Konzani 8 Layer Pcb chizindikiro kukhulupirika ndi mavuto kugawa wotchi

Ngati mumachita nawo zamagetsi ndi ma board osindikizira (PCBs), mwina mwakumana ndi zovuta zofala ndi kukhulupirika kwa ma siginecha ndi kugawa koloko. Nkhanizi zimakhala zovuta kuzithetsa, koma musachite mantha!Mu positi iyi yabulogu, tiwona momwe tingathetsere kukhulupirika kwa ma sign ndi nkhani zogawa mawotchi pa ma PCB 8-wosanjikiza. Kuti tikuthandizeni paulendo wanu, tikudziwitsani Capel, kampani yomwe yachita zaka 15 pakupanga PCB ndikuwongolera mosamalitsa.

Kukhulupirika kwa Signal ndi gawo lofunikira pakupanga kwa PCB chifukwa kumatsimikizira kuti ma siginecha amagetsi omwe amaperekedwa mkati mwa PCB sakuwonongeka kapena kupotozedwa.Pamene nkhani za kukhulupirika kwa chizindikiro zichitika, katangale wa deta, zolakwika za nthawi, ngakhale kulephera kwadongosolo kumachitika. Chifukwa chake, ndikofunikira kuthana ndi zovuta izi.

Kugawa koloko, kumbali ina, kumatanthauza njira yotumizira mawotchi mu PCB yonse.Kugawa kolondola kwa mawotchi ndikofunikira pakulumikizana ndi nthawi mkati mwa makina apakompyuta. Kusakwanira kwa mawotchi kungayambitse zinthu zosiyanasiyana, zomwe zimayambitsa kulephera kwadongosolo kapena kulephera kwathunthu.

Tsopano, tiyeni tilowe munjira zina ndi malangizo othetsera mavutowa:

1. Mapangidwe a stacking: Kuyika mosanjikiza mosamala ndi maziko owonetsetsa kukhulupirika kwa chizindikiro ndi kugawa kwa wotchi. Ma PCB a 8-wosanjikiza amapereka kusinthasintha kwakukulu popanga mphamvu ndi ndege zapansi, kuthandiza kuchepetsa phokoso ndi kupereka kukhulupirika kwa chizindikiro.Ganizirani kugwiritsa ntchito mphamvu zosiyana ndi ndege zapansi pa chizindikiro chilichonse ndikukhazikitsa ndege zodalirika.

2. Kulamulira kwa Impedans: Kusunga kutetezedwa koyendetsedwa mu PCB n'kofunika kwambiri kuti tisonyeze kukhulupirika. Gwiritsani ntchito chida chowerengera cholepheretsa kuti muwone m'lifupi ndi malo ofunikira pa chingwe chotumizira potengera zida za PCB ndi masanjidwe ake.Ndi zaka 15 zopanga PCB, Capel amatha kupereka chitsogozo chaukadaulo ndikuwonetsetsa kuwongolera kolondola kwa impedance.

3. Tekinoloje yoyendetsera njira: Ukadaulo wolondola wanjira umakhala ndi gawo lofunikira pakuthana ndi kukhulupirika kwa chizindikiro ndi nkhani zogawa mawotchi. Kugwiritsa ntchito njira zazifupi kumachepetsa kuchedwa kwa ma siginecha komanso kumachepetsa kulumikizana kwa phokoso.Gwiritsani ntchito ma siginecha osiyanasiyana pazizindikiro zothamanga kwambiri kuti muwonjezere chitetezo chamkokomo. Kuphatikiza apo, njira zofananira zazitali zimagwiritsidwa ntchito kuti zichepetse nthawi komanso kugwirizanitsa.

4. Decoupling capacitors: Kuyika ma capacitor ophatikizira pafupi ndi ma circuit Integrated (ICs) kumathandiza kupondereza phokoso ndikuonetsetsa kuti magetsi azikhala okhazikika panthawi yogwira ntchito kwambiri.Decoupling capacitors amapereka njira yochepetsera pansi, kuchepetsa kusinthasintha kwa magetsi ndikupewa kupotoza kwa chizindikiro.

5. Kuteteza kwa EMI: Kusokoneza kwa Electromagnetic (EMI) kungakhudze kwambiri kukhulupirika kwa chizindikiro ndi kugawa kwa wotchi.Kukhazikitsa njira zotchinjiriza za EMI, monga kugwiritsa ntchito chishango chozikika pansi kapena kuwonjezera zowongolera, kumatha kuchepetsa zotsatira za EMI ndikuwongolera magwiridwe antchito.

Tsopano popeza tafufuza njira zothandiza zowonetsera umphumphu ndi zovuta zogawa mawotchi, tiyeni tidziwitse Capel - kampani yomwe ili ndi chidziwitso chambiri komanso yowongolera bwino pakupanga PCB.Ndi zaka 15 zaukatswiri wamakampani, Capel amamvetsetsa zovuta zamapangidwe a PCB ndipo atha kukupatsani mayankho odalirika pantchito yanu.

Capel akudzipereka kuwongolera bwino kwambiri kuti awonetsetse kuti PCB iliyonse yomwe amapanga ikukwaniritsa miyezo yapamwamba kwambiri.Kuyambira gawo loyambirira la mapangidwe mpaka kupanga komaliza, Capel amagwiritsa ntchito kuyesa mozama ndikuwunika kuti athetse kukhulupirika kwa chizindikiro kapena nkhani zogawa mawotchi. Gulu lawo la mainjiniya odziwa zambiri litha kukupatsani luntha komanso chitsogozo chothandizira kuti polojekiti yanu ya PCB ikhale yopambana.

Mwachidule, kuthetsa kukhulupirika kwa ma siginecha ndi nkhani zogawa mawotchi a PCB yosanjikiza 8 kumafuna kukonzekera bwino, njira zopangira zolondola, komanso ukatswiri woyenera.Kugwiritsa ntchito njira monga kukhathamiritsa masanjidwe, kusungitsa chitetezo chowongolera, kugwiritsa ntchito njira zoyenera, ndikuphatikiza njira zotchinjiriza za EMI zitha kupititsa patsogolo magwiridwe antchito a PCB. Ndi mnzanu wodalirika ngati Capel, mutha kukhala otsimikiza kuti PCB yanu idzapangidwa mwapamwamba kwambiri komanso yolondola. Chifukwa chake, landirani mayankho awa ndikupanga projekiti yanu yotsatira ya PCB kukhala yopambana!
