Mabhodhi edunhu akadhindwa (PCBs) kazhinji haatarisirwi munyika yeruzivo rwechizvino-zvino, asi anoita basa guru mumidziyo yese yemagetsi yatinoshandisa nhasi.Ingave iri smartphone yako, laptop, kana kunyange midziyo yakangwara iri mumba mako, maPCB ndiwo magamba asina kusimba anoita kuti zvishandiso izvi zvishande zvisina mutsetse.Mune ino blog, isu tichaongorora munyika yePCBs, toona zvavari uye mashandiro avanoita.
Muviri:
1. Basic ruzivo PCB
A rakadhindwa redunhu bhodhi (PCB) ipepa rakatetepa re insulating zvinhu (kazhinji fiberglass) ine conductive simbi marara akaiswa pairi.Aya makwara anoshanda senzira dzekubatanidza masaini emagetsi pakati pezvinhu zvemagetsi.Saizi, kuoma uye nhamba yezvikamu zvePCB zvinogona kusiyana zvichienderana nezvinodiwa zvechishandiso.
2. Zvikamu zvePCB
MaPCB anoumbwa nezvinhu zvakasiyana zvinosanganisira resistors, capacitors, diode, transistors uye integrated circuits (ICs).Izvi zvikamu zvinotengeswa kuPCB, zvichiita magetsi ekubatanidza pakati pavo.Chikamu chega chega chine basa chairo mudunhu uye chinobatsira pakushanda kwese kwechigadzirwa.
3. Mashandiro anoita PCB
A PCB inoshanda nekubvumira masaini emagetsi kuyerera pakati pezvikamu zvakasiyana, kuve nechokwadi kuti vanotaurirana uye kuita mabasa avo avakagoverwa.Metal traces paPCB inopa nzira dzinodiwa dzekufambisa kwemasaini.Zvikamu paPCB zvakaiswa zvine hungwaru zvinoenderana nedhizaini yedunhu kuti ikwidze basa uye kuderedza kupindira.
4. Nzira yekugadzira
PCBs anogadzirwa kuburikidza nenhevedzano yematanho.Kutanga, dhizaini yedunhu inoitwa uchishandisa komputa-inobatsira dhizaini (CAD) software.Iyo dhizaini inozoendeswa kuPCB uchishandisa photolithographic process.Bhodhi racho rinobva raiswa kubvisa mhangura isingadikanwi uye kusiya chete maronda anodiwa.Pakupedzisira, zvikamu zvinotengeswa pabhodhi uye zvinoongororwa zvehutano zvisati zvabatanidzwa mumagetsi.
5. Zvakanakira uye zvakaipira PCB
MaPCB ane akawanda mabhenefiti akadai sekuvimbika, compactness, kureruka kwekugadzirwa kwakawanda, uye kuyerera kwechiratidzo.Nekudaro, ivo zvakare vane zvisingakwanisi, kusanganisira kusachinjika, kukwira kwekutanga mari yekuseta, uye kudiwa kwehunyanzvi hwekugadzira michina.
Mhedziso
Mabhodhi edunhu akadhindwa (PCBs) ndiwo musimboti wemagetsi emazuva ano, zvichiita kuti zvishandiso zvedu zvemazuva ese zvishande zvisina musono.Kuziva mashandisirwo ePCB kunogona kuwedzera kukoshesa kwedu tekinoroji yakaoma seri kwegajeti.Kubva pane yekutanga chimiro kusvika kune yekugadzira maitiro, iyo PCB chinhu chakakosha chinotyaira kufambira mberi kwetekinoroji.Sezvo isu tichienderera mberi nekumbundira kufambira mberi munharaunda yedhijitari, maPCB pasina mubvunzo acharamba achishanduka uye kugadzira ramangwana remagetsi.
