Kev tu tus kheej thiab kev daws teeb meem ntawm cov teeb meem me me hauv cov teeb pom kev zoo

Kev tu tus kheej thiab kev daws teeb meem ntawm cov teeb meem me me hauv cov teeb ci Cov teeb meem me me ntawm cov teeb ci tuaj yeem kho thiab tshem tawm ntawm koj tus kheej. Yog tias nws pom tseeb tias dej nkag los yog luv luv thiab hlawv, koj tuaj yeem hloov nws nrog cov khoom siv los ntawm koj tus kheej. Hauv qhov no, lub plhaub yog qhov tseem ceeb. Yog tias lub plhaub kim lossis tag nrho cov teeb tsis zoo, xws li teeb pom kev nyab xeeb thiab teeb pom kev zoo, yuav tsum tau hloov lub teeb ci thiab tsav tsheb, thiab koj tuaj yeem hloov koj tus kheej nrog qee cov sealant. Qhov kev tawm tswv yim yog nrhiav cov chaw tsim khoom uas ua qhov no thiab yuav cov txheej txheem sib txuam, ntsuas qhov loj thiab thaij duab, thiab tsis txhob muab lub teeb ci rau hauv nws thaum koj yuav nws, tshwj xeeb tshaj yog tsis txhob yuav nws nyias, tsis txhob xav tias nws pheej yig! Yog tias nws dheev tawm los yog tsaus ntuj, tab sis lwm yam circuits tsis zoo, uas yog hais tias, lwm yam khoom siv hluav taws xob zoo. Nyob rau hauv rooj plaub no, lub teeb nws tus kheej yog ntshai, uas yog, nws yog tawg. Qhov xwm txheej no muaj ntau dua. Peb xub tshem lub teeb thiab maj mam txheeb xyuas! Ua ib qho yooj yim LED teeb ua piv txwv, qhib lub hau ua ntej, thiab xaiv nws raws ntug qhov sib txawv nrog ib rab riam. Tom qab qhib, saib seb tus neeg tsav tsheb lub teeb siv li cas, seb nws puas yog lub rooj tsav xwm txuas nrog lub teeb vaj huam sib luag lossis cov khoom siv yog soldered rau lub teeb vaj huam sib luag. Ntawd yog, txoj kev ywj pheej IC thiab DOB, kev ywj pheej IC yog teeb meem me ntsis. Thawj qhov kev daws teeb meem: thawj zaug xyuas seb lub teeb hlaws puas nyob hauv qhov zoo. Yog tias muaj cov pob dub nyob hauv nruab nrab ntawm lub teeb hlaws, nws yog qhov pib tawg. Yog tias tsuas muaj ib lossis ob qhov phem, koj tuaj yeem kho koj tus kheej. Yog tias nws phem dhau lawm, cia li hloov nws! Lub teeb hlaws hluav taws kub hnyiab Kev daws teeb meem ob lub ntsiab lus: seb lub teeb kab txuas ntawm txoj kev teeb pom kev tsis raug, tshwj xeeb tshaj yog cov kab ntawm lub teeb lub taub hau, cov kab ntawm no yooj yim poob tawm, sim rub tawm maj mam nrog koj txhais tes kom pom tias nws tsis nyob rau hauv kev sib cuag zoo, kev saib xyuas kuj yooj yim, tus ntsia thawv ntawm lub teeb lub taub hau tuaj yeem nqa nrog cov hniav poob.

Lub ntsiab lus thib peb ntawm kev daws teeb meem: Yog tias nws yog DOB kev daws teeb meem, uas yog, ib qho ntawm cov khoom siv tag nrho ntawm lub vaj huam sib luag, xyuas seb puas muaj qhov sib txawv ntawm cov khoom siv, koj tuaj yeem qhib lub hwj chim, thiab sim nias lawv ib qho los ntawm ib qho nrog cov ntsia hlau insulated kom tshem tawm qhov yuam kev. Yog tias nws tau tsav los ntawm ib qho kev ywj pheej IC, nws yog qhov ntau dua tias cov xov hlau txuas ntawm ob sab tau tawg los yog kev sib cuag tsis zoo, thiab daim ntawv tooj liab yog warped. Koj tuaj yeem solder nws tus kheej thiab siv nws. Yog tias tsis muaj teeb meem tshwm sim saum toj no, koj tsuas tuaj yeem yuav lwm tus rau DOB. Koj tuaj yeem sim hloov tus tsav tsheb rau IC los txiav txim seb nws puas yog teeb meem tsav tsheb lossis teeb meem teeb meem. Tsis muaj tsav tsheb? Tshem lwm lub teeb thiab hloov nws! Yog koj pheej yig koj yuav pheej yig mus txog thaum kawg! Yog tias tus tsav tsheb tsis qhib, nws yog ib qho teeb meem ntawm lub teeb ci, thiab yog tias tus tsav tsheb qhib, nws yog ib qho teeb meem nrog tus tsav tsheb! Kev saib xyuas yooj yim ntawm LED teeb qhov chaw Nws yog qhov yooj yim rau kev sim nrog multimeter. Yog tias tsis muaj multimeter, koj tuaj yeem ua ntej nruab lub teeb ntawm lub teeb lub teeb, tig lub teeb, thiab siv cov tweezers lossis cov zoo li txuas rau ob qhov kawg ntawm lub teeb hlaws. (Qhov voltage ntawm lub teeb hlaws ntawm no tsuas yog 2- 3 volts tsis txaus ntshai) Yog tias lub teeb tuaj yeem tshwm sim tom qab sib txuas, tom qab ntawd rub nws tawm, solder lub teeb zoo li hlaws koj tus kheej lossis ncaj qha rau nws nrog tin hlau.

Yog tias nws tsis teeb tom qab txuas, ces qhov teeb meem tsis txwv ntawm no. Ua ntej, hloov lub teeb hlaws tsis raug nrog lub teeb hlaws thiab solder nws nrog tin hlau ua ntej txuas ntxiv mus sim lwm cov hlaws teeb. Koj tuaj yeem hla ntau lub teeb hlaws Cia peb sim hauv ntu ua ke kom paub seb qhov ntau ntawm cov hlaws teeb tsis raug mus txog thaum pom tag nrho cov hlaws tsis zoo pom thiab hloov. Kev saib xyuas yooj yim ntawm LED tsav tsheb Qhov kev puas tsuaj rau cov khoom siv hluav taws xob tsis tuaj yeem kho. Ntawm no peb tsuas tuaj yeem pom qee qhov chaw uas cov pob qij txha pob txha poob rau kev kho yooj yim. Thov nco ntsoov tias tsis yog txhua tus neeg tsav tsheb ntawm tib lub chaw tsim khoom thiab tib lub ntsiab lus thiab cov qauv tsis yog universal, thiab tib yam tsis tuaj yeem hais rau cov khoom siv hluav taws xob. Universal, tab sis nws twb tau tawg lawm, thiab nws yuav zoo rau solder ib qho chaw uas koj tuaj yeem nkag siab yog tias koj muaj cov xwm txheej.
