Imyobo iriPCBBirashobora gushyirwa mubice byacishijwe mu mwobo (PTH) kandi bidashyizwe mu mwobo (NPTH) ukurikije niba bifite amashanyarazi.
Bishyizwe mu mwobo (PTH) bivuga umwobo ufite icyuma gitwikiriye urukuta rwawo, rushobora kugera ku mashanyarazi hagati yimiterere yimyitwarire kumurongo wimbere, kumurongo winyuma, cyangwa PCB zombi.Ingano yacyo igenwa nubunini bwumwobo wacukuwe hamwe nubunini bwurwego rushyizweho.
Kudashyirwa mu mwobo (NPTH) ni ibyobo bititabira guhuza amashanyarazi ya PCB, bizwi kandi nk'ibyuma bidafite ibyuma.Ukurikije urwego umwobo winjira muri PCB, umwobo urashobora gushyirwa mubice nko mu mwobo, ugashyingurwa binyuze / umwobo, nimpumyi ukoresheje / umwobo.
Binyuze mu mwobo byinjira muri PCB yose kandi birashobora gukoreshwa muburyo bwimbere hamwe / cyangwa guhagarara no gushiraho ibice.Muri byo, umwobo ukoreshwa mugukosora no / cyangwa guhuza amashanyarazi hamwe nibice bigize (harimo pin na insinga) kuri PCB byitwa ibyobo.Bishyizwe mu mwobo ukoreshwa muburyo bwimbere uhuza ariko udashizeho ibice biganisha cyangwa ibindi bikoresho byongera imbaraga byitwa binyuze mumyobo.Hariho intego ebyiri zo gucukura binyuze mu mwobo kuri PCB: imwe ni ugukora gufungura binyuze mu kibaho, kwemerera inzira zikurikiraho gukora imiyoboro y'amashanyarazi hagati y'urwego rwo hejuru, igorofa yo hasi, hamwe n'inzira y'imbere y'ubuyobozi;ikindi ni ugukomeza uburinganire bwimiterere nuburyo bugaragara bwo kwishyiriraho ibice.
Viyasi zimpumyi hamwe na vias zashyinguwe zikoreshwa cyane mubuhanga buhanitse cyane (HDI) tekinoroji ya HDI pcb, cyane cyane murwego rwo hejuru rwa pcb.Impumyi zihumye mubisanzwe zihuza urwego rwa mbere kurwego rwa kabiri.Mubishushanyo bimwe, vias ihumye irashobora kandi guhuza urwego rwa mbere kurwego rwa gatatu.Muguhuza vias zihumye kandi zishyinguwe, guhuza byinshi hamwe nubucucike bwumuzunguruko mwinshi bisabwa HDI birashobora kugerwaho.Ibi bituma ubwiyongere bwububiko bwibikoresho bito mugihe utezimbere amashanyarazi.Viyasi ihishe ifasha kugumisha imbaho zumuzingi zoroheje kandi zoroshye.Impumyi kandi ishyingurwa hakoreshejwe ibishushanyo bisanzwe bikoreshwa muburyo bugoye-bushushanyije, uburemere-bworoshye, nibicuruzwa bya elegitoronike bihenze nkaamaterefone, ibinini, naibikoresho by'ubuvuzi.
Impumyizakozwe mugucunga ubujyakuzimu bwo gucukura cyangwa gukuraho laser.Iheruka nuburyo busanzwe.Gutondekanya binyuze mu mwobo bikorwa binyuze muburyo bukurikiranye.Ibisubizo bivuye mu mwobo birashobora gutondekwa cyangwa gutigita, ukongeraho intambwe yo gukora no kugerageza intambwe no kongera ibiciro.
Ukurikije intego n'imikorere y'imyobo, birashobora gushyirwa mubikorwa nka:
Binyuze mu mwobo:
Nibyobo byuma byifashishwa kugirango bigere kumashanyarazi hagati yuburyo butandukanye bwo kuyobora kuri PCB, ariko ntabwo bigamije gushiraho ibice.
PS.
Ibyobo bigize:
Zikoreshwa mugurisha no gutunganya plug-in ibikoresho bya elegitoroniki, kimwe no mu mwobo ukoreshwa mu guhuza amashanyarazi hagati yuburyo butandukanye.Ibyobo bigize ibice bisanzwe mubyuma, kandi birashobora no kuba nkibintu byinjira kubihuza.
Gutera umwobo:
Nibinini binini kuri PCB bikoreshwa mukurinda PCB kumurongo cyangwa izindi nzego zifasha.
Umwobo:
Byakozwe haba muburyo bwo guhuriza hamwe imyobo myinshi cyangwa gusya ibishishwa muri gahunda yo gucukura imashini.Mubisanzwe bikoreshwa nkibikoresho byo gushiraho pin ihuza, nka ova imeze nka ova imeze nka sock.
Umwobo winyuma:
Nibyobo byimbitse byacukuwe mubyobo byacometse kuri PCB kugirango bitandukane kandi bigabanye ibimenyetso byerekana mugihe cyoherejwe.
Ibikurikira nibyobo bifasha abakora PCB bashobora gukoresha muriUburyo bwo gukora PCBko abashakashatsi ba PCB bagomba kuba bamenyereye:
Kubona ibyobo ni bitatu cyangwa bine hejuru no hepfo ya PCB.Ibindi byobo biri ku kibaho bihujwe nibi byobo nkibisobanuro byerekana umwanya wo gushiraho no gukosora.Bizwi kandi nk'imyobo cyangwa intego yibirindiro, bikozwe hamwe na mashini yintego (optique yo gukubita imashini cyangwa imashini yo gucukura X-RAY, nibindi) mbere yo gucukura, kandi ikoreshwa mugushira no gutunganya pin.
●Guhuza imbereibyobo ni ibyobo bimwe kuruhande rwikibaho kinini, bikoreshwa mugushakisha niba hari gutandukana mubibaho byinshi mbere yo gucukura mubishushanyo mbonera.Ibi byerekana niba gahunda yo gucukura igomba guhinduka.
● Imyobo ya code ni umurongo wibyobo bito kuruhande rumwe rwo hepfo yubuyobozi bikoreshwa mukugaragaza amakuru yumusaruro, nkicyitegererezo cyibicuruzwa, imashini itunganya, code ya operateri, nibindi. Muri iki gihe, inganda nyinshi zikoresha ibimenyetso bya laser aho.
Ho Umwobo wa Fiducial ni umwobo ufite ubunini butandukanye kuruhande rwikibaho, bikoreshwa mukumenya niba diameter yimyitozo ikwiye mugihe cyo gucukura.Muri iki gihe, inganda nyinshi zikoresha ubundi buryo bwikoranabuhanga kubwiyi ntego.
T Ibice byacitse ni ugushiraho umwobo ukoreshwa mugukata PCB no gusesengura kugirango ugaragaze ubwiza bwibyobo.
Ibizamini bya Impedance ni ibyobo byapimwe bikoreshwa mugupima inzitizi ya PCB.
Oles Ibyobo byateganijwe mubisanzwe ni ibyobo bidafite isahani bikoreshwa kugirango birinde ikibaho guhagarara inyuma, kandi akenshi bikoreshwa muguhagarara mugihe cyo kubumba cyangwa gufata amashusho.
Umwobo wibikoresho muri rusange ni umwobo udafite isahani ikoreshwa mubikorwa bifitanye isano.
Ove Imyobo ya Rivet ni umwobo udafite isahani ikoreshwa mugukosora imirongo hagati ya buri gice cyibikoresho byingenzi hamwe nimpapuro zihuza mugihe cyo kumanika imbaho nyinshi.Umwanya wa rivet ugomba gucukurwa mugihe cyo gucukura kugirango wirinde ibibyimba kuguma kuri uwo mwanya, bishobora gutera imbaho kumeneka nyuma.
