Hauv cov txheej txheem kev txhim kho niaj hnub, qhov zoo ntawm cov txiag hluav taws xob nrog cov khoom siv hluav taws xob ncaj qha cuam tshuam nrog cov khoom siv hluav taws xob. Txhawm rau kom muaj qhov zoo ntawm cov khoom lag luam, ntau cov tuam txhab xaiv xaiv nqa cov ntawv pov thawj kev cai ntawm PCB cov laug cam. Qhov txuas no yog qhov tseem ceeb heev rau cov khoom lag luam thiab kev tsim khoom. Yog li, dab tsi yog PCB pawg thawj coj ua ntaub ntawv pabcuam ua pov thawj suav nrog?

Kos Npe thiab Kev Pab Tswv Yim

1. Xav soj ntsuam: PCB cov tuam ntxhab uas yuav tsum muaj kev sib txuas lus hauv-tob kom nkag siab txog lawv cov haujlwm hauv Circuities, xws li cov khoom siv Circuities, cov ntaub ntawv, thiab daim ntawv qhia txog kev xaiv ntsej muag. Tsuas yog los ntawm kev nkag siab ntawm cov neeg siv khoom xav tau peb tuaj yeem muab cov kev daws teeb meem.

2. Tsim qauv rau kev tsim khoom lag luam (DFM) tshuaj xyuas: tom qab tus qauv PCB tiav, yuav tsum muaj cov kev tsim kho tau zoo, yuav tsum muaj cov teeb meem tsim qauv thiab kom tsis txhob tsim cov teeb meem kev tsim qauv.

Cov khoom siv xaiv thiab npaj

1. Substrate Cov Khoom Siv: Cov ntaub ntawv Substrate muaj xws li FR4, CEM-1, CEM-1, cov kev xaiv ntawm cov khoom siv ntawm Circuities, ib puag ncig cov yuav tsum tau, thiab muaj kev txiav txim siab txog kev txiav txim siab.

2. Cov ntaub ntawv ua cim: feem ntau siv cov ntaub ntawv luam tawm muaj xws li tooj liab ntawv ci, uas feem ntau muab faib rau hauv electrolytic tooj liab thiab colled tooj liab. Lub thickness ntawm tus tooj liab ntawv ci yog feem ntau ntawm 18 microns thiab 105 microns, thiab yog xaiv raws li cov khoom muaj peev xwm tam sim no ntawm kab.

3. Cov ntaub qhwv thiab plating: cov paths thiab conductive paths ntawm PCB feem ntau yuav tsum tau kho tus kab mob vuam, thiab lwm yam, txhawm rau txhim kho kev vuam kev ua haujlwm thiab cov pcb.

Kev tsim khoom thiab tswj kev tswj hwm

1. Kev Loj Hlob thiab Kev Tsim Kho: Qhov tsim qauv kev tsim qauv hluav taws xob yog pauv mus rau tus qauv tooj liab los ntawm kev raug cov qauv Circuit Court yog tsim tom qab kev loj hlob.

2. Etching: ib feem ntawm tus kws tooj liab cov ntawv ci tsis duav los ntawm cov photoresist tau raug muab tshem tawm los ntawm cov tshuaj etching, thiab cov khoom lag luam luam ntawv yog khaws cia.

3. Drash: tho ntau qhov chaw thiab nce qhov ntawm lub PCB raws li cov qauv tsim. Qhov chaw thiab txoj kab uas hla ntawm cov qhov yuav tsum tau ua kom meej meej heev.

4. Electroplating: electroplating yog ua nyob rau hauv lub qhov drilled lub qhov thiab ntawm cov kab npoo kom nce kev coj ua thiab corrosion tsis kam.

5.

6. Silk Screen Printing: Silk Screen Cov Ntaub Ntawv, suav nrog cov chaw sib txuas thiab cov ntawv sau ua ke, tau luam tawm ntawm PCB los pab txhawb kev sib dhos txuas ntxiv thiab txij nkawm.

Sting thiab tswj kev tswj hwm zoo

1. Kev kuaj hluav taws xob: Siv cov khoom siv kev tshaj lij los tshawb xyuas cov qauv hluav taws xob kom ntseeg tau tias txhua txoj kab sib txuas, qhib kev ncig ua si, thiab lwm yam.

2. Kev soj ntsuam ua haujlwm: Nqa cov kev ntsuas ua haujlwm raws li cov xwm txheej thov tau tseeb los txheeb xyuas seb tus PCB tuaj yeem ua tau raws li cov cai.

3. Ib puag ncig kev sim: Ntsuas pcb hauv cov huab cua zoo xws li cov cua sov siab thiab cov av noo los xyuas nws txoj kev ntseeg tau nyob hauv ib puag ncig hnyav.

4. Pom kev tshuaj xyuas: los ntawm phau ntawv lossis tsis siv neeg soj ntsuam (AOI), xws li kab tawg, qhov chaw sib txawv, thiab lwm yam.

Cov Khoom Me Me Me thiab Cov Lus Taw Qhia

1. Cov khoom lag luam me me: tsim cov lej ntawm PCBs raws li cov neeg siv khoom xav tau kev kuaj thiab pov thawj ntxiv.

2. Tsom cov lus pom zoo: Cov teeb meem tawm tswv yim pom thaum lub sijhawm sib txuas me me rau cov qauv tsim thiab pab neeg tsim nyog thiab kev txhim kho tsim nyog.

3. Kev ua kom zoo thiab kho kom haum thiab hloov kho: raws li kev sim cov lus tawm tswv yim, cov phiaj xwm tsim qauv thiab tsim kho kom ntseeg tau tias cov khoom lag luam zoo thiab muaj kev ntseeg tau.

PCB Board Cov Ntaub Ntawv Kev Pabcuam Ua Haujlwm yog qhov txheej txheem xaiv ua haujlwm npog DFM, kev kuaj cov txheej txheem, kev sim, kev pabcuam tom qab muag. Nws tsis yog tsuas yog ib qho txheej txheem tsim khoom yooj yim, tab sis kuj yog txhua qhov kev lees paub ntawm cov khoom lag luam zoo.

Los ntawm kev siv hluav taws xob ntawm cov kev pabcuam no, cov tuam txhab tuaj yeem txhim kho cov khoom lag luam thiab kev ntseeg tau, luv luv kev tshawb fawb, thiab txhim kho kev sib tw, thiab txhim kho kev sib tw ua lag luam.
