Weiwenxin PCBworld] Mukutsvagirwa kwePCB reverse tekinoroji, reverse push musimboti unoreva kudzosera kumashure kunze zvinoenderana nePCB gwaro rekudhirowa kana kudhirowa zvakananga PCB redunhu dhayagiramu zvinoenderana nechigadzirwa chaicho, chine chinangwa chekutsanangura musimboti uye mamiriro ekushanda edunhu. board.Uyezve, iyi dhizaini yedunhu inoshandiswawo kuongorora maitiro ekushanda echigadzirwa pachacho.Mukugadzira kumberi, kugadzirwa kwechigadzirwa kwakawanda kunofanirwa kutanga kwaita dhizaini, uyezve kuita iyo PCB dhizaini zvinoenderana nehurongwa.

Kunyangwe ichishandiswa kuongorora masimboti ebhodhi redunhu uye mashandiro echigadzirwa mukutsvagisa, kana kushandiswa zvakare sehwaro uye hwaro hwePCB dhizaini mukugadzira kumberi, PCB schematics ine basa rakakosha.Saka, sei kudzosera PCB schematic dhizaini zvichibva pane gwaro dhayagiramu kana chinhu chaicho?Ndeapi madeti anofanirwa kutariswa panguva yereverse calculation process?

Kuparadzaniswa kunonzwisisika kwenzvimbo dzinoshanda
01

Paunenge uchiita reverse dhizaini yedhizaini yeakanaka PCB redunhu bhodhi, kupatsanurwa kwakanaka kwenzvimbo dzinoshanda kunogona kubatsira mainjiniya kuderedza mamwe matambudziko asina basa uye kuvandudza kugona kwekudhirowa.Kazhinji kutaura, zvikamu zvine basa rimwechete paPCB board zvakarongwa nenzira yakamisikidzwa, uye kupatsanurwa kwenzvimbo nebasa kunogona kuve nekwakanaka uye kwakaringana pakutenderedza dhiyagiramu yehurongwa.

Zvisinei, kupatsanurwa kwenzvimbo iyi inoshanda hakusi kungopokana.Zvinoda mainjiniya kuti ave nekunzwisisa kwemagetsi edunhu ane chekuita neruzivo.Kutanga, tsvaga chikamu chepakati mune imwe yuniti inoshanda, uye zvino maererano nekubatanidza wiring, unogona kuwana zvimwe zvikamu zveiyo imwechete inoshanda unit munzira yekugadzira inoshanda partition.Kuumbwa kwezvikamu zvinoshanda ndiyo hwaro hwekudhirowa kwechirongwa.Mukuwedzera, mukuita uku, usakanganwa kushandisa serial nhamba dzezvikamu pabhodhi redunhu zvine hungwaru, dzinogona kukubatsira kugovera mabasa nekukurumidza.

Nyatsosiyanisa mitsetse uye dhirowa wiring zvine musoro

Pamusiyano pakati pewaya dzepasi, waya dzemagetsi, uye waya dzechiratidzo, mainjiniya anofanirwawo kuve neruzivo rwakakodzera rwemagetsi, ruzivo rwekubatanidza redunhu, ruzivo rwePCB wiring, zvichingodaro.Kusiyana kwemitsara iyi kunogona kuongororwa maererano nekubatana kwezvikamu, hupamhi hwemhangura yemhangura yemutsara, uye maitiro echigadzirwa chemagetsi pachako.

Mukudhirowa wiring, kuitira kuti udzivise kuyambuka uye kupindirana kwemitsara, nhamba huru yezviratidzo zvepasi inogona kushandiswa kumutsara wepasi.Mitsetse yakasiyana-siyana inogona kushandisa mavara akasiyana uye mitsetse yakasiyana-siyana kuti ive nechokwadi chokuti yakajeka uye inoziva.Kune zvikamu zvakasiyana-siyana, zviratidzo zvakakosha zvinogona kushandiswa, kana kunyange Dhirowa zvikwata zvechikwata zvakasiyana uye uzvisanganise pakupedzisira.

Tsvaka mareferensi ezvikamu

Ichi chikamu chereferensi chinogona zvakare kunzi ndicho chikamu chikuru chakashandiswa pakutanga kwekudhirowa kwechirongwa.Mushure mekunge chikamu chereferensi chatemerwa, chikamu chereferenzi chinodhirowewa zvinoenderana nemapini ezvikamu zvereferenzi izvi, izvo zvinogona kuve nechokwadi chechokwadi cheiyo schematic dhizaini kusvika pamwero mukuru.

Kune mainjiniya, kutsunga kwezvikamu zvereferenzi haisi nyaya yakaoma.Mumamiriro ezvinhu akajairika, zvikamu zvinoita basa guru munharaunda zvinogona kusarudzwa sezvikamu zvemashoko.Iwo kazhinji akakura muhukuru uye ane mamwe mapini, ayo ari nyore kudhirowa.Zvakadai semaseketi akabatanidzwa, ma transformer, transistors, nezvimwe, ese anogona kushandiswa seakakodzera mareferensi zvikamu.

Nyatsojairika dhizaini uye dzidza kubva kune akafanana schematic diagram

Kune mamwe ekutanga emagetsi edunhu dhizaini kuumbwa uye musimboti wekudhirowa nzira, mainjiniya anofanirwa kuve nehunyanzvi, kwete chete kuti vakwanise kudhirowa zvakananga mamwe akareruka uye echinyakare unit maseketi, asiwo kugadzira iyo yakazara furemu yemaseketi emagetsi.

Kune rumwe rutivi, usakanganwa kuti mhando imwechete yezvigadzirwa zvemagetsi zvine imwe yakafanana mumadhayagiramu ehurongwa.Mainjiniya anogona kushandisa kuunganidza kwechiitiko uye kudzidza zvizere kubva kune akafanana edunhu madhayagiramu kudzoreredza dhizaini yezvigadzirwa zvitsva.

Tarisa uye gadzirisa

Mushure mekudhirowa kwechirongwa kwapera, dhizaini yakadzoserwa yePCB schematic inogona kunzi inopedzwa mushure mekuedzwa uye kuongororwa.Iko kukosha kwezita kwezvikamu zvinonzwa kune PCB yekugovera paramita inoda kutariswa uye kugadziridzwa.Zvinoenderana neiyo PCB faira dhayagiramu, iyo schematic dhizaini inofananidzwa uye kuongororwa kuti ive nechokwadi chekuti dhizaini yedhizaini inonyatsoenderana nedhiyagiramu yefaira.
