Ib txoj hauv kev yooj yim dua los Siv Cov Hlau Hlau Hlau Hlau rau SMD LEDs

Cov Lus Qhia no piav qhia txoj hauv kev yooj yim dua ntawm kev txuas cov hlau nplaum zoo rau saum-teeb LEDs. Nws yog nyob rau hauv cov lus teb rau Lub Tsiaj ntawm Cov Hluav Taws Xob qhia uas qhia pom siv "pab txhais tes" clip los ua txoj haujlwm no. Kuv xav tias kuv txoj kev yooj yim dua.

Kauj ruam 1: Ua Jig

Qhov nyuaj tshaj plaws ntawm kev siv tshuaj txhuam rau cov ntu no yog tuav lawv. Yog li cia peb ua jig los tuav cov ntu. Kuv pib nrog ib daim duab los qhia (daim duab los tiag, piv txwv li ib txheej) los ntawm ib daim ntim. Tsis txhob siv cov ntawv ntawv corrugated ntawm cov khoom siv los ua cov thawv xa khoom Kuv txiav kuv li 3 daim tom qab pom tias cov tuab ntawm cov duab los qhia (0.44mm) yog li 1/3 qhov siab ntawm LED (1.5mm) uas kuv tau sim rau solder. LED ntawm no yog 1206 ib feem, tab sis qhov no yuav ua haujlwm rau ntu me me ib yam nkaus. Qhov ib qho yuav dhau los ua ib txheej ntawm jig, nrog lub qhov nyob hauv txhua ntawm ob txheej saum toj los tuav lub LED. Ua ntej, txiav lub qhov hauv ob ntawm daim nrog rab riam hobby ntse. Lub qhov yuav tsum tsuas yog loj txaus los tuav LED nrog qhov nqes me me. Daim ntawv hauv qab tsis muaj lub qhov, thiab tiv thaiv cov LED los ntawm kev hla. Tom qab ntawd laminate cov khoom ua ke siv cov kua nplaum, ua kab hauv qhov ob sab saum toj. Nias kom txog thaum cov kua nplaum tau teeb tsa nrog koj cov ntiv tes lossis phau ntawv hnyav.

Kauj Ruam 2: Npaj Cov Hlau Hlau

Npaj Cov Hlau Hlau

Tam sim no koj yuav tsum tau txais cov hlau nplaum hlau nyob rau hauv qhov chaw thiab npaj kom muab tshuaj txhuam. Kuv siv cov xaim uas tuaj yeem hle tau siv cov hlau txuas, tab sis koj yuav xav tau txhawm rau rwb thaiv tsev ntawm lwm hom hlau. ntsuas tawm ib daim hlau uas ntev li 2cm ntev dua ob zaug qhov koj tab tom sim ua (piv txwv tias koj xav kom ob lub xov hlau tawm hauv tib txoj kev). Khoov cov xaim ntawm nws qhov chaw mus rau hauv lub voj uas nws txoj kab uas hla yog hais txog LED dav, thiab kaw kab uas tsis yog lub voj kom lub voj yuav nthuav tawm tsuas yog yav dhau los LED thaum nws tau kaw cia ib yam nkaus. rwb thaiv tsev) thiab cov tin (siv cov kab laug sab yog li nws tau npog qhov liab qab ntawm cov xaim) cov xaim uas nws yuav txuas nrog LED. Yog tias koj siv rab riam los xaim hlau, sim nrhiav lub ntsej muag tsis zoo thiab rub nws raws cov xov hlau ntawm lub kaum ntiav kom koj tsis txhob xaim lub xov tooj nws tus kheej (uas tuaj yeem ua rau xaim tawg). Yog tias koj siv cov ntawv xuab zeb, qhwv nws ib ncig ntawm tus pas nrig lossis quav nws kom koj tsuas muaj cov ntawv me me hu rau cov xov hlau (ua lwm yam lus, tsis txhob hle ntau tshaj qhov koj yuav tsum tau thiab tsis ua rau xaim puas tsuaj. Txawm hais tias daim duab no qhia pom LED nyob hauv qhov chaw, yog tias koj tab tom khawb koj tej zaum xav tos kom ntxig rau LED kom txog thaum tom qab koj siv cov ntawv xuab zeb lossis riam los npaj xaim. Hauv thawj daim duab, Kuv tau siv kuv cov hlau txuas los hle thiab xaim cov hlau tom qab kuv kaw nws hauv lub voj voos Yog tias koj tab tom muab cov no tso rau hauv cov kab sib txuas, tsuas yog xev xaim xaim kom nws hla cov LED hluav taws xob, tsis yog ua lub voj nyob hauv cov hlau.

Kauj Ruam 3: Ntxig lub LED thiab Muab Cov Hlau Txuas rau Nws

Tam sim no muab cov LED tso rau hauv lub qhov hauv koj lub jig, yog tias koj tsis tau ua dua. Tsis txhob thab nrog polarity yog tias koj siv txoj kev voj, vim ob qho kawg yuav zoo ib yam nkaus. Yog tias koj tab tom ua txoj kab sib txuas, muab cov LED tso rau hauv lub qhov kom raug (sab laj cov ntawv xov xwm rau koj LED rau lawv li cas lawv cim qhov sib txawv, lossis siv koj lub ohmmeter ntawm "diode" ntau yam kom pom qhov twg yog anode (nws yuav yog + tus coj thaum lub ntsuas ntsuas pom ib yam dab tsi uas tsis yog qhib Circuit Court). Tom qab ntawd kaw daim kab xev lossis lwm qhov kawg ntawm xaim kom qhov uas koj tau hle thiab thim tawm yog tiv thaiv cov LEDs. Rub me ntsis ntawm qhov kawg ntawm xaim. Nco ntsoov tias tsis muaj (lossis tsawg kawg tsawg heev) qhov nruab nrab ntawm cov xaim thiab LED. Tam sim no siv ob lub ua ke los siv cov hlau zoo thiab cov rosin me me. Koj yuav xav siv me ntsis ntawm rosin flux ntawm cov ntaub qhwv.

Kauj Ruam 4: Txiav Cov Hlau thiab Tshem Tawm LED

Thaum koj tau xaim cov hlau, siv rab riam hobby ntse los txiav qhov feem ntau ntawm cov xaim. Or yog tias koj muaj ib khub ntawm cov txiav zoo koj tuaj yeem siv lawv, thiab txo txoj hauv kev txiav rau hauv jig. Tab sis txij li jig tsuas yog ib daim duab los xwb, yog tias koj rhuav lub jig koj tuaj yeem ua lub qhov tshiab … Yog tias koj tau siv lub voj, qhov feem ntau yog lub voj nws tus kheej; yog tias koj tau siv hla cov hauv qab ntawm LED rau cov kab sib txuas, ntu ntawd yog ib feem ntawm ob qho khoom siv hluav taws xob LED. Nias ncaj qha nrog rab riam ntse kom txog thaum koj hla xaim. Tom qab ntawd tshem daim kab xev.

Kauj Ruam 5: Twist Cov Hlau (yog tias Koj Xav Tau) thiab Kos Polarity

Thaum kawg koj yuav tsum paub tias cov hlau lead ntawm LED yog qhov twg. Kuv xav pom zoo kom kos ib qho txhuas (ib qho zoo/anode lossis tsis zoo/cathode) ntawm txhua LED lossis cov saw uas koj tab tom siv yog li koj yuav tsis tau txiav txim siab nws tom qab. Yog tias koj cuam tshuam rau tso LED hauv ib qho tshwj xeeb kev taw qhia thiab yog li paub qhov polarity, koj tuaj yeem kos tus +/anode xaim los ntawm kev ua raws cov xov hlau los ntawm qhov paub qhov kawg ntawm LED. Ntxiv rau, koj tuaj yeem siv koj lub ohmmeter los txiav txim seb cov hlau lead twg yog tom qab koj ntswj cov xov ua ke. Yog koj xav tau, koj tuaj yeem ntswj cov xov hlau ua ke. Txoj kev yooj yim tshaj plaws los ua qhov no yog tuav txhua tus xaim ntawm tus ntiv tes xoo thiab tus ntiv tes xoo ntawm txhua txhais tes thiab ntswj ob lub xov hlau nyob hauv tib qho kev taw qhia tib lub sijhawm. Yog tias koj muaj tib lub xov tooj LED txuas rau ob lub xov hlau (tsis siv txoj hlua) koj tso koj lub ohmmeter ntawm "diode" ntau (xub nrog lub cim cim bar) thiab txuas rau ob lub xov hlau los ntawm LED mus rau ob lub ntsuas ntsuas lossis ntsuas, koj yuav tsum pom qhov qhib qhib qhia nyob rau hauv ib qho kev taw qhia (ntawm kuv lub ntsuas, nws nyeem 0L), thiab lwm yam hauv lwm txoj hauv kev. Qhov kev ntsuas diode feem ntau qhia pom qhov poob qis rau pem hauv ntej hla lub diode ntawm qhov qis tam sim no. Yog li hauv qhov no, Kuv pom tias kuv cov LED muaj qhov txuas hluav taws xob tom ntej ntawm 1.836 volts ntawm qhov ntsuas tam sim no (qhov no yog cov laus heev thiab tsis muaj txiaj ntsig LED; raug liab lossis ntsuab LEDs yuav tsum nyeem ib puag ncig 1.4V txog 1.7V). Thaum koj pom qhov ntsuas tsis dhau ntawm koj lub ntsuas, nyeem/ntxiv rau txhuas yuav txuas nrog qhov zoo/anode txhuas ntawm LED. Kos ib qho ntawm cov LEDs (qhov no, kuv tsuas yog khoov cov hlau lead anode ntawm LED; hauv lwm qhov kuv tau siv lub ntsej muag dub ntse los cim qhov tsis zoo/cathode txhuas ntawm LED). Koj tuaj yeem pom ntau lub teeb ci ib yam thaum koj tau txais nws nqes mus rau qhov yog, zoo li hauv daim duab no.
