Lapho ukhetha uhlobo oluthile ibhodi yesifunda ephrintiwe (eyaziwa nangokuthi yi-PCB), ungazibuza ukuthi inembe kangakanani inqubo yenhlangano ye-PCB. Ukukhiqizwa kwe-PCB kushintshe kakhulu eminyakeni edlule, ngenxa yemisebenzi emisha kubuchwepheshe obusha obuvumele abakhiqizi bebhodi lesifunda ukuthi basungule ngokunembile nangobungcweti.

Nakhu ukuthi ungayenza kanjani i-PCB eyisibonelo ngokunembile.

Front ekupheleni engineering ukuhlolwa

Ngaphambi kokufaka i-PCB, kunezici ezingenakubalwa ezingasetshenziswa ukuhlela umphumela wokugcina. Okokuqala, umenzi we-PCB uzofunda ngokucophelela ukwakheka kwebhodi (idokhumenti yeGerber) bese eqala ukulungiselela ibhodi, elibala uhlu lwemiyalo yokwenziwa kwesinyathelo ngesinyathelo. Ngemuva kokubuyekezwa, onjiniyela bazoguqula lezi zinhlelo zibe yifomethi yedatha ezosiza ukuklama i-PCB. Unjiniyela uzophinde ahlole ifomethi nganoma yiziphi izinkinga noma ukuhlanzwa.

Le datha isetshenziselwa ukudala ibhodi lokugcina futhi ilinikeze ngenombolo yethuluzi elihlukile. Le nombolo ilandelela inqubo yokwakhiwa kwe-PCB. Ngisho nezinguquko ezincane kakhulu ekubuyekezweni kwebhodi zizoholela enombolweni yamathuluzi entsha, esiza ukuqinisekisa ukuthi akukho kudideka ngesikhathi se-PCB nokwenziwa kwama-oda amaningi.

umdwebo

Ngemuva kokubheka amafayela afanele nokukhetha uhlu lwamaphaneli afanele kakhulu, ukuphrinta kwesithombe kuqala. Lokhu kungukuqala kwenqubo yokukhiqiza. Ama-Photoplotters asebenzisa ama-lasers ukudweba amaphethini, izikrini zikasilika nezinye izithombe ezinkulu kwi-PCB.

Ukunamathisela nokubhola

Olunye lwezinhlobo ezintathu eziyinhloko zamabhodi wesifunda aphrintiwe, awaziwa njenge-multilayer PCBS, adinga i-lamination ukuhlanganisa izingqimba ndawonye. Lokhu kuvame ukwenziwa kusetshenziswa ukushisa nokucindezela.

Ngemuva kokunamathisela umkhiqizo, uhlelo lokubhola lochwepheshe luyohlelwa ukuthi lubambe ngokunembile nangokuqonde okhunini. Inqubo yokubhola iqinisekisa ukuthi akukho phutha lomuntu ngesikhathi sokukhiqizwa kwe-PCB.

Ukufakwa kwe-Copper nokufakwa

Izendlalelo zethusi ezisebenzayo ezifakwa yi-electrolysis zibalulekile ekusebenzeni kwawo wonke amabhodi wesekethe aphrintiwe. Ngemuva kwe-electroplating, i-PCB ngokusemthethweni iba yindawo eqhubayo futhi ithusi liqokelwe kule ndawo ngesixazululo se-electroplating. Lezi zintambo zethusi ziyizindlela ezihambayo ezixhuma amaphuzu amabili ngaphakathi kwe-PCB.

Ngemuva kokwenza izivivinyo zokuqinisekisa ikhwalithi ku-PCB eyisibonelo, zenziwa zaba izingxenye ezihlukanisiwe futhi ekugcineni zahlolwa ukuhlanzeka.
