Njengonjiniyela, sicabange ngazo zonke izindlela uhlelo olungahluleka khona, futhi uma selihluleka, sikulungele ukulilungisa. Ukugwema amaphutha kubaluleke kakhulu ku-PCB Design. Ukushintsha ibhodi yesekethe ekonakalisiwe emkhakheni kungabiza, futhi ukunganeliseki kwamakhasimende kuvame ukubiza kakhulu. Lesi yisizathu esibalulekile sokukhumbula izizathu ezintathu eziphambili zomonakalo we-PCB kwinqubo yokwakha: Izinkinga zokukhiqiza, izici zezemvelo nokuklanywa okunganele. Yize ezinye zalezi zinto zingase zingalawulwa, izici eziningi zingancishiswa ngesikhathi sesigaba sokuklama. Kungakho ukuhlela isimo esibi ngesikhathi senqubo yokuqamba kungasiza ibhodi yakho ukuthi yenze inani elithile lokusebenza.

01 ISIQINISEKISO SEZIMALI

Enye yezizathu ezijwayelekile zomonakalo we-PCB Design Board kungenxa yezimpawu zokukhiqiza. Lezi ziphambeko zingaba nzima ukuzithola, futhi kube nzima ngokwengeziwe ukulungisa uma sekutholakele. Yize ezinye zazo zihlelwe, ezinye kumele zilungiswe ngumkhiqizi wesivumelwano (cm).

I-02 envirnmental factor

Enye imbangela evamile yokuhluleka kwe-PCB yindawo yokusebenza. Ngakho-ke, kubaluleke kakhulu ukuklama ibhodi yesekethe kanye necala ngokuya ngemvelo lapho izosebenza khona.

Ukushisa: Amabhodi wesekethe akhiqiza ukushisa futhi avame ukuvezwa ukushisa ngesikhathi sokusebenza. Cabanga ukuthi ukwakheka kwe-PCB kuzojikeleza lapho ebiyelwe kuyo, kuvezwe ukukhanya kwelanga namazinga okushisa angaphandle, noma ukudonsa ukushisa kweminye imithombo eseduze. Izinguquko zokushisa zingavimbela futhi ukuhlanganisa amalunga womthengisi, impahla eyisisekelo ngisho nezindlu. Uma umjikelezo wakho ungaphansi kwamazinga okushisa aphezulu, kungadingeka ukuthi utadishe izingxenye ze-hair-hole, okuvame ukwenza ukushisa okuningi kune-SMT.

Uthuli: Uthuli yi-bane yemikhiqizo ye-elekthronikhi. Qinisekisa ukuthi icala lakho linesilinganiso esifanele se-IP kanye / noma khetha izingxenye ezingaphatha amazinga alindelekile wothuli endaweni yokusebenza kanye / noma asebenzise izimbobo ezi-combal.

Umswakama: Umswakama ubeka usongo olukhulu emishini ye-elekthronikhi. Uma ukwakhiwa kwe-PCB kusebenza endaweni enomswakama kakhulu lapho izinga lokushisa lishintsha ngokushesha, umswakama uzokuthola emoyeni esifundazweni. Ngakho-ke, kubalulekile ukuqinisekisa ukuthi izindlela zokufakazela umswakama zifakwa kulo lonke isakhiwo sebhodi lesekethe futhi ngaphambi kokufakwa.

Ukudlidliza ngokomzimba: Kunesizathu sezikhangiso eziqinile ze-elekthronikhi abantu abaziphonsa phansi edwaleni noma ekhonkolo. Ngesikhathi sokusebenza, amadivaysi amaningi angaphansi kokushaqeka ngokomzimba noma ukudlidliza. Kufanele ukhethe amakhabethe, amabhodi wesifunda kanye nezinto ezisuselwa ekusebenzeni kwemishini ukuxazulula le nkinga.

03 design okungeyona eyenziwe

Isici sokugcina somonakalo we-PCB Design Board ngenkathi usebenza okubaluleke kakhulu: Design. Uma inhloso yonjiniyela ingeyona imininingwane ngokuqondile ukufeza izinhloso zayo zokusebenza; kufaka phakathi ukuthembeka nokuphila isikhathi eside, lokhu kumane nje kungafinyeleleki. Uma ufuna ibhodi lakho lesekethe lihlale isikhathi eside, qiniseka ukuthi ukukhetha izakhi nezinto zokwakha, faka ibhodi yesekethe, futhi uqinisekise ukwakhiwa ngokuya ngezidingo ezithile zedizayini.

Ukukhetha kwengxenye: Ngokuhamba kwesikhathi, izakhi zizokwehluleka noma ziyeke ukukhiqizwa; Kodwa-ke, akwamukeleki kulokhu kwehluleka ukwenzeka ngaphambi kokuba impilo elindelekile yeBhodi iphelelwe yisikhathi. Ngakho-ke, ukukhetha kwakho kufanele kuhlangabezane nezidingo zokusebenza kwendawo yayo futhi kube nomjikelezo owenele wokuphila ngesikhathi somjikelezo wokuphila okulindelekile webhodi yokukhiqiza.

Ukukhethwa kwezinto ezibonakalayo: Njengoba ukusebenza kwezakhi kuzohluleka ngokuhamba kwesikhathi, ngakho-ke ukusebenza kwezinto zokwakha. Ukuchayeka ekushiseni, ukuhamba ngebhayisikile okushisayo, ukukhanya kwe-ultraviolet, kanye nengcindezi yemishini kungenza ukucekelwa phansi kwesifunda kanye nokwehluleka ngaphambi kwesikhathi. Ngakho-ke, udinga ukukhetha izinto zokwenziwa zebhodi ngemiphumela emihle yokuphrinta ngohlobo lweBhodi Yesekethe. Lokhu kusho ukucabanga ngezakhiwo ezibonakalayo kanye nokusebenzisa izinto ezisetshenziswa kakhulu ezilungele ukwakheka kwakho.

Isakhiwo se-PCB Design Isibonelo, izinselelo ezihlukile zokungafaki amabhodi aphezulu e-voltage; Njengezinga eliphakeme lokulandela umkhondo we-arc, kungadala ukulimala kwesekethe kanye nomonakalo wesistimu, futhi kubangele ukulimala kwabasebenzi.

Ukuqinisekiswa komklamo: Lokhu kungaba isinyathelo esibaluleke kakhulu ekukhiqizeni umjikelezo onokwethenjelwa. Yenza amasheke we-DFM nge-cm yakho ethile. Amanye ama-CM angagcina ukubekezelelana nokuqina futhi asebenze ngezinto ezikhethekile, kanti amanye angeke. Ngaphambi kokuthi uqale ukukhiqiza, qiniseka ukuthi i-CM ingakha iBhodi yakho yesekethe ngendlela ofuna ngayo, ezoqinisekisa ukuthi ukwakheka kwekhwalithi ephezulu ye-PCB A ngeke kwehluleke.

Akumnandi ukucabanga ngesimo esibi kakhulu sokwakhiwa kwe-PCB. Ukwazi ukuthi wenza ibhodi elithembekile, ngeke lehluleke lapho iBhodi lithunyelwa kwikhasimende. Khumbula izizathu ezintathu eziyinhloko zomonakalo we-PCB Design ukuze ukwazi ukuthola kahle ibhodi yesekethe futhi ethembekile yesekethe. Qinisekisa ukuhlela iziphambeko zokukhiqiza kanye nezici zezemvelo kusukela ekuqaleni, futhi ugxile ezinqumweni zokuqamba amacala athile.
