Hauv kev tsim khoom ntawmhigh-frequency boards, kub plating thiab immersion kub nto kho txheej txheem. Nws yog feem ntau siv rau hauv kev tsim cov boards ntau zaus, qhov chaw tiv thaiv ntxiv rau saum npoo ntawm tooj liab los tiv thaiv oxidation thiab txhim kho vuam kev ua tau zoo. Muaj ntau cov txheej txheem kho saum npoo rau cov laug cam, suav nrog kub plating, immersion kub, npib tsib xee palladium kub, nyiaj plating, tin spraying, OPS, thiab lwm yam. Ntawm no, peb tsuas yog qhia ob txoj hauv kev tshaj plaws: kub plating thiab immersion kub plating.
Cov txheej txheem kev kho deg rau cov khoom siv ntau zaus: kub plating
Kub plating yog ib txoj hauv kev tso cov txheej kub ntawm cov tooj liab los ntawm cov tshuaj electrochemical. Kub yog cov hlau ruaj khov heev uas tsis oxidize thiab muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv, yog li kub plating tuaj yeem tiv thaiv tooj liab circuits zoo thiab txhim kho kev ua haujlwm thiab kev ua neej ntawm PCBs. Qhov zoo ntawm kub plating yog:
1. Kub plated high-frequency boards tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj xim lossis tsis zoo, ua rau lawv tsim nyog rau kev siv mus ntev lossis khaws cia.
2. Cov kub-plated high-frequency board tuaj yeem tiv taus qhov kub thiab txias yam tsis tau poob los yog deforming, ua rau nws tsim nyog rau cov vuam kub kub lossis kub kub ua haujlwm.
3. Kub plated high-frequency boards tuaj yeem txhim kho cov teeb liab kis tau tus mob zoo, txo cov teeb liab poob thiab cuam tshuam, thiab tsim nyog rau high-frequency, high-speed, thiab high-precision circuits.
Cov txheej txheem kev kho deg rau cov khoom siv ntau zaus: immersion kub
Sinking kub yog ib txoj hauv kev tso ib txheej ntawm kub rau saum npoo ntawm tooj liab los ntawm cov tshuaj tiv thaiv. Qhov sib txawv ntawm immersion kub thiab kub plating yog tias immersion kub tsuas yog tso kub rau ntawm solder ncoo, thaum kub plating yog kub plating rau tag nrho cov Circuit Court. Qhov zoo ntawm sinking kub muaj xws li:
1. Lub Circuit Court ntawm lub rooj tsavxwm high-frequency nrog sunk kub yog du thiab tiaj tus, tsis muaj protrusions los yog depressions, haum rau nto mount technology thiab installation ntawm micro Cheebtsam.
2. Qhov kev ua tau zoo ntawm cov laug cam nrog kub deposition yog qhov zoo vim hais tias cov qauv siv lead ua ntawm cov kub deposition yog finer dua li cov kub plating, ua rau nws yooj yim rau daim ntawv cog lus nrog solder, thiab hardness ntawm kub deposition yog qis dua kub. plating, ua rau nws tsis tshua muaj peev xwm ua rau brittleness hauv cov pob qij txha.
3. Lub teeb liab kis tau tus mob zoo ntawm lub rooj tsavxwm high-frequency nrog sunk kub yog qhov zoo vim tias cov kub kub tsuas yog tso rau ntawm cov ntaub qhwv, uas tsis cuam tshuam rau lub impedance ntawm Circuit Court, thiab lub hnub ci kub kub tsis tsim cov xov hlau kub, txo kev pheej hmoo ntawm kev ua txhaum.
