VGA (Video Graphics Array) uas yog, video graphics array, nrog siab daws teeb meem, ceev zaub tus nqi, nplua nuj xim, thiab lwm yam. VGA interface tsis yog tus qauv interface rau CRT cov khoom siv, tab sis kuj yog tus qauv interface rau LcD kua siv lead ua khoom siv. , nrog ntau yam kev siv.
VGA OUT PCB tsim kev txiav txim siab
1. Lub zuag qhia tag nrho layout, VGA lub rooj kom ze li sai tau mus rau lub conversion nti tso, sim ua kom luv luv VGA analog teeb liab sib dhos.
2. Lub decoupling capacitors ntawm conversion nti fais fab mov yuav tsum tau muab tso rau ze li sai tau rau lub hwj chim mov pins ntawm lub conversion nti.
3. VGA_R/G/B yuav tsum txuas 75ohm rub-down resistor, precision ntawm 1%;resistor yuav tsum tau muab tso rau ze ntawm lub nti.
4. VGA_R / G / B alignment kab dav li tuab li ua tau, nws raug pom zoo tias ntau tshaj 12mil, thiab qhov ntev sib txawv ntawm lawv yuav tsum tsis pub tshaj 200mil.
5. VGA_R / G / B teeb liab yuav tsum tau nyob thoob plaws hauv cov pob ntawv hauv av sib cais, pob ntawv hauv av sib dhos ncua sij hawm ntawm 300mil lossis tsawg dua yuav tsum muaj av hla lub qhov.
6. VGA_R / G / B teeb liab nyob ib sab ntawm txheej yuav tsum yog lub dav hlau hauv av, tsis yog lub dav hlau fais fab.
7. VGA_R/G/B signals nyob deb ntawm LCD, DRAM thiab lwm yam high-ceev teeb liab kab, txwv tsis pub nyob rau hauv lub high-ceev teeb liab kab nyob ib sab ntawm cov txheej txheem;txwv tsis pub nyob rau hauv high-ceev teeb liab kab nyob ze ntawm lub qhov rau txheej;kev sib raug zoo tsis dhau los ntawm cheeb tsam inductive;deb ntawm RF teeb liab thiab cov khoom siv;
8. VGA_HSYNC/VSYNC RC lim yuav tsum muab tso ze rau ntawm lub rooj zaum VGA, qhov kev sib dhos yuav tsum tsis pub tshaj 6 Nti.
9. VGA lub rooj tag nrho cov teeb liab TVS raj yuav tsum muab tso rau ze li sai tau rau lub rooj sib txuas, lub teeb liab topology: VGA lub rooj → TVS → nti pin;ESD tshwm sim, ESD tam sim no yuav tsum xub dhau los ntawm TVS ntaus ntawv attenuation;TVS ntaus ntawv alignment tsis muaj qhov seem seem (Stub);TVS av pins raug pom zoo kom sim ua kom cov av hla lub qhov, tsawg kawg kom ntseeg tau tias ob lub 0.4 * 0.2mm hla lub qhov, txhawm rau ntxiv dag zog rau lub peev xwm electrostatic tawm.Txhim kho lub peev xwm electrostatic tawm.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom.Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Peb ntseeg tias cov neeg zoo thiab cov neeg koom tes ua rau NeoDen yog ib lub tuam txhab zoo thiab tias peb txoj kev cog lus rau Innovation, Diversity thiab Sustainability kom ntseeg tau tias SMT automation yog siv tau rau txhua tus neeg nyiam nyiam nyob txhua qhov chaw.
