Nzira yekuwana sei gomba rebofu muPCB board?Mumunda wekugadzirwa kwemagetsi, PCB (Printed Circuit Board, yakadhindwa redunhu bhodhi) inoita basa rinokosha, inobatanidza uye inotsigira zvakasiyana-siyana zvemagetsi, kuitira kuti zvigadzirwa zvemagetsi zvishande zvakanaka.Mabofu maburi chinhu chakajairika dhizaini muPCB kugadzira kubatanidza maseketi pamatanho akasiyana, asi anowanzo kunetsa kuwana uye kutarisa.Ichi chinyorwa chichatsanangura nzira yekunyatsowana mapofu maburi muPCB mabhodhi kuve nechokwadi chemhando uye kuvimbika kwebhodhi.
1. Shandisa nzira dzekuongorora dzemaziso
Nzira yekuwana sei gomba rebofu muPCB board?Optical inspection inzira yakajairika inoshandiswa kutsvaga mapofu maburi mumabhodhi ePCB.Nekushandisa maikorosikopu yakakwirira-resolution, nyanzvi dzinogona kutarisisa paPCB pamusoro pamakomba anogona kuitika.Kuti uwedzere kucherechedzwa, chitubu chechiedza chakakosha, sechiedza cheultraviolet, chinogona kushandiswa kubatsira kuziva nzvimbo yegomba rebofu.
Pamusoro pezvo, mamicroscopes edhijitari uye makamera akakwira-resolution anogona kushandiswa kuchengetedza zvakacherechedzwa mumhando yedhijitari yekuongorora nekurekodha kunotevera.Iyi nzira inokodzera kugadzirwa kwebatch diki uye kutsvagisa nekusimudzira nhanho, asi inogona kuve inopedza nguva uye inorema mukugadzirwa kwakakura.
2. Shandisa X-ray yekuona
X-ray kuongorora inzira ine simba kwazvo inogona kushandiswa kutsvaga mapofu akavigwa makomba mumabhodhi ePCB.Inoona nzvimbo yegomba rebofu nekuvhenekera bhodhi rePCB uye kutora mufananidzo unoratidzwa weX-ray.Nekuda kwekupinda kweX-ray, zvinokwanisika kuona makomba akadzika pane kungoona pamusoro.
X-ray yekuongorora ine hunhu hwakanyanya uye yakakodzera kune yakakura-yakakura kugadzirwa nharaunda.Nekudaro, zvinoda midziyo uye kudzidziswa kwevashandi vane ruzivo, saka panogona kunge paine zvimwe zvisingakwanisi maererano nemutengo uye zvehunyanzvi zvinodiwa.
3. Shandisa tekinoroji yekuona kupisa
Tekinoroji yekuona tekinoroji inzira yekushandisa ma detectors ekupisa kutsvaga mapofu akavigwa maburi mumabhodhi ePCB.Nenzira iyi, kuvepo kwekupisa kwemapofu kunogona kuonekwa nekuisa chitubu chekupisa kune rumwe rutivi rwePCB board uye kutarisa kuchinja kwekushisa kune rumwe rutivi.Nekuti kuvigwa kwemapofu kunokanganisa kuitisa kupisa, vanoratidza mhinduro dzakasiyana dzekushisa panguva yekuona.
Nzira yekuwana sei gomba rebofu muPCB board?Kusarudza nzira yakakodzera zvinoenderana nehukuru hwekugadzira, bhajeti uye tekinoroji zvinodiwa.Hazvina mhosva kuti ndeipi nzira inoshandiswa, inofanirwa kuve nechokwadi chemhando uye kuvimbika kwePCB board kuti isangane nezvinodiwa zvemidziyo yemagetsi.Mune PCB yekugadzira maitiro, kutsvaga kunoshanda kwemaburi mapofu kwakakosha kuve nechokwadi chemhando uye kuvimbika kwebhodhi redunhu.
