Uruganda rwa PCB n'Uruganda rwa PCBA
PCBA y'inganda - Ibibaho byo kuzenguruka by'imashini zigenzura imikorere y'inganda
PCBA y'inganda, izwi kandi nka board igenzura imikorere y'inganda, ni board igenzura imikorere y'inganda igamije kwihanganira impanuka, guhinda umushyitsi, ubushyuhe bukabije, ubushuhe n'umukungugu mu bikoresho by'inganda. Iyi PCBA ikoreshwa mu gukora ibikorwa byinshi mu nganda zigenzura imikorere y'inganda. Yagenewe gushyiraho circuit y'umushinga mu buryo buciriritse, butuma umuriro utembera neza mu nzira ikenewe kandi bukongera imikorere y'ibicuruzwa. Izi board kandi ni ingenzi mu mishinga n'ibikoresho bigenzura imikorere y'inganda, bifasha gupima no gushyiraho ibipimo byinshi by'umurongo w'iteraniro, no kubona ingano nyayo y'umubiri.
Isosiyete y'ibikoresho by'inganda PCBA - Richpcba
Niba ushaka imbuga za PCB/PCBA zo kugenzura ibikoresho by’inganda nziza ku giciro gito, www.richpcba.com niyo nzira nziza kurusha izindi. Twashinzwe i Shenzhen, mu Bushinwa mu 2004, turi uruganda rukora PCB rukora ibikoresho byagutse rwakoreye ibihumbi by’ibigo byo mu gihugu no mu mahanga mu myaka mike ishize. Serivisi zacu zo gukora ntabwo ari PCB na PCBA gusa; tunashyira mu bikorwa ibisabwa byihariye, kuvugurura no guhindura ibisabwa n’abakiriya ku buryo babyishimiye. Binyuze mu mirimo yacu y’umwuga n’imyifatire y’akazi, twamenyekanye n’inganda nyinshi zikomeye mu rwego rw’inganda.
Twibanda ku gukora PCB z’inganda zifite ibyiciro byinshi kandi dutanga serivisi za PCBA imwe imwe. Inzira yacu itangirira kuri dosiye cyangwa Gerber yoherejwe n'umukoresha. Nyuma yo kwakira iyi dosiye, injeniyeri zacu zisuzuma kandi zigashyiraho inzira yo gukora kugira ngo zikore ibibaho bya PCB n'ibintu bya PCBA byo kugenzura inganda hakoreshejwe ikoranabuhanga ritandukanye. RICHPCBA ishobora kuzuza ibisabwa n'abakiriya ku mishinga yoroshye kugeza ku igoye, amashami mato kugeza ku matsinda menshi ya PCB, ndetse n'ibigo bishya kugeza ku bigo binini by'inganda. Itsinda ryacu ry'inzobere rikora imishinga binyuze mu bayobozi b'imishinga ya 1V1, bafashijwe n'amatsinda ashinzwe amasoko, ubwubatsi, inganda, n'ubuziranenge.

Ibintu bifitanye isano n'imiterere ya PCB mu nganda
Imiterere y'ibice
Gushyira ibice ku miterere y'ikibaho ni ikintu cy'ingenzi cyo kwitaho mu gihe cyo gushushanya imbaho za PCB zigenzura imikorere y'inganda. Gushyira ibice mu buryo budakwiye bishobora kugira ingaruka ku bwizerwe n'imikorere y'umusaruro wa nyuma. Mu gihe cyo gushushanya imbaho za PCB, hagomba kwitabwaho cyane kugira ngo ibice bishyirwe ku kibaho gifite nibura umwanya wa mililitiro 100 hagati y'inkombe z'ikibaho n'ibice bigishyizwemo. Ibi byemeza ko ingano y'ikibaho n'imyobo bigishyizwemo bihuye.
EMI na RFI
Mu nganda, ni ngombwa kugabanya ingaruka za Electromagnetic Interference (EMI) na Radio Frequency Interference (RFI), bishobora gutera urusaku no kubangamira imikorere ya PCBA. Muri urwo rwego, Rich PCBA itanga ingamba zitandukanye:
Imiterere y'ikibaho: Kugira ngo ugabanye ibyago byo guhurirana kw'urusaku, tandukanya imiyoboro ifite umurongo munini n'imiyoboro ifite umurongo muto kandi ushyire ibimenyetso kure y'ingufu n'imiyoboro y'ubutaka. Imiyoboro ifite umurongo igomba kuba ngufi uko bishoboka kose, mu gihe imiyoboro y'amashanyarazi n'imiyoboro y'ubutaka igomba kuba minini uko bishoboka kose kandi igashyirwa mu nzira ifite umwobo muke wo gukurura kugira ngo ugabanye impedance y'umuyoboro w'amashanyarazi.
Ibice byo gushungura: Shyiramo ibice byo kuyungurura nka capacitors na inductors ku ngufu n'imirongo y'ibimenyetso kugira ngo uyungurure urusaku rudakenewe.
Uburyo bwo Gutera no Gukingira: Shyira ibice by'ingenzi mu byuma bya Faraday kugira ngo bizibire EMI na RFI.
Guhitamo ibice: Hitamo ibice by'urubaho rw'amashanyarazi bifite imiterere yo hasi n'uburinzi. Koresha insinga zikingira kugira ngo uhuze urubaho n'ibikoresho byo hanze kugira ngo wirinde ko ibimenyetso bihuzwa.
Ibikoresho bya PCB byo kugenzura imikorere y'inganda
Guhitamo ibikoresho byo gukora PCB ni ingenzi cyane kandi bigomba gushingira ku hantu runaka ho gukorera. Ibikoresho bya PCB bikoreshwa mu nganda bigomba kuba bishobora kwihanganira imimerere mibi, nko ubushyuhe bwinshi, ingufu nyinshi z'amashanyarazi, ubushuhe, kunyeganyega, no guhura n'imiti. Bimwe mu bikoresho bikunze gukoreshwa mu gukora PCB zo mu nganda ni ibi bikurikira:
● Polyimide: Iki gikoresho gifite imikorere myiza gishobora kwihanganira ubushyuhe bukabije kugeza kuri 400°C kandi gikunze gukoreshwa mu bikoresho byo mu kirere, mu gisirikare, no mu nganda zigenzura ubushyuhe bwinshi.
● Ibumba: PCB ya ceramic ikozwe mu gice cy’icyuma cya ceramic n’uduce tw’icyuma. Ifite ubushobozi bwo gutwara ubushyuhe bwinshi kandi ishobora guhangana n’ubushyuhe bwinshi n’ibinyabutabire bikomeye. Ikunze gukoreshwa mu bikoresho by’ikoranabuhanga bikoresha ingufu nyinshi no mu buryo bworoshye.
● PTFE: PTFE cyangwa polytetrafluoroethylene ni fluoropolymer ifite ubushobozi bwiza bwo kwirinda amashanyarazi bushobora kwihanganira ubushyuhe bwinshi kugeza kuri 260°C. Ikunze gukoreshwa mu bikorwa bikoresha ikoranabuhanga rya micro-onde, ndetse no mu bidukikije bikomeye bya shimi.
● FR-4: Iyi mashini ivanze ikoze mu mwenda wa fiberglass iboshye na epoxy resin ni yo ikoreshwa cyane mu bikoresho rusange bya PCB, harimo n'inganda. FR4 PCB ifite ubushobozi bwo gukingira amashanyarazi kandi ishobora kwihanganira ubushyuhe bwinshi n'imiti.
