Emhlabeni othuthukayo wezinto zikagesi, isidingo se-PCB esebenza kahle asikaze sibe sikhulu. Phakathi kwezinhlobo ezahlukene ze-PCB, i-PCB enezingqimba eziyisi-6 igqama ngenxa yekhono layo lokwamukela ukujikeleza okuyinkimbinkimbi ngenkathi igcina i-compact form factor. Lesi sihloko sidingida ubunkimbinkimbi be-6L PCB, ikakhulukazi lezo ezinezimbobo ezingaboni, futhi sihlola indima yabakhiqizi be-PCB ekuletheni imikhiqizo yekhwalithi ephezulu enezindawo ezithuthukisiwe ezifana ne-EING.
Ukuqonda i-6L PCB
I-PCB enezingqimba ezi-6 iqukethe izendlalelo ze-conductive eziyisithupha ezihlukaniswe izinto ezifaka i-insulating. Lokhu kulungiselelwa kwezendlalelo eziningi kuvumela ukwanda kokuminyana kwesekethe, kukwenze kube kuhle ezinhlelweni zokuxhumana ngocingo, ugesi wabathengi, kanye nezinhlelo zezimoto. Izendlalelo zivame ukuhlelwa ngohlelo oluthile ukuze kuthuthukiswe ubuqotho besignali futhi kuncishiswe ukuphazamiseka kwe-electromagnetic (EMI).
Ukwakhiwa kwe-6L PCB kuhilela izinqubo ezimbalwa ezibucayi, okuhlanganisa ukupakishwa kwezingqimba, ukucwiliswa, ukubhoboza, nokunamathisela. Isinyathelo ngasinye kufanele senziwe ngokunemba ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nezidingo eziqinile zemishini yesimanje kagesi.
Ukubaluleka Kwezimbobo Ezingaboni
Esinye sezici ezintsha ezingafakwa ku-6L PCB ukusetshenziswa kwezimbobo ezingaboni. Imbobo eyimpumputhe iyimbobo engahambi yonke indlela ngePCB; ixhuma isendlalelo esisodwa noma ngaphezulu kodwa ayibonakali ngakolunye uhlangothi. Lesi sici sokuklama sizuzisa kakhulu amasignali omzila kanye noxhumo lwamandla ngaphandle kokuphazamisa ubuqotho bubonke bebhodi.
Izimbobo ezingaboni zingasiza ekunciphiseni ukunyathela kwebhodi, okuvumela amadizayini aminyene kakhulu. Futhi zisiza ukuphathwa okungcono kokushisa ngokunikeza izindlela zokuqeda ukushisa. Nokho, ukwakhiwa kwezimbobo eziyizimpumputhe kudinga amasu athuthukile nokunemba, okwenza kube semqoka ukusebenzisana nomkhiqizi we-PCB ohlonishwayo.
Iqhaza Labakhi be-PCB
Ukukhetha umkhiqizi we-PCB ofanele kubalulekile ukuze kuzuzwe ama-PCB angu-6L ekhwalithi ephezulu anezimbobo ezingaboni. Umkhiqizi onokwethenjelwa uzoba nekhono elidingekayo, ubuchwepheshe, kanye nezinyathelo zokulawula ikhwalithi ukuze aqinisekise ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso zomkhakha.
Lapho ukhetha umkhiqizi we-PCB, cabangela izici ezilandelayo:
Isipiliyoni kanye Nobungcweti: Bheka abakhiqizi abanerekhodi elifakazelwe ekukhiqizeni ama-PCB anezingqimba eziningi, ikakhulukazi lawo anobuchwepheshe be-blind hole.
Ubuchwepheshe Nezisetshenziswa:Izinqubo zokukhiqiza ezithuthukisiwe, ezifana nokubhola nge-laser kanye nokuhlola okuzenzakalelayo (AOI), zibalulekile ekudaleni izimbobo ezingaboni kahle.
Ukuqinisekisa ikhwalithi:Umkhiqizi ohloniphekile uzosebenzisa izinyathelo eziqinile zokulawula ikhwalithi, okuhlanganisa ukuhlola ukusebenza kukagesi nobuqotho bemishini.
Izinketho zokwenza ngokwezifiso:Ikhono lokwenza imiklamo ngendlela oyifisayo, okuhlanganisa ubukhulu nokubekwa kwezimbobo ezingaboni, kubalulekile ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi.
I-Resin Plug Holes: Isixazululo Sezimbobo Eziyimpumputhe
Ukuthuthukisa ukusebenza kwama-PCB angu-6L anezimbobo ezingaboni, abakhiqizi bavame ukusebenzisa izimbobo zepulaki ye-resin. Le nqubo ihlanganisa ukugcwalisa izimbobo eziyimpumputhe nge-resin material, esebenza ngezinhloso eziningi:
Ukuhlukaniswa kukagesi:Izimbobo zepulaki ye-resin zisiza ukuvimbela izikhindi zikagesi phakathi kwezendlalelo, ziqinisekisa ukusebenza okuthembekile.
Ukuzinza Kwemishini: I-resin yengeza ubuqotho besakhiwo ku-PCB, iyenze imelane kakhulu nengcindezi yemishini.
I-Surface Finish: EING
Ukuqedwa okungaphezulu kwe-PCB kuyisici esibalulekile esithonya ukusebenza nokuthembeka kwayo. I-EING iyinketho ethandwayo phakathi kwabakhiqizi ngenxa yezakhiwo zayo ezihlukile. Lokhu kuqedwa kuhilela inqubo enezinyathelo ezimbili: i-electroless nickel plating elandelwa ukucwiliswa kwegolide.
Izinzuzo ze-EING:
I-Solderability:I-EING inikeza indawo eyisicaba, elinganayo ethuthukisa ukuthengiselana, okwenza kube lula ukunamathisela izingxenye ngesikhathi sokuhlanganiswa.
Ukumelana Nokugqwala:Ungqimba lwegolide luvikela i-nickel engaphansi ekufakweni kwe-oxidation, iqinisekisa ukwethembeka kwesikhathi eside ezimweni ezihlukahlukene zemvelo.
Ukucaba:Indawo ebushelelezi ye-EING ilungele izingxenye ezinephimbo elihle, ezivame ukwanda kuma-electronics wesimanje.
Ukuhambisana:I-EING iyahambisana nezinto ezihlukahlukene ze-PCB futhi ingasetshenziswa kumabhodi anezimbobo eziyizimpumputhe, okuqinisekisa ukuhlanganiswa okungenamthungo kwezakhi zokuklama.
