12-papa-PCB

Hōʻike Pōkole:


ʻIke kikoʻī

Kekahi hou aku ʻikepili no kēia PCB he 12 mau papa

Nā Papa Papa: 12 mau papa

Pau ka mānoanoa o ka papa: 1.6mm

ʻIlikai lapaʻau: ENIG 1 ~ 2 u ”

Nā Pono Papa: Shengyi S1000

Hoʻopau i ka mānoanoa keleawe: 1 OZ papa o loko, 1 OZ pae mai

Waihona Soldmask: Green

Waiho Silkscreen: Keʻokeʻo

Me ka Impedance Control

Nā vias makapō & kanu

12-layers-PCB (3)

He aha nā kumumanaʻo maʻamau o ka impedance a me nā manaʻo hoʻolālā stack no nā papa multilayer?

Ke hoʻolālā ʻana i ka impedance a me ka stacking, ka mea nui

ke kumu o ka mānoanoa PCB, ka helu o nā papa, impedance

 nā koina waiwai, ka nui o kēia manawa, ka pono o ka hōʻailona,

pono pono, a me nā mea ʻē aʻe

penei:

1. He symmetry ka lamineka;

2. He hoʻomau ka Impedance;

3. ʻO ka papa kuhikuhi ma lalo o ka ʻili e pono ai kahi honua piha a i ʻole ke kumu mana (ʻo ka maʻa mau ka papa ʻelua a i ʻole ka penultimate layer);

4. Hoʻopili paʻa ʻia ka mokulele uila a me ka mokulele honua;

5. ʻO ka papa hōʻailona kokoke loa i ka papa mokulele kūmole;

6. E mālama i ka mamao ma waena o ʻelua mau papa hōʻailona pili e like me ka nui i hiki. ʻO orthogonal ke ala ʻana;

7. ʻO nā papa kuhikuhi ʻelua ma luna a ma lalo o ka hōʻailona ka honua a me ka mana, e hoʻāʻo e hoʻopōkole i ka mamao ma waena o ka papa hōʻailona a me ka papa honua;

8. Hoʻokaʻawale hōʻailona hōʻailona ≤ 2 mau manawa i ka laulā o ka laina;

9. ʻO ka prepreg ma waena o nā papa ≤3;

10. Ma ka liʻiliʻi hoʻokahi palapala o 7628 a i ʻole 2116 a i ʻole 3313 i ka papa o waho ʻelua.

11. ʻO ke kaʻina hana o ka prepreg 7628 → 2116 → 3313 → 1080 → 106
