Ibibazo n'ibisubizo bikunze kubazwa
1. Ibisobanuro by'urutoki rwa Zahabu
Urutoki rwa zahabu, ruzwi kandi nka edge connector, ni igikoresho gishyira impera imwe ya PCB mu mwanya w'urutoki. Gikoresha udupira two guhuza nk'aho PCB ihurira kugira ngo igere ku bushobozi bwo kuyobora hagati y'agapira ko gusoda cyangwa urupapuro rw'umuringa n'udupira two gushyiramo. Kugira ngo rwongere ubushobozi bwo kuyobora, kudasiga ogisijeni no kudashira, intoki za zahabu zikunze kuvurwa na nickel gold plating cyangwa ENIG. Bitewe n'imiterere yacyo isa n'urutoki, cyitwa Gold Finger.
2. Uburyo bwo kurangiza ubuso bwa PCB z'intoki za zahabu
Uburyo bwo kurangiza ubuso bwa Gold Finger PCB ni ingenzi cyane ku mikorere yayo n'aho ikoreshwa. Ubu buryo bubiri busanzwe ni ubu:
1) Igipfunyika cya zahabu cya nikeli
Gushyira zahabu ya nikeli ni uburyo busanzwe bwo kurangiza ubuso, kandi ubunini bwayo bushobora kugera kuri santimetero 1.50. Ifite ubushobozi bwo gutwara ibintu, kurwanya ogisijeni no kudashira, bityo ikoreshwa cyane ku bikoresho bya zahabu bisaba gushyirwamo no gukurwaho kenshi cyangwa ibikoresho bya mudasobwa bisaba gukururwa kenshi. Ariko, bitewe n'igiciro kinini cya zahabu, gukoresha zahabu ya nikeli nikeli bikunze gukoreshwa gusa mu gutunganya ahantu nk'intoki za zahabu. Ubuso bw'ubu buryo bwo kurangiza ubuso ni umweru wa feza, ariko ubushobozi bwo gusonerwamo ni buke gato.
2) NDEMERA
ENIG ni ubundi buryo busanzwe bwo kurangiza ubuso, bufite ubunini bwa santimetero 1 na santimetero 3. ENIG ifite ubushobozi bwo gutwara ibintu neza, uburyo bworoshye bwo gutunganya ubuso no gusonerwa, bigatuma ikoreshwa cyane muri PCB zifite imiterere myiza cyane hamwe n'imiterere nka keyway, bound IC, BGA, nibindi. Ku PCB za zahabu zidasaba imbaraga zo kwangirika cyane, inzira yose ya ENIG ishobora no guhitamo, ifite igiciro gito cyane. Ubuso bwa ENIG burangiye ni umuhondo wa zahabu.
3. Amabwiriza yo kwirinda gukoresha intoki za zahabun
Mu gushushanya PCB y'urutoki rwa zahabu, hari ingingo z'ingenzi zigomba kwitabwaho cyane cyane:
1) Ubushobozi bwo kwambara nk'urutoki rwa zahabu
Ku bikoresho bya PCB bisaba gushyirwaho no gukurwaho kenshi, kugira ngo byongere ubushobozi bwo kwangirika kw'intoki za zahabu, ubusanzwe ni ngombwa gukoresha electroplating ikomeye ya zahabu.
2) Gutera urutoki rwa zahabu
Ubusanzwe intoki za zahabu zikenera gukururwa, zifite inguni rusange ya 45°. Kuba hari udukoko dushobora kugabanya ibyago bishobora kubaho, nk'uko bigaragara ku ishusho.
3) Idirishya rifunguye kugira ngo habeho maske ikoreshwa mu gupfuka
Agapfunyika k'urutoki rwa zahabu gakeneye gupfundikirwa idirishya ku gice cyose cya maske yo gupfundikirwa, hatabayeho gukoresha utwuma tw'icyuma.
4) Intera iri hagati y'agapfukamunwa gasoda n'urutoki rwa zahabu
Intera iri hagati y’urutoki rwa solder n’urutoki rwa zahabu igomba kubahiriza ibisabwa, akenshi bisaba ko urutoki rwa solder rugomba kuba nibura mm 1 uvuye aho urutoki rwa zahabu ruri, harimo no gukoresha urutoki rwa solder.
5) Irangi ry'urutoki rwa zahabu
Ubuso bw'urutoki rwa zahabu ntibugomba gutwikirwa n'umuringa.
6) Uburyo bwo gutema umuringa
Ibyiciro byose by'imbere by'urutoki rwa zahabu bisaba gutema umuringa, akenshi bifite ubugari bwa mm 3. Ibi bishobora kugabanya itandukaniro hagati y'urutoki rwa zahabu n'umurongo wa impedance, ndetse bikanafasha ESD.
Ibi byavuzwe haruguru ni ibintu byinshi bigomba kwitabwaho by'umwihariko mu gushushanya PCB y'urutoki rwa zahabu kugira ngo hamenyekane ko urutoki rwa zahabu rukora neza kandi rukora neza.
4. Amabwiriza yo kwirinda gutunganya urutoki rwa zahabu
Niba uteganya gukoresha PCB y'intoki za zahabu, ibi bikurikira ni bimwe mu byo ugomba gukora mu gihe cyo gutunganya PCB ya Rich Full Joy:
1. Ubunini bwa PCB bushobora guhindurwa ni hagati ya mm 1.2 na mm 2.4. PCB zifite ubunini butari muri uru rwego ntizishobora guhindurwa.
2. Ubujyakuzimu n'inguni by'inkombe zigoswe ubusanzwe biri hagati ya 20° na 45°. Intera iri hagati y'urutoki rwa zahabu n'inkombe ya PCB igomba kuba ihagije, muri rusange isabwa kuba hagati ya 0.6m na 1.5mm, kugira ngo hirindwe kwangiza urutoki rwa zahabu.
Rich Full Joy inzobere mu gutunganya PCB z'intoki za zahabu kugira ngo igire ubuziranenge n'ubwizerwe. Uburyo bwacu bushobora kuzuza ibisabwa bitandukanye mu gushushanya no gutanga umusaruro mwiza ku mushinga wawe.
PCB z'intoki za zahabu zigira uruhare runini mu ikoranabuhanga rigezweho, kandi kwizerwa kwazo n'imikorere yazo biterwa n'uburyo bwo kurangiza ubuso n'ibisobanuro birambuye ku gishushanyo. Mu guhitamo uburyo bukwiye bwo gutunganya no kwita ku bintu by'ingenzi by'ingenzi mu gushushanya, birashoboka kwemeza ko PCB z'intoki za zahabu zigira imikorere myiza mu bikorwa bitandukanye. Niba ukeneye serivisi nziza zo gutunganya PCB z'intoki za zahabu, nyamuneka tekereza kuri Ruizhi Xinfeng, kandi tuzishimira kuguha ubufasha.
