Ukulawula izindleko ze-PCB kudinga ukwakheka kwebhodi okuqinile, ukudlulisela phambili izichasiselo zakho kubahlinzeki, nokugcina ubudlelwano obuqinile nabo.

Ukukusiza, siqoqe amathiphu angu-8 kumakhasimende nabaphakeli ongawasebenzisa ukuze wehlise izindleko ezingadingekile lapho ukhiqiza ama-PCB.

1.Cabangela ubungako bese uthintana nomkhiqizi

Ngisho nangaphambi kwesigaba sokugcina somklamo wobunjiniyela, izingxoxo nabaphakeli bakho zingakuvumela ukuthi uqale izingxoxo futhi uqonde izinselele ezihlobene nokukhiqiza zephrojekthi yakho.

Kusukela ekuqaleni, cabanga ngamavolumu akho ngokuqoqa ulwazi oluningi ongaluthola kubahlinzeki bakho: izinto ezikhethekile, landelela imininingwane yobuchwepheshe, noma ukubekezelelwa kwebhodi. Ukukhetha okungalungile kungaholela esambeni esikhulu sesikhathi esimoshiwe futhi kudale izindleko ezingadingekile empeleni ezinqunywa ekuqaleni kwesigaba sokuklama. Ngakho-ke zinike isikhathi sokuxoxa futhi uhlole izinzuzo nezinkinga zazo zonke izixazululo ongazithola.

2.Nciphisa ubunkimbinkimbi bebhodi lesifunda

Lena cishe indlela elula yokunciphisa izindleko ze-PCB: thuthukisa ukubekwa kwengxenye yebhodi ngomklamo olula. Unganciphisa izindleko ngokungasebenzisi noma yimaphi amafomu ayinkimbinkimbi futhi unciphise usayizi, kodwa qaphela, kulokhu khumbula ukushiya isikhala esanele phakathi kwento ngayinye.

Amafomu ayinkimbinkimbi, ikakhulukazi lawo angajwayelekile, andisa izindleko. Ukusika kwe-PCB kwangaphakathi kugwenywa kangcono ngaphandle uma kudingekile ukuze kuhlanganiswe okokugcina. Umkhiqizi ukhipha i-invoyisi eyengeziwe kukho konke ukusikeka okwengeziwe. Onjiniyela abaningi bakhetha ukubukeka kwasekuqaleni, kodwa emhlabeni wangempela, lo mehluko awuthinti isithombe somphakathi futhi awungezi noma yikuphi ukusebenza.

3.Chaza usayizi olungile nokujiya

Ifomethi yebhodi inomthelela omkhulu ohlelweni lwezintambo: uma i-PCB incane futhi iyinkimbinkimbi, kuzodingeka isikhathi esiningi nomzamo ukuze umhlanganisi ayiqedele. Osayizi abahlangene kakhulu bayohlala bebiza. Ngakho-ke kuhlale kuyinto enhle ukonga isikhala, sincoma ukuthi singanciphisi ngaphezu kokudingekile ukugwema imisebenzi eminingi ebhodini elifanayo.

Futhi, khumbula ukuthi amafomu ayinkimbinkimbi anomthelela enanini: isikwele noma i-PCB engunxande izokuvumela ukuthi ugcine ukulawula.

Lapho ubukhulu be-PCB bukhula, izindleko zokukhiqiza zizoba phezulu…ngombono noma kunjalo! Inani lezendlalelo ozikhethayo lithinta i-vias yebhodi lesifunda (uhlobo nobubanzi). Uma ibhodi lincanyana, izindleko zebhodi zizonke zingancishiswa, kodwa kungase kudingeke izimbobo ezengeziwe, futhi eminye imishini ngezinye izikhathi ayikwazi ukusetshenziswa nama-PCB azacile. Ukukhuluma nomphakeli wakho kusenesikhathi kuzokusiza wonge imali!

4.Izimbobo nezindandatho ezinosayizi ofanele

Amaphedi amakhulu kanye nezimbobo kulula kakhulu ukuwenza ngoba awadingi imishini enembe kakhulu. Ngakolunye uhlangothi, ezincane zidinga ukulawula okuthambile kakhulu: zithatha isikhathi eside ukwenziwa futhi imishini ibiza kakhulu, okwandisa kakhulu izindleko zakho zokukhiqiza ze-PCB.

5.Xhumana ngedatha ngokucacile ngangokunokwenzeka

Onjiniyela noma abathengi aba-oda ama-PCB abo kufanele bakwazi ukudlulisa isicelo sabo ngokucacile ngangokunokwenzeka, ngemibhalo ephelele (amafayela e-Gerber okuhlanganisa zonke izendlalelo, idatha yokuhlola i-impedance, ukunqwabelanisa okuthile, njll.): ngaleyo ndlela abahlinzeki abanasidingo sokutolika. kanye nezenzo zokulungisa ezidla isikhathi nezimba eqolo zizogwenywa.

Uma ulwazi lungekho, abahlinzeki kufanele bakwazi ukuxhumana namakhasimende abo, bamoshe isikhathi esiyigugu ebesingasetshenziswa kwamanye amaphrojekthi.
Okokugcina, imibhalo ecacile yenza kube nokwenzeka ukuhlonza ukwehluleka okungase kube khona ukugwema ukuqhekeka kanye nokungezwani okuwumphumela wamakhasimende nabaphakeli.

6.Optimise panel

Ukusatshalaliswa okuphelele kwamasekhethi kuphaneli nakho kudlala indima ebalulekile: yonke imilimitha yendawo esetshenzisiwe idala izindleko, ngakho-ke kungcono ukungashiyi isikhala esiningi kakhulu phakathi kwamasekhethi ahlukene. Khumbula ukuthi ezinye izingxenye zingadlulana futhi zidinga isikhala esengeziwe. Uma ipaneli iqine kakhulu kwesinye isikhathi idinga ukusoda okwenziwa ngesandla okuholela ekwenyukeni kwentengo okukhulu.

7.Khetha uhlobo olulungile lwe- via
Izimbobo zokungena zishibhile, kuyilapho izimbobo ezingaboni noma ezishumekiwe zenza izindleko ezengeziwe. Lezi zidingeka kuphela kumabhodi ayinkimbinkimbi, aphezulu noma ama-high frequency board.

Inombolo ye-vias kanye nohlobo lwazo lunomthelela ezindlekweni zokukhiqiza. Amabhodi we-multilayer ngokuvamile adinga izimbobo ezincane zobubanzi.

8.Cabanga kabusha imikhuba yakho yokuthenga

Uma usuzazi zonke izindleko zakho, ungaphinda ubuyekeze amaza okuthenga kwakho nenani. Ngokuhlanganisa ama-oda ungonga amanani amakhulu. Isibonelo, uma uthenga izifunda eziyikhulu izikhathi ezingamashumi amabili ngonyaka, unganquma ukushintsha imvamisa ngoku-oda izikhathi ezinhlanu kuphela ngonyaka.

Qaphela ukuthi ungazigcini isikhathi eside kakhulu ngenxa yengozi yokuphelelwa yisikhathi.

Manje usuyazi ukuthi ungathuthukisa kanjani izindleko ze-PCB yakho ngangokunokwenzeka. Qaphela, ngoba kwezinye izimo, ukwenza ukonga ekudalweni kwesekethe ephrintiwe kungase kungabi umqondo omuhle ngaso sonke isikhathi. Ngisho noma izindleko zehliswa zokukhiqizwa kokuqala, zingabiza kakhulu ngokuhamba kwesikhathi: awusoze waqiniseka ukuthi ngeke kudingeke ukuthi ushintshe amabhodi kaningi… Kuyodingeka futhi ulawule ukunganeliseki kwamakhasimende futhi uthole isixazululo esisha ngokuhamba kwesikhathi. ukuze ugweme lokhu kulahlekelwa.

Noma ngabe yiziphi izinqumo ozenzayo, ekugcineni, ikhambi elingcono kakhulu lokulawula izindleko ukuxoxa ngezinto nabahlinzeki bakho. Bazokwazi ukukunikeza ulwazi olufanele nolulungile ukuze uhlangabezane nezidingo zakho. Bangakusiza ukuthi ulindele izinselele eziningi ongahlangabezana nazo futhi bazokongela isikhathi esiyigugu.
