Kwinkqubo yophuhliso lwemveliso ye-elektroniki, ubungqina be-PCB likhonkco elibalulekileyo.Ngokuqhubela phambili kwetekhnoloji kunye nokwanda kwemfuno yentengiso, iinkonzo ze-PCB ezikhawulezayo zokuchwetheza zinokusiphucula kakhulu isantya sokuqaliswa kwemveliso kunye nokhuphiswano.Ke, ibhodi yePCB inkonzo ekhawulezayo yokwenziwa kweprototyping ibandakanya ntoni?
Iinkonzo zokuphonononga ubunjineli
Kumanqanaba okuqala e-PCB prototyping, iinkonzo zophononongo lobunjineli zibalulekile.Iinkonzo zokuphononongwa kobunjineli zibandakanya iinjineli eziqeqeshelwe ukuphonononga imizobo yoyilo ukuqinisekisa ukuba ziyahlangabezana neenkcukacha zoyilo kunye neemfuno zokwenziwa.Ngoyilo lwangaphambili kunye nophononongo lobunjineli, iimpazamo kwimveliso elandelayo zinokuncitshiswa, iindleko zincitshiswe, kwaye umjikelo wophuhliso ufinyeziwe.
Ukukhethwa kwezinto eziphathekayo kunye neenkonzo zokuthenga
Ukukhetha izinto eziphathekayo lelinye lamakhonkco aphambili kwiprototyping yePCB.Iimveliso zombane ezahlukeneyo zineemfuno zezinto ezahlukeneyo.Kuyimfuneko ukuba ukhethe izinto ezisisiseko ezifanelekileyo, ubukhulu be-foil yobhedu kunye nendlela yonyango yomhlaba ngokwemeko yesicelo esithile.Ii-substrates eziqhelekileyo ziquka i-FR-4, i-aluminium substrates, kunye nezixhobo eziphezulu ze-frequency.Iinkampani zenkonzo yeprototyping ekhawulezayo zihlala zibonelela ngoluhlu lwezixhobo ezahlukeneyo ukuhlangabezana neemfuno zabathengi abohlukeneyo.
Iinkonzo zokuvelisa
1. Ukudluliselwa kwepateni: Gcoba umaleko wezinto ezibonisa ukukhanya (ezifana nefilimu eyomileyo okanye ifilimu emanzi) kwi-foil yobhedu, emva koko usebenzise ukukhanya kwe-UV okanye i-laser ukuveza ipateni, kwaye emva koko ususe iindawo ezingeyomfuneko ngenkqubo yophuhliso.
2. I-Etching: Susa i-foil yobhedu engaphezulu ngesisombululo sekhemikhali okanye iteknoloji ye-plasma etching, ushiye kuphela iphethini yesekethe efunekayo.
3. Ukugrumba kunye nokucwenga: Gcoba izinto ezahlukeneyo ezifunekayo kwimingxunya kunye nemingxuma eyimfama / engcwatyiweyo ebhodini, kwaye emva koko uqhube i-electroplating ukuqinisekisa ukuqhutywa kodonga lomngxuma.
4. I-Lamination kunye ne-lamination: Kwiibhodi ze-multi-layer, i-layer nganye yeebhodi zeesekethe kufuneka idityaniswe kunye ne-resin kwaye icinezele phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu.
5. Unyango oluphezulu: Ukuze kuphuculwe i-weldability kunye nokuthintela i-oxidation, unyango olungaphezulu luyenziwa ngokuqhelekileyo.Iindlela zonyango eziqhelekileyo ziquka i-HASL (i-hot air leveling), i-ENIG (i-gold plating) kunye ne-OSP (ukhuseleko lwe-coating organic).
uhlaba kunye neenkonzo zokuhlola
1. Uvavanyo lokusebenza: Sebenzisa i-flying probe tester okanye i-test stand ukuvavanya indawo nganye yokudibanisa umbane kwibhodi yesekethe ukuqinisekisa ukuba ukuqhubeka kunye nokugquma kuyahlangabezana neemfuno zoyilo.
2. Ukuhlolwa kwembonakalo: Ngoncedo lwe-microscope okanye izixhobo zokuhlola ezizenzekelayo (i-AOI), hlola ngokungqongqo ukubonakala kwebhodi ye-PCB ukufumanisa kunye nokulungisa naziphi na iziphene ezinokuchaphazela ukusebenza.
3. Uvavanyo olusebenzayo: Ezinye iibhodi zeesekethe ezintsonkothileyo nazo kufuneka zivavanywe ngokusebenzayo ukulinganisa eyona ndawo isetyenziswayo kunye nokuvavanya ukuba ukusebenza kwazo kuyahlangabezana na nokulindelweyo.
Ukupakisha kunye neenkonzo zokuthumela ngenqanawa
Iibhodi zePCB eziphumelele uvavanyo kunye nokuhlolwa kufuneka zipakishwe ngokufanelekileyo ukukhusela umonakalo ngexesha lokuthutha.Ukupakishwa okubonelelwa ngeenkonzo zeprototyping ezikhawulezayo ngokuqhelekileyo kubandakanya ukupakishwa kwe-anti-static, ukupakishwa kobungqina bokuthuthumela, kunye nokupakishwa kwamanzi.Emva kokuba ukupakishwa kugqityiwe, inkampani yenkonzo yobungqina iya kuzisa ngokukhawuleza iimveliso kubathengi ngokuhambisa okucacileyo okanye ukunikezelwa kwezinto ezinikezelweyo ukuqinisekisa ukuba uphando kunye nenkqubela phambili yophuhliso ayichaphazeleki.
Inkxaso yobugcisa kunye nenkonzo emva kokuthengisa
Iinkonzo zeprototyping ezikhawulezayo zePCB aziboneleli kuphela ngemveliso kunye nemveliso, kodwa zikwabandakanya inkxaso ebanzi yobugcisa kunye nenkonzo emva kokuthengisa.Xa uhlangabezana neengxaki okanye ukungaqiniseki ngexesha lenkqubo yokuyila, abathengi banokuqhagamshelana neqela lenkxaso yobugcisa nangaliphi na ixesha ukufumana isikhokelo sobuchule kunye neengcebiso.Nasemva kokuba imveliso ihanjiswe, ukuba abathengi bahlangabezana nazo naziphi na iingxaki ezisemgangathweni okanye bafuna ukuphuculwa ngakumbi, iqela lenkonzo emva kokuthengisa liya kuphendula ngokukhawuleza kwaye lizisombulule, liqinisekisa ukwaneliseka kwabathengi kunye nokuthembela.
Ibhodi yePCB yenkonzo yokucofa ngokukhawuleza ibandakanya imiba emininzi ukusuka kuphononongo lweprojekthi, ukukhetha imathiriyeli, imveliso kunye nokuveliswa ukuya kuvavanyo, ukupakishwa, ukuhanjiswa kunye nenkonzo emva kokuthengisa.Ukuphunyezwa ngokufanelekileyo kunye nokuxhamla ngokungenamthungo kwikhonkco nganye akunakuphucula kakhulu ukusebenza kwe-R & D, kodwa nokunciphisa iindleko zokuvelisa kunye nokuphucula umgangatho wemveliso.
