Xa ukhetha iprototype ibhodi yesekethe eprintiweyo (ekwabizwa ngokuba yi-PCB), usenokuzibuza ukuba ichane kangakanani inkqubo yendibano ye-PCB. Ukuveliswa kwe-PCB kutshintshe kakhulu kule minyaka idlulileyo, enkosi kwizinto ezintsha kubuchwephesha obutsha obuvumele abenzi bebhodi yesekethe ukuba bavelise ngokuchanekileyo nangobungcali.

Nantsi indlela yokwenza iprototype PCB ngokuchanekileyo.

Ukuphela kokuhlolwa kobunjineli

Ngaphambi kokubonisa i-PCB, zininzi izinto ezinokusetyenziselwa ukucwangcisa iziphumo. Okokuqala, umenzi wePCB uzakufunda ngononophelo kuyilo lwebhodi (uxwebhu lweGerber) kwaye aqale ukulungiselela ibhodi, edwelise imiyalelo yenyathelo nenyathelo ngenyathelo. Emva koqwalaselo, iinjineli ziya kuguqula ezi zicwangciso zibe yifomathi yedatha eya kuthi incede ukuyila i-PCB. Injineli iya kujonga ifomathi yazo naziphi na iingxaki okanye ukucocwa.

Le datha isetyenziselwa ukwenza ibhodi yokugqibela kwaye ibonelele ngenombolo yesixhobo esikhethekileyo. Eli nani lilanda inkqubo yokwakha ye-PCB. Nokuba lolona tshintsho lincinci kuhlaziyo lwebhodi luya kukhokelela kwinombolo yesixhobo esitsha, esinceda ekuqinisekiseni ukuba akukho siphithiphithi ngexesha lePBB kunye nokuveliswa kwezinto ezininzi.

umzobo

Emva kokujonga iifayile ezichanekileyo kunye nokukhetha eyona ndawo ifanelekileyo yepaneli, ukushicilelwa kweefoto kuqala. Esi sisiqalo senkqubo yemveliso. Iifotoplotters zisebenzisa ii-lasers ukuzoba iipateni, izikrini zesilika kunye neminye imifanekiso ephambili kwi-PCB.

Zokulaminetha kunye ukubhola

Olunye lweendidi ezintathu eziphambili zeebhodi zesekethe eziprintiweyo, ezaziwa ngokuba zii-PCBS ezininzi, zifuna i-lamination ukuba ifake iileya kunye. Oku kuhlala kusenziwa kusetyenziswa ubushushu kunye noxinzelelo.

Emva kokulaminetha imveliso, inkqubo yokomba yobungcali iya kucwangciswa ukubhola ngokuchanekileyo nangokuchanekileyo emithini. Inkqubo yokomba iqinisekisa ukuba akukho mpazamo yomntu ngexesha lokuvelisa kwe-PCB.

Ukuhanjiswa kobhedu kunye nesingxobo

Amacwecwe obhedu aqhubayo afakwe yi-electrolysis abalulekile ekusebenzeni kwazo zonke iibhodi zesekethe eziprintiweyo. Emva electroplating, i-PCB ngokusesikweni iba umphezulu conductive nobhedu electroplated kule ndawo ngu electroplating isisombululo. Ezi ngcingo zobhedu ziindlela eziqhubayo ezidibanisa amanqaku amabini ngaphakathi kwePCB.

Emva kokwenza uvavanyo loqinisekiso lomgangatho kwi-PCB yomzekelo, zenziwa zangumda kwaye ekugqibeleni zahlolwa ukucoceka.
