Iyini incazelo ye PCB inqubo? Okulandelayo, ngizochaza incazelo yenqubo ye-PCB. Lo mbhalo uzochaza inqubo yokukhiqiza ye-PCB nezidingo zabakhiqizi. Ngokuya ngeziqu noma izingqinamba zomkhiqizi, zingaqoqwa ngaphansi kwesigaba esibizwa ngokuthi “izinqubo”. Lezi zigaba zinqunywa ngokuyinhloko ngesisekelo sezindleko. Ukuphakama kwenqubo yenqubo, izindleko ziya phezulu. Izigaba zenqubo zisiza abaklami ukulawula izindleko ngokukhawulela umklamo.

Izingxenye ezilandelayo zichaza umehluko phakathi kwezinqubo ezahlukahlukene, zichaza izingqinamba zokukhiqiza, futhi zingene ngemininingwane ngenqubo ngayinye, ikakhulukazi inqubo yendabuko nokuthi umqambi uwabhala kanjani amanothi okukhiqiza nemiyalo yesinyathelo ngasinye.

Amanothi okukhiqiza omklami angaba iqoqo lamanothi asuselwa embhalweni anamathiselwe kufayela ledatha le-A PCB (njengefayela leGerber noma elinye ifayili ledatha), noma anganikezwa ngumdwebo we-PCB uqobo, oxhumana nezidingo nemininingwane yomklami inqubo yokukhiqiza. Ukwenza imibono kungenye yezingxenye eziyindida kakhulu nezididayo zenqubo ye-PCB. Abaqambi abaningi abazi ukuthi bawabona kanjani lawa mazwana noma ukuthi benzeni. Lokhu kwenziwa kube nzima kakhulu ngamakhono ahlukahlukene okukhiqiza abakhiqizi kanye nokuntuleka kweziqondiso ezifanele. Umqambi kufanele abuze imibuzo eminingana futhi aqonde inqubo yokukhiqiza ngaphambi kokuyalela umkhiqizi ukuthi akhiqize kanjani.

Manje kungani uphawula? Amazwana enziwa ukuthi angavimbeli abakhiqizi kepha ahlinzeke ngokuvumelana nendawo yokuqala ebaluleke kakhulu lapho kuzanywa ukulungisa amanani athile. Amanani ashiwo kuleli phepha asuselwa kuzinqubo ezivamile.

Manje yini ubuciko? Ubuciko ulwazi lokuthi ungadala kanjani, wenze noma ufeze umgomo noma umsebenzi othile. Ekuklanyweni kwe-PCB, inqubo yethemu ayibhekiseli esigabeni sedatha yenqubo kuphela, kepha futhi nakumakhono womenzi. Le mininingwane isuselwa ekusebenzeni kwemishini yomkhiqizi kanye nenqubo yokuklama iyonke.

Amaphuzu amathathu wokulawula yi-etCH, Drill nokubhaliswa. Ezinye izakhiwo zithinta isigaba sonke senqubo, kepha lawa maphuzu amathathu abaluleke kakhulu.

Phambilini, yayingekho imithetho ecacile yalezi zinqubo. Ngenxa yokwesaba ukuxosha amakhasimende noma ukuveza imininingwane eminingi kakhulu kulabo abancintisana nabo, abenzi babengenayo intshisekelo ngokuthuthukisa imikhakha yenqubo enjalo, futhi kwakungekho nhlangano noma iqembu lokuqopha nokuhlela imininingwane. Ngakho-ke, lapho kuthuthukiswa imboni ye-PCB, kancane kancane yakha inqubo yesigaba senqubo, ihlukaniswe ngezigaba zenqubo ezine ezilandelayo: ezivamile, ukuhola okuthuthukile kanye nokuthuthuke kakhulu. Njengoba inqubo ithuthukiswa, idatha ivuselelwa njalo, ngakho-ke imininingwane yesigaba senqubo iyashintsha. Izigaba zezinqubo nezincazelo zazo ezijwayelekile zingokulandelayo:

Amabanga aphansi futhi ajwayelekile kunawo wonke——– inqubo ngokuvamile ichazwa njenge-0.006 in. /0.006 in. (6 / 6mil) wire wire / spacing, 0.012 in. (0.3048cm) imbobo encane eboshiwe, kanye nobukhulu obungu-8- Izendlalelo eziyi-10 ze-PCB, inqobo nje uma kusetshenziswa ounce elilodwa le-foil yethusi.

Inqubo ethuthukile ——- isigaba 2 senqubo, esinomkhawulo wenqubo ka-5 / 5mil, ubuncane obungu-0.008 in. (0.2032com) imbobo eboshiwe, kanye nobubanzi bezingqimba ze-PCB eziyi-15-20.

Inqubo eholayo ——— ngokuyisisekelo ileveli ephezulu kakhulu yokukhiqiza esetshenziswa kakhulu, nemikhawulo yenqubo ecishe ibe ngu-2 / 2mil, ubukhulu obuncane bomgodi wokuqedela obungu-0.006 in. (0.1524cm), kanye nenombolo enkulu yezendlalelo ze-PCB ezingama-25-30.

Izinqubo ezithuthuke kakhulu ——– azichaziwe ngokucacile ngoba izinqubo ezikulelizinga zihlala ziguquka futhi idatha yazo izoshintsha ngokuhamba kwesikhathi futhi idinga ukulungiswa njalo. (Qaphela: imininingwane eminingi ejwayelekile yezinqubo embonini isuselwa kunqubo ejwayelekile kusetshenziswa u-0.5 oz woqwembe lokuqala lwethusi.)
