Kev xaiv hluav taws xob soldering hlau rau soldering Circuit Court boards thiab kev txawj soldering
universal circuit board yog ib lub rooj tsav xwm luam tawm uas tau them nrog cov ntaub qhwv raws li tus qauv IC qhov sib nrug (2.54mm), thiab tuaj yeem muab tso thiab txuas nrog cov khoom siv thiab xaim raws li tus kheej xav tau, feem ntau hu ua "lub qhov rooj". Piv nrog rau kev tsim PCB phaj, perforated board muaj qhov zoo hauv qab no: qhov pib qis rau kev siv, tus nqi qis, siv tau yooj yim, thiab nthuav dav. Piv txwv li, hauv tsev kawm qib siab cov tub ntxhais kawm kev sib tw tsim hluav taws xob, cov haujlwm feem ntau yuav tsum ua kom tiav hauv ob peb hnub, yog li lawv feem ntau siv cov boards perforated.
Kev xaiv ntawm pergboard
Tam sim no muaj ob lub ntsiab ntawm perforated boards tam sim no nyob rau hauv kev ua lag luam, ib tug nrog ywj siab pads, thiab lwm yam uas muaj ntau yam ntaub ntawv sib txuas ua ke. Ib lub qhov boards muab faib ua ib leeg-sab boards thiab ob-sided boards. Raws li tus kws sau ntawv qhov kev paub dhau los, ib lub qhov boards yog qhov tsim nyog rau cov digital circuits thiab ib leeg-chip microcomputer circuits, thaum ntau lub qhov boards zoo dua rau analog circuits thiab discrete circuits. Vim hais tias cov circuits digital thiab ib-chip microcomputer circuits yog cov chips, cov circuits ntau dua; thaum analog circuits thiab discrete circuits feem ntau tsis xwm yeem. Cov pins ntawm cov khoom sib cais feem ntau yuav tsum tau txuas nrog ntau cov xov hlau. Lub sijhawm no, nws yooj yim dua yog tias muaj ntau lub ncoo txuas ua ke.
Tsis tas li ntawd, cov neeg nyeem yuav tsum paub qhov txawv ntawm ob yam khoom ntawm pergboard: tooj liab phaj thiab tin phaj. Lub ncoo ntawm lub phaj tooj liab yog liab qab, uas yog golden daj. Nws yuav tsum tau muab qhwv rau hauv daim ntawv kom tiv thaiv lub ncoo los ntawm oxidizing. Ntxuav nrog dej cawv los yog so nrog cov kua nplaum. Ib txheej ntawm tin yog plated rau saum npoo ntawm lub ncoo, uas yog ib lub phaj tin, thiab lub ncoo yog silvery dawb. Cov khoom siv substrate ntawm tin phaj yog qhov nyuaj dua li cov phaj tooj liab, thiab nws tsis yooj yim rau deform.
Kev npaj ua ntej vuam
Ua ntej soldering lub perforated board, nws yog ib qhov tsim nyog los npaj txaus nyias nyob ntawm tej rau thaiv. Cov hlau nyias nyias tau muab faib ua ib leeg-strand thiab ntau-strand: ib leeg-strand nyuaj hlau tuaj yeem khoov rau hauv cov duab ruaj khov, thiab tuaj yeem siv ua jumper tom qab tev; multi-strand nyias hlau yog mos thiab ntxhov tom qab vuam.
Lub rooj tsavxwm perforated muaj cov yam ntxwv ntawm cov ntaub qhwv nruj, uas yuav tsum tau peb cov hlau taub hau kom muaj qhov tseeb dua. Nws raug nquahu kom siv lub taub hau taub hau nrog lub zog ntawm 30W. Ib yam li ntawd, cov hlau nplaum yuav tsum tsis txhob tuab heev, nws raug nquahu kom xaiv ib txoj kab uas hla ntawm 0.5 ~ 0.6mm.
Vuam txoj kev ntawm perforated phaj
Rau cov txheej txheem ntawm cov khoom ntawm lub rooj tsavxwm perforated, feem ntau cov neeg siv "ua raws li cov vines", uas yog, tsom rau cov khoom tseem ceeb xws li chips, thiab ntxig rau lwm yam khoom raws li xav tau. Txoj kev no yog npaj thaum vuam, kev txiav txim yog qhov cuam tshuam, thiab qhov ua tau zoo yog siab. Txawm li cas los xij, vim tsis muaj kev paub dhau los ntawm cov neeg pib tshiab, txoj kev no tsis haum rau kev siv. Cov neeg pib tshiab tuaj yeem ua qhov kev teeb tsa ua ntej ntawm daim ntawv, thiab tom qab ntawd siv cov cwj mem kos rau pem hauv ntej (cov khoom siv saum npoo) ntawm lub rooj tsav xwm perforated, thiab tom qab ntawd npaj cov xaim tawm los pab txhawb lawv tus kheej vuam.
Txoj kev vuam ntawm lub rooj tsav xwm perforated feem ntau yog siv cov hlau nyias uas tau hais los saum toj no los txuas cov hlau ya. Tsis muaj ntau yam txuj ci hauv kev sib txuas cov hlau ya, tab sis kab rov tav thiab ntsug yuav tsum tau ua kom ntau li ntau tau, huv si thiab meej. Tam sim no muaj ib txoj hauv kev nrov hauv Is Taws Nem hu ua tin kev sib txuas txoj kev, raws li qhia hauv daim duab 6, kev ua haujlwm zoo thiab kev ua haujlwm ruaj khov, tab sis nws yog cov khib nyiab ntawm tin. Ntshiab tin thaiv yog qhov nyuaj dua thiab cuam tshuam los ntawm ntau yam xws li tin hlau thiab cov txheej txheem vuam tus kheej. Yog tias koj rub ib lub xov tooj nyias nyias ua ntej, thiab tom qab ntawd rub thiab txuas nrog cov hlau nyias nyias, nws yooj yim dua. Txoj kev vuam ntawm lub rooj tsavxwm perforated yog hloov tau yooj yim thiab sib txawv ntawm ib tus neeg rau ib tus neeg, tsuas yog nrhiav txoj hauv kev uas haum rau koj.
Perforated board vuam txuj ci
Cov laug cam soldered los ntawm ntau tus neeg pib tshiab yog qhov tsis ruaj khov thiab ua rau luv luv lossis qhib circuits. Ntxiv rau qhov xwm txheej xws li kev teeb tsa tsis tsim nyog thiab cov neeg ua haujlwm tsis zoo, tsis muaj kev txawj ntse yog ib qho tseem ceeb ntawm cov teeb meem no. Mastering qee qhov kev txawj ntse tuaj yeem txo qhov nyuaj ntawm Circuit Court cuam tshuam rau lub cev kho vajtse, txo cov xov hlau ya, thiab ua rau lub voj voog ruaj khov. Cia peb tham txog cov kev txawj vuam ntawm lub rooj tsavxwm perforated raws li tus sau qhov kev paub dhau los.
1. Ua ntej txiav txim siab qhov kev teeb tsa ntawm cov khoom siv hluav taws xob thiab cov xaim hauv av
Cov khoom siv hluav taws xob khiav los ntawm lub voj voog txhua lub sijhawm, thiab qhov tsim nyog lub zog tsim nyog ua lub luag haujlwm tseem ceeb hauv kev ua kom yooj yim rau hauv Circuit Court. Qee qhov perfboard layouts muaj cov ntawv ci tooj liab khiav los ntawm tag nrho lub rooj tsavxwm, uas yuav tsum tau siv los ua lub zog thiab hauv av xaim; yog tias tsis muaj cov ntawv ci tooj liab zoo li no, koj kuj yuav tsum muaj kev npaj ua ntej rau kev teeb tsa ntawm lub zog thiab hauv av xaim.
2. Ua tib zoo siv cov pins ntawm cov khoom
Lub soldering ntawm lub rooj tsavxwm perforated yuav tsum muaj ntau jumpers, jumpers, thiab lwm yam. Tsis txhob maj mus txiav tawm cov pins ntxiv ntawm cov khoom. Qee lub sij hawm nws yuav ua tau zoo dua los dhia ncaj qha mus rau cov pins ntawm cov khoom nyob ib puag ncig kom txuas nrog. Tsis tas li ntawd, rau lub hom phiaj ntawm kev txuag cov ntaub ntawv, cov khoom txiav cov pins tuaj yeem sau ua cov ntaub ntawv jumper.
3. Zoo ntawm kev teeb tsa jumpers
Nws yog ib qho tseem ceeb tshwj xeeb los qhia txog cov ntsiab lus no, ntau lub jumpers tuaj yeem tsis tsuas yog ua kom yooj yim rau kev sib txuas, tab sis kuj saib zoo nkauj ntau dua.
4. Ua tib zoo siv tus pin headers
Kuv nyiam siv cov headers vim lawv muaj ntau yam siv tau yooj yim. Piv txwv li, yog tias ob lub rooj sib txuas sib txuas, koj tuaj yeem siv tus pin headers thiab cov kab zaum. Tus pin header tsis tsuas yog ua lub luag haujlwm ntawm kev sib txuas ntawm ob lub rooj tsavxwm, tab sis kuj ua lub luag haujlwm ntawm kev sib txuas hluav taws xob. Qhov no yog qiv los ntawm board txuas txoj kev ntawm lub computer.
5. Txiav tawm daim ntawv tooj liab thaum xav tau
Thaum siv lub rooj tsavxwm perforated, txhawm rau ua kom tag nrho ntawm qhov chaw, yog tias tsim nyog, rab riam tuaj yeem siv los txiav tawm ib qho ntawm cov ntawv ci tooj liab, kom ntau cov khoom tuaj yeem muab tso rau hauv qhov chaw txwv.
6. Ua kom siv tag nrho ntawm ob sab vaj huam sib luag
Ob chav vaj huam sib luag yog kim dua, txij li thaum koj xaiv nws, koj yuav tsum siv tag nrho nws. Txhua lub ncoo ntawm lub rooj tsavxwm ob tog tuaj yeem siv los ua ib lub qhov ntawm lub qhov kom yooj yim paub txog kev sib txuas hluav taws xob pem hauv ntej thiab nraub qaum.
