Inqubo ye-PCB Board Etching, esebenzisa izinqubo zendabuko zamakhemikhali ezi-etching ukuze zenziwe izindawo ezingavikelekile. Uhlobo lokumba umsele, indlela esebenzayo kodwa engasebenzi kahle.

Enqubweni ye-etching, kuhlukaniswe nenqubo enhle yamafilimu kanye nenqubo engemihle yefilimu. Inqubo enhle yamafilimu isebenzisa i-tin ehleliwe ukuvikela umjikelezo, futhi inqubo engemihle yefilimu isebenzisa ifilimu eyomile noma ifilimu elimanzi ukuvikela umjikelezo. Imiphetho yemigqa noma amaphakethe yi-misshapen ngendabukoUkufakaIzindlela. Njalo lapho umugqa ukhuphulwa ngo-0.0254mm, onqenqemeni luzothambekela ngezinga elithile. Ukuqinisekisa ukuhlukaniswa okwanele, igebe le-wire lihlala lilinganiswa endaweni esondele kakhulu yocingo ngalunye lokusetha kwangaphambili.

Kuthatha isikhathi esithe xaxa sokuthola i-ounce yethusi ukuze wakhe igebe elikhudlwana ku-void of wire. Lokhu kubizwa ngokuthi i-ETCH Factor, futhi ngaphandle komenzi okuhlinzeka ngohlu olucacile lwezikhala ezimbalwa ze-OUD ngayinye yethusi, funda into e-ETCH yomenzi. Kubaluleke kakhulu ukubala umthamo omncane we-Ounce ngethusi. Isici se-ETCH futhi sithinta umgodi wokukhala komenzi. Usayizi wendandatho yendandatho yendandatho ngu-0.0762mm ukucabanga + 0.0762mm ukumba + 0.0762 ukugcwambeka, ingqikithi ye-0.2286. I-ETCH, noma i-ETCH factor, ingenye yemigomo emine eyinhloko ecacisa ibanga lenqubo.

Ukuze uvikele ungqimba oluvikelayo ekuweni futhi uhlangabezane nezidingo zokuhlukanisa izikhala zamakhemikhali e-etching yamakhemikhali, i-turchi yendabuko ichaza ukuthi ukuhlukaniswa okuncane phakathi kwezintambo akufanele kube ngaphansi kwe-0.127mm. Uma kucatshangelwa into yokugqwala kwangaphakathi nokukhuphuka ngesikhathi senqubo ye-etching, ububanzi bentambo kufanele bukhuphuke. Leli nani linqunywa ngobukhulu besendlalelo esifanayo. I-Swearer ungqimba lwethusi, uma kuthatha isikhathi eside ukudonsa ithusi phakathi kwezintambo nangaphansi kokuhlobana okuvikelayo. Ngenhla, kunemininingwane emibili okufanele icatshangwe ukuthi i-chemical tching: i-eTch factor - inani le-etched etched nge-eunce ngayinye; kanye negebe eliphansi noma ububanzi be-pitch nge-eunce ngethusi.
