Iinkcukacha zeMveliso

Iintsilelo zeemfama ezingcwatywa ngePCB

Eyona ngxaki iphambili yokungcwatywa kweemfama ngePCB ziindleko eziphezulu.Ngokwahlukileyo, imingxuma engcwatyiweyo ixabisa ngaphantsi kwemingxuma eyimfama, kodwa ukusetyenziswa kwezi ntlobo zombini zemingxuma kunokunyusa kakhulu ixabiso lebhodi.Ukunyuka kweendleko kubangelwa inkqubo yokuvelisa eyinkimbinkimbi yomgodi oyimfama ongcwatywe, oko kukuthi, ukwanda kweenkqubo zokuvelisa nako kukhokelela ekwandeni kweenkqubo zokuvavanya nokuhlola.

Wangcwatywa ngePCB

Ukungcwatywa ngokusebenzisa ii-PCBs zisetyenziselwa ukudibanisa iileya ezahlukeneyo zangaphakathi, kodwa azinanxibelelwano kunye ne-eutermost layer.Ifayile yoqheliso eyahlukileyo kufuneka yenziwe kwinqanaba ngalinye lomngxuma ongcwatywe.Umlinganiselo wobunzulu bomngxuma ukuya kwindawo yokuvula (inkalo yomlinganiselo/yobutyeba-idayamitha) kufuneka ibe ngaphantsi okanye ilingane no-12.

I-keyhole inquma ubunzulu bomngxuma wesitshixo, umgama ophezulu phakathi kweengqimba zangaphakathi ezahlukeneyo.Ngokubanzi, inkulu indandatho yangaphakathi yomngxuma, uxhulumaniso oluzinzile kwaye oluthembekileyo.

Iimfama Zangcwatywa NgePCB

A: ndingcwatywe nge

B: Yangcwatywa ngelamyini (ayikhuthazwa)

C: Umnqamlezo ungcwatywe ngendlela

Inzuzo yeVias eyimfama kunye nokungcwatywa kweVias yeenjineli kukwanda koxinaniso lwecandelo ngaphandle kokunyuka kwenani lomaleko kunye nobungakanani bebhodi yesekethe.Kwiimveliso ze-elektroniki ezinendawo emxinwa kunye nokunyamezelana koyilo oluncinci, uyilo lomgodi oyimfama lukhetho oluhle.Ukusetyenziswa kwemingxuma enjalo kunceda injineli yoyilo lwesekethe ukuba iyile umngxuma ofanelekileyo / umlinganiselo wephedi ukunqanda umlinganiselo ogqithisileyo.
