Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws Cov coj txuas tsuas yog me ntsis dhau los ntawm lub cev ntawm ib feem uas yuav zoo txaus kom tau txais cov khoom siv sib txuas ib ntus. Thaum ib feem me ntsis nyam mus rau ntawm lub rooj tsavxwm, txav mus rau sab nraud, ua kom sov li cas cov hmoov txhuas tau txuas ntxiv thiab lub ncoo hauv qab nws. Koj yuav tsum tau txais cov hlaws soldering ntug ntawm cov hlau lead rau lub ncoo, thiab yog tias koj muaj cov dej ntws zoo nws yuav tsum nqus nws hauv qab me ntsis ib yam nkaus. Rov qab mus thiab ua kom zoo rau sab uas tsuas yog tuav los ntawm kev cia siab thiab thov Vajtswv thiab koj yuav tsum ua tiav.

Kauj ruam 4: Chip Qhov

Cov ntu ntu lossis SMA/SMB qhov chaw, zoo li cov neeg tiv thaiv, cov khoom siv hluav taws xob, thiab cov diodes yog qhov yooj yim heev, tsuas yog ntws mus txog qhov kawg me ntsis, ua kom sov lub qhov muag muag ntawm lub rooj tsavxwm thiab thawb nws kom paub tseeb tias cov laug txuas rau ib sab. Yuav luag txhua lub sijhawm ib feem yuav ua kab ntawm cov pawm. 603 zoo li luv me ntsis tab sis yuav laug, 1206 qhov tsuas yog qhov zoo tshaj, 805 qhov loj me yog qhov zoo, txheej nrog ntug ntawm txhua lub ncoo

Qhov SMA/SMB yog qhov loj heev thiab feem ntau yog kab ntau dua 2 lossis peb qhov.

Hauv kuv daim duab thib ob Kuv muaj cov khoom siv hluav taws xob, thiab 2 1206 tus tiv thaiv nrog tus choj txuas nruab nrab ntawm 2 tus tiv thaiv vim kuv paub tias kuv yuav xav tau tso cov hlau nyob tom qab.

Kauj Ruam 5: TSOP 16 IC

Tam sim no kuv muaj cov khoom kuv xav tau rau 555 lub sijhawm teev tseg, nws yog lub sijhawm rau IC tom ntej. Nws yog 74F161 (yog kuv hais F, yog li nws qub heev) uas yog hauv TSOP16 pob. TSOP's zoo ib yam li DIP pob hauv kev teeb tsa, tsuas yog me dua thiab ua kom nyias nyias.

Qhov teeb meem nrog tso lawv rau ntawm daim ntawv yog koj kawg nrog 2 tus pin ntawm IC sib koom ib lub ncoo. Qee zaum qhov no tuaj yeem ua haujlwm zoo rau koj li ntawm ob peb tus pin, tab sis qhov no yog qhov cuam tshuam loj. Muaj ob peb txoj hauv kev los daws nws.

Ib qho yog txhawm rau txuas ib pawg ntawm cov xov me me rau cov hlau lead thiab tom qab ntawd muab lawv txuas rau cov ntaub qhwv, Kuv tau ua qhov no ob peb zaug thiab nws ua haujlwm hauv kev ua siab ntev. Ntxiv rau txij li thaum koj tso cov nti rau sab tooj liab ntawm lub rooj tsavxwm koj yuav tsum tso qee daim kab xev los tiv thaiv cov pins los ntawm luv luv ntawm cov pawm hauv qab lub nti.

Lwm qhov yog xaj kom lub rooj sib tsoo tawg uas hloov pauv qhov loj ntawm lub nti. uas tuaj yeem kim, thiab koj yuav tsum tau tos nws.

Lossis koj tuaj yeem tsuas yog ob npaug ntawm cov ntaub qhwv uas koj yuav tsum tau ua nrog, thiab qhov no yooj yim heev nrog rab riam siv hluav taws xob. Cia kuv qhia koj li cas koj li cas. Nqa koj rab riam hluav taws xob thiab tso nws li ib nrab txoj kev hla lub ncoo ntawm ib sab ntawm lub qhov, tuav nws ntawm lub kaum sab xis mus rau sab laug zoo ib yam li \, nias qis me ntsis … nws tsis siv ntau thiab nqa. Tom qab ntawd ua tib yam ntawm lwm sab ntawm qhov kev txiav koj tsuas yog tuav nws ntawm / lub kaum sab xis, thiab nws yuav tsim tawm (ntau dua lossis tsawg dua) V thais.

Kuv tsis txhob sim ua ob sab ntawm lub qhov ntawm ib zaug, vim nws ua haujlwm zoo tshaj yog tias koj mloog zoo lub teeb ntawm qhov kawg ntawm cov hniav, tab sis xav tias yuav sim. Qhov no ua haujlwm tau zoo nrog cov ntaub qhwv ncig, tab sis nws ua haujlwm tau zoo nrog cov ntaub qhwv plaub fab … Pom tseeb qhov no yuav tsis ua haujlwm yog tias koj lub qhov txhab muaj sab hauv ntawm lub qhov plated, tab sis koj tuaj yeem siv lub qhov me me los tshem qhov ntawd yog tias koj xav tau.

Kauj Ruam 6: PLCC

PLCC tuaj nyob rau txhua qhov ntau thiab tsawg, tab sis koj yuav pom tias ntau ntawm cov pob loj dua yuav haum rau ntawm lub qhov txhab, thiab feem ntau lawv tau ua rau pom ntawm ob sab ntawm lub nti uas koj tuaj yeem siv tau rau. Hauv kuv qhov xwm txheej kuv tab tom siv PLCC 4 tus pin LED's thiab lawv haum rau qhov zoo tag nrho ntawm 4 lub pawm, tsuas yog plop thiab solder.

Tom qab ntawd nws tsuas yog ob peb tus neeg tawm tsam ntxiv thiab qee qhov thaiv thiab pawg thawj coj no tau npaj mus. Kuv yuav tsis nkag mus ntau qhov nthuav dav txog thaiv, ua rau, zoo, nws txoj hlua. Kuv nyiam siv cov hlau tsis muaj rwb thaiv tsev thaum twg los xij, koj tuaj yeem txuas ib qho kawg thiab khiav nws txhua qhov chaw uas koj xav tau yam tsis tas yuav txhawj xeeb txog kev txiav thiab hle cov pawg me me.

Koj tuaj yeem tau txais 24 qhov ntsuas tooj liab hlau los ntawm CAT5 thiab lwm yam zoo sib xws ntawm cov xov tooj sib txuas uas tau xub xav tias yuav mus tab sis koj cov phab ntsa, txawm hais tias koj yuav tsum hle nws.

Rau cov khoom uas xav tau rwb thaiv tsev Kuv siv cov hlua ntawm cov hlua hlua. Nws feem ntau yog nplua mias thiab yog tias koj hle qhov ntev ntawm nws, ntswj nws nruj, ntws nws, thiab khiav ib lub hlaws ntawm cov kab laug sab hauv nws, tam sim no koj muaj lwm qhov chaw uas tsis muaj cov "hlau" xaim.

Rau qhov kev sib txuas me me ntawm TSOP IC Kuv tau siv 30 gauge wirewrap hlau, txij li nws qhov me me nws yooj yim rau cov laug kom zoo ib yam me me pins ntawm SMD ntu, thiab muaj nyob rau txhua qhov chaw uas muag cov khoom siv hluav taws xob.

Tom qab lub rooj tsav xwm tau txuas nrog txhua qhov, peb tau npaj los ntsaws nws rau hauv 5 volts thiab saib cov LED suav nyob hauv binary. Kuv vam tias koj pom qee cov ntaub ntawv muaj txiaj ntsig hauv phau ntawv qhia no thiab yog tias koj muaj kev paub dhau los, lus nug lossis lus pom thov tso tawm hauv cov lus!
