12-zigawo-PCB

Kufotokozera Kwachidule:


Mankhwala Mwatsatanetsatane

Zina zambiri zambiri izi PCB 12 zigawo

Matawa A board: zigawo 12

Kumaliza bolodi makulidwe: 1.6mm

Chithandizo Pamwamba: ENIG 1 ~ 2 u ”

Board Zofunika: Shengyi S1000

Malizitsani makulidwe amkuwa: 1 OZ wosanjikiza wamkati, 1 OZ wosanjikiza

Soldmask Mtundu: Wobiriwira

Mtundu wa Silkscreen: Woyera

Ndi Impedance Control

Akhungu & oyikidwa m'manda

12-layers-PCB (3)

Kodi ndi mfundo ziti zamayendedwe am'mbali ndi masanjidwe amitundu yama board angapo?

Mukamapanga impedance ndi stacking, main

maziko ndi makulidwe a PCB, kuchuluka kwa zigawo, impedance

 zofunika pamtengo, kukula pakali pano, kuwonetsa chizindikiro,

kukhulupirika kwa mphamvu, ndi zina zambiri

ndi awa:

1. Laminate imakhala yofanana;

2. Impedance ili ndi kupitiriza;

3. Malo osanjikiza omwe ali pansi pazipindazo ayenera kukhala malo athunthu kapena magetsi (nthawi zambiri gawo lachiwiri kapena gawo loyambirira);

4. Ndege zamagetsi ndi ndege zapansi zimalumikizidwa mwamphamvu;

5. Chizindikiro chachizindikiro chimayandikira kwambiri kosanjikiza ndege;

6. Sungani mtunda pakati pa zigawo ziwiri zoyandikana zikuluzikulu momwe zingathere. Kuyendetsa ndi orthogonal;

7. Magawo awiri ofotokozera pamwambapa ndi pansi pa chizindikirocho ndi apansi ndi mphamvu, yesetsani kufupikitsa mtunda wapakati pazizindikiro zosanjikiza ndi zosanjikiza pansi;

8. Kusiyanitsa kwa ma siginali times 2 m'lifupi mwake;

9. Kukonzekera pakati pa zigawo ndi ≤3;

10. Pepala limodzi la 7628 kapena 2116 kapena 3313 m'gawo lachiwiri lakunja;

11. Dongosolo logwiritsa ntchito prepreg ndi 7628 → 2116 → 3313 → 1080 → 106
