N’chifukwa chiyani tiyenera kuchita mabowo fan mu PCB kupanga koyamba?

Pali zolinga ziwiri za mabowo a fan, kuti apitirire kuti atenge malo ndikuchepetsa njira yobwerera!

Mwachitsanzo, dzenje la GND, dzenje lapafupi la fan litha kukwaniritsa cholinga chofupikitsa njira!

Cholinga chokhomerera chisanadze ndi kuteteza mabowo kuti asakhomedwe pamene mawaya ali wandiweyani kwambiri pambuyo poti mabowo sanabooledwe. Mzere wa GND umalumikizidwa mtunda wautali, womwe ndi njira yayitali kwambiri yobwerera.

Izi nthawi zambiri zimakumana popanga mapangidwe apamwamba kwambiri a PCB ndi mapangidwe a PCB amitundu yambiri. Ndikwabwino kwambiri kuchotsa dzenje pambuyo chisanadze kukhomerera. M’malo mwake, ndizovuta kwambiri kuwonjezera via mukamaliza kuyendetsa waya. Panthawiyi, lingaliro lanu lachizolowezi ndikungopeza waya woti mulumikize, ndipo simungaganizire za SI ya siginecha. Zogwirizana kwambiri ndi machitidwe okhazikika.

Momwe mungaweruzire omwe ayenera kukhala mabowo a fan?

Onse akhoza kukhala mabowo a fan. Mizere yaifupi imatha kulumikizidwa mwachindunji kumtunda, ndipo mizere yayitali imatha kukhala mabowo ogwirizana. Izi ndizothandiza kwambiri kwa opanga ma PCB pakukonza ndi kuwongolera, ndipo mizere yomwe imatuluka ndi yabwino komanso yokongola.

Global zimakupiza mabowo pamaso PCB masanjidwe

1. Mabowo a fani motsatizana ndi koloko kapena koloko; mawaya amfupi amalumikizidwa mwachindunji.

2. Mwachitsanzo, mukhoza kuyamba kuchokera kumunsi kumanzere kumanzere ndikugwirizanitsa mwachindunji ndi mzere waufupi. Chingwe champhamvu chimakhuthala mwachindunji. VIA-8-16mil.

shift+e kuti mugwire pakati.

3. Kukongola, VIA imagwirizana mmwamba ndi pansi kapena kumanzere ndi kumanja.

4. Crystal oscillator, fyuluta yooneka ngati π. Musakhale ndi pokonza pa kristalo oscillator dera. Zoipa chizindikiro. Kenako gwiritsani ntchito gawo la crystal oscillator.

5. Mphamvu zamagetsi: vcc ndi GND ali ndi nambala yofanana ya vias.

6. Samalani kukhulupirika kwa ndege yapansi pamene mukudutsa mabowo. Payenera kukhala pansi pakati pa vias awiri.
