Inkqubo ye-etch yeBhodi ye-PCB, esebenzisa iinkqubo zokuthabatha zemveli zokulungisa iindawo ezingakhuselekanga. Uhlobo lokufana nokumba umsele, osebenzayo kodwa ungabi nendlela engabi nayo.

Kwinkqubo yokuphumelela, ikwahlulwe yayinkqubo yefilimu elungileyo kunye nenkqubo yefilimu engalunganga. Inkqubo yefilimu elungileyo isebenzisa i-tin emiselweyo ukukhusela isekethe, kwaye inkqubo yefilimu engalunganga isebenzisa ifilimu eyomileyo okanye ifilimu emanzi ukukhusela isekethe. Imiphetho yemigca okanye iipads ziyi-misshapen ngesikoi-etchingIindlela. Ngalo lonke ixesha umgca wonyuswe yi-0.025mmm, umphetho uya kutyumka kwinqanaba elithile. Ukuqinisekisa ukuba indawo eyaneleyo, umsantsa owocingo uhlala ulinganiswa kwindawo ekufutshane ye-wire nganye ebekiweyo.

Kuthatha ixesha elingakumbi lokukhosela i-ouncer yobhedu ukuze wenze umsantsa omkhulu kwi-wire ye-wire. Oku kubizwa ngokuba yi-ETCK, kwaye ngaphandle komenzi obonelela ngoluhlu olucacileyo lwezithuba ezimbalwa ze-oyile nganye yobhedu, funda umthombo we-etch yomenzi. Kubaluleke kakhulu ukubala ubuncinci bomthamo ngamnye we-over yobhedu. I-ETK ye-ETK ichaphazela umngxunya womthengisi. Ubungakanani be-ring ye-ring yi-0.076mmm icinga + i-0.0762mm ye-trilling + i-0.0762 i-0.0762 i-staking, i-0.2286. I-ETK, okanye into ye-etch, yenye yamagama amane achaza inqanaba lenkqubo.

Ukwenzela ukuthintela umaleko okhuselayo ukuba ungayi kudibana kwaye uhlangabezane neemfuno zokuhamba kwenkqubo yekhemikhali, i-etching yendabuko echaza ukuba ubuncinci bendawo ephakathi kwe-wires ingaphantsi kwe-0.127mm. Ukujonga izinto ezingaphambili zokuvela kwangaphakathi kunye nokuvavanywa ngexesha lenkqubo ye-etch, ububanzi becingo kufuneka lukhulu. Eli xabiso limiselwa bubukhulu bomaleko ofanayo. Umthubi wobhedu, intwana ethatha i-etch yobhedu phakathi kweengcingo kwaye phantsi kokukhusela okukhuselekileyo. Ngasentla, kukho idatha emibini ekufuneka ithathelwe ingqalelo ye-etchical yekhemikhali: Inqaku le-ETK-inani lobhedu lwe-oyile nganye kwi-ounce nganye; kunye nobuncinci be-guck okanye ububanzi be-paille nganye ye-over yobhedu.
