Impande ebyiri pcb ikibaho prototype FR4 TG140 impedance yagenzuwe PCB

Ikibaho cyumuzunguruko gifite inzitizi yagenzuwe gifite ibintu bikurikira:

1. Kugenzura byimazeyo inzira yo gukora ikibaho cyumuzunguruko, harimo guhitamo ibikoresho, insinga zacapwe, intera igaragara, nibindi, kugirango umenye neza ko inzitizi zihamye;

2. Koresha ibikoresho byihariye byo gushushanya PCB kugirango umenye neza ko impedance yujuje ibisabwa;

3. Muri PCB yose uko yakabaye no kuyikoresha, koresha inzira ngufi kandi ugabanye kunama kugirango umenye neza ko inzitizi ihagaze;

4. Kugabanya imipaka hagati yumurongo wikimenyetso n'umurongo w'amashanyarazi n'umurongo w'ubutaka, kandi ugabanye umuhanda no kwivanga k'umurongo w'ikimenyetso;

5. Koresha tekinoroji ihuye na tekinoroji yihuta yohereza umurongo kugirango wizere neza kandi neza;

6. Koresha tekinoroji ihuza imiyoboro kugirango ugabanye urusaku hamwe nimirasire ya electroniki;

7. Ukurikije ibisabwa bitandukanye byingutu, hitamo uburebure bukwiye, ubugari bwumurongo, intera yumurongo hamwe na dielectric ihoraho;

8. Koresha igikoresho cyihariye cyo gukora ikizamini cya impedance ku kibaho cyumuzenguruko kugirango umenye neza ko ibipimo byinjira byujuje ibisabwa.

Kuki kugenzura inzitizi zisanzwe zishobora gutandukana 10% gusa?

Inshuti nyinshi zirizera rwose ko impedance ishobora kugenzurwa kugeza 5%, ndetse numvise no kubisabwa 2.5%.Mubyukuri, gahunda yo kugenzura impedance ni 10% gutandukana, birenze gato, birashobora kugera kuri 8%, hariho impamvu nyinshi:

1, gutandukana kwibikoresho bya plaque ubwabyo

2. Gutandukana gutandukana mugihe cyo gutunganya PCB

3. Iation yumuvuduko watewe no kumurika mugihe cyo gutunganya PCB

4. Ku muvuduko mwinshi, hejuru yubutaka bwumuringa wumuringa, ingaruka ya fibre fibre ya PP, ningaruka za DF inshuro zitandukanye zamakuru zigomba kumva inzitizi.

Nihehe mbaho ​​zumuzunguruko zisabwa impedance zikoreshwa muri rusange?

Ikibaho cyumuzingi hamwe nibisabwa byangiritse mubisanzwe bikoreshwa mugukwirakwiza ibimenyetso byihuse, nko kohereza ibyuma byihuta byihuta, gukwirakwiza radiyo yumurongo wa radiyo hamwe no gukwirakwiza ibimenyetso bya milimetero.Ibi ni ukubera ko impedance yinama yumuzunguruko ifitanye isano no kwihuta kwihuta no guhagarara kwikimenyetso.Niba igishushanyo mbonera kidafite ishingiro, bizagira ingaruka ku ihererekanyabubasha ryikimenyetso ndetse bitume gutakaza ibimenyetso.Kubwibyo, mubihe bisaba ubwiza bwogukwirakwiza ibimenyetso, mubisanzwe birakenewe gukoresha imbaho ​​zumuzunguruko zisabwa inzitizi.
