1. Kudula
Chongani specifications, chitsanzo ndi kudula kukula kwa bolodi gawo lapansi malinga ndi processing mankhwala kapena kudula specifications zojambula.Utali ndi latitudo malangizo, kutalika ndi m'lifupi dimension ndi perpendicularity wa gawo lapansi bolodi ali mkati mwa kukula zomwe zafotokozedwa mu kujambula.
2. Silika chophimba ndondomeko kusindikiza
Choyamba, yang'anani ngati chophimba mauna, zotchinga zotchinga ndi makulidwe filimu kukwaniritsa zofunika.
Ndiye, yang'anani kukhulupirika kwa chiwerengerocho, ndipo palibe pinbole, mphako kapena yotsalira zomatira filimu.Yang'anani ndi bolodi yojambula yoyambirira, ndi kukula kwa chiwerengerocho kumagwirizana, ndipo m'lifupi mwake, mzere wa mzere, kukula kwa disk kapena zizindikiro zamtunduwu ndizofanana.
3. Kuyeretsa pamwamba
The mankhwala kutsukidwaPCBpamwamba padzakhala opanda oxidation ndi kuipitsa, ndipo adzakhala youma pambuyo kuyeretsa.
4. Kusindikiza kozungulira
Yang'anani kukhulupirika kwachithunzi cha dera, ndipo palibe dera lotseguka, pinhole, notch kapena dera lalifupi.Yang'anani ndi bolodi loyambirira lazithunzi, kukula kwachiwerengero kumagwirizana, kukula kwa mzere ndi mtunda wa mzere ndizofanana, ndipo cholakwikacho chili mkati mwazovomerezeka.
5. Kuwotcha
Yang'anani kukhulupirika kwachithunzi cha dera, ndipo palibe dera lotseguka, pinhole, notch kapena dera lalifupi.Yang'anani ndi bolodi loyambirira lojambulira, ndipo palibe etching (mzerewu ndi woonda kwambiri) kapena kukokera kosakwanira (mzerewu ndi wokhuthala kwambiri).
6. Kukana kuwotcherera
Choyamba, yang'anani kukhulupirika kwa zithunzi za solder resist, ndipo palibe zisindikizo zomwe zikusowa, ma pinholes, notches, inki seepage, makoma olendewera, ndi mawanga ochulukirapo a inki.Zimagwirizana ndi kukula kwa malo a mzere, ndipo cholakwikacho chili mkati mwazovomerezeka.
Kachiwiri, yang'anani kuchuluka kwa machiritso a solder kukana.The solder kukana wosanjikiza pamwamba kondakitala mkuwa adzayesedwa ndi pensulo, ndi pensulo kuuma adzakhala oposa 3H.
Chachitatu, yang'anani mphamvu yolumikizira ya solder kukana.Gwirani ndi kukoka wosanjikiza wa solder pa kalozera wamkuwa ndi tepi yomatira.Sipayenera kukhala kutsutsa kwa solder pa tepi.
7. Zizindikiro zabwino ndi zoipa
Yang'anani kuwoneka bwino kwa zilembo, ndipo palibe zosindikizira, zibowo, notch kapena inki, makoma olendewera, ndi madontho a inki ochulukirapo.Zimagwirizana ndi kukula kwa malo azithunzi za mzere, cholakwikacho chili mkati mwazovomerezeka, ndipo chilembacho chikhoza kudziwika bwino.
Tili ndi chidaliro kukupatsirani kuphatikiza kwabwino kwambirikutembenukira kiyi PCB msonkhano msonkhano, khalidwe, mtengo ndi nthawi yobweretsera mu dongosolo lanu la Small batch voliyumu ya PCB ndi Mid batch Volume PCB dongosolo la msonkhano.
Ngati mukuyang'ana wopanga msonkhano wabwino wa PCB, chonde tumizani mafayilo anu a BOM ndi mafayilo a PCBsales@pcbfuture.com.Mafayilo anu onse ndi achinsinsi kwambiri.Tikutumizirani mawu olondola okhala ndi nthawi yotsogolera mu maola 48.
