Mune zvemagetsi, iyo yakadhindwa yedunhu bhodhi (PCB) ndiyo musana wezvizhinji zvemagetsi zvigadzirwa.Nepo kugadzirwa kwePCB dzepamberi kuchiwanzoitwa nenyanzvi, kugadzira maPCB ane mativi maviri kumba kunogona kuve sarudzo inodhura uye inoshanda mune dzimwe nguva.Mune ino blog, isu tichakurukura nhanho-ne-nhanho maitiro ekugadzira kaviri-mativi PCB mukunyaradza kweimba yako wega.
1. Unganidza zvinhu zvinodiwa:
Usati wanyura mukugadzira nzira, zvakakosha kuunganidza zvese zvinodiwa.Izvi zvinosanganisira macopper-clad laminates, zvicherechedzo zvechigarire, laser printers, ferric chloride, acetone, drill bits, copper-plated wire, uye midziyo yekuchengetedza yakaita segirovhosi nemagogi.
2. Gadzira chimiro chePCB:
Uchishandisa PCB dhizaini software, gadzira schematic yedunhu remagetsi raunoda kuvaka.Mushure mekunge schematic yapera, gadzira iyo PCB dhizaini, uchiisa akasiyana zvikamu uye zviteshi sezvinodiwa.Ita shuwa kuti marongerwo akakodzera maviri-mativi PCB.
3. Dhinda chimiro chePCB:
Dhinda chimiro chePCB pabepa rinopenya uchishandisa printa yelaser.Ita shuwa yekumisikidza mufananidzo wacho wakatwasuka kuti uenderere nemazvo kune copper clad board.
4. Magadzirirwo ekufambisa:
Cheka iyo yakadhindwa marongero woiisa yakatarisa pasi pabhodhi rakapfeka mhangura.Zvichengetedze panzvimbo ne tepi uye zvipise nesimbi pamusoro pekupisa kukuru.Dzvanya zvakasimba kwemaminetsi gumi kuti uve nechokwadi chekugovera kupisa.Izvi zvichaendesa inki kubva papepa kuenda kune ndiro yemhangura.
5. Etching ndiro:
Nyatsobvisa pepa kubva pabhodhi rakapfeka mhangura.Iwe zvino uchaona iyo PCB dhizaini ichiendeswa kunzvimbo yemhangura.Dururira ferric chloride yakakwana mupurasitiki kana mudziyo wegirazi.Nyura bhodhi mune ferric chloride mhinduro, kuve nechokwadi kuti yakavharwa zvachose.Gadzirisa zvinyoro mhinduro kuti ikurumidze kuita etching.Rangarira kupfeka magirovhosi nemagirazi panguva iyi.
6. Chenesa uye ongorora bhodhi redunhu:
Mushure mokunge maitiro etching apera, bhodhi rinobviswa kubva pane mhinduro uye rinoshambidzwa nemvura inotonhora.Cheka mipendero uye zvinyoro geza bhodhi nesiponji kuti ubvise inki yakawandisa uye zvisaririra.Pukuta bhodhi zvachose uye tarisa chero kukanganisa kunogona kuitika kana matambudziko.
7. Kuchera:
Uchishandisa chibooreso chine chidiki diki, nyatso chera makomba paPCB panzvimbo dzakatarwa dzekuisa chikamu uye solder.Ita shuwa kuti gomba rakachena uye harina chero tsvina yemhangura.
8. Welding components:
Isa zvinhu zvemagetsi kumativi ose ePCB uye uzvichengetedze nezvikamu.Shandisa simbi yesimbi uye solder wire kuti ubatanidze zvikamu kune zvinyorwa zvemhangura.Tora nguva yako uye ita shuwa kuti majoini e solder akachena uye akasimba.
mukupedzisa:
Nekutevera iyi nhanho-ne-nhanho mirairo, unogona kubudirira kugadzira kaviri-mativi PCB kumba.Nepo maitiro acho anogona kutanga anosanganisira kumwe kuedza uye kukanganisa, nekudzidzira uye kutarisa kune zvakadzama, unogona kuwana hunyanzvi mhedzisiro.Rangarira kugara uchiisa kuchengeteka pakutanga, pfeka giya rekudzivirira rakakodzera uye shanda munzvimbo ine mhepo inofefetera.Saka sunungura hunyanzvi hwako uye tanga kuvaka ako ega maviri-mativi maPCB!
