Txhawm rau txhim kho PCB sai dua, peb tsis tuaj yeem ua yam tsis muaj kev kawm thiab kos duab, yog li PCB thev naus laus zis tau yug los. Cov khoom siv hluav taws xob imitation thiab cloning yog cov txheej txheem ntawm kev luam cov kab hluav taws xob.

1.Thaum peb tau txais cov pcb uas yuav tsum tau theej, ua ntej sau cov qauv, tsis, thiab txoj hauj lwm ntawm tag nrho cov khoom ntawm daim ntawv. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov kev taw qhia ntawm lub diode, lub transistor, thiab kev taw qhia ntawm IC ntxiab. Nws yog qhov zoo tshaj los sau qhov chaw ntawm qhov tseem ceeb nrog cov duab.

2. Tshem tag nrho cov khoom thiab tshem tawm cov tin ntawm lub qhov PAD. Ntxuav PCB nrog cawv thiab muab tso rau hauv lub scanner. Thaum luam theej duab, lub scanner yuav tsum tsa cov scanning pixels me ntsis kom tau txais cov duab meej dua. Pib POHTOSHOP, cheb lub vijtsam hauv cov xim, txuag cov ntaub ntawv thiab luam tawm rau tom qab siv.

3. Maj mam xuab zeb lub TOP LAYER thiab BOTTOM LAYER nrog cov ntawv xov paj rau cov zaj duab xis tooj liab ci. Mus rau hauv lub scanner, tso PHOTOSHOP, thiab cheb hauv txhua txheej xim.

4.Txhim qhov sib piv thiab qhov ci ntawm lub canvas kom cov khoom siv tooj liab thiab cov khoom tsis muaj tooj liab zoo sib xws. Tom qab ntawd tig lub subgraph dub thiab dawb los xyuas tias cov kab no meej. Txuag daim ntawv qhia ua dub thiab dawb BMP hom ntaub ntawv TOP.BMP thiab BOT.BMP.

5.Hloov ob BMP cov ntaub ntawv rau hauv PROTEL cov ntaub ntawv feem, thiab import ob txheej rau hauv PROTEL. Yog tias txoj haujlwm ntawm ob txheej ntawm PAD thiab VIA yeej sib npaug, nws qhia tau tias cov kauj ruam dhau los tau ua tiav zoo, yog tias muaj qhov sib txawv, rov ua cov kauj ruam thib peb.

6.Hloov lub BMP ntawm TOP txheej mus rau sab saum toj.PCB, them sai sai rau kev hloov dua siab tshiab rau SILK txheej, taug kab ntawm TOP txheej, thiab tso cov cuab yeej raws li daim duab ntawm cov kauj ruam thib ob. Tshem tawm SILK txheej thaum koj ua tiav.

7.Nyob rau hauv PROTEL, TOP.PCB thiab BOT.PCB yog imported thiab ua ke rau hauv ib daim duab.

8.Siv lub tshuab luam ntawv laser los luam tawm TOP LAYER thiab BOTTOM LAYER raws li cov duab pob tshab (1: 1 piv), muab cov yeeb yaj kiab tso rau ntawm PCB, sib piv seb nws puas yog qhov tsis raug, yog tias nws raug, nws yog tiav.
