8 Txheej ENIG FR4 Via-In-Pad PCB
Qhov nyuaj tshaj plaws los tswj lub qhov ntsaws ntawm lub vias-hauv-pad yog lub pob solder lossis lub ncoo ntawm tus number case hauv lub qhov.Vim yog qhov tsim nyog ntawm kev siv cov khoom siv siab BGA (pob kab sib chaws array) thiab cov miniaturization ntawm SMD nti, daim ntawv thov hauv lub tais qhov tshuab yog ntau thiab ntau dua.Los ntawm kev txhim khu kev qha los ntawm lub qhov ntim cov txheej txheem, lub phaj qhov tshuab tuaj yeem siv rau kev tsim thiab tsim khoom ntawm high-density multilayer board, thiab zam qhov txawv txav.HUIHE Circuits tau siv cov thev naus laus zis hauv-hauv-pad rau ntau xyoo, thiab muaj cov txheej txheem ntau lawm thiab txhim khu kev qha.

Function ntawm Plug Qhov
1. Tiv thaiv cov tin kom dhau los ntawm lub qhov conduction los ntawm cov khoom nto thaum lub sij hawm yoj soldering
2. Zam tsis txhob muaj cov dej ntws tawm hauv lub qhov
3. Tiv thaiv cov pob tin los ntawm popping tawm thaum lub sij hawm yoj soldering, ua rau luv luv Circuit Court
4. Tiv thaiv kom tsis txhob muaj cov nplaum nplaum nplaum los ntawm ntws mus rau hauv lub qhov, ua rau cov vuam virtual thiab cuam tshuam rau qhov haum.
Qhov zoo ntawm Via-In-Pad PCB
1. Txhim kho cua sov dissipation
2.Qhov voltage withstand peev ntawm vias yog txhim kho
3.Muab ib qho chaw tiaj tus thiab zoo ib yam
4.Lower parasitic inductance
Peb Qhov Zoo
1. Tus kheej lub Hoobkas, Hoobkas cheeb tsam 12000 square meters, Hoobkas ncaj muag muag
2. Pab pawg ua lag luam muab kev pabcuam sai thiab zoo ua ntej muag thiab kev pabcuam tomqab muag
3.Process-based processing ntawm PCB tsim cov ntaub ntawv los xyuas kom meej tias cov neeg siv khoom tuaj yeem tshuaj xyuas thiab paub meej hauv thawj zaug
