1, PCB Copy Engineering siv ntau txheej luam tawm hauv pawg thawj coj saib Circuit Court

Qhov no tuaj yeem tau txais los ntawm cov qauv ntawm qhov zoo tshaj plaws ntawm kev thaiv cov ntuag: hauv nruab nrab txheej rau lub hwj chim kab lossis hauv av, lub hwj huam sib txuas rau hauv pawg tswj hwm, ob sab ntawm cov rwb thaiv tsev kho, tuaj yeem ntws los ntawm qis thiab qis cuam tshuam tsis cuam tshuam txhua lwm yam; Lub puab txheej ua los ntawm thaj chaw loj ntawm cov cheeb tsam conductive, cov xov hlau muaj lub tshuab hluav taws xob muaj qhov loj me me ntawm qhov tsim muaj qhov tsis tshua muaj hluav taws xob tsis txaus hluav taws xob sib txuas daim ntawv luam ntawv, uas tuaj yeem tiv thaiv Circuit Court hluav taws xob thiab tau txais suab nrov.

2, PCB Copy Engineering ua tib zoo xaiv cov cuab yeej

Kev xaiv yuav tsum them sai sai rau cov laus ntawm cov Cheebtsam, thiab xaiv cov khoom cua sov ua kom sov ntawm cov cuab yeej me me daim txiag ntoo. Rau cov pa hluav taws xob muaj ntau zaus, yuav tsum tsim nyog siv los siv zaj duab xis kom txo cov hluav taws xob hauv Circuit Court. Hauv kev xaiv cov cav siv cav, kom xav txog nws qhov ntsuas lub suab nrov, nws yog qhov zoo tshaj plaws siv HTL, yog tias kev siv lub zog tag nrho, kev siv VDD ≥ 15V CMOS yog qhov tsim nyog.

3, PCB Luam Hluav Taws Xob Luam Ntawv luam tawm Circuit board board "hauv av"

Thaum kos lub xov tooj hluav taws xob ntau dhau ntawm lub rooj tsav xwm, ntxiv rau tuab li cov av luam hlau, lub rooj tsav xwm hauv Circuit Court yuav tsum tsis txhob nyob txhua qhov chaw ua cov kav hlau av, kom cov cuab yeej ze ze rau hauv av. Qhov no muaj peev xwm txo qis cov kab mob parasitic inductance, thaum lub qhov chaw loj hauv av muaj peev xwm txo qis lub suab nrov tawg. 4, hauv cov ntawv luam tawm Circuit Court nrog ib lossis ob tog ntawm daim phiaj hauv av

 Ntawd yog, nrog ib daim ntawv txhuas lossis hlau txuas rau cov ntawv luam tawm Circuit rau sab nraum qab (vuam saum npoo), lossis daim txiag luam ntawv ntes tau ob daim txhuas lossis hlau phaj. Cov phaj hluav taws xob hauv av tau raug teeb tsa kom ze rau qhov ua tiav ntawm cov ntawv luam tawm hauv Circuit Court thiab yuav tsum txuas nrog (SG) qhov zoo tshaj plaws hauv av taw tes ntawm lub teeb liab. Tus qauv no yog yooj yim thiab yooj yim ua ntau-txheej luam tawm Circuit Court daim txiag board. Yog tias koj xav ua kom zoo dua kev cuam tshuam kev tsuj hluav taws xob, luam tawm lub rooj tsav xwm tuaj yeem ntsia tau rau hauv lub thawv thaiv cov hlau thaiv kom tiav, kom nws tsis tsim khoom, tsis txhob teb rau cov suab nrov.

PCB luam ntawv cov kauj ruam

Thawj kauj ruam yog kom tau txais ib daig ntawm PCB, ua ntej hauv ntawv yuav sau tag nrho cov ntsiab ntawm cov qauv, tsis dhau, thiab qhov chaw nyob, tshwj xeeb tshaj yog cov diode, kev taw qhia ntawm lub raj triple, kev taw qhia ntawm IC qhov sib txawv. Nws yog qhov zoo dua rau digital lub koob yees duab ob daim duab los ntawm qhov chaw nyob. Tam sim no lub PCB ntau ua ntau dua li lub diode triode, qee tus tsis them sai sai rau tsis pom sab saud.

Qhov thib ob kauj ruam, rhuav tshem tag nrho cov ntawv laminated luam ntawv lub rooj tsav xwm, lub tin hauv PAD qhov thiab yuav tsum tau muab tshem tawm.PCB huv nrog cawv, thiab tom qab ntawd muab tso rau hauv lub tshuab ntsuas, lub tshuab ntsuas kom thaij tau thaum xav tau me ntsis ntau dua cov ntxaij vab tshaus, kom thiaj li tau txais cov duab ntshiab. Cov. Cov xov paj xov yuav sab saum toj thiab hauv qab nrog dej me ntsis sib tsoo, polishing rau tooj liab zaj duab xis, mus rau hauv lub scanner, pib PHOTOSHOP, khob qhov ob txheej feem rau hauv hom xim. Nco ntsoov tias PCB yuav tsum yog kab rov tav txawm tias ntsug, muab tso rau hauv lub scanner lossis duab thaij duab siv tsis tau.

Qhov thib peb kauj ruam, kho qhov sib txawv ntawm cov canvas, qhov sib piv, tooj liab zaj duab xis feem ntawm thiab tsis yog feem ntawm cov tooj liab zaj duab xis sib piv, tom qab ntawd thawj daim duab rau xim dub thiab dawb, xyuas seb kab ntawv puas meej, yog tias tsis meej, rov ua cov kauj ruam no. .Yog tseeb, yuav muaj sia nyob rau TOP dub thiab dawb TOP. Cov ntaub ntawv BMP ntawm BMP thiab BOT. BMP, yog tias pom cov teeb meem duab kuj tseem tuaj yeem kho thiab kho hauv PHOTOSHOP.

Kauj ruam plaub, ob txheej txheem BMP rau hauv PROTEL cov hom ntawv, feem ntau hauv PROTEL hloov mus rau ob txheej, xws li txheej ob txheej ntawm PAD thiab qhov chaw ntawm VIA kev sib tw, uas ob peb kauj ruam ua ntej ua tau zoo heev, yog tias muaj qhov sib txawv , tom qab ntawd rov ua cov kauj ruam 3. Yog li PCB daim txiag luam ntawv yog qhov yuav tsum tau ua siab ntev, vim tias qhov teeb meem me me yuav cuam tshuam rau qhov zoo thiab luam lub rooj tsav xwm tom qab ntais ntawv.

Thib tsib, TOP txheej ntawm BMP tuaj yeem hloov pauv mus rau PCB, ceev faj kom nkag mus rau hauv SILK txheej, txheej txheej yog daj, ces koj nyob hauv TOP txheej yog tracing, thiab kos duab ntaus ntawv raws li theem ob. Tom qab qhov kos yuav rho tawm ntawm SILK txheej. Rov qab paub dua kom kos tau txhua txheej.

Kauj Ruam 6, TOP hauv PROTEL PCB thiab BOT. PCB paged, mus rau hauv lub teeb ntsuas nrog OK.

Kauj Ruam 7, TOPLAYER nrog laser printers, BOTTOMLAYER feem luam tawm ntawm cov pob tshab zaj duab xis (1: 1 piv), muab zaj duab xis tso rau ntawm PCB, sib piv cov kev ua yuam kev, yog tias koj, koj ua tiav.

A thiab daim phaj qub uas yog tib daim npav ua tiav los, tab sis nws tsuas yog ua tiav ib nrab. Xeem, sim ntawv luam phaj phaj thev naus laus zis kev ua tau zoo tib yam li thawj lub phaj. Yog nws ua tiav. Nco tseg: yog tias nws yog tus multilayer thiab ceev faj polishing mus rau lub txheej ntawm sab hauv, tib lub sijhawm, rov qab ua cov kauj ruam, qhov thib peb mus rau daim ntawv tsib daim duab lub npe tau sib txawv, tau kawg, xav kom txiav txim siab raws li tus naj npawb ntawm txheej txheej , cov vaj huam sib luag ob chav vaj huam sib luag yooj yooj yim dua li daim txiag luam multilayer daim ntawv luam, ntau daim ntawv luam tawm daim phiaj kom nquag ua kom haum, yog li profess-sional daim board saib thiab ceev faj (suav nrog cov lus qhia sab hauv thiab lub qhov qhia tsis yooj yim kom pom qhov teeb meem).
