Imwe yemaphutha akajairika akaitwa panguva PCB kugadzira ndiko kurongeka kwakasarudzika, izvo zvinogona kukonzera maitiro ese kutadza. Iyo PCB gungano maitiro anogona kushanda kubva kune yemagetsi kuenderera nzvimbo yekutarisa, kunyangwe kuburikidza nemagetsi kuongorora. Mukugadzirwa, kurongeka kwendege uye netsiva yechiratidzo uye nhambwe iri pakati pezvikamu zviri pedyo zvakakosha.

Kuti uve nechokwadi chekuti ruzivo rwekugadzira runodikanwa kuti riongorore kutarisisa kwekugadzirisa, vashandi vePCB vanofanirwa kugadzira hunhu hwakakodzera hwemhangura mune data rekugadzira, ndokuti, kuti uwane kurongeka kwakakodzera. Izvi zvemhangura maficha anopa nzira yekuongorora zvekupedzisira zvinhu, kana mukati meQ & A macheki aitwa, ayo anonatswa kusvika kunzvimbo yekugadzira.

Rakagamuchirwa?

Chekutanga basa remhangura rakawedzerwa kune yega yega dura ndeyekuona iyo dura redhiyo inoenderana nemamwe ese mamwe matanda. Nhengo yega yega inogamuchira nhamba yakaturikidzana yakanamirwa yakananga mumhangura, iyo inoratidza chinzvimbo chayo mune iyo cascade, uye iyo nhamba yenhamba inofanira kuverengerwa mukati medunhu replate rapera. Mitsara inofanirwa kuve iri padyo nemucheto webhodhi kuti isakanganisa magetsi emagetsi edunhu. Inogona kutora fomu yenhamba imwe pane yega yega. Asi nhamba dzinogona kunge dzisingakwirirane. Kana machati macheki ese akarongedzwa, anofanirwa kunge achinyatso kuoneka kana achionekwa kubva kumusoro kumusoro.

Zvidimbu zvinowanzoiswa mumabhokisi emakona emakona kuti zvive nyore kuzivikanwa. Bvisa iyo yekumisikidza mask uye skrini basa kubva munzvimbo yakatenderedza materu kuti zvive nyore kutarisa matanda kuburikidza nePCB yakazara kuburikidza neyekuongorora mwenje sosi yakaiswa kuseri kwegungano. Mitsara haigone kuunganidzwa kune chero denderedzwa pane basa remhangura, senge riya remagetsi kana polygon.

Pcb stacks emhangura maficha ari kumucheto kwePCB kuti aone kutariswa kwekutarisa kwematanho ehurongwa. Kana iyo pcb ikadzingwa kubva panhare, iyo geometry inofanirwa kuwedzera kunze kwekumucheto kwebhodhi kuti ifumure mhangura. Iyo yakakodzera lamination geometry inogona kuoneka nekucherechedza iyo yakarongedzwa mitsetse kumucheto kwemapfumo akapedzwa.

Chinangwa cheyedzo yekuyedza ndechekusimbisa iyo yakamiswa-yakachekwa mhangura ukobvu uye upamhi pane yega yega dura mune iyo lamination. Iyo yekuyedza trace ichave 50mil pakureba uye 5mil muukobvu, uye inofanirwa kuwedzera kupfuura kumucheto kwebhodhi kuitira kuti mhangura ifumurwe apo iyo PCB inotamiswa kubva panhivi. Iko kumucheto kwekutarisa kwekuyedza kunogona kuyerwa neyekuongorora microscope. Iri basa rakakosha mukugadzira neimedance inotyairwa geometry.
