Tixgelinta Naqshadeynta VGA OUT PCB

VGA (Video Graphics Array) taas oo ah, sawiro muuqaal ah oo muuqaal ah, oo leh xallin sare, heerka soo bandhigida degdega ah, midabyo qani ah, iwm. , oo leh codsiyo kala duwan.

VGA OUT PCB tixgalinta naqshadeynta

1. Qaabka guud, kursiga VGA sida ugu dhow ee suurtogalka ah ee jajabka beddelka ee la dhigay, isku day in aad soo gaabin toosinta calaamadaha analogga ee VGA.

2. Capacitors decoupling of chip-beddelka korontada waxay u baahan yihiin in la dhigo sida ugu dhow ee suurtogalka ah biinanka korontada ee chip-beddelka.

3. VGA_R/G/B waxay u baahan tahay inay ku xidho iska caabin 75ohm ah oo hoos u soo jiidaya, sax ah 1%;resistor waa in la dhigaa meel u dhow chip-ka.

4. VGA_R / G / B line line width sida qaro weyn sida ugu macquulsan, waxaa lagu talinayaa in ka badan 12mil, iyo dhererka farqiga u dhexeeya iyaga waa in aan ka badan 200mil.

5. Shuruudaha calaamada VGA_R/G/B inta lagu guda jiro habaynta baakidhka dhulka ee kala duwan, baakidhka isku xidhka dhulka ee u dhexeeya 300mil ama ka yar waa inay lahaadaan dhul ka sarreeya godka.

6. Calaamada VGA_R/G/B ee ku dheggan lakabka waa in ay ahaataa diyaarada dhulka ee ma aha diyaarada korontada.

7. Calaamadaha VGA_R/G/B waxay ka fog yihiin LCD, DRAM iyo xariiqyada signallada kale ee xawaaraha sare leh, oo laga mamnuucay xadhkaha signalada xawaaraha sare ee ku dheggan isku xidhka lakabka;Mamnuuc xariiqda calaamadda xawaaraha sare ee u dhow daloolka lakabka;toosintu ma dhaafto gobolka inductive;Ka fogow calaamadaha RF iyo aaladaha;

8. shaandhada VGA_HSYNC/VSYNC RC waa in la dhigaa meel u dhaw kursiga VGA, toosintuna waa in aanu dhaafin 6 Inj.

9. Kursiga VGA ee dhammaan calaamadaha tuubada TVS waa in lagu dhejiyaa sida ugu macquulsan kursiga isku xirka, topology-ga calaamadaha: Kursiga VGA → TVS → pin chip;Ifafaalaha ESD, hadda ESD waa in uu marka hore soo maraa yaraynta aaladda TVS;Isku-xidhka aaladaha TVS ma laha kurti hadhaaga ah (Stub);Biinanka dhulka TVS waxaa lagula talinayaa in ay isku dayaan in ay kordhiyaan dhulka ka badan daloolka, ugu yaraan si loo hubiyo in labada 0.4 * 0.2mm ka badan daloolka, si loo xoojiyo awoodda dheecaanka electrostatic.Xooji awoodda dheecaanka elektrostatic.

Zhejiang NeoDen Technology Co., LTD., oo la aasaasay 2010, waa soo-saare xirfad leh oo ku takhasusay SMT pick and place machine, foornada dib u soo celinta, mashiinka daabacaadda stencil, line-soo-saarka SMT iyo Alaabooyinka kale ee SMT.Waxaan leenahay kooxdayada R & D iyo warshad u gaar ah, anagoo ka faa'iidaysanayna R&D qani ah oo noo gaar ah, wax soo saarka si fiican u tababaran, kasbadeen sumcad weyn macaamiisha adduunka oo dhan.

Waxaan aaminsanahay in dadka waaweyn iyo la-hawlgalayaasheeda ay NeoDen ka dhigaan shirkad weyn iyo in ballanqaadkeenna hal-abuurnimo, Kala duwanaanshiyaha iyo Joogteynta ay hubiso in Automation-ka SMT uu heli karo qof kasta oo xiiseeya meel kasta.
