Txawm hais tias koj tab tom pib tawm ntawm koj cov khoom siv hluav taws xob thiab tsuas yog xav tau txheeb xyuas tsib txoj hlua tiv thaiv kab mob, lossis zoo li kuv tus kheej, koj tau sau tag nrho pawg ntawm cov khoom siv ntau xyoo thiab tsis paub tseeb tias lawv yog dab tsi lossis lawv puas yog tseem ua haujlwm, qhov ntsuas ntsuas no yuav pab koj tawm. Nws hloov pauv tau yooj yim thiab txawm hais tias nws tsuas yog hais tias transistor tester nws tuaj yeem ua tau ntau yam ntxiv.

Hauv Cov Lus Qhia no kuv qhia yuav ua li cas tsim lub ntsuas los ntawm cov khoom siv. Kuv qhia cov txheej txheem tsim tiav thiab taw qhia txhua yam teeb meem. Cov vis dis aus qhia txog kev tsim thiab cov hauv qab no piav qhia cov txheej txheem.

Cov khoom siv muaj nyob ntawm qhov txuas no:

DIY M12864 Graphics Version Transistor Tester Kit LCR ESR PWM

Tsis muaj cov lus qhia nrog cov khoom siv tab sis lub rooj tsav xwm hauv Circuit Court tau hais meej meej nrog cov khoom muaj txiaj ntsig. Tsuas yog ua tib zoo xaiv cov khoom kom raug thiab tso rau lawv raws li qhia.

Kauj Ruam 1: Solder cov Resistors

Thaum tsim cov khoom siv no nws yog lub tswv yim zoo los pib nrog cov khoom sib txuas qis tshaj ua ntej thiab qhov ntawd yuav yog cov tiv thaiv. Qhov tseem ceeb ntawm tus tiv thaiv nyob hauv tsib txoj kab xim xim thiab qhov ntawd tsis yog ib txwm ncaj ncaj los txiav txim siab. Txheeb xyuas txhua tus nqi nrog lub multimeter kom ntseeg tau.

Tom qab soldering saib xyuas thaum txiav cov khoom ua rau yaug nrog lub rooj tsavxwm. Tsis txhob cia cov coj tsuas yog ya ncig txhua qhov chaw vim tias lawv yuav pom lawv txoj hauv kev qhov chaw uas lawv tsis xav tau!

Kauj Ruam 2: Solder Capacitors

Cov capacitors yog rau feem ntau pom meej meej. Muaj ib qho 1 nanofarad capacitor cim ua 1 n J, qhov no tau hais meej meej ntawm daim phiaj. Muaj ob lub electrolytic capacitors uas yog polarized yog li ua tib zoo mloog thaum haum lawv. Qhov tsis zoo yog cim rau ntawm lub tshuab hluav taws xob thiab ntawm lub rooj tsav xwm hauv Circuit Court sab tsis zoo tau qhia los ntawm kab. Qhov ua tau zoo ntawm lub capacitor ntev dua. Muaj ib qho ntxiv capacitor suav nrog tab sis qhov no tsis yog ib feem ntawm kev tsim qhov no yog rau ntsuas ntsuas tus ntsuas. Nws tau ncig hauv cov xim daj hauv daim duab.

Thaum haum ob lub me me 22 Picofarad capacitors tsis thawb lawv lossis yuam lawv nqes mus rau ntawm lub rooj tsavxwm nyob deb. Yog tias koj sim thiab yuam lawv txhua txoj kev nqes mus rau lub rooj tsav xwm hauv Circuit lawv yuav tawg.

Kauj Ruam 3: Solder Transistors

Tom ntej no haum rau transistors. Kuv muab ib qho ntawm cov tooj dag txuas rau lub LCD ntawm lub rooj tsavxwm raws li qhov taw qhia rau qhov siab. Koj tsis xav kom cov transistors tawm mus deb dhau thiab kov lub LCD. Nco ntsoov xyuas tus lej transistor tus lej tiv thaiv PCB npav.

Kauj Ruam 4: Muab Cov Khoom Siv Tshuav

Tam sim no haum cov khoom seem. Cov clip rau lub roj teeb, hloov pauv, lub qhov (socket) rau lub khoos phis tawj, siv lead ua, lub qhov (socket) rau lub LCD thiab xoom tso lub zog "ZIF" qhov (socket). Ob ntawm cov no tau muab nrog kuv cov khoom siv rau qee qhov laj thawj, xaiv qhov koj nyiam xim!

Qhov txuas rau sab saum toj rau LCD tau cim tias yog 5 txog 12. Qhov sib xws nrog lub taub hau uas koj muab tso rau ntawm lub LCD uas pib ntawm tus pin 5. Ua tib zoo saib xyuas me ntsis nrog cov siv lead ua, ob txhais ceg dhau los ntawm cov iav insulators yog li tsis txhob ntxhov siab ob txhais ceg. Lub qhov (socket) rau tus khoos phis tawj muaj qhov taw qhia rau tus pin 1 me ntsis hniav nyob rau sab saum toj. Qhov ntawd qhia tau tias lub ces kaum sab saum toj yog tus pin 1. Thaum kawg LED tau cim dua ntawm lub rooj tsav xwm. Nws muaj lub tiaj tiaj ntawm ib sab los qhia qhov ua tsis zoo thiab zoo ib yam rau lub capacitors qhov zoo ntawm LED yog ntev dua.

Kauj Ruam 5: Txheeb xyuas qhov Voltage

Ua ntej teeb tsa lub khoos phis tawj, txuas lub roj teeb thiab tshawb xyuas lub zog sib txuas ntawm lub nti. Txhawm rau ua qhov ntawd peb suav nrog tus pin 7 uas yuav tsum yog qhov zoo thiab tus pin 22 yuav tsum tsis zoo thiab lawv nyob nraum ib leeg nyob ib leeg hauv IC qhov (socket). Koj yuav tsum pom +5 volts ntawm tus pin 7 thaum koj nias qhov hloov pauv. Peb tuaj yeem tso tus txheej txheem tam sim no, raws li muab ob txhais ceg tej zaum yuav ua me ntsis dhau los ua kom haum rau hauv lub qhov (socket). Maj mam, ntawm qhov chaw tiv thaiv zoo li qub, khoov tus pin kom lawv nyob ncaj qha.

Ntawm tus khoos phis tawj, tus pin ib tus tau qhia los ntawm kev nkag mus rau ib qho kawg. Txheeb xyuas tias txhua tus pins tau rov qab mus tsev rau hauv lawv lub qhov rooj.

Haum rau lub vaj huam sib luag LCD thiab roj teeb los ntsuas tias nws ua haujlwm.

Kauj ruam 6: Calibration

Txhawm rau ntsuas ntsuas chav tsev peb yuav tsum tau tsim cov kab txuas sib txuas los koom nrog 1 2 & 3 lub dav hlau. Ntawm ZIF lub qhov (socket), thawj 3 txoj haujlwm yog "1" txoj haujlwm nruab nrab yog "2" nyob ib sab ntawm kab uas koj tuaj yeem pom hauv ZIF lub qhov (socket) thiab tom qab ntawd peb kawg yog "3". Nrog qhov txuas hauv qhov chaw ua raws cov lus qhia kom txog rau thaum nws hais tias "cais cais" tom qab tshem qhov txuas. Tom qab ntawv nws yuav qhia koj kom muab lub ntsuas hluav taws xob tso rau hauv thiab qhov ntsuas yuav ua tiav.

Kauj Ruam 7: Haum Case

Qhov kev sib tw tom ntej yuav haum tus qauv rau hauv rooj plaub. Thaum sim ua kom haum tus qauv rau hauv rooj plaub peb ntsib teeb meem. Thaum peb muab cov khoom nce vim yog qhov siab ntawm lub vaj huam sib luag LCD ZIF lub qhov rooj tau so thiab koj tsis tuaj yeem tau txais cov txiv ntoo mus rau qhov hloov pauv. Kuv qhov kev daws teeb meem yog txhawm rau txiav tawm qhov screen kom nws hla mus.

Kuv kuj tau qhib qhov seem ntawm qhov rau ZIF qhov ntsaws qhov rooj. Qhov no ua rau lub latch kaw tag nrho.

Kuv ua tsaug rau Banggood rau kev muab cov khoom siv no los tshuaj xyuas thiab kuv vam tias koj muaj kev lom zem ntau npaum li nws tau ua.

Kauj Ruam 8: Sijhawm Xeem

Nrog chav ua tiav peb tam sim no tuaj yeem txheeb xyuas los ntawm peb pawg ntawm cov khoom siv txhawm rau txheeb xyuas lawv thiab txheeb xyuas tias lawv ua haujlwm tau zoo.
