Yuav Ua Li Cas Ua Teeb Pom Kev Pom Qhov Muag LED: 6 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Kuv tau siv lub qhov muag tsom rau saib cov khoom siv hluav taws xob me me, tshuaj xyuas PCBs thiab lwm yam. lub qhov muag zoo tib yam rau lub teeb pom kev zoo LED qhov muag. Tom qab kuv ua ib qho, Kuv xav tsis thoob tias qhov khoom zoo li cas zoo dua vim lub teeb pom kev zoo.

Kauj Ruam 1: Cheebtsam thiab Cov Cuab Yeej

Cheebtsam: 1. SMD Dawb LEDs PLCC pob - 8 tus lej 2. SMD Resistors 100 Ohm 1206 lossis 0805 loj: 8 tus lej 3. tooj liab clad board (Tshuag PCB), txiav ib daim duab (saib cov kauj ruam tom ntej rau qhov ntev) 4. qhov muag zoo li qub loupe5. Lub roj teeb tuav (4xAA tus tuav lub roj teeb) Khoom siv: 1. Multistrand txuas cov hlau nrog rwb thaiv tsev yas, 2 xim - 1 ko taw txhua2. Instant kua nplaum 3. Cov hlau txuas thiab xaim 4. hlau txiav

Kauj Ruam 2: Ua PCB

Thaum koj muaj tag nrho cov cuab yeej thiab cov khoom siv, thawj kauj ruam yog npaj PCB txhawm rau txhawm rau txhawm rau teeb LEDs rau. Ntsuas txoj kab uas hla ntawm lub lens thiab txoj kab uas hla ntawm lub loupe. Cia A yog txoj kab uas hla ntawm lub lens thiab B txoj kab uas hla ntawm ntug. Sab hauv diamater (ID) Ntawm PCB ib puag ncig yuav tsum sib npaug rau A thiab txheej sab nrauv ntawm cov ntawv xov tooj cua PCB yuav tsum sib npaug rau B. A eagle brd cov ntaub ntawv rau peb cov ntawv xov xwm PCB tuaj yeem rub tawm los ntawm cov lus qhia no thiab siv raws li lossis hloov kho rau koj qhov tshwj xeeb tshwj xeeb peb tau siv Modela milling tshuab los txiav PCB, tab sis nrog kev siv zog me ntsis thiab ua siab ntev, koj tuaj yeem ua tau nws tus kheej nrog lub tshuab laum thiab cov cuab yeej dremel cais cov tooj liab hauv ob txoj kab sib dhos.

Kauj Ruam 3: Solder LEDs thiab Resistors

Thaum koj tau ua PCB lawm, nws yog lub sijhawm los npaj cov LEDs. Kuv muaj qee qhov SMD LEDs dawb hauv pob PLCC. Tab sis qhov loj tsis yog qhov tseem ceeb. Txhua qhov loj xws li 1206 lossis 0805 yuav ua ib yam nkaus. Txawm hais tias pob LED loj dua yog yooj yim dua los siv. Ib yam li ntawd, rau tus tiv thaiv, pob loj tau pom zoo txawm hais tias kuv siv qhov loj 0805 txij li qhov ntawd yog qhov kuv muaj thiab nws tsis yooj yim heev kom siv cov tshuaj tiv thaiv me me no. Muag cov LED thiab tus tiv thaiv ntawm cov ces kaum raws li qhia hauv daim duab. Koj yuav xav tau 8 xws li LED-resistor khub. Nyob kom ntseeg tau tias cov resistor tau muab muag rau LED Anode. Koj tsis xav tau kev sib xyaw ua ke nrog cov resistors soldered rau LED cathode.

Kauj Ruam 4: Soldering PCB

Kos tawm 8 txoj haujlwm sib npaug sib npaug ntawm PCB ib ncig thiab muab cov LED-Resistor khub raws li qhia hauv daim duab. Ua ntej sim ua kom cov tshuaj tiv thaiv kab mob, nws yog ib lub tswv yim zoo rau tin qhov chaw nrog cov laug. Qhov no yuav tso cai rau cov khoom siv sib txuas nrog qhov tsawg kawg ntawm kev kub ntxhov thiab tsis muaj cua sov ntau dhau ntawm cov khoom. Tuav tag nrho 8 LED-resistor khub Tom qab koj muab tshuaj txhuam rau txhua khub, kuaj seb LED teeb nrog kev pab los ntawm digital multimeter (hom kev ntsuas diode) yog li koj paub tseeb tias cov laug tsis puas LED.

Kauj Ruam 5: Kaw cov PCB thiab Txuas Cov Roj Teeb

Thaum tag nrho cov LEDs raug muag, Kua nplaum PCB (nrog cov LEDs tig mus deb ntawm lub loupe) mus rau lub lens sab ntawm loupe siv cov kua nplaum tam sim. Ceev faj kom ua raws PCB kom zoo. Tam sim no, txuas lub roj teeb mus rau PCB tooj liab tooj liab. Saib xyuas qhov sib txawv thaum siv lub roj teeb rau PCB. Kuv tsis tau siv lub hloov pauv kom tua cov LEDs thiab ua siab ncaj nws yog kev saib xyuas. Koj tuaj yeem tso On/Off hloov ua ntu zus los tua cov LEDs, Kuv tsuas yog tshem lub roj teeb los ntawm tus tuav lub roj teeb kom tua nws tawm. Yuav ua li cas lub teeb pom kev zoo ntawm lub qhov muag nrov nrov? Yuav ua li cas txheeb xyuas nws koj tus kheej hauv qhov swb tom ntej!

Kauj Ruam 6: Raison D'etre

Saib cov duab ntawm no rau koj tus kheej, ua tau zoo npaum li cas lub teeb pom kev ntawm lub qhov muag loupe ua haujlwm. Kuv tau lom zem heev tsim nws thiab txawm tias lom zem dua siv nws. Kuv vam tias koj ua ib yam, koj yuav tsum txiav txim siab ua ib qho rau koj tus kheej. Ua tsaug rau Nehul Malhotra rau PCB txoj haujlwm!
