Dab tsi yog qhov txawv ntawm electroplated plug qhov thiab resin plug qhov hauv PCB boards?
Electroplated plug qhov yog ntim nrog tooj liab plating los ntawm lub qhov, thiab qhov saum npoo ntawm lub qhov yog tag nrho cov hlau. Lub qhov ntsaws lub qhov yog ua tiav los ntawm plating tooj liab rau ntawm phab ntsa ntawm lub qhov-qhov, ces sau nws nrog epoxy resin, thiab thaum kawg plating tooj liab rau ntawm qhov chaw ntawm cov resin. Cov nyhuv yog tias lub qhov tuaj yeem ua tau zoo thiab tsis muaj qhov dents ntawm qhov chaw, uas tsis cuam tshuam rau vuam.
Electroplated plug qhov yog qhov uas tau sau ncaj qha los ntawm electroplating yam tsis muaj qhov khoob, uas yog qhov zoo rau kev vuam, tab sis yuav tsum muaj peev xwm ua tau zoo, uas feem ntau tsis tuaj yeem ua tau rau cov tuam txhab. Resin plug qhov yog hais txog cov txheej txheem ntawm kev sau lub qhov los ntawm lub qhov nrog epoxy resin tom qab tooj liab plating ntawm lub qhov phab ntsa, thiab thaum kawg tooj liab plating rau ntawm qhov chaw. Cov nyhuv zoo ib yam li tsis muaj qhov, uas yog qhov zoo rau kev vuam.
Electroplating muaj qhov zoo oxidation tsis kam, tab sis cov txheej txheem yuav tsum siab thiab tus nqi yog kim; Cov rwb thaiv tsev ntawm cov resin yog qhov zoo thiab tus nqi pheej yig.
Cov txheej txheem HDI laser qhov muag tsis pom cov txheej txheem ntsib cov teeb meem hauv qab no:
Muaj cov voids hauv qhov muag tsis pom ntawm SBU txheej, uas tuaj yeem khaws cua thiab cuam tshuam kev ntseeg tau tom qab thermal shock. Txoj hauv kev los daws qhov teeb meem no yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws. Txawm li cas los xij, kev ntseeg siab ntawm PCB boards tsim los ntawm ob txoj hauv kev no yog qhov nyuaj rau lav thiab cov khoom siv tau qis. Txhawm rau txhim kho cov txheej txheem muaj peev xwm thiab cov txheej txheem HDI, cov txheej txheem electroplating qhov muag tsis pom qhov filling yog siv. Nws qhov zoo dua yog tias qhov qhov muag tsis pom kev tuaj yeem sau nrog electroplated tooj liab, txhim kho kev ntseeg tau zoo. Nyob rau tib lub sijhawm, vim lub tiaj tus thiab tsis concave nto ntawm lub rooj tsavxwm electroplated, cov duab hluav taws xob tuaj yeem ua rau ntawm nws lossis qhov qhov muag tsis pom kev tuaj yeem raug teeb tsa, zoo heev txhim kho cov txheej txheem muaj peev xwm hloov mus rau qhov kev tsim kho thiab hloov tau yooj yim ntawm cov neeg siv khoom.

Electroplating muaj qhov zoo oxidation tsis kam, tab sis cov txheej txheem yuav tsum siab, tus nqi yog kim, thiab cov rwb thaiv tsev resin zoo.
Cov txheej txheem ntawm kev siv resin plug qhov nyob rau hauv PCB feem ntau yog vim BGA qhov chaw, raws li ib txwm BGA yuav ua rau VIA ntawm PAD thiab PAD mus rau sab nraum qab rau thaiv. Txawm li cas los xij, yog tias BGA ntom dhau thiab VIA tsis tuaj yeem tawm mus, nws tuaj yeem ncaj qha drilled los ntawm PAD kom VIA mus rau lwm txheej rau kev xaim, thiab tom qab ntawd cov qhov tuaj yeem ntim nrog cov resin thiab plated nrog tooj liab los ua PAD. Qhov no feem ntau hu ua txheej txheem VIP (ntawm hauv ncoo). Yog tias tsuas yog VIA yog tsim los ntawm PAD yam tsis muaj qhov ntsaws ntsaws qhov, nws yooj yim ua rau tin to, luv luv rau sab nraub qaum, thiab khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
