1. Txiav
Xyuas cov specification, qauv thiab txiav loj ntawm lub substrate board raws li cov khoom ua los yog txiav specification drawings.Lub longitude thiab latitude kev taw qhia, ntev thiab dav dimension thiab perpendicularity ntawm lub substrate board yog nyob rau hauv lub Scope teev nyob rau hauv daim duab.
2. Silk screen txheej txheem luam ntawv
Ua ntej, xyuas seb qhov screen mesh, lub vijtsam nro thiab zaj duab xis thickness ua tau raws li qhov yuav tsum tau ua.
Tom qab ntawd, xyuas qhov tseeb ntawm daim duab, thiab tsis muaj pinhole, notch lossis residual nplaum zaj duab xis.Tshawb xyuas nrog cov duab thaij duab thawj zaug, thiab daim duab qhia qhov loj me zoo ib yam, thiab kab dav, kab sib nrug, txuas disk loj lossis cim cim zoo ib yam.
3. Nto tu
Cov tshuaj ntxuavPCBnto yuav tsum tsis muaj oxidation thiab muaj kuab paug, thiab yuav tsum qhuav tom qab ntxuav.
4. Circuit Court luam ntawv
Txheeb xyuas qhov tseeb ntawm daim duab kos, thiab tsis muaj qhov qhib Circuit Court, pinhole, notch lossis luv luv Circuit Court.Tshawb xyuas nrog cov duab thaij duab thawj zaug, daim duab qhia qhov loj me zoo ib yam, txoj kab dav thiab kab nrug zoo ib yam, thiab qhov yuam kev yog nyob rau hauv qhov kev tso cai.
5. Etching
Txheeb xyuas qhov tseeb ntawm daim duab kos, thiab tsis muaj qhov qhib Circuit Court, pinhole, notch lossis luv luv Circuit Court.Tshawb xyuas nrog cov duab thaij duab thawj zaug, thiab tsis muaj etching (txoj kab yog nyias dhau) lossis tsis txaus etching (txoj kab yog tuab dhau).
6. Tsis kam vuam
Ua ntej ntawm tag nrho cov, xyuas qhov tseeb ntawm solder resist graphics, thiab tsis muaj ploj lawm prints, pinholes, notches, number case seepage, dai phab ntsa, thiab ntau npaum li cas number case.Nws yog raws li qhov loj ntawm qhov chaw ntawm kab daim duab, thiab qhov yuam kev yog nyob rau hauv qhov kev tso cai.
Thib ob, xyuas qhov kev kho kom zoo ntawm solder resist.Lub solder tiv thaiv txheej ntawm tus neeg xyuas pib tooj liab yuav tsum tau sim nrog xaum, thiab xaum tawv yuav tsum ntau tshaj 3H.
Thib peb, xyuas qhov kev sib txuas ntawm lub zog solder.Lo thiab rub cov txheej txheem ntawm cov txheej txheem tooj liab nrog cov nplaum nplaum.Yuav tsum tsis muaj tev tawv tawv tiv thaiv ntawm daim kab xev.
7. Cov cim zoo thiab tsis zoo
Tshawb xyuas cov duab zoo ntawm cov cim cim, thiab tsis muaj cov ntawv luam tawm ploj lawm, pinholes, notches lossis inking, dai phab ntsa, thiab ntau tus number case dots.Nws ua raws li qhov loj me ntawm cov kab kos duab, qhov yuam kev yog nyob rau hauv qhov kev tso cai, thiab cov cim cim tuaj yeem raug lees paub.
