Mukutsvaga kwe PCB reverse tekinoroji, regedza kusunda schematic dhayagiramu inoreva kushanduka kwePCB faira dhayagiramu kana pcb redunhu dhayagiramu yakadhonzwa zvakananga zvinoenderana nechakwo chinhu chechigadzirwa, kuitira kuti utsanangure musimboti uye nekushanda mamiriro wedunhu bhodhi. Uye zvakare, dhayagiramu yedunhu inoshandiswa zvakare kuongorora hunhu hunoshanda hwechigadzirwa pachacho. Mukumberi dhizaini, general chigadzirwa budiriro inofanira kutanga yaita yechirume dhizaini, uyezve woita pcb dhizaini maererano neshemera dhizaini.

Iyo PCB schematic ine basa rakakosha, kunyangwe kana ichizoshandiswa kuongorora wedunhu bhodhi misimboti uye chigadzirwa mashandiro maitiro mune reverse kudzidza, kana sehwaro uye hwaro hwePCB dhizaini kumberi dhizaini. Saka, maitiro ekushandura iyo PCB schematic, uye ndeapi ruzivo anofanirwa kutendeuka maitiro kuteedzera, zvichibva pane zvinyorwa kana zvinhu chaizvo?

1. Zvinonzwisisika kupatsanura nzvimbo dzinoshanda

Kana iyo schematic dhizaini pcb bhodhi yakagadziridzwa kugadziridzwa, iko kunonzwisisika kupatsanurwa kweanoshanda nzvimbo dzinogona kubatsira mainjiniya kudzikisira zvisina basa dambudziko uye nekuvandudza mashandiro ekudhirowa.Kazhinji, zvinoriumba zvine basa rakafanana paPCB zvicharongedzwa nenzira yepakati, uye nzvimbo inoshanda inokamura nzvimbo inogona kuve neyakareruka uye yakajeka hwaro kana schematic yadzoserwa. Nekudaro, kupatsanurwa kwenzvimbo ino inoshanda hakusi kwekumanikidza. Zvinoda mainjiniya kuti ave nekumwe kunzwisisa kweyemagetsi wedunhu inoenderana neruzivo. Chekutanga, tsvaga izvo zvakakosha zvinhu muchikamu chinoshanda, uyezve zvinoenderana neiyo trace yekubatana, tsvaga zvimwe zvikamu zveiyo imwechete inoshanda unit, uye gadzira chinoshanda chikamu. Kuumbwa kwezvikamu zvinoshanda ndiyo hwaro hwechirongwa. Zvakare, usakanganwa kushandisa echikamu serial manhamba pabhodhi panguva yekuita, izvo zvinogona kukubatsira iwe kugovera mashandiro mashandiro nekukurumidza.

2. Tsvaga mabhenji

Ichi chirevo chinogona zvakare kunzi ndicho chikuru chikamu chePCB kopi bhodhi pakutanga kwekucheka dhizaini. Mushure mekuratidzwa kwenongedzo, kudhirowa zvinoenderana nemapini ezvinongedzo izvi kunogona kuve nechokwadi chedhiraimendi yedanho kusvika padanho rakakura. Kutsunga kwechikamu chinongedzera harisi dambudziko rakaomarara kune mainjiniya. Kazhinji, chinhu icho chinoita basa rakakura mudunhu chinogona kusarudzwa sechinhu chinongedzo. Iwo anowanzo kuve makuru uye ane mapini mazhinji, ayo ari nyore kutambanudza. Senge maseketi akabatanidzwa, maTransformers, maTransistors, nezvimwe, anogona kushanda senge yakakodzera mareferenzi.

3, inonyatso kusiyanisa mitsara, mutsara unonzwisisika

Kuti ugone kusiyanisa ivhu, simba uye mitsara yemasaini, mainjiniya anodawo kuve neruzivo rwemagetsi, kubatanidza wedunhu, pombi yePCB zvichingodaro. Misiyano iri pakati peaya waya inogona kuongororwa kubva kune zvinobatana zvezvinhu, hupamhi hwemhangura foil mudunhu, uye hunhu hwemagetsi iwo pachawo. Mumadhirowa ewiring, waya dzepasi dzinogona kushandiswa muhuwandu hwakawanda hwezviratidzo zvepasi kudzivirira kuyambuka nekuparadzira mitsara. Mitsara inogona kusiyaniswa zvakajeka nekushandisa mitsara dzakasiyana mumarudzi akasiyana, uye zviratidzo zvakakosha zvinogona kushandiswa pazvinhu zvakasiyana siyana, uye kunyangwe maseketi euniti anogona kudhonzwa mumwe nemumwe uye pakupedzisira anosanganiswa.

4. Tenzi hwaro hwekutanga uye tarisa kune akafanana madhimoni madhirama

Kune mamwe akakosha emagetsi wedunhu furemu uye nzira yekudhirowa, mainjiniya anofanirwa kugona, kwete chete kudhirowa zvirinyore kuumbwa kweimwe yakapusa uye yakasarudzika unit wedunhu, asi zvakare inoumba hwaro hwese hweseketi yemagetsi. Kune rimwe divi, usaregeredze zvakafanana zvigadzirwa zvemagetsi muPCB kopi bhodhi schematic diagram ine zvimwe zvakafanana. Mainjiniya anogona kushandisa zvizere masikemu akafanana kuti aite reverse yechitsva chigadzirwa schematics zvichibva pane zvakaitika.

5. Tarisa uye gadzirisa

Mushure mekupedza iyo schematic, iwe unofanirwa kudzosera dhizaini iyo PCB schematic nekuyedza uye kutarisa izvo zvinongedzo. Iwo mazita ezvinhu zvezvinhu zvinoenderana nePCB yekuparadzira parameter inoda kuongororwa uye kukwidziridzwa. Zvinoenderana nePCB faira yekudhirowa, iyo schematic dhizaini inofananidzwa uye kuongororwa kuti ive nechokwadi chekuti schematic kudhirowa yakanyatso fanika neiyo faira kudhirowa. Kana marongero echirongwa akawanikwa asingakwanise zvinodiwa panguva yekutarisa, iyo schematic ichagadziriswa kusvikira zvanyatsonzwisisika, zvakaenzana, zvakarurama uye zvakajeka.
