M'dziko lomwe likukula mwachangu lamagetsi, kufunikira kwa PCB yochita bwino kwambiri sikunakhalepo kwakukulu. Pakati pa mitundu yosiyanasiyana ya PCB, 6-wosanjikiza PCB imadziwika bwino chifukwa cha kuthekera kwake kutengera madera ovuta ndikusunga mawonekedwe ophatikizika. Nkhaniyi ikufotokoza zovuta za 6L PCB, makamaka zomwe zili ndi mabowo akhungu, ndikuwunikanso ntchito ya opanga ma PCB popereka zinthu zapamwamba kwambiri zomaliza ngati EING.
Kumvetsetsa 6L PCB
PCB ya 6-wosanjikiza imakhala ndi zigawo zisanu ndi chimodzi zosiyanitsidwa ndi zida zotetezera. Kukonzekera kwamitundu yambiriku kumapangitsa kuti kachulukidwe wozungulira achuluke, ndikupangitsa kukhala koyenera kugwiritsa ntchito matelefoni, zamagetsi zamagetsi, ndi makina amagalimoto. Zigawozo nthawi zambiri zimasanjidwa mwadongosolo kuti zitsimikizire kukhulupirika kwa ma siginecha ndikuchepetsa kusokoneza kwa electromagnetic (EMI).
Kupanga kwa 6L PCB kumaphatikizapo njira zingapo zofunika, kuphatikizapo kusanjikiza, kupukuta, kubowola, ndi etching. Gawo lirilonse liyenera kuchitidwa mwatsatanetsatane kuonetsetsa kuti chomaliza chikukwaniritsa zofunikira pazida zamakono zamakono.
Kufunika kwa Mabowo Akhungu
Chimodzi mwazinthu zatsopano zomwe zitha kuphatikizidwa mu 6L PCB ndikugwiritsa ntchito mabowo akhungu. Bowo lakhungu ndi dzenje lomwe silidutsa mu PCB; imalumikiza zigawo imodzi kapena zingapo koma siziwoneka mbali inayo. Kapangidwe kameneka kamakhala kopindulitsa kwambiri pamayendedwe amasigino ndi kulumikizana ndi mphamvu popanda kusokoneza kukhulupirika kwa bolodi.
Mabowo osawona angathandize kuchepetsa kaphatikizidwe ka bolodi, kulola kuti pakhale mapangidwe ophatikizika. Amathandiziranso kasamalidwe kabwino ka kutentha popereka njira zochepetsera kutentha. Komabe, kupanga mabowo akhungu kumafuna njira zapamwamba komanso zolondola, zomwe zimapangitsa kukhala kofunikira kuyanjana ndi wopanga ma PCB odziwika bwino.
Udindo wa Opanga PCB
Kusankha wopanga PCB woyenera ndikofunikira kuti mukwaniritse ma PCB apamwamba kwambiri a 6L okhala ndi mabowo akhungu. Wopanga wodalirika adzakhala ndi ukadaulo wofunikira, ukadaulo, komanso njira zowongolera kuti awonetsetse kuti chomaliza chikukwaniritsa miyezo yamakampani.
Posankha wopanga PCB, ganizirani izi:
Zochitika ndi Katswiri: Yang'anani opanga omwe ali ndi mbiri yotsimikizika popanga ma PCB amitundu yambiri, makamaka omwe ali ndiukadaulo wamabowo akhungu.
Tekinoloje ndi Zida:Njira zopangira zapamwamba, monga kubowola ndi laser ndi automated optical inspection (AOI), ndizofunikira popanga mabowo akhungu enieni.
Chitsimikizo chadongosolo:Wopanga odziwika adzakhazikitsa njira zowongolera bwino, kuphatikiza kuyesa magwiridwe antchito amagetsi ndi kukhulupirika kwamakina.
Zokonda Zokonda:Kutha kusintha mapangidwe, kuphatikiza kukula ndi kuyika mabowo osawona, ndikofunikira kuti mukwaniritse zofunikira za polojekiti.
Resin Plug Holes: Njira Yothetsera Mabowo Akhungu
Kupititsa patsogolo magwiridwe antchito a 6L PCB okhala ndi mabowo akhungu, opanga nthawi zambiri amagwiritsa ntchito mabowo a pulagi utomoni. Njirayi imaphatikizapo kudzaza mabowo akhungu ndi utomoni, womwe umagwira ntchito zingapo:
Kudzipatula kwa Magetsi:Mabowo a pulagi a resin amathandizira kupewa akabudula amagetsi pakati pa zigawo, kuonetsetsa kuti magwiridwe antchito odalirika.
Kukhazikika Kwamakina: Utomoni umawonjezera kukhulupirika kwa PCB, ndikupangitsa kuti ikhale yolimba kupsinjika kwamakina.
Kumaliza Pamwamba: EING
Mapeto a PCB ndi chinthu chofunikira kwambiri chomwe chimakhudza magwiridwe ake komanso kudalirika kwake. EING ndi chisankho chodziwika pakati pa opanga chifukwa cha mawonekedwe ake apadera. Kutsirizitsaku kumaphatikizapo njira ziwiri: plating ya nickel yopanda electroless yotsatiridwa ndi kumizidwa kwagolide.
Ubwino wa EING:
Solderability:EING imapereka malo athyathyathya, ngakhale pamwamba omwe amawonjezera kusungunuka, kuti zikhale zosavuta kumangirira zigawo panthawi ya msonkhano.
Kulimbana ndi Corrosion:Golide wosanjikiza wa golide amateteza nickel wapansi ku okosijeni, kuonetsetsa kudalirika kwa nthawi yayitali muzochitika zosiyanasiyana zachilengedwe.
Kutsika:Malo osalala a EING ndi abwino pazigawo zowoneka bwino, zomwe zikuchulukirachulukira mumagetsi amakono.
Kugwirizana:EING imagwirizana ndi zida zosiyanasiyana za PCB ndipo ingagwiritsidwe ntchito pamatabwa okhala ndi mabowo akhungu, kuwonetsetsa kusakanikirana kosasinthika kwazinthu zamapangidwe.
