Mavuto wamba ndi zotsutsana mu FPC ndi PCB ntchito yopanga

Ndi kusintha kwa kuwotcherera pamwamba kukhala mtundu wopanda-kutsogolera, PCB dera bolodi ayenera kunyamula kopitilira muyeso-mkulu kuwotcherera kutentha, ndi kufunika matenthedwe kukana mantha a kunja padziko solder kukana wosanjikiza ndi apamwamba ndi apamwamba. Kufunika kwa chithandizo chamatenda osachiritsika, kuyang’ana mphamvu ya solder kukana wosanjikiza (inki, masking film) ndikumata ndi mkuwa wam’munsi ndikokwera kwambiri. Timafunikira ukadaulo wabwinopo wothandizila kuti tiwonetsetse. Mwa kukonza ukadaulo wathu, titha kusintha zokolola za katundu ndikukwaniritsa phindu. Mankhwala opangira chithandizo chamtundu wapamwamba mosakayikira atha kutithandiza pamtengo wotsika.

Nkhaniyi imayambitsa mafunso ndi ma Countermeasure omwe nthawi zambiri amakumana nawo pakupanga kwa PCB ndi FPB bolodi lofewa: choyamba, gawo la mzere limapereka kukokoloka kwa mbali ndi mawonekedwe a concave mukamakumba mzere pambuyo pa kanema wouma kapena chithandizo chamakanema, zomwe zimayambitsa kusowa kwa mzere m’lifupi kapena mzere m’goli. Chifukwa chake ndichosankha kosayenera kwamafilimu owuma ndi onyowa okha, magawo osayenera ndi kuwonongeka kwa makina owonekera. Kukula, kutentha kwa gawo lazomata, kusakhazikika kwazinthu zina, mayendedwe osayenera ndi kuchuluka kwa mankhwala amadzimadzi, liwiro loyendetsa mosayenera ndi mndandanda wina zingayambitse mafunso. Komabe, nthawi zambiri timapeza kuti palibe chachilendo poyang’ana magawo omwe ali pamwambapa ndi zida zina zogwirizana nazo, komabe pali mafunso ena okhudzana ndi dzimbiri komanso kuwonongeka kwa concave kwa board board popanga bolodi. Kodi chifukwa chake ndichani?

2, Pochita mawonekedwe a electroplating a PCB ndi chithandizo chapamwamba pa malo a PCB ndi FPC, monga golide, golide wamagetsi, malata amagetsi, malata am’mankhwala ndi zina zamankhwala, nthawi zambiri timapeza kuti matabwa omwe amapangidwa amawonetsa mawonekedwe olowera mkati ya kanema wouma ndi wouma kapena solder wokana kusanjikiza, kapena matabwa ambiri kapena ena am’mabwalo am’deralo, Ziribe kanthu mtundu wanji wa vutoli, zidzabweretsa kuperewera kapena zolakwika zosafunikira, zovuta zosafunikira kukonzanso pambuyo pake, ngakhale kutha kumapeto , zomwe zimapweteka kwambiri! Chifukwa chake ndichakuti nthawi zambiri timaganizira zamafilimu owuma ndi onyowa, ndipo magwiridwe antchito a deta ndi okayikira; Pali mafunso okhudzana ndi kuthana ndi solder, monga inki ya bolodi yolimba, masking film for soft board, kapena mafunso posindikiza, kukanikiza, kuchiritsa ndi magawo ena. Zowonadi, malo aliwonsewa amatha kuyambitsa kukayika. Kenako tasokonezedwanso kuti palibe chikaiko kapena chikaiko pagawo ili pamwambapa, komabe ziwonetserabe mawonekedwe olowerera. Kupatula apo, ndi chifukwa chanji chosazindikira?

3, matabwa a PCB adzayesedwa ndi malata asanatumizidwe. Zachidziwikire, makasitomala amagwiritsa ntchito malata otsekemera. Palibe chikaiko kuti inki imatha kusendedwa kwambiri kapena kuti mphamvu yosenda ya kanema wophimba wa mbale yofewa ndikusowa kapena kufanana, Makasitomala, makamaka omwe amachita bwino SMT, sangakhale ndi mafunso ngati awa. Solder ikakana kusanjikiza ikawonetsa kuwunika kosalala panthawi yowotcherera, zimapangitsa kuti zisakhale bwino kukweza choyambirira, zomwe zimapangitsa kutayika kwa zinthu zambiri ndikuchedwetsa ntchito ndi makasitomala. Fakitala wa board board adzakumana ndi zotayika zazikulu monga kuchotsedwa, kuthandizira zinthu, komanso kutaya makasitomala. Ndiye ndi mbali ziti zomwe timayamba nazo tikakumana ndi mafunso otere? Nthawi zambiri timasanthula ngati ndi data ya solder resist (inki, masking film); Kodi pali kukayika kulikonse pakasindikiza nsalu ya silika, lamination ndi kuchiritsa; Kodi pali kukayika kulikonse pankhani ya mafuta osankhidwa? dikirani… Chifukwa chake, timakonda kuyitanitsa mainjiniya kuti adziwe chifukwa chake ndikusintha kuchokera kumagawo awa. Timafunsanso ngati nyengo ili? Ndi yonyowa posachedwa, ndipo bolodi limatenga chinyezi? (Gawo la PCB ndi zotchinga ndizosavuta kuyamwa chinyezi) pogwira ntchito mwakhama, zimatha kukolola zina. Ndizokayika kuti athandizidwira kunja kwakanthawi.
