Njengonjiniyela, siye sacabanga ngazo zonke izindlela isistimu engahluleka ngayo, futhi uma ihluleka, sikulungele ukuyilungisa. Ukugwema amaphutha kubaluleke kakhulu ekwakhiweni kwe-PCB. Ukushintsha ibhodi lesifunda elilimele ensimini kungabiza, futhi ukunganeliseki kwamakhasimende kuvame ukubiza kakhulu. Lesi yisizathu esibalulekile sokukhumbula izizathu ezintathu eziyinhloko zokulimala kwe-PCB enqubweni yokuklama: amaphutha okukhiqiza, izici zemvelo kanye nokuklama okunganele. Nakuba ezinye zalezi zici zingase zingalawuleki, izici eziningi zingancishiswa phakathi nesigaba sokuklama. Yingakho ukuhlela isimo esibi ngesikhathi senqubo yokuklama kungasiza ibhodi lakho lenze inani elithile lokusebenza.

01 Isici sokukhiqiza

Esinye sezizathu ezivamile zokulimala kwebhodi lokuklama kwe-PCB kungenxa yamaphutha okukhiqiza. Lezi ziphambeko zingaba nzima ukuzithola, futhi kube nzima nakakhulu ukuzilungisa uma sezitholakele. Nakuba ezinye zazo zingaklanywa, ezinye kufanele zilungiswe umkhiqizi wenkontileka (CM).

02 isici sezemvelo

Esinye isizathu esivamile sokwehluleka kwedizayini ye-PCB indawo yokusebenza. Ngakho-ke, kubaluleke kakhulu ukuklama ibhodi lesifunda kanye necala ngokusho kwendawo ezosebenza kuyo.

Ukushisa: Amabhodi wesiyingi akhiqiza ukushisa futhi avame ukuchayeka ekushiseni ngesikhathi sokusebenza. Cabangela ukuthi idizayini ye-PCB izozungeza indawo ebiyelwe kuyo, ichayeke elangeni namazinga okushisa angaphandle, noma imunce ukushisa kweminye imithombo eseduze. Ukushintsha kwezinga lokushisa nakho kungaqhekeka amalunga e-solder, izinto eziyisisekelo ngisho nezindlu. Uma isifunda sakho singaphansi kwamazinga okushisa aphezulu, ungase udinge ukufunda ngezingxenye zembobo, ezivame ukuphatha ukushisa okukhulu kune-SMT.

Uthuli: Uthuli luyindlala yemikhiqizo kagesi. Qinisekisa ukuthi ikesi lakho linesilinganiso se-IP esilungile kanye/noma ukhethe izingxenye ezingaphatha amazinga othuli alindelekile endaweni yokusebenza kanye/noma zisebenzise ama-coatings avumelanayo.

Umswakama: Umswakama ubeka usongo olukhulu emishinini kagesi. Uma idizayini ye-PCB isebenza endaweni enomswakama kakhulu lapho izinga lokushisa lishintsha ngokushesha, umswakama uzofinyana usuka emoyeni uye kusekethe. Ngakho-ke, kubalulekile ukuqinisekisa ukuthi izindlela zokufaka umswakama zihlanganiswa kulo lonke isakhiwo sebhodi lesifunda nangaphambi kokufakwa.

Ukudlidliza komzimba: Kunesizathu sezikhangiso eziqinile ze-elekthronikhi abantu abaziphonsa emadwaleni noma phansi kukakhonkolo. Ngesikhathi sokusebenza, amadivaysi amaningi angaphansi kokushaqeka ngokomzimba noma ukudlidliza. Kumele ukhethe amakhabethe, amabhodi wesifunda kanye nezingxenye ezisekelwe ekusebenzeni kwemishini ukuxazulula le nkinga.

03 Idizayini engaqondile

Isici sokugcina somonakalo webhodi le-PCB ngesikhathi sokusebenza sibaluleke kakhulu: ukuklama. Uma inhloso kanjiniyela kungekona ukufeza imigomo yakhe yokusebenza; okuhlanganisa ukwethembeka nokuphila isikhathi eside, lokhu kumane nje kungenakufinyeleleka. Uma ufuna ibhodi lakho lesifunda lihlale isikhathi eside, qiniseka ukuthi ukhetha izingxenye nezinto zokwakha, wendlale ibhodi lesifunda, futhi uqinisekise ukuklama ngokwezidingo ezithile zomklamo.

Ukukhethwa kwengxenye: Ngokuhamba kwesikhathi, izingxenye zizohluleka noma ziyeke ukukhiqiza; nokho-ke, akwamukelekile ukuthi lokhu kwehluleka kwenzeke ngaphambi kokuthi kuphele isikhathi sokuphila kwebhodi. Ngakho-ke, ukukhetha kwakho kufanele kuhlangabezane nezidingo zokusebenza kwendawo yakhona futhi kube nomjikelezo wokuphila wengxenye eyanele phakathi nomjikelezo wokuphila wokukhiqiza olindelekile webhodi lesekethe.

Ukukhetha izinto ezibonakalayo: Njengoba nje ukusebenza kwezingxenye kuzohluleka ngokuhamba kwesikhathi, kanjalo nokusebenza kwezinto zokwakha. Ukuchayeka ekushiseni, ukuhamba ngebhayisikili elishisayo, ukukhanya kwe-ultraviolet, kanye nengcindezi yemishini kungabangela ukuwohloka kwebhodi lesifunda kanye nokwehluleka ngaphambi kwesikhathi. Ngakho-ke, udinga ukukhetha izinto zebhodi lesifunda ezinemiphumela emihle yokunyathelisa ngokusho kohlobo lwebhodi lesifunda. Lokhu kusho ukucabangela izakhiwo zezinto ezibonakalayo nokusebenzisa izinto ezingasebenzi kakhulu ezifanele umklamo wakho.

Isakhiwo somklamo we-PCB: Isakhiwo somklamo we-PCB esingacacile singase sibe imbangela eyinhloko yokwehluleka kwebhodi lesifunda phakathi nokusebenza. Isibonelo, izinselele eziyingqayizivele zokungafaki amabhodi anamandla kagesi aphezulu; njengesilinganiso sokulandelela i-arc ephezulu ye-voltage, kungabangela ukulimala kwebhodi lesifunda kanye nesistimu, futhi kubangele nokulimala kubasebenzi.

Ukuqinisekiswa kwedizayini: Lesi kungaba isinyathelo esibaluleke kakhulu ekukhiqizeni isekethe ethembekile. Yenza ukuhlola kwe-DFM nge-CM yakho ethile. Amanye ama-CM angagcina ukubekezelelana okuqinile futhi asebenze ngezinto ezikhethekile, kuyilapho amanye engakwazi. Ngaphambi kokuthi uqale ukukhiqiza, qiniseka ukuthi i-CM ingakwazi ukwenza ibhodi lakho lesifunda ngendlela ofuna ngayo, ezoqinisekisa ukuthi idizayini ye-PCB yekhwalithi ephezulu ngeke yehluleke.

Akuthakazelisi ukucabanga isimo esibi kakhulu se-PCB design. Ukwazi ukuthi uklame ibhodi elithembekile, ngeke lihluleke lapho ibhodi lithunyelwa kukhasimende. Khumbula izizathu ezintathu eziyinhloko zokulimala komklamo we-PCB ukuze ukwazi ukuthola ngokushelelayo ibhodi lesifunda elingaguquki nelithembekile. Qiniseka ukuthi uhlelela amaphutha okukhiqiza kanye nezici zemvelo kusukela ekuqaleni, futhi ugxile ezinqumweni zokuklama zamacala athile.
