SMT yog dab tsi?
SMT, lossis thev naus laus zis mount saum npoo, yog ib txoj kev siv tshuab uas txuas cov khoom siv hluav taws xob ncaj qha rau ntawm qhov chaw ntawm lub rooj tsavxwm luam tawm (PCB). Txoj hauv kev no tau nrov zuj zus vim nws muaj ntau yam zoo, suav nrog lub peev xwm siv cov khoom me me, ua tiav cov khoom ntom ntom ntau dua, thiab txhim kho kev ua haujlwm tsim khoom.
SMD yog dab tsi?
SMD, lossis Surface Mount Device, yog hais txog cov khoom siv hluav taws xob uas tsim tshwj xeeb rau kev siv nrog SMT. Cov khoom no tau tsim los txuas ncaj qha rau ntawm PCB nto, tshem tawm qhov xav tau kev txuas los ntawm qhov qub.
Piv txwv ntawm cov khoom SMD suav nrog resistors, capacitors, diodes, transistors, thiab integrated circuits (ICs). Nws qhov me me ua rau muaj cov khoom ntom ntom ntau dua ntawm lub rooj tsavxwm circuit, ua rau muaj kev ua haujlwm ntau dua hauv qhov chaw me dua.
Qhov txawv ntawm SMT thiab SMD yog dab tsi?
Nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm cov thev naus laus zis ntawm lub ntsej muag (SMT) thiab cov khoom siv ntawm lub ntsej muag (SMD). Txawm hais tias lawv muaj feem cuam tshuam, lawv cuam tshuam nrog ntau yam ntawm kev tsim khoom siv hluav taws xob. Nov yog qee qhov sib txawv tseem ceeb ntawm SMT thiab SMD:
Kev Txheeb Xyuas
Txawm hais tias SMT thiab SMD yog cov tswv yim sib txawv, lawv muaj feem cuam tshuam ze. SMT txhais tau hais tias cov txheej txheem tsim khoom, thaum SMD txhais tau hais tias hom khoom siv hauv cov txheej txheem. Los ntawm kev sib koom ua ke SMT thiab SMD, cov chaw tsim khoom tuaj yeem tsim cov khoom siv hluav taws xob me dua, me dua nrog kev ua tau zoo dua. Cov thev naus laus zis no tau hloov pauv kev lag luam hluav taws xob, ua rau muaj cov xov tooj ntse zoo nkauj, cov khoos phis tawj ua haujlwm siab thiab cov khoom siv kho mob siab heev, ntawm lwm yam kev tsim kho tshiab.
Nov yog daim ntawv teev peb lub SMD Reflow Motor:
| Cov Qauv | Loj（mm) | Qhov Voltage Ntsuas（V) | Tam sim no ntsuas（mA) | Ntsuam xyuas（RPM) |
| LD-GS-3200 | 3.4 * 4.4 * 4 | 3.0V DC | 85mA Max | 12000 ± 2500 |
| LD-GS-3205 | 3.4 * 4.4 * 2.8 hli | 2.7V DC | 75mA Max | 14000 ± 3000 |
| LD-GS-3215 | 3 * 4 * 3.3 hli | 2.7V DC | 90mA Max | 15000 ± 3000 |
| LD-SM-430 | 3.6 * 4.6 * 2.8 hli | 2.7V DC | 95mA Max | 14000 ± 2500 |
