Cov txheej txheem txheeb xyuas kev ua tiav ntawm PCB daim npav yuav tsum tau theej, xa cov ntaub ntawv qhia txog cov ntaub ntawv sau npe, thiab tom qab ntawd cov ntaub ntawv kaw lus (BOM) Tom qab lub rooj tsavxwm tau tsim, cov khoom siv uas yuav khoom siv yog solded rau ua PCB board, thiab tom qab ntawd Circuit Court Board yog sim thiab debugging.

Cov kauj ruam tshwj xeeb ntawm PCB Copy Board:

Thawj kauj ruam yog kom tau txais ib tus PCB. Ua ntej, sau cov qauv, cov qauv, thiab cov haujlwm ntawm txhua qhov tseem ceeb ntawm daim ntawv, tshwj xeeb yog cov kev taw qhia ntawm lub raj, thiab cov kev taw qhia ntawm IC sib txawv. Nws yog qhov zoo tshaj plaws los siv lub koob yees duab digital coj ob daim duab ntawm qhov chaw ntawm tseem ceeb. Tam sim no PCB Circuit Coadcuit Cours tau txais ntau dua thiab ntau dua. Qee qhov ntawm cov diode tiodors tsis pom txhua.

Qhov thib ob kauj ruam yog kom tshem tawm txhua lub tsev laus thiab luam cov laug cam, thiab tshem tawm cov tin hauv lub hau. Ntxuav PCB nrog cawv thiab muab tso rau hauv scanner. Thaum lub scanner scans, koj yuav tsum tsa cov scanwed pixels me ntsis kom tau txais cov duab ntshiab. Tom qab ntawd maj mam xuab zeb sab saum toj thiab hauv qab nrog daim duab gauze dej kom txog thaum lub scerker, pib photoshop, thiab luam theej duab ob txheej sib cais hauv cov xim. Nco ntsoov tias PCB yuav tsum muab cov kab rov tav thiab vertically hauv scanner, txwv tsis pub cov duab scanned tsis tuaj yeem siv.

Kauj ruam thib peb yog los kho qhov sib txawv thiab lub ci ci ntawm cov duab liab thiab tom qab ntawd tig tus duab thib ob rau hauv cov xim dub thiab dawb, thiab tshuaj xyuas seb cov kab puas meej. Yog tias tsis yog, rov ua cov kauj ruam no. Yog tias nws yog qhov tseeb, txuag daim duab uas yog xim dub thiab dawb BMP hom ntaub ntawv top.bmp thiab bot.bmp. Yog tias koj pom muaj teeb meem nrog cov duab, koj kuj tseem tuaj yeem siv Photoshop los kho thiab kho lawv.

Kauj ruam thib plaub yog hloov mus rau ob hom ntawv BMP rau hauv cov ntaub ntawv hom yeeb yam, thiab hloov ob txheej hauv protel. Piv txwv li, txoj haujlwm ntawm ncoo thiab ntawm cov uas tau dhau los ntawm ob txheej sib txuam, qhia tias cov kauj ruam dhau los ua tau zoo. Yog tias muaj kev sib txawv, rov hais dua peb kauj ruam thib peb. Yog li ntawd, PCB luam yog txoj haujlwm uas xav tau kev ua siab ntev, vim tias muaj teeb meem me me yuav cuam tshuam qhov kev sib txuam zoo thiab kev txheeb xyuas me me tom qab kev luam tawm.

Lub thib tsib kauj ruam yog hloov kho lub BMP ntawm cov txheej saum toj kawg nkaus rau sab saum toj txheej, thiab tom qab ntawd koj tuaj yeem tso cov kab daj, thiab tom qab ntawd koj tuaj yeem tso cov txheej txheem daj, thiab tom qab ntawd koj tuaj yeem tso cov khoom daj tuaj yeem tso rau ntawm daim duab raws li cov duab thib ob. Rho tawm cov kab ntawv silk tom qab kos duab. Ua kom rov ua dua kom txog thaum txhua txheej yog kos.

Lub kauj ruam thib rau yog ua ntshuam top.pcb thiab bot.pcb hauv protel, thiab nws tsis ua li cas los sib xyaw ua ke rau hauv ib daim duab.

Lub xya kauj ruam, siv lub tshuab luam ntawv laser kom luam cov zaj yeeb yaj kiab saum toj kawg nkaus (1: Muab zaj duab xis ntawm PCB, thiab muab piv rau seb puas muaj qhov ua yuam kev. Yog tias nws yog lawm, koj ua tiav. Cov.

Daim ntawv luam theej tswv yim uas yog tib yam li thawj lub rooj tsavxwm yug, tab sis qhov no tsuas yog ib nrab ua. Nws tseem tsim nyog yuav tsum tau sim seb cov khoom siv hluav taws xob ntawm phau ntawv Copy yog tib yam li thawj lub rooj tsavxwm. Yog tias nws yog tib yam, nws yog tiag tiag ua.

NCO TSEG: Yog tias nws yog multi-pawg pawg, koj yuav tsum ua tib zoo polish Cov txheej sab hauv, thiab rov ua cov kauj ruam luam ntawm peb mus rau qib tsib. Ntawm chav kawm, lub npe ntawm cov duab kuj txawv. Nws nyob ntawm tus naj npawb ntawm cov khaubncaws sab nraud povtseg. Feem ntau, muab ib daim ntawv xa tawm ob npaug rau ntau qhov yooj yim dua li cov pawg thawj coj saib tsis muaj peev xwm ua kom zoo tshaj plaws, yog li ntau txheej txheem viassignment, yog li ntau txoj kev vias sab hauv thiab tsis yog feem ntau yog qhov teeb meem).

Muab ob sab ib sab ntawm cov qauv coj ua:
1. Kuaj cov txheej thiab qis dua ntawm cov txheej txheem Circuit Court thiab txuag tau ob daim duab BMP.

2. Qhib daim ntawv luam theej software QuickPCB2005, Nyem "File" "Qhib daim duab qhia" kom qhib daim duab scanned. Siv nplooj ntoos rau sab hauv lub vijtsam, nias PP muab cov kab kos duab, kos nws hauv cov software, nyem "kom tsim cov ntaub ntawv B2P.

3. Nyem "File" thiab "Qhib puag duab" kom qhib lwm txheej ntawm scanned xim duab;

4. Nyem "File" thiab "Qhib" dua los qhib B2P cov ntaub ntawv cawm ntxov. Peb pom cov board tau tshiab, pla tau tso rau saum cov duab no - tib pawg thawj pcb, lub qhov nyob rau tib txoj haujlwm, tab sis cov hlua sib txuas sib txawv. Yog li peb nias "Xaiv" - "txheej teeb tsa", tua cov kab qib sab saum toj thiab cov kab ntawv lo lus ntawm no.

5. Lub vias ntawm txheej saum toj yog nyob rau hauv tib txoj hauj lwm raws li txoj kev vias rau hauv qab daim duab. Tam sim no peb tuaj yeem taug txoj kab nyob rau hauv qab txheej thaum peb tau ua thaum yau. Nyem "Txuag" dua-B2P cov ntaub ntawv tam sim no muaj ob txheej ntawm cov ntaub ntawv ntawm sab saum toj thiab hauv qab.

6. Nyem "File" thiab "export raws li PCB file", thiab koj tuaj yeem tau txais cov ntawv PCB nrog ob txheej ntawm cov ntaub ntawv. Koj tuaj yeem hloov lub rooj tsavxwm lossis tso cov duab schematic lossis xa nws ncaj qha rau lub PCB phaj Hoobkas rau ntau lawm

Multilayer Board Luam Ntawv:

Qhov tseeb, plaub-Txheej Board Copyment Board yog los luam ob lub rooj zaum thib rau ntau dua, thiab cov laj thawj thib yog kom rov ua kom zoo dua yog tias peb tsis tuaj yeem pom cov hluav taws xob sab hauv. Yuav ua li cas peb pom cov khaubncaws sab nraud povtseg ntawm tus qauv multiliser board? -Txoj kev.

Muaj ntau txoj hauv kev ntawm txheej, xws li potion corrosion, cuab yeej stripping, thiab lwm yam, tab sis nws yooj yim cais cov khaubncaws sab nraud thiab cov ntaub ntawv poob. Kev paub qhia peb tias sanding yog qhov tseeb tshaj plaws.

Thaum peb ua tiav luam tawm sab saum toj thiab hauv qab ntawm tus PCB, peb feem ntau siv cov xuab zeb rau polish cov txheej saum npoo av kom pom cov txheej sab hauv; Sandpaper yog qhov qub xuab zeb muag hauv cov khw muag khoom muaj zog, feem ntau tuav cov ntaub ntawv ncaj qha, koj tuaj yeem tso cov pob zeb ncaj qha, nias lub PCB nrog ib ntiv tes thiab tshiav ntawm cov xuab zeb). Lub ntsiab lus tseem ceeb yog ua kom nws tiaj tus uas nws tuaj yeem ua rau nruab nrab.

Cov ntaub ntawv lo lo ntxhuav thiab cov roj ntsuab feem ntau yog cov ntaub qhwv tawm, thiab cov hlau tooj liab tooj liab yuav tsum tau so ob peb zaug. Feem ntau hais lus, lub Bluetooth Board tuaj yeem so tau so hauv ob peb feeb, thiab lub cim xeeb lo yuav siv li kaum feeb; Tau kawg, yog tias koj muaj lub zog ntau dua, nws yuav siv sijhawm tsawg dua; Yog tias koj muaj lub zog tsawg dua, nws yuav siv sijhawm ntau.

Kev sib tsoo board tam sim no txoj kev daws teeb meem feem ntau siv rau txheej, thiab nws tseem yog kev lag luam tshaj plaws. Peb tuaj yeem nrhiav tus PCB discarded thiab sim nws. Qhov tseeb, kev sib tsoo lub rooj tsavxwm tsis yog qhov nyuaj. Nws tsuas yog me ntsis boring. Nws siv zog me ntsis thiab tsis tas yuav txhawj xeeb txog kev sib tsoo pawg thawj coj mus rau cov ntiv tes.

PCB kos cov nyhuv tshuaj xyuas

Thaum Pcb txheej txheem txheej txheem, tom qab lub kaw lus ua tiav, PCB daim duab yuav tsum tau tshuaj xyuas seb qhov system tsim nyog yog qhov ua tiav. Nws feem ntau tuaj yeem raug tshuaj xyuas los ntawm cov hauv qab no:
1. Txawm hais tias lub kaw lus hluav taws xob tau lees paub lossis kev sib luag, puas yog cov hlau hluav taws xob muaj peev xwm ntseeg tau tias ntawm kev ua haujlwm Circuitity tuaj yeem tuaj yeem lav. Hauv kev teeb tsa, nws yog ib qho tsim nyog los muaj kev nkag siab tag nrho thiab kev npaj ntawm kev taw qhia ntawm lub teeb liab thiab lub network thiab hauv av hlau.

2. Puas yog qhov loj ntawm cov ntawv luam tawm yog xwm yeem nrog qhov loj me ntawm kev ua tiav kos, txawm tias nws tuaj yeem ua tau raws li cov cai ntawm pcb kev tsim qauv, thiab seb puas muaj tus cwj pwm kos. Qhov no yuav tsum muaj kev saib xyuas tshwj xeeb. Cov txheej txheem Circuit Coutout thiab cov xaim hluav taws xob ntawm ntau tus thawj coj PCB yog tsim qauv zoo nkauj heev thiab tsim qauv ntawm kev tsim qauv yog tsis saib xyuas, ua rau muaj kev sib tw nrog lwm cov kev sib tw.

3. Txawm hais tias cov khoom siv tsis sib haum xeeb nyob rau hauv ob qho chaw thiab peb-seem. Them sai sai rau qhov tseeb me me ntawm cov cuab yeej, tshwj xeeb tshaj yog qhov siab ntawm lub cuab yeej. Thaum vuam Cheebtsam tsis muaj kev teeb tsa, qhov siab yuav tsum tsis tshaj 3mm.
