Kev ceev faj ntawm Smd Tactile Hloov

Thaum peb siv SMD hom tact hloov, yuav muaj ntau yam teeb meem, thiab qee qhov chaw uas peb feem ntau tsis quav ntsej txog kev siv; Cov hauv qab no yog qhia, yog qhov nto mount tact hloov cov teeb meem tshwm sim thiab yuav tsum tau them sai sai rau thaum siv.

1. Thaum vuam cov terminals ntawm SMD tact hloov, yog hais tias load yog siv rau lub terminals, tej zaum yuav muaj loosening, deformation thiab hluav taws xob deterioration vim txawv tej yam kev mob. Thov xyuam xim rau qhov no thaum siv.

2. Thaum siv cov ntawv luam tawm los ntawm lub qhov rooj thiab cov laug cam uas tsis yog cov lus pom zoo, vim muaj kev cuam tshuam ntawm thermal stress, thov ua kom tag nrho cov kev pom zoo ntawm vuam tej yam kev mob ua ntej.

3. Thaum vuam ob zaug, thov ua nws tom qab thawj qhov vuam yog rov qab los rau hauv chav sov. Cov cua kub tsis tu ncua tuaj yeem ua rau peripheral deformation, xoob terminals, poob tawm thiab txo cov yam ntxwv hluav taws xob.

4. Rau qhov kev teeb tsa ntawm vuam, nws yog ib qho tsim nyog kom paub meej tias qhov tseeb ntawm cov khoom siv ntau lawm.

5. cov khoom tsim thiab tsim nyob rau hauv qhov chaw ntawm DC kuj load. Thaum siv lwm yam loads [inductive load, capacitive load], thov paub meej tias nyias.

6. PCB mounting qhov thiab hom, thov xa mus rau qhov pom zoo me me sau rau hauv cov khoom kos duab.

7. Tactile SMD momentary hloov thov siv rau kev ua haujlwm ncaj qha los ntawm tib neeg raws li tus qauv ntawm qhov hloov. Tsis txhob siv rau kev sim ntsuas kev ua haujlwm.

8. Smd tactile hloov kev ua haujlwm, yog tias qhov teev teev tau siv, qhov hloov pauv yuav puas. Thov ceev faj tsis txhob siv lub zog ntau dua li teev nyob rau ntawm qhov hloov.

9. Thov tsis txhob nias qhov ua haujlwm ntawm sab.

10. Nias qhov chaw nruab nrab ntawm qhov hloov mus kom deb li deb tau rau lub tiaj tus ncej. Rau cov txheej txheem hinged, nias txoj hauj lwm ntawm lub ncej yuav txav thaum nias, thov ua tib zoo saib xyuas.

11. Tom qab lub tactile hloov tau ntsia, thov hu rau tus neeg thaum nws dhau los ntawm lub tshav kub cia hardening rauv vim lub binder hardening ntawm lwm qhov chaw.

12. Yog hais tias cov khoom nyob ib ncig ntawm lub switches tsim corrosive gas, nws yuav ua rau phem kev sib cuag thiab lwm yam phenomena, yog li thov ua kom tiav kev pom zoo.

13. Carbon contact point muaj cov yam ntxwv ntawm kev sib cuag tiv thaiv kev hloov vim lub laub load. Thaum nws yog siv nyob rau hauv voltage division Circuit Court, thov siv nws tom qab tag nrho kev pom zoo.

14. Rau cov qauv uas tsis yog hom kaw, thov ua tib zoo saib xyuas qhov ntxeem tau ntawm lub cev txawv teb chaws
