Ihinduka rya PCB ryoroshye: Imiterere, Imiterere, na Ubwoko bwa Stackup

Intangiriro:

Inganda zoroshye za PCB zigira uruhare runini mu nganda zikora ibikoresho bya elegitoroniki.Uko ikoranabuhanga rigenda ritera imbere, ibyifuzo bya PCB byoroshye byiyongereye cyane.Muri ubu buyobozi buhebuje, tuzasesengura ubwubatsi bwa PCB bworoshye, imiterere, n'ubwoko bwa stackup.Ni ngombwa kumva ijambo ryibanze rikurikira:Ihinduka rya PCB ryoroshye, Imiterere ya PCB ihindagurika, Ubunini bwumuringa wa PCB bworoshye, Mask ya Solder ya PCB, Imiterere ya PCB, Urupapuro rworoshye rwa PCB, hamwe nubwoko bwa PCB bworoshye kuko ari ngombwa mugutezimbere ibicuruzwa byawe.Ni ngombwa.

1. Ubumenyi bwibanze bwibikorwa bya PCB byoroshye:

A. Ibisobanuro n'ibiranga ikibaho cyoroshye: PCB ihindagurika, izwi kandi nk'umuzunguruko woroshye, ni ikibaho cyumuzingo cyacapwe gishobora kugororwa, kugundwa, cyangwa kugoreka nta kumena.Batanga ibyiza byinshi kurenza PCBs, harimo guhinduka, kuremereye, no kuramba.Iyi mitungo ituma ikwiranye na porogaramu zitandukanye, cyane cyane izisaba ibikoresho bya elegitoroniki byoroheje kandi bigoramye.

B. Imiterere ya PCB ihindagurika: Inzira yo kubaka PCB yoroheje ikubiyemo gukoresha insimburangingo.Inzira zikoreshwa cyane ni polyimide na polyester, zitanga ibikenewe byoroshye guhinduka hamwe nubwishingizi bukenewe kuri PCB zoroshye.Izi substrate zinyura murukurikirane rwintambwe zo gukora nko gutobora, gusasa, no kumurika kugirango habeho icyerekezo cyizunguruka.

C. Sobanukirwa n'ubunini bw'umuringa muri PCB yoroheje: Ubunini bw'umuringa bugira uruhare runini mu mikorere ya PCB yoroheje.Igena ubushobozi bwo gutwara ubu, impedance, hamwe nubworoherane bwa PCB.Guhitamo umuringa utandukanye birashobora gukorwa ukurikije ibisabwa byihariye.Umuringa muremure utanga ubushobozi bwo gutwara ibintu ariko nanone bigabanya guhinduka kwa PCB.Impirimbanyi ikwiye igomba gukubitwa hagati yibi bintu kugirango ugere ku mikorere myiza.

2. Ibice byingenzi bigize PCB yoroheje:

A. Maskike yo kugurisha ya PCB yoroheje: Maskeri yo kugurisha ni urwego rukingira rutwikiriye umuringa wambaye ubusa kuri PCB.Ifasha kwirinda ibiraro byabagurisha, kubora, hamwe namakabutura yamashanyarazi mugihe cyo gusudira.Ihinduka rya PCB rikoresha ibikoresho byabigenewe bidasanzwe kugirango bigaragare ko bihinduka kandi biramba.Guhindura PCB byoroshye kugurisha mask guhitamo no gusaba bisaba gutekereza neza kubishushanyo bya PCB nibisabwa.

B. Imiterere ya PCB ihindagurika: Igishushanyo mbonera, imiterere ya PCB ihindagurika ningirakamaro kubikorwa byiza no kwizerwa.Harimo gushyira ibice, guhuza inzira, hamwe nibimenyetso byerekana ubunyangamugayo.Ibigize bigomba gushyirwa muburyo butuma PCB yunama kandi ikunama uko bikwiye.Inzira zigomba guhindurwa kugirango zigabanye imihangayiko ahantu hagaragara kandi hamenyekane ibimenyetso neza.Uburyo bwiza bwo gushushanya imiterere ya PCB yoroheje harimo gukoresha ibimenyetso bigoramye, kwirinda impande zikarishye, no kwemeza neza neza ibimenyetso.

C. Urupapuro rworoshye rwa PCB: Urupapuro rwometseho rukoreshwa mubikorwa byoroshye bya PCB kugirango uhuze ibice bitandukanye hamwe.Itanga imbaraga za mashini, ituze, hamwe na insulation.Hariho ubwoko butandukanye bwimpapuro zifatika ziraboneka, nkimpapuro zishingiye kuri acrylic, impapuro zishingiye kuri epoxy, nimpapuro zishingiye kuri reberi.Guhitamo impapuro zifatika biterwa nibintu nko kurwanya ubushyuhe, ibisabwa guhinduka, no guhuza nibindi bikoresho.Guhitamo urupapuro rwometseho ni ngombwa cyane kugirango wizere kwizerwa no kuramba kwa PCB yawe yoroheje.

3. Ubwoko bwa PCB bworoshye:

A. Intangiriro kuri PCB stackup: PCB stackup bivuga gahunda yuburyo butandukanye muri PCB.Mubikorwa byoroshye bya PCB, stack up igira uruhare runini mubudakemwa bwibimenyetso, kugenzura inzitizi, no gucunga ubushyuhe.Muguhitamo neza no gutondekanya ibice, abashushanya barashobora guhindura imikorere ya PCBs yoroshye.

B. Ubwoko bwa PCB busanzwe bwa PCB: Hariho ubwoko butandukanye bwimiterere ikoreshwa mubikorwa byoroshye bya PCB, harimo urwego rumwe, ibice bibiri, hamwe nuburyo bwinshi.Buri bwoko bwa stacking bufite ibyiza byabwo kandi bigarukira.PCBs imwe-yoroheje PCBs nuburyo bworoshye kandi buhendutse cyane, ariko bufite ubushobozi buke bwo kuyobora.Double-layer flexible PCB itanga amahitamo menshi kandi irashobora kwakira ibishushanyo mbonera.PCBs nyinshi zihindagurika zitanga uburyo bworoshye bwo guhinduka, hamwe no kugenzura inzitizi, kandi birashobora gushyigikira ubucucike buri hejuru.Ariko, biraruhije kandi birahenze kubikora.

Muri make:

Muri iki gitabo cyuzuye, turareba ibintu byose byerekeranye no gukora PCB byoroshye, harimo ubwubatsi, imiterere, mask yo kugurisha, impapuro zifatika, nubwoko bwa stackup.Gusobanukirwa ibi bintu byingenzi bizafasha abashushanya guhindura imikorere no kwizerwa byimiterere ya PCB yoroheje.Inzira n'ikoranabuhanga ni ingenzi cyane mu gukora PCB zoroshye, kandi mugukurikiza imikorere myiza, abayikora barashobora kwemeza itangwa ryibicuruzwa byujuje ubuziranenge, byizewe kugirango bikemure inganda za elegitoroniki.
