Dukurikije igishushanyo cyumuzunguruko cyateye imbere, kwigana birashobora gukorwa kandi PCB irashobora gukorwa mu kohereza dosiye ya gerber / drill. Ibyo ari byo byose, injeniyeri bakeneye kumva neza uko imizunguruko (n'ibigize hakoreshejwe ibikoresho bya elegitoroniki) bigomba gushyirwaho nuburyo bakora. Kuri injeniyeri ya elegitoroniki, kubona ibikoresho byiza bya software kubishushanyo bya PCB birashobora kuba umurimo utoroshye. Ibikoresho bya software bigenda neza kumushinga umwe wa PCB ntibishobora gukora neza kubandi. Abashakashatsi bifuza ibikoresho byo gushushanya intiti, bikubiyemo ibintu byingirakamaro, bihamye bihagije kugirango bigaruke ibyago, kandi bigire isomero rikomeye bituma bikwira mumishinga myinshi.

Ikibazo cy'ibyuma

Ku mishinga ya IIt, kwishyira hamwe ni ngombwa kugirango imikorere no kwizerwa, no kwinjiza ibikoresho byayobora neza kandi bidayobora muri PCB bisaba abashushanya muri PCB bisaba abashushanya muri PCBS kwigana imikoranire itandukanye. By'umwihariko, nkibice bigize ibice bikomeje kugabanuka, gushyushya amashanyarazi kuri PCB bigenda bikomera. Mugihe kimwe, ibisabwa byimikorere birazamuka. Kugirango ugere kumikorere ishingiye kumikorere, igisubizo cyubushyuhe, imyitwarire yingingo z'amashanyarazi ku kibaho, kandi muri rusange imiyoborere muri ubushyuhe ni ingenzi ku mikorere no kwizerwa kuri sisitemu.

PCB igomba kwigunga kugirango irinde. Imirongo migufi irakundwa nukurinda ibimenyetso byumuringa umuringa byashyizwe mubuyobozi kugirango ukore sisitemu ya elegitoroniki. Ugereranije nubundi buryo buke nka synthetic resin avuza impapuro (srbp, fr-1), cyane cyane ubushobozi bwayo bwo kugumana ubushyuhe burenze ibindi bikoresho. Fr-4 ikoreshwa cyane mumazu maremare yimbitse kimwe nibikoresho byinganda nibikoresho bya gisirikare. Birahuye na ultra-Hejuru Insulation (Ultra-Hejuru Vacuum cyangwa UHV).

Ariko, fr-4 nka PCB yambuyemo imipaka ntarengwa, ituruka ku kuvura imiti ikoreshwa mu musaruro. By'umwihariko, ibikoresho bikunze gushinga aho birimo (bubbles) n'imirongo (igituba kirekire), kimwe no guhindura fibre. Izi sinswa zirashobora gutera imbaraga zidahwitse zidashira kandi zinge pcb wiring imikorere. Ibikoresho bishya byikirahure bikemura ibyo bibazo.

Ibindi bikoresho bikunze gukoreshwa birimo polyimide / fibre yikirahure (bishyigikira ubushyuhe bwo hejuru kandi biragoye) na kapton (byoroshye, bikwiranye nibisabwa nibimenyetso). Ibintu ugomba gusuzuma mugihe uhisemo ibikoresho byubuzima (gusimbuza) birimo guhuza ikirere (cte), ubushyuhe bwinzibacyuho (tg), imikorere yubushyuhe, nubufatanye bwamabuye.

Igisirikare / Aerospace PcBs gisaba ibitekerezo bidasanzwe bishingiye kumiterere yimiterere na 100% byerekana ikizamini (DFT). Mil-STD-883 ishyiraho uburyo nuburyo bukoreshwa bwo kwipimisha ibikoresho bya microelectronic kuri sisitemu ya Aepace, harimo uburyo bwamashanyarazi, hamwe nubugenzuzi no guhugura muri sisitemu muri gahunda. Ibikoresho bitandukanye byibikoresho nkibi.

Usibye kuzuza ibipimo bitandukanye, igishushanyo mbonera cya sisitemu ya elegitoroniki igomba gukurikiza amategeko, nka AEC-Q100 yo gupangura no gupakira ibikoresho byo gupakira imigabane ihuriweho. Ingaruka za CrosStalk zirashobora kubangamira umutekano wimodoka. Kugirango ugabanye izo ngaruka, abashushanya PCB bagomba kwerekana intera hagati yumurongo wibimenyetso n'umurongo w'amashanyarazi. Igishushanyo n mubisanzwe byoroherezwa nibikoresho bya software bihita byerekana ibintu bikeneye kugirango dushyireho imipaka kugirango duhuze imipaka yo guhangana nuburinganire nubugari bwo kwirinda ibikorwa bya sisitemu.

Icyitonderwa:

Kwivanga kuzenguruka ubwabyo ntabwo ari iterabwoba kumenyekana. PCB mumodoka irasakurwa nurusaku, ikorana numubiri muburyo bugoye bwo gutera amakuru udashaka mumuzunguruko. Voltage Spike nihindagurika ryatewe na sisitemu yo gutwika imodoka irashobora gusunika ibice birenze kure yinzobere.

Ikibazo cya software

Ibikoresho bya PCB byuyu munsi bigomba kuba bifite imikorere myinshi yimikorere kugirango byubahirije ibisabwa nabashushanya. Guhitamo ibikoresho byiburyo bigomba kwitabwaho bwa mbere mugushushanya pcb kandi ntugomba na rimwe kwirengagizwa. Ibicuruzwa bivuye kubatoza ibishushanyo, sisitemu ya orcad, na altium biri mubikoresho bya PCB byumunsi.

Inyandiko

Inyandiko ya Altium nimwe mubishushanyo mbonera bya PCB gushushanya kumasoko uyumunsi. Hamwe nimikorere yimodoka yikora, inkunga yumurongo uhinduka hamwe na 3D kwerekana. Igishushanyo mbonera kirimo ibikoresho kumirimo yose yo gushushanya umuzunguruko, uhereye kuri Schematike kuri HDL kimwe na HDL kimwe na Schemit, Isesengura rya PCB, na FPGA REMEDEDE

Abatoza Graphics 'PCB imiterere ya PCB ikemura ibibazo nyamukuru byugarije gahunda yubumenyi bwiki gihe: neza, imikorere - no kongera gutegura igenamigambi ryabajijwe; Kurongora neza mubyifuzo bya topologie; Na electromenical opticication. Ikintu cyingenzi kiranga urufunguzo hamwe nurufunguzo rwibanze rwinganda ni igishushanyo cya sketch, gitanga ibishushanyo mbonera byuzuye muburyo bwikora, bitanga umusaruro umwe nkumwanya muto.

Orcad PCB Muhinduzi

Orcad PCB Muhinduzi ni ibidukikije byateguwe kugirango ushushanye kubishushanyo kurwego urwo arirwo rwose, kuva byoroshye kugeza bigoye. Bitewe no gusuzugura nyayo kuri cadence allegro PCB ibisubizo bya PCB, PCB ishyigikira iterambere rya tekiniki kandi rishobora gucunga inzitizi (Umuvuduko mwinshi, Ubunyangamugayo, nibindi

Dosiye ya gerber

Inganda zitanga inganda za intesiye ya gerber zikoreshwa mugutanga amakuru kumusaruro wa PCB. Mu buryo bwinshi, Gerber asa na PPF muri elegitoroniki; Nuburyo bwa dosiye ntoya yanditse mu rurimi ruvanze. Aya madosiye akorwa na software yumuzunguruko kandi yoherezwa kubakora pcB kuri software ya kamera.

Guhuza neza sisitemu ya elegitoroniki mumodoka hamwe na sisitemu igoye yerekana ibitekerezo byingenzi kubikoresho byombi na software. Abashakashatsi bagamije kugabanya umubare wibishushanyo nigihe cyiterambere, bifite akamaro kanini kubashushanya gushyira mubikorwa.
