Qhov sib txawv ntawm electroplating thiab resin qhov-plug hauv PCB ua

PCB qhov-plugged feem ntau yog siv rau txheej thib ob ntawm tus number case (cov roj ntsuab) tom qab lub npog ntsej muag lub ntsej muag los sau cov cua kub dissipation qhov (Termal ncoo) nrog lub aperture tsawg dua 0.55mm. Lub hom phiaj ntawm lub qhov ntsaws rau hauv PCB ua yog kom tsis txhob luv luv Circuit Court los ntawm tin nkag mus rau hauv cov txheej txheem ntawm kev dhau los ntawm lub cub tawg, tshwj xeeb tshaj yog nyob rau hauv BGA tsim, tuav lub nto flatness, ua tau raws li cov neeg muas zaub impedance yuav tsum tau, thiab zam cov kab teeb liab puas thaum DIP yog. siv rau qhov chaw.

Dab tsi yog qhov txawv ntawm electroplating thiab resin qhov ntsaws?

① Txawv nto

Electroplating qhov-plugged yog sau los ntawm lub qhov los ntawm tooj liab plating, thiab qhov saum npoo ntawm lub qhov yog tag nrho ntawm cov hlau, thaum resin qhov-plugged yog sau los ntawm lub qhov phab ntsa nrog epoxy resin tom qab tooj liab plating, thiab thaum kawg tooj liab plating ntawm lub qhov. resin nto. Cov nyhuv yog tias lub qhov tuaj yeem ua tau zoo, thiab qhov chaw tsis muaj dents, uas tsis cuam tshuam rau vuam.

② Cov txheej txheem ntau lawm

Electroplating qhov-plugged yog sau los ntawm lub qhov ncaj qha los ntawm electroplating yam tsis muaj qhov sib txawv. Tom qab lub qhov phab ntsa yog tooj liab-plated, cov resin qhov-plugged yog sau nrog epoxy resin sau lub qhov, thiab thaum kawg lub nto yog tooj liab-plated.

③ Cov nqi sib txawv

Cov oxidation tsis kam ntawm electroplating yog qhov zoo, tab sis cov txheej txheem yuav tsum siab thiab tus nqi yog kim. Cov resin muaj rwb thaiv tsev zoo thiab pheej yig.
