrial applications, repaired sensors may pose reliability hazards. Manufacturers therefore favour complete replacement.
사용자를 위한 권장사항
구매 전 정책 확인
Choose suppliers who offer clear technical support and understand the scope of their warranty.
전문적인 테스트를 받으세요
If you suspect a fault, use the manufacturer’s authorised testing procedures rather than attempting your own dismantling.
모듈 교체를 고려하십시오.
Where feasible, replace the entire sensor module rather than attempting chip-level repairs.
결론
In short, the characteristics of sensor components determine that their after-sales policy is more inclined to “수리 대신 교체”, which is the result of a trade-off between technology, cost and risk.
