Enqubweni yokuthuthukiswa komkhiqizo we-elekthronikhi, ukuhlolwa kwe-PCB kuyisixhumanisi esibalulekile.Ngokuthuthuka kobuchwepheshe kanye nokwenyuka kwesidingo semakethe, izinsizakalo ze-PCB prototyping ezisheshayo zingathuthukisa kakhulu isivinini sokwethulwa komkhiqizo kanye nokuncintisana.Ngakho-ke, yini i-PCB board board service prototyping ifaka phakathi?
Amasevisi wokubuyekeza ubunjiniyela
Ezigabeni zokuqala ze-PCB prototyping, izinsizakalo zokubuyekezwa konjiniyela zibalulekile.Izinsizakalo zokubukeza ubunjiniyela zibandakanya onjiniyela abangochwepheshe ababuyekeza imidwebo yedizayini ukuze baqinisekise ukuthi bayahlangabezana nokucaciswa kwedizayini kanye nezidingo zokukhiqiza.Ngokuklama kwangaphambi kwesikhathi nokubuyekezwa kobunjiniyela, amaphutha ekukhiqizeni okulandelayo angancishiswa, izindleko zehliswe, futhi umjikelezo wokuthuthukiswa ufinyezwe.
Ukukhetha impahla kanye nezinsiza zokuthenga
Ukukhetha okubalulekile kungenye yezixhumanisi ezibalulekile ku-PCB prototyping.Imikhiqizo ehlukene ye-elekthronikhi inezidingo zezinto ezihlukile.Kuyadingeka ukukhetha isisekelo esifanelekile, ukujiya kwe-copper foil kanye nendlela yokwelashwa kwendawo ngokuya ngesimo sohlelo oluthile.Ama-substrates avamile afaka i-FR-4, ama-aluminium substrates, nezinto ezisebenza ngamaza aphezulu.Izinkampani zesevisi ye-prototyping esheshayo ngokuvamile zihlinzeka ngempahla yezinto ezihlukahlukene ukuze zihlangabezane nezidingo zamakhasimende ahlukene.
Amasevisi okukhiqiza
1. Ukudlulisa iphethini: Gcoba ungqimba lwezinto ezizwelayo (njengefilimu eyomile noma ifilimu emanzi) ku-foil yethusi, bese usebenzisa ukukhanya kwe-UV noma i-laser ukuze uveze iphethini, bese ususa izingxenye ezingadingekile ngenqubo yokuthuthukisa.
2. I-Etching: Susa i-foil yethusi eyeqile ngokusebenzisa isixazululo samakhemikhali noma ubuchwepheshe bokufaka i-plasma, ushiye iphethini yesifunda edingekayo kuphela.
3. Ukubhoboza nokucwenga: Geza okuhlukahlukene okudingekayo emigodini nasezimbotsheni eziyimpumputhe/ezingcwatshiwe ebhodini, bese uqhuba i-electroplating ukuze uqinisekise ukuqhutshwa kodonga lwembobo.
4. I-Lamination kanye ne-lamination: Kumabhodi anezingqimba eziningi, ungqimba ngalunye lwamabhodi wesifunda kudingeka luhlanganiswe ne-resin futhi lucindezelwe ngaphansi kwezinga lokushisa eliphezulu nokucindezela okukhulu.
5. Ukwelashwa kwendawo: Ukuze kuthuthukiswe ukushisela nokuvimbela i-oxidation, ukwelashwa kwendawo ngokuvamile kwenziwa.Izindlela zokwelapha ezijwayelekile zifaka i-HASL (i-hot air leveling), i-ENIG (i-gold plating) kanye ne-OSP (ukuvikelwa kwe-organic coating).
izinsiza zokuluma nokuhlola
1. Ukuhlolwa kokusebenza: Sebenzisa isihloli esindizayo noma isitendi sokuhlola ukuze uhlole indawo ngayinye yokuxhunywa kukagesi ebhodini lesekethe ukuze uqinisekise ukuthi ukuqhubeka nokwahlukanisa kuhlangabezana nezidingo zokuklama.
2. Ukuhlolwa kokubukeka: Ngosizo lwesibonakhulu noma imishini yokuhlola okuzenzakalelayo (AOI), hlola ngokuqinile ukubukeka kwebhodi le-PCB ukuze uthole futhi ulungise noma yikuphi ukukhubazeka okungase kuphazamise ukusebenza.
3. Ukuhlola okusebenzayo: Amanye amabhodi esekethe ayinkimbinkimbi kakhulu nawo adinga ukuhlolwa ngokusebenza ukuze alingise indawo yokusetshenziswa yangempela futhi ahlole ukuthi ukusebenza kwawo kuyahlangabezana yini nalokho okulindelekile.
Izinsizakalo zokupakisha nezokuthumela
Amabhodi e-PCB adlula ukuhlolwa nokuhlolwa adinga ukupakishwa kahle ukuze avimbele ukulimala ngesikhathi sokuthutha.Ukupakishwa okunikezwa izinsizakalo ze-prototyping ezisheshayo ngokuvamile kufaka phakathi ukupakisha okulwa nokuma, ukupakisha okungangenwa ukushaqeka, nokupakisha okungangeni manzi.Ngemuva kokuthi ukupakishwa sekuqediwe, inkampani yesevisi yokuqinisekisa izoletha imikhiqizo ngokushesha kumakhasimende ngokudiliva okucacile noma ngohlelo oluzinikele ukuze kuqinisekiswe ukuthi ucwaningo nenqubekelaphambili yentuthuko ayithinteki.
Ukwesekwa kobuchwepheshe kanye nesevisi yangemuva kokuthengisa
Izinsizakalo ze-prototyping ezisheshayo ze-PCB azihlinzeki kuphela ngokukhiqiza nokukhiqiza, kodwa futhi zihlanganisa ukwesekwa okupheleleyo kwezobuchwepheshe kanye nesevisi yangemuva kokuthengisa.Lapho ehlangabezana nezinkinga noma ukungaqiniseki phakathi nenqubo yokuklama, amakhasimende angaxhumana nethimba losekelo lobuchwepheshe noma kunini ukuze athole ukuqondiswa kochwepheshe nezeluleko.Ngisho nangemva kokulethwa komkhiqizo, uma amakhasimende ehlangabezana nanoma yiziphi izinkinga zekhwalithi noma edinga ukulungiselelwa okwengeziwe, ithimba lesevisi yangemuva kokuthengisa lizosabela ngokushesha futhi lizixazulule, liqinisekise ukwaneliseka nokwethenjwa kwamakhasimende.
Isevisi ye-PCB yebhodi ye-prototyping esheshayo ihlanganisa izici eziningi kusukela ekubuyekezweni kwephrojekthi, ukukhethwa kwezinto ezibonakalayo, ukukhiqizwa nokukhiqizwa kuya ekuhlolweni, ukupakisha, ukulethwa kanye nesevisi yangemuva kokuthengisa.Ukusebenza kahle nokuxhumeka okungenamthungo kwesixhumanisi ngasinye akukwazi nje ukuthuthukisa kakhulu ukusebenza kahle kwe-R&D, kodwa futhi kunciphise izindleko zokukhiqiza futhi kuthuthukise ikhwalithi yomkhiqizo.
