Ni ubuhe bwoko butandukanye bwa PCB?
Ibikoresho bya PCB biri mu buryo butandukanye bwo gukoresha mu buryo butandukanye. Guhitamo imiterere ikwiye y'igicuruzwa bizasaba injeniyeri gusuzuma uburyo igikoresho gikoreshwa, ingano yacyo n'ubushobozi bwacyo. Suzuma ibi bikurikira kugira ngo usobanukirwe ubwoko bw'amabara y'urukiramende yacapwe n'ubwoko bukwiriye ibikorwa byawe:
PCB zo ku ruhande rumwe: Gukora PCB bikubiyemo gukora uruziga rw'amashanyarazi mu urwego rumwe rw'icyuma n'urwego rworoshye rw'icyuma. Ibice byose bishongeshejwe ku ruhande rumwe.
PCB zifite impande ebyiri: Ubwoko bwa PCB aho impapuro z'icyuma zikoreshwa mu gukwirakwiza amazi zishyirwa ku mpande zombi z'icyuma gifunga amazi.
Umwobo ushobora gucukurwa hagati mu gice cy'urubaho kugira ngo imiyoboro ishobore kwinjira ku mpande zombi.
PCB nyinshi: Nibura PCB eshatu zifite amashami abiri zifatanye hejuru y’izindi zifite amashami menshi yo gukingira kugira ngo zigabanye ubushyuhe. Kole zihariye zifata neza zituma PCB ziguma hamwe.
PCB zoroshye: Ibibaho byacapwe bigaragaza substrates zoroshye kugira ngo bifashe injeniyeri kwimenyereza imiterere y'ibicuruzwa bito. Ikoranabuhanga rishobora kubaho mu buryo bw'ubwubatsi bw'uruhande rumwe, ubw'uruhande rubiri cyangwa ubw'urwego rwinshi.
PCB zikomeye: Ni ingirakamaro ku bicuruzwa bikoresha bigumana imiterere imwe mu gihe cyose cy'ubuzima bwabyo. PCB zikomeye zikorwa hakoreshejwe substrates zikomeye zirinda kuzunguruka.
PCB zikora neza: Ibibaho byacapwe bya circuit bikoresha ibikoresho bikomeye n'ibyoroshye. Ibi bigena imiterere yemerera abakora ibicuruzwa kuzigama umwanya, kuko uburyo bwo guhuza bushobora gushyirwa kuri circuit imwe.
PCB zishyigikiwe na aluminiyumu: Ubwoko bwa PCB busimbura substrate ya aluminiyumu aho fiberglass yaba iri. Yagenewe gukoreshwa n'ibikoresho by'ikoranabuhanga bya PCB bikomeye cyane nk'amatara ya LED.
PCB zifite umurongo wo hejuru: Urubuga rw'itumanaho rwakozwe kugira ngo rwohereze ibimenyetso bikomeye nka 2 GHz.
PCB zikorwa n'iki?
Uburyo bwo gukora PCB buratandukanye bitewe n'icyo igikoresho cyagenewe ndetse n'ingufu zikenewe kugira ngo igikoresho cy'ikoranabuhanga gikore neza. Mbere yo guhitamo ibikoresho byo guteranya urubuga rw'amashanyarazi, ni byiza kumenyera ibice bine by'ingenzi bya PCB:
Substrate: Imiterere y'urubaho rwa circuit — ibice byose bifatanye kuri ubu buso.
Laminate: Ibikoresho bifatanya urwego rwose rwa PCB.
Agapfukamunwa ko gusoda: Kera hejuru y'udupfukamunwa tw'umuringa kugira ngo gashobore kwitandukanya kandi gakingira imiyoboro y'ibintu bikomoka ku bidukikije.
Silkscreen: Ifata ku gipfukamunwa cya solder kugira ngo ibice byacyo bishobore gushyirwaho ikimenyetso.
Igishushanyo mbonera ni iki?
Ishusho y'icyitegererezo, cyangwa imbonerahamwe, ni ishusho y'ibintu bigize sisitemu ikoresha ibimenyetso bifatika, aho gukoresha amashusho nyayo.
Ni ibihe bitangwa kuri serivisi ya PCB Layout?
Ku mabwiriza ya serivisi ya PCB Layout, amakuru akurikira azatangwa muri dosiye y'ibisohoka:
Amakuru yose ya Gerber arimo dosiye za Drill (Imiterere y'uruziga, Imiterere ya Mask, Imiterere ya Silk, Imiterere, Imiterere ya Drill, Imiterere ya Paste)
Amakuru yo Guhitamo no Gushyira Aho Uherereye
Dosiye y'Umushinga w'Inyandiko y'Ibintu ya nyuma
Urutonde rw'umushinga na dosiye ya PDF
Ni ubuhe bwoko bw'ibikoresho bikunze gukoreshwa mu gukora PCB zikomeye?
Ibikoresho bya FR4
Ibikoresho by'umuvuduko wo hejuru
Substrate ya FR4 yihuta cyane ifite DF 1Ghz.
Substrate ya FR4 yihuta cyane ifite Df 10Ghz
Ibikoresho bya ceramic bifite flue nkeya, imikorere yabyo iri kuri 10Ghz
Ibikoresho bya PTFE cyangwa ibikoresho bya PTFE byiyongereyeho imbaraga
Ibikoresho bya PTFE bishyushye cyane
Ni ubuhe bwoko bw'ubuhanga bwo gukora bukoreshwa mu gukora PCB zikomeye?
Hari uburyo bwinshi bwo gukora bukoreshwa mu gukora PCB zikomeye. Intambwe zikurikira zikubiye mu buhanga bwinshi.

Bitwara igihe kingana iki kugira ngo PCB ikoreshwe neza?
Ibikurikira bivuga ku gihe gikenewe kugira ngo hakorwe PCB zikomeye muri Richfulljoy.
Bifata iminsi 1-5 kugira ngo PCB zihinduke vuba.
Hafatwa icyumweru 1-2 kugira ngo hakorwe icyitegererezo n'urutonde ruto rwa PCB zikomeye.
Ibyumweru 2-4 bimara mu gukora PCB zikomeye.
Itandukaniro nyamukuru ni irihe: PCB ikomeye vs PCB ihindagurika?
Itandukaniro nyamukuru riri hagati y'ikibaho gikomeye cya PCB n'ikibaho gihindagurika cya PCB ni:
1), Bikorwa hakoreshejwe ibikoresho bitandukanye: ibyuma biramba bikozwe na FR4, ceramic, metal core, PTFE nibindi, byose ni biramba (ntibishobora gupfunyika), mu gihe PCB yoroshye ikorwa na polyimide (PI), PET, Kapton matrial ishobora gupfunyika incuro ibihumbi;
2), Niba zishobora gupfunyika cyangwa zitapfunyika: PCB ikomeye ntabwo ishobora gupfunyika, ariko PCB yoroshye ishobora gupfunyika;
3), Zikoresha uburyo butandukanye: ibyuma biramba bikoreshwa mu bikoresho by'ikoranabuhanga bidahinduka, ariko ibyuma biramba biramba bikoreshwa mu bikoresho bihora bigenda, nka kamera, mudasobwa zigendanwa, telefoni zigendanwa, ibikoresho byimuka n'ibindi.
Gukora PCB ikomeye bisaba angahe?
