Nei tichifanira kuita maburi fan mukati PCB kugadzira kutanga?

Pane zvikonzero zviviri zvemaburi e fan, kuti perforate kutora nzvimbo uye kuderedza nzira yekudzoka!

Semuenzaniso, iyo GND gomba, iro riri padyo fan gomba rinogona kuzadzisa chinangwa chekupfupisa nzira!

Chinangwa chepre-punching ndechekudzivirira maburi haakwanise kuroverwa kana wiring yakanyanya kuoma mushure mekunge maburi asina kuroverwa. Mutsara weGND wakabatanidzwa chinhambwe chakareba, inova nzira yakarebesa yekudzoka.

Izvi zvinowanzosangana kana uchiita yakakwirira-kumhanya PCB dhizaini uye akawanda-layer PCB dhizaini. Zviri nyore kudzima gomba mushure mekutanga kubaya. Pane zvinopesana, zvakanyanya kuoma kuwedzera via mushure mekunge wapedza kufambisa waya. Panguva ino, yako yakajairika pfungwa ndeyekungotsvaga waya yekuibatanidza, uye haugone kufunga nezve SI yechiratidzo. Zvakanyanya kuenderana nemaitiro enormative.

Nzira yekutonga sei avo vanofanira kunge vari maburi e fan?

Ose anogona kunge ari maburi e fan. Mitsetse mipfupi inogona kubatanidzwa zvakananga kune iyo yepamusoro layer, uye mitsetse yakareba inogona kubatanidzwa maburi fan. Izvi zvinobatsira zvikuru kuvagadziri vePCB mukuronga nekufambisa, uye mitsetse inobuda yakachena uye yakanaka.

Global fan maburi pamberi pePCB dhizaini

1. Maburi e fan counterclockwise kana clockwise; waya pfupi dzakabatanidzwa zvakananga.

2. Semuenzaniso, unogona kutanga kubva kumucheto wezasi kuruboshwe uye unobatanidza zvakananga nemutsara mupfupi. Tambo yemagetsi yakanyatsokobvu. VIA-8-16mil.

shift+e kubata pakati.

3. Nokuda kwerunako, VIA yakarongedzwa kumusoro uye pasi kana kuruboshwe uye kurudyi.

4. Crystal oscillator, π-shaped sefa. Usave nekugadzirisa pane crystal oscillator circuit. Zvakaipa pachiratidzo. Wobva wabata nekristaro oscillator wedunhu.

5. Simba rekushandisa: vcc neGND vane nhamba imwechete yevias.

6. Ngwarira kuvimbika kwendege yepasi paunenge uchipfuura nemakomba. Panofanira kuva pasi pakati vias maviri.
