Cov txheej txheem kev paub tseeb ntawm PCB daim ntawv theej board yog tsuas yog luam theej duab lub rooj tsavxwm kom luam, sau cov ncauj lus kom ntxaws qhov chaw, tom qab ntawd tshem tawm cov khoom los ua ib daim nqi ntawm cov ntaub ntawv (BOM) thiab npaj cov khoom yuav khoom, lub rooj zaum khoob yog daim duab scanned. ua tiav los ntawm daim ntawv theej board software thiab rov qab mus rau pcb board drawing file, thiab tom qab ntawd cov ntaub ntawv PCB raug xa mus rau lub phaj ua lub Hoobkas los ua lub rooj tsavxwm. Tom qab lub rooj tsavxwm tau tsim, cov khoom yuav khoom yog soldered rau lub PCB board ua, thiab tom qab ntawd lub rooj tsavxwm Circuit Court raug kuaj thiab debugging.
Cov kauj ruam tshwj xeeb ntawm PCB daim board:
Thawj kauj ruam yog kom tau txais PCB. Ua ntej, sau cov qauv, qhov ntsuas, thiab cov haujlwm ntawm txhua qhov tseem ceeb ntawm daim ntawv, tshwj xeeb tshaj yog cov kev taw qhia ntawm diode, tertiary raj, thiab cov kev taw qhia ntawm IC qhov sib txawv. Nws yog qhov zoo tshaj plaws los siv lub koob yees duab digital coj ob daim duab ntawm qhov chaw ntawm qhov tseem ceeb. Tam sim no pcb Circuit Court boards tau txais ntau thiab ntau dua. Qee qhov diode transistors tsis pom txhua.
Cov kauj ruam thib ob yog tshem tag nrho cov txheej txheem ntau txheej thiab luam cov laug cam, thiab tshem tawm cov tin hauv PAD qhov. Ntxuav PCB nrog cawv thiab muab tso rau hauv lub scanner. Thaum lub scanner scans, koj yuav tsum tau tsa lub scanned pixels me ntsis kom tau ib tug clearer duab. Tom qab ntawd maj mam xuab zeb rau saum thiab hauv qab cov khaubncaws sab nraud povtseg nrog dej gauze daim ntawv kom txog rau thaum lub tooj liab zaj duab xis yog ci, muab tso rau hauv lub scanner, pib PHOTOSHOP, thiab luam theej duab ob txheej nyias nyias. Nco ntsoov tias PCB yuav tsum tau muab tso rau hauv kab rov tav thiab ntsug hauv lub scanner, txwv tsis pub cov duab scanned siv tsis tau.
Cov kauj ruam thib peb yog los kho qhov sib piv thiab qhov ci ntawm daim ntaub kom lub ntsej muag nrog cov yeeb yaj kiab tooj liab thiab qhov tsis muaj cov yeeb yaj kiab tooj liab muaj qhov sib txawv, thiab tom qab ntawd tig cov duab thib ob rau hauv xim dub thiab dawb, thiab xyuas seb cov kab puas meej. Yog tsis yog, rov ua cov kauj ruam no. Yog hais tias nws yog tseeb, txuag daim duab raws li dub thiab dawb BMP hom ntaub ntawv TOP.BMP thiab BOT.BMP. Yog tias koj pom muaj teeb meem nrog cov duab, koj tuaj yeem siv PHOTOSHOP los kho thiab kho lawv.
Kauj ruam plaub yog hloov ob BMP hom ntaub ntawv rau hauv PROTEL hom ntaub ntawv, thiab hloov ob txheej hauv PROTEL. Piv txwv li, txoj haujlwm ntawm PAD thiab VIA uas tau dhau los ntawm ob txheej txheej ua ke, qhia tias cov kauj ruam dhau los ua tau zoo. Yog tias muaj qhov sib txawv, rov ua cov kauj ruam thib peb. Yog li ntawd, PCB luam tawm yog ib txoj hauj lwm uas yuav tsum tau ua siab ntev, vim hais tias ib qho teeb meem me me yuav cuam tshuam rau qhov zoo thiab qib ntawm kev sib txuam tom qab luam tawm.
Qhov thib tsib kauj ruam yog los hloov BMP ntawm TOP txheej rau TOP.PCB, xyuam xim rau kev hloov dua siab tshiab rau SILK txheej, uas yog txheej daj, thiab tom qab ntawd koj tuaj yeem taug txoj kab ntawm TOP txheej, thiab tso cov cuab yeej raws li mus rau daim duab nyob rau hauv lub kauj ruam thib ob. Tshem tawm SILK txheej tom qab kos duab. Rov ua dua kom txog thaum tag nrho cov khaubncaws sab nraud povtseg.
Kauj ruam thib rau yog import TOP.PCB thiab BOT.PCB hauv PROTEL, thiab nws yog OK los muab lawv ua ib daim duab.
Kauj ruam 7, siv lub tshuab luam ntawv laser los luam TOP LAYER thiab BOTTOM LAYER ntawm pob tshab zaj duab xis (1: 1 piv), muab cov yeeb yaj kiab tso rau ntawm PCB, thiab sib piv seb puas muaj qhov yuam kev. Yog tias yog, koj ua tiav. .
Ib daim ntawv luam uas zoo ib yam li thawj lub rooj tsavxwm tau yug los, tab sis qhov no tsuas yog ib nrab ua tiav. Nws tseem yuav tsum tau soj ntsuam seb qhov kev ua tau zoo ntawm hluav taws xob ntawm daim ntawv theej yog tib yam li thawj lub rooj tsavxwm. Yog zoo li no ces yeej ua tiag tiag.
Lus Cim: Yog tias nws yog lub rooj tsav xwm ntau txheej, koj yuav tsum ua tib zoo polish lub puab txheej, thiab rov ua cov kauj ruam ntawm peb mus rau qib thib tsib. Tau kawg, lub npe ntawm cov duab kuj txawv. Nws nyob ntawm tus naj npawb ntawm txheej. Feem ntau, kev luam tawm ob sab yuav tsum tau yooj yim dua li cov txheej txheem ntau txheej, thiab cov txheej txheem ntau txheej yog qhov ua rau tsis zoo, yog li ntau txheej txheej board luam ntawv yuav tsum tau ceev faj tshwj xeeb thiab ceev faj (qhov twg hauv lub vias thiab non-vias muaj teeb meem).
Muab ob npaug rau-sided luam board method:
1. Tshawb xyuas cov txheej txheem sab saud thiab qis ntawm lub rooj tsav xwm Circuit Court thiab txuag ob daim duab BMP.
2. Qhib daim ntawv theej board software Quickpcb2005, nyem "Cov ntaub ntawv" "Open Base Map" qhib daim duab scanned. Siv PAGEUP kom zoom rau ntawm qhov screen, saib lub ncoo, nias PP tso lub ncoo, saib kab thiab ua raws li PT kab… ib yam li tus menyuam kos duab, kos rau hauv cov software no, nyem "Txuag" los tsim cov ntaub ntawv B2P .
3. Nyem "Cov ntaub ntawv" thiab "Open Base Image" qhib lwm txheej ntawm cov duab scanned xim;
4. Nyem "Cov ntaub ntawv" thiab "Qhib" dua los qhib B2P cov ntaub ntawv khaws tseg ua ntej. Peb pom lub rooj tsavxwm tshiab, muab tso rau saum toj ntawm daim duab no - tib lub PCB lub rooj tsavxwm, lub qhov yog nyob rau hauv tib txoj hauj lwm, tab sis cov xov hlau sib txuas sib txawv. Yog li peb nias "Options"-"Layer Settings", tua cov kab saum toj kawg nkaus thiab lo lo ntxhuav npo ntawm no, tawm hauv ntau txheej vias.
5. Lub vias nyob rau sab saum toj txheej yog nyob rau hauv tib txoj hauj lwm raws li lub vias nyob rau hauv qab daim duab. Tam sim no peb tuaj yeem taug qab cov kab hauv qab txheej zoo li peb tau ua thaum yau. Nyem "Txuag" dua-cov ntaub ntawv B2P tam sim no muaj ob txheej ntaub ntawv nyob rau sab saum toj thiab hauv qab.
6. Nyem "Cov ntaub ntawv" thiab "Export li PCB ntaub ntawv", thiab koj yuav tau txais ib tug PCB ntaub ntawv nrog ob txheej ntawm cov ntaub ntawv. Koj tuaj yeem hloov lub rooj tsavxwm lossis tso tawm daim duab schematic lossis xa ncaj qha mus rau PCB phaj Hoobkas rau kev tsim khoom
Multilayer board luam txoj kev:
Qhov tseeb, plaub-txheej board luam ntawv board yog luam ob lub rooj tsavxwm ob tog rov ua dua, thiab txheej thib rau yog rov luam peb ob sab boards… Qhov laj thawj yog vim li cas lub rooj tsavxwm ntau txheej yog daunting vim peb tsis tuaj yeem pom cov cov kab hluav taws xob sab hauv. Yuav ua li cas peb pom lub puab txheej ntawm precision multilayer board? - Stratification.
Muaj ntau txoj hauv kev ntawm txheej txheej, xws li potion corrosion, cuab yeej stripping, thiab lwm yam, tab sis nws yog ib qho yooj yim los cais cov khaubncaws sab nraud povtseg thiab poob cov ntaub ntawv. Kev paub qhia peb tias sanding yog qhov tseeb tshaj plaws.
Thaum peb ua tiav cov txheej txheem saum toj thiab hauv qab ntawm PCB, peb feem ntau siv cov ntawv xuab zeb los txhuam cov txheej saum npoo kom pom cov txheej sab hauv; Cov ntawv xuab zeb yog cov ntawv xuab zeb zoo tib yam muag hauv cov khw muag khoom kho vajtse, feem ntau yog PCB tiaj tus, thiab tom qab ntawd tuav cov ntawv xuab zeb thiab txhuam tusyees ntawm PCB (Yog tias lub rooj tsavxwm me me, koj tuaj yeem tso cov ntawv xuab zeb tiaj tus, nias lub PCB nrog ib tus ntiv tes thiab rub rau ntawm daim ntawv xuab zeb. ). Lub ntsiab lus tseem ceeb yog ua kom nws tiaj tus kom nws tuaj yeem ua av sib npaug.
Cov tshuaj pleev ib ce thiab cov roj ntsuab feem ntau raug muab tshem tawm, thiab cov xov tooj thiab cov tawv nqaij tooj liab yuav tsum tau so ob peb zaug. Feem ntau hais lus, lub rooj tsavxwm Bluetooth tuaj yeem so hauv ob peb feeb, thiab lub cim xeeb yuav siv li kaum feeb; tau kawg, yog tias koj muaj zog ntau dua, nws yuav siv sij hawm tsawg dua; yog tias koj muaj zog tsawg, nws yuav siv sij hawm ntau dua.
Sib tsoo board tam sim no yog cov kev daws teeb meem tshaj plaws uas siv rau txheej txheej, thiab nws kuj yog qhov kev lag luam tshaj plaws. Peb tuaj yeem nrhiav PCB pov tseg thiab sim nws. Qhov tseeb, kev sib tsoo lub rooj tsavxwm tsis yog technically nyuaj. Nws tsuas yog dhuav me ntsis xwb. Nws yuav siv zog me ntsis thiab tsis tas yuav txhawj xeeb txog kev sib tsoo lub rooj tsavxwm rau cov ntiv tes.
Kev tshuaj xyuas cov nyhuv ntawm PCB
Thaum lub sij hawm txheej txheem PCB layout, tom qab qhov system layout tiav lawm, daim duab PCB yuav tsum tau muab tshuaj xyuas kom pom seb qhov system layout puas tsim nyog thiab seb qhov kev pom zoo tuaj yeem ua tiav. Feem ntau nws tuaj yeem tshawb xyuas los ntawm cov hauv qab no:
1. Txawm hais tias qhov system layout tau lees tias tsim nyog los yog pom kev xaim, seb cov xaim puas tuaj yeem ua tau zoo, thiab seb qhov kev ntseeg ntawm kev ua haujlwm hauv Circuit Court puas tuaj yeem lav tau. Hauv kev teeb tsa, nws yuav tsum muaj kev nkag siab tag nrho thiab kev npaj ntawm cov kev taw qhia ntawm lub teeb liab thiab lub zog thiab hauv av xaim network.
