PCB ipfupiso yaungasangana nayo paunenge uchikurukura zvemagetsi kana mabhodhi edunhu.Asi, wakambozvibvunza here kuti izere fomu rePCB chii?Mubhuku rino, tinovavarira kunzwisisa zviri nani kuti acronym iyi inomirirei uye zvazvinoreva munyika yemagetsi.
Chii chinonzi Printed Circuit Board?
PCB inomirira "Printed Circuit Board".Mukutaura kwakapfava, PCB ibhodhi redunhu rakagadzirwa neasina-conductive zvinhu ane conductive makwara akaiswa mairi.Idzi nzira dzinogadzira hukama pakati pezvikamu zvemagetsi zvakasiyana uye inobvumira bhodhi kuti rishande sedunhu rakazara.MaPCB anoshandiswa mumhando dzakasiyana-siyana dzemidziyo yemagetsi, kubva kumatoyi akareruka uye midziyo yemagetsi kuenda kumidziyo yekurapa yepamusoro nemakomputa.
Zvakanakira zvePCB
MaPCB anopa mabhenefiti akati wandei pane nzira dzekare dzekubatanidza zvinhu zvemagetsi.Chekutanga, idiki diki, zvichiita kuti ive yakanaka kune madiki emagetsi.Nekuda kwehukuru hwawo, maPCB zvakare akareruka uye anotakurika kupfuura echinyakare nzira dzewaya.Chechipiri, sezvo nzira dzekufambisa dzakaiswa mubhodhi, njodzi yekukuvara kana kubviswa yakaderedzwa zvakanyanya.Izvi zvinoita kuti maPCB avimbike kupfuura dzimwe sarudzo.
Mhando dzePCBs
Kune marudzi akawanda ePCB anowanikwa, imwe neimwe iine chinangwa chayo.Heano mamwe emhando dzakajairika:
1. Single-sided PCB ndiyo inonyanya kukosha mhando, nzira dzese dzekufambisa dziri kune rumwe rutivi rwebhodhi.Izvi zvinowanzo shandiswa mumaseketi akareruka, kusanganisira matoyi uye midziyo iri nyore.
2. Maviri-mativi PCB ane conductive nzira kumativi ose ebhodhi, achibvumira mamwe masekete akaoma.Zvisinei, vachiri nyore zvichienzaniswa nedzimwe sarudzo.
3. Multilayer PCBs ine akati wandei akaturikidzana emaitiro ekuitisa, achibvumira mamwe masekete akaomarara.Izvi zvinowanzo shandiswa mumidziyo yemagetsi yepamusoro semakomputa uye mafoni.
4. Rigid-Flex PCBs isarudzo itsva iyo inosanganisa zvakanakira yakasimba uye inoshanduka PCBs.Iwo akanakira kushandiswa mumidziyo inoda kuve yakasimba asi ichichinjika, senge midziyo yekurapa.
mukupedzisa
Pakazara, PCB chinhu chakakosha munyika yemagetsi, inopa yakavimbika uye inoshanda nzira yekubatanidza zvinhu zvemagetsi.Ivo vanopa akawanda mabhenefiti pamusoro pechinyakare wiring nzira, kusanganisira diki saizi, kureruka uremu, uye yakakwirira kuvimbika.Kuziva chimiro chakazara chePCB nemhando dzakasiyana dziripo zvinogona kukubatsira kunzwisisa zvirinani basa rinoitwa nezvikamu izvi mumudziyo wemagetsi.
