Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov kev tsis ua haujlwm ntawm qhov hloov pauv no thiab nthuav dav qee qhov kev txiav txim siab thaum siv nws.
Technical Parameters
Qhov ntsuas tam sim no ntawmme me micro keyboards5 (2) A txog 25A, thiab qhov ntsuas hluav taws xob yog AC 125V / 250V thiab DC 12V / 24V. Nws cov ntawv pov thawj suav nrog UL, cUL (CSA), VDE, KC, ENEC thiab CQC. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo ntawm qhov hloov pauv no, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas nws cov specifications.
Kev tiv thaiv kev tiv thaiv ntawm micro hloov yog ≤30mΩ (tus nqi pib), thiab cov rwb thaiv tsev tiv thaiv yog ≥100MΩ500VDC. Lub dielectric voltage ntawm tsis txuas terminals yuav tsum yog 1000V / 0.5mA / 60S, thiab dielectric voltage ntawm terminals thiab hlau ncej yuav tsum yog 3000V / 0.5mA / 60S. Qhov hluav taws xob lub neej expectancy ntawm lub hloov yuav tsum yog tsawg kawg yog 50,000 cycles thiab lub neej txhua yam yuav tsum muaj tsawg kawg yog 1,000,000 cycles. Kev ua haujlwm kub yuav tsum nyob nruab nrab ntawm -25 ~ 125 ℃. Qhov hluav taws xob ua haujlwm zaus yuav tsum yog 15 cycles thiab cov tshuab ua haujlwm zaus yuav tsum yog 60 cycles. Nws muaj kev tiv thaiv kev vibration, uas yog, qhov kev vibration zaus yuav tsum nyob nruab nrab ntawm 10 ~ 55HZ, lub amplitude yog 1.5 hli, thiab peb cov lus qhia yog 1H.
Cov kev ceev faj
Txawm hais tias me me micro hloov yog ib qho me me, nws yog ib qho tseem ceeb ntawm txhua yam khoom siv hluav taws xob. Nov yog qee qhov kev ceev faj kom xav txog thaum siv qhov hloov pauv no.
1. Kev ua haujlwm ib puag ncig
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov hloov pauv no yog tsim los rau qhov chaw ua haujlwm tshwj xeeb. Nws yuav tsum tau khaws cia kom deb ntawm qhov chaw ntub thiab plua plav vim cov no yuav cuam tshuam rau nws txoj haujlwm. Qhov zoo tshaj plaws ua haujlwm kub yuav tsum nyob nruab nrab ntawm -25 ~ 125 ℃.
2. Kev sib txuas hluav taws xob
Thaum ua kev sib txuas hluav taws xob, xyuas kom tseeb tias qhov hloov pauv tau txuas raug raug. Cov ntsiab lus txuas yuav tsum tsis muaj plua plav thiab khib nyiab. Nws raug pom zoo tias tsawg kawg 80% ntawm qhov yuav tsum tau them los ntawm solder. Lub vuam kub yog 235 ± 5 ℃, thiab lub sijhawm so yog 2 ~ 3S. Soldering kub tsis kam 260 ± 5 ℃ 5 ± 1S, phau ntawv vuam 300 ± 5 ℃ 2 ~ 3S.
3. Kev tuav ruaj ntseg
Qhov kev hloov no yuav tsum tau ua haujlwm nrog kev saib xyuas thaum lub sijhawm teeb tsa lossis kev saib xyuas. Tsis txhob siv cov khoom ntse vim lawv tuaj yeem ua rau qhov hloov pauv thiab ua rau nws siv tsis tau. Khaws qhov hloov mus kom deb ntawm cov kua thiab cov dej noo, vim tias txhua qhov kev sib cuag tuaj yeem ua rau luv luv thiab cuam tshuam rau nws txoj haujlwm.
4. Kev xeem thiab ntawv pov thawj
Ua ntej siv lub micro hloov me me, thov xyuas kom meej tias nws tau dhau qhov kev xeem cuam tshuam thiab tau txais cov ntawv pov thawj ntawm UL, CSA, VDE, ENEC, TUV, CE, KC thiab CQC.
nyob rau hauv xaus
Micro keyboards yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Nws tswj cov kev khiav ntawm hluav taws xob thiab circuits, kom ntseeg tau tias cov cuab yeej ua haujlwm ntawm nws qhov zoo tshaj plaws. Thaum siv qhov kev hloov no, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev qhia tshwj xeeb xws li kev ntsuas tam sim no thiab qhov hluav taws xob, nrog rau kev ceev faj xws li kev ua haujlwm ib puag ncig, kev sib txuas hluav taws xob, kev ua haujlwm nyab xeeb, kev sim thiab ntawv pov thawj. Los ntawm kev soj ntsuam cov kev ceev faj no, koj tuaj yeem lav qhov kev ua tau zoo tshaj plaws los ntawm qhov hloov me me snap.
