Mabhodhi ePCB edunhu anoshandiswa zvakanyanya muzvigadzirwa zvemagetsi zvakasiyana-siyana munyika yanhasi yakasimukira.Zvinoenderana nemaindasitiri akasiyana, ruvara, chimiro, saizi, layer, uye zvinhu zvePCB redunhu mabhodhi zvakasiyana.Nokudaro, ruzivo rwakajeka runodiwa mukugadzirwa kwePCB circuit board, kana zvisina kudaro kusanzwisisana kunowanzoitika.Ichi chinyorwa chinopfupikisa gumi repamusoro zvikanganiso zvichibva pamatambudziko ari mukugadzira maitiro ePCB edunhu mabhodhi.
1. Tsanangudzo yezinga rekugadzirisa haisi pachena
Iyo single-sided board yakagadzirirwa pane TOP layer.Kana pasina rairo yekuzviita pamberi uye kumashure, zvingave zvakaoma kutengesa bhodhi nemidziyo pairi.
2. Chinhambwe chiri pakati penzvimbo yakakura foil yemhangura uye furemu yekunze iri padyo zvakanyanya
Chinhambwe chiri pakati penzvimbo yakakura yemhangura foil uye yekunze furemu inofanirwa kunge inosvika 0.2mm, nekuti kana ichikuya chimiro, kana yakagayiwa pafoiri yemhangura, zviri nyore kuita kuti foil yemhangura iwedzere uye ikonzere kuti solder irambe. kudonha.
3. Shandisa zvivharo zvekuzadza kudhirowa mapedhi
Kudhirowa mapadhi ane mafiller blocks anogona kupfuura iyo DRC yekuongorora kana kugadzira maseketi, asi kwete ekugadzirisa.Naizvozvo, mapedhi akadaro haakwanise kugadzira zvakananga solder mask data.Kana solder resist ikashandiswa, nzvimbo ye filler block ichavharwa ne solder resist, zvichiita kuti mudziyo Welding yakaoma.
4. Iyo yegetsi yepasi pasi ndeye flower pad uye kubatana
Nemhaka yekuti yakagadzirwa semagetsi emagetsi mumhando yemapadhi, pasi pevhu rinopesana nemufananidzo pabhodhi rakadhindwa, uye zvose zvinobatanidza mitsara yega.Chenjerera paunenge uchidhirowa seti dzinoverengeka dzemagetsi emagetsi kana akati wandei ega ega mitsara, uye usasiye mapundu kuita mapoka maviri Dunhu diki remagetsi harigone kuita kuti nzvimbo yekubatanidza ivharwe.
5. Vatambi vakarasika
Iwo maSMD pads emhando yekuvhara mapedhi anounza kusagadzikana ku-on-off bvunzo yebhodhi rakadhindwa uye chikamu welding.Kana iyo dhizaini iri diki zvakanyanya, ichaita kuti kudhinda kwescreen kuome, uye kana yakakura, mavara anopindirana, zvichiita kuti zviome kusiyanisa.
6.surface gomo mudziyo Mapedhi mapfupi
Izvi ndezvekuedza-off.Kune yakanyanya kuomesesa pamusoro pemidziyo yekumisikidza, chinhambwe pakati pemapini maviri idiki, uye mapadhi zvakare akatetepa.Kana uchiisa mapini ebvunzo, anofanirwa kudzedzereka kumusoro nekudzika.Kana iyo padhi dhizaini yakanyanya kupfupika, kunyangwe isiri iyo Ichakanganisa kuisirwa kwechigadzirwa, asi ichaita kuti mapini ekuedzwa asaparadzaniswe.
7. Single-side pad aperture setting
Mapedhi ane divi rimwe chete haawanzo dhiriwa.Kana maburi akaboorwa achida kuiswa chiratidzo, aperture inofanira kugadzirwa sezero.Kana kukosha kwakagadzirwa, ipapo kana data yekuchera inogadzirwa, gomba rinoronga richaonekwa panzvimbo iyi, uye matambudziko achamuka.Mapadhi ane divi rimwe chete semaburi akaboorwa anofanira kunyatsomakwa.
8. Pedhi inopindirana
Panguva yekuchera, chibooreso chinoputswa nekuda kwekuchera kwakawanda munzvimbo imwechete, zvichikonzera kukuvara kwegomba.Iwo maburi maviri ari mu-multi-layer board anopindirana, uye mushure mekunge iyo yakaipa yadhirowa, inozoonekwa sendiro yekuzviparadzanisa, zvichikonzera zvimedu.
9. Kune akawanda mabhuroki ekuzadza mukugadzira kana mabhuroki ekuzadza anozadzwa nemitsara yakaonda kwazvo
Iyo data yefotoplotting yakarasika, uye iyo photoplotting data haina kukwana.Nekuti chivharo chekuzadza chinodhonzwa chimwe nechimwe muchiedza chekudhirowa dhizaini, saka huwandu hwemwenje yekudhirowa data inogadzirwa yakakura kwazvo, izvo zvinowedzera kuoma kwekugadzirisa data.
10. Graphic layer abuse
Kumwe kubatanidzwa kusingabatsiri kwakaitwa pane mamwe magiraidhi layer.Yakanga iri bhodhi ine mana-layer asi anopfuura mashanu akaturikidzana ematunhu akagadzirwa, izvo zvakakonzera kusanzwisisana.Kutyorwa kwemaitiro akajairika.Iyo giraidhi layer inofanirwa kuchengetedzwa yakasimba uye yakajeka paunenge uchigadzira.
