Kuve nekunzwisisa kwekutanga kweakadhindwa redunhu bhodhi terminology kunogona kuita kushanda nePCB kugadzira kambani nekukurumidza uye nyore. Iyi glossary yedunhu bhodhi mazwi ichakubatsira iwe kunzwisisa mamwe emazwi anonyanya kuzivikanwa muindasitiri. Kunyangwe iyi isiri iyo-inosanganisirwa rondedzero, inzvimbo yakanaka yereferensi yako.
Kuve pane peji rimwe chete nemugadziri wako wekondirakiti (CM) zvakakosha kuti ratidziro chaiyo yechinangwa chako chekugadzira kugadzirwa pasina kutambura kuburikidza zvisina kufanira.quote kunonoka, redesigns uye/kana board respins. Kurongeka mukukurukurirana pakati pevose vane chekuita mukusimudzira bhodhi rako ndicho chinhu chakakosha.
Rondedzero yeYakakosha PCB Dhizaini Terminology
Yakadhindwa Circuit Board Terminology
Mamwe makiyi akadhindwa edunhu bhodhi mazwi anotarisa pakutsanangura chimiro chePCB. Aya mazwi anotsanangurwa zvakare mukugadzira nekugadzira, saka zvakakosha kuti udzidze izvi kutanga.
Layer:Mapuranga ose edunhu anovakwa muzvidimbu, uye zvidimbu zvinotsikirirwa pamwechete kuti zvigadzire astackup. Nheyo imwe neimwe inosanganisira etched mhangura, iyo inoumba ma conductors pamusoro peimwe neimwe.
Kudira mhangura:Nzvimbo dzePCB dzakazadzwa nematunhu makuru emhangura. Matunhu aya anogona kunge aine chimiro chisinganzwisisike.
Mitsetse uye mitsetse yekutumira:Aya mazwi anoshandiswa zvakachinjika, kunyanya kune advanced high speed PCBs.
Signal vs. plane layer:Chiratidzo chechiratidzo chakagadzirirwa kutakura masaini emagetsi chete, asi chinogonawo kuva nemaporigoni emhangura anopa pasi kana simba. Mapande endege anoitirwa kuti ive ndege dzakakwana pasina kana zviratidzo.
Vias:Aya maburi madiki akacherwa muPCB anotendera kuti trace ifambe pakati pematanho maviri.
Zvikamu:Zvinoreva kune chero chikamu chakaiswa paPCB, zvinosanganisira zvakakosha zvinhu senge zvinopikisa, zvinobatanidza, maseketi akasanganiswa, nezvimwe zvakawanda. Zvikamu zvinogona kukwira nekutengeswa kumusoro (SMD components) kana nemitoo inotengeswa mumakomba emhangura (kuburikidza ne-hole components) padare redunhu.
Mapedhi nemakomba:Ose ari maviri aya anoshandiswa kukwirisa zvikamu kubhodhi redunhu uye anoshandiswa senzvimbo yekushandisa solder.
Silkscreen:Aya ndiwo mavara uye marogo akadhindwa pamusoro pePCB. Izvi zvine ruzivo pamusoro pezvinyorwa zvechikamu, marogo ekambani kana nhamba dzechikamu, vagadziri vemareferensi, kana chero rumwe ruzivo rwunodiwa pakugadzira, kugadzira, uye kushandiswa nguva dzose.
Reference vagadziri:Izvi zvinoudza mugadziri uye muunganidzi izvo zvikamu zvinoiswa munzvimbo dzakasiyana pabhodhi redunhu. Chikamu chega chega chine chinongedzo chedhizaini, uye vagadziri ava vanogona kuwanikwa mumafaira ekugadzira mune yako ECAD software.
Soldermask:Iyi ndiyo yepamusoro-yakanyanya layer muPCB inopa bhodhi redunhu ruvara rwayo (kazhinji girini).
