Ukucwenga kwePCB kuneendlela ezininzi
Kukho iindlela ezine eziphambili ze-electroplating kwiibhodi zesekethe: i-electroplating yomgca weminwe, i-electroplating ye-hole, i-reel-linked selective plating, kunye ne-brush plating. Nantsi intshayelelo emfutshane: 01 Ukufakwa kukrozo lweminwe Iintsimbi eziRare kufuneka zibekwe kwibhodi yeziqhagamshelo zomphetho, ibhodi...Funda ngokugqithisileyo -
Ufunde ngokukhawuleza uyilo lwePCB olunemilo engaqhelekanga
I-PCB epheleleyo esiyibonayo idla ngokumila kuxande. Nangona uninzi loyilo lwenene luxande, uyilo oluninzi lufuna iibhodi zeesekethe ezinokwakheka ngokungaqhelekanga, kwaye iimilo ezinjalo zihlala zingabilula ukuyila. Eli nqaku lichaza indlela yokuyila ii-PCB ezimile ngendlela engaqhelekanga. Namhlanje, ubukhulu be ...Funda ngokugqithisileyo -
Ngomngxuma, umngxuma oyimfama, umngxuma ongcwatywe, zithini iimpawu zokomba wePCB ezintathu?
Nge-Via (VIA), lo ngumgodi oqhelekileyo osetyenziselwa ukuqhuba okanye ukudibanisa imigca yefoyile yobhedu phakathi kweepatheni zokuqhuba kwiindlela ezahlukeneyo zebhodi yesekethe. Umzekelo (njengemingxuma eyimfama, imingxuma engcwatyiweyo), kodwa ayikwazi ukufaka icandelo elikhokelela okanye imingxuma yobhedu yezinye izinto eziqinisiweyo.
