Kusukela ku-PCB World,

Abantu abaningi basebenzisa umbala we-PCB ukuhlukanisa ikhwalithi yebhodi.Eqinisweni, umbala webhodi lomama awuhlangene nokusebenza kwe-PCB.

Ibhodi le-PCB, hhayi ukuthi inani eliphakeme, kulula ukuyisebenzisa.

Umbala we-PCB surface empeleni ungumbala we-solder resist.Ukumelana ne-solder kunganqanda ukwenzeka kokusoda okungalungile kwezingxenye, futhi kubambezele impilo yesevisi yocingo, futhi kuvimbele i-oxidation nokugqwala kwesekethe yedivayisi.

Uma uqonda amabhodi e-PCB ezinkampani ezinkulu ezifana ne-Huawei ne-ZTE, uzothola ukuthi umbala ngokuvamile uluhlaza.Lokhu kungenxa yokuthi ubuchwepheshe obuluhlaza buvuthwe kakhulu futhi bulula.

Ngaphezu kohlaza, umbala we-PCB ungachazwa ngokuthi "izinsimbi namakhwela": omhlophe, ophuzi, obomvu, ohlaza okwesibhakabhaka, imibala ye-matte, ngisho ne-chrysanthemum, onsomi, omnyama, oluhlaza okotshani, njll. Ukuba khona komhlophe, ngoba kuyadingeka ukwenza imikhiqizo yokukhanyisa Imibala esetshenzisiwe, kanye nokusetshenziswa kweminye imibala, ikakhulukazi emikhiqizo yokulebula.Kuso sonke isigaba senkampani kusukela ku-R&D kuya ekufikeni komkhiqizo, kuye ngokusetshenziswa okuhlukene kwe-PCB, ibhodi lokuhlola lingase libe nsomi, ibhodi lokhiye lizoba bomvu, futhi amabhodi angaphakathi ekhompyutha azoba mnyama, aphawulwe ngombala.

Ibhodi le-PCB elivame kakhulu ibhodi eliluhlaza, elibizwa nangokuthi amafutha aluhlaza.I-mask inki yayo endala, eshibhile futhi ethandwa kakhulu.Ngaphezu kobuchwepheshe obuvuthiwe, uwoyela oluhlaza unezinzuzo eziningi:

Ekucutshungulweni kwe-PCB, ukukhiqizwa kwemikhiqizo ye-elekthronikhi kufaka phakathi ukwenziwa kwebhodi kanye nokuchibiyela.Phakathi nenqubo, kunezinqubo eziningana zokungena egumbini lokukhanya eliphuzi, futhi ibhodi le-PCB eluhlaza linomphumela omuhle kakhulu wokubukwa ekamelweni lokukhanya okuphuzi;okwesibili, ekucubunguleni isichibi se-SMT, ithini isetshenziswa.Izinyathelo, ukuphetshwa kanye nokulinganiswa kwe-AOI konke kudinga ukulinganiswa kokuma kokubona, futhi ithuluzi lepuleti eliphansi eliluhlaza linobungane kakhulu ukulihlonza.

Ingxenye yenqubo yokuhlola incike ezisebenzini ukuba ziqaphele (kodwa manje iningi labo lisebenzisa ukuhlola i-flying probe esikhundleni sokwenza okwenziwa ngesandla), ligqolozele ibhodi ngaphansi kokukhanya okunamandla, okuluhlaza okotshani kuwubungane emehlweni.Ama-PCB aluhlaza nawo anobungani bemvelo, futhi ngeke akhiphe amagesi anobuthi lapho egaywa kabusha emazingeni okushisa aphezulu.

Eminye imibala ye-PCB, efana ne-blue and black, ifakwe nge-cobalt ne-carbon, ngokulandelana, ngoba ine-conductivity kagesi ebuthakathaka, futhi kunengozi yesifunda esifushane.

Thatha ibhodi elimnyama njengesibonelo.Emkhiqizweni, ibhodi elimnyama lingase libangele umehluko wombala ngenxa yezinkinga zenqubo nempahla eluhlaza, okuholela esilinganisweni esiphezulu sokukhubazeka kwe-PCB.Imikhondo yebhodi lesifunda elimnyama akulula ukuhlukanisa, okuzokwandisa ubunzima bokugcinwa nokulungiswa kamuva.Amafekthri amaningi e-PCB awasebenzisi ama-PCB amnyama.Ngisho nasemkhakheni wemboni yezempi kanye nokulawulwa kwezimboni, imikhiqizo enezidingo zekhwalithi ephezulu kakhulu isebenzisa ama-PCB substrates aluhlaza.

Okulandelayo, ake sikhulume ngomphumela wombala weyinki yemaski ye-solder ebhodini?

Ngomkhiqizo oqediwe, umphumela wamayinki ahlukene ebhodini ubonakala ngokuyinhloko ekubukeni, okungukuthi, kungakhathaliseki ukuthi kuhle noma cha.Isibonelo, okuluhlaza kuhlanganisa okuluhlaza kwelanga, okuluhlaza okotshani, okuluhlaza okotshani, okuluhlaza okotshani, njll., umbala ulula kakhulu, kulula ukubona ipulaki Ukubukeka kwebhodi ngemuva kwenqubo yembobo akukuhle, kanti abanye abakhiqizi' oyinki abalungile, isilinganiso se-resin nedayi siyinkinga, kuzoba nezinkinga ezinjengamabhamuza, futhi kungatholwa ushintsho oluncane lombala;umthelela emikhiqizweni eseqediwe ubonakala kakhulu Ngokuphathelene nobunzima bokukhiqiza, le nkinga iyinkimbinkimbi ukuyichaza.Oyinki bemibala abahlukene banezinqubo ezihlukene zokufaka imibala, njengokufafaza nge-electrostatic, ukufutha, nokuphrinta isikrini.I-inki ratio nayo ihlukile.Iphutha elincane lizokwenza ukuthi umbala uvele.inkinga.

Nakuba umbala we-inki ungenawo umthelela ebhodini le-PCB, ukujiya kukayinki kunomthelela omkhulu esikhumbeni, ikakhulukazi ebhodini legolide lamanzi, elinokulawula okuqinile ngokwedlulele kubukhulu bukayinki;ubukhulu kanye nama-bubbles kayinki obomvu kulula ukulawula, futhi inkino ebomvu ihlanganisa Emgqeni, ezinye iziphambeko zingambozwa, futhi ukubukeka kuhle kakhulu, kodwa into embi ukuthi intengo ibiza kakhulu.Uma uthwebula izithombe, ukuchayeka okubomvu nokuphuzi kuzinza kakhulu, futhi okumhlophe yikho okunzima kakhulu ukukulawula.

Ukufingqa, umbala awunawo umthelela ekusebenzeni kwebhodi eliqediwe, futhi unomthelela omncane kumhlangano we-PCB nezinye izixhumanisi;ekwakhiweni kwe-PCB, yonke imininingwane ekusixhumanisi ngasinye ilawulwa ngokuqinile, futhi ibhodi le-PCB liba Ukhiye webhodi elihle.Amabhodi omama e-PCB anemibala ehlukene angowokuthengiswa komkhiqizo.Akunconywa ukuthi usebenzise umbala njengokucatshangelwa okubalulekile ekucubunguleni kwe-PCB.
