10 Layer ENIG FR4 Impedance Control PCB
Sei Kudzora Impedance PaPCBs?
Kana chiratidzo chichida imwe impedance kuti ishande nemazvo, inodzorwa impedance inofanirwa kufarirwa.Mune yakakwirira-frequency application, yakazara yemagetsi bhodhi ine inogara impedance yakakosha kuchengetedza data inotapurirwa kubva kuhuori uye kuchengetedza kujeka kwechiratidzo.Iyo yakareba iyo trajectory kana yakakwirira iyo frequency, iyo yakawanda adapta inodiwa.Chero kushaikwa kwekuomarara pane ino nhanho kunogona kuwedzera nguva yekuchinja yemagetsi emagetsi kana maseketi uye kutungamirira kuzvikanganiso zvisingatarisirwi.
Kana iyo chikamu ichiiswa padunhu, iyo impedance isingadzoreki yakaoma kuongorora.Zvikamu zvine maitiro akasiyana ekushivirira zvichienderana nebatch yavo.Mukuwedzera, maitiro avo ari pasi pekuchinja kwekushisa, izvo zvinogona kutungamirira kukukundikana.Muchiitiko ichi, kutsiva chikamu kunogona kuita senge mhinduro pakutanga, asi kutaura zvazviri, kusakodzera trace impedance ndiyo mudzi wedambudziko.
Ichi ndicho chikonzero chetrace impedance uye kushivirira kwayo kunofanirwa kuongororwa kutanga mukatirakadhindwa redunhu bhodhi (PCB)design.Mugadziri anofanira kushanda pamwe chete nemugadziri kuti ave nechokwadi chekuti kukosha kwechikamu kwazadzikiswa.
Impedance maitiro ePCB
PCB yekutevera impedance ine akati wandei maitiro ekudzidza impedance.PCB bhodhi dhizaini impedance inosanganisira: kubvumidzwa, kureba, hupamhi, kureba, PCB yekugadzira miganho / kushivirira, uye hunhu hwechinhambwe pakati pe track nedzimwe mhangura.
Zvikumbiro zveImpedance Control PCB
Impedance control inosanganisira kuyera iyo impedance yedzimwe nzira dzekufambisa panguva yekugadzira bhodhi uye kuve nechokwadi kuti iri mukati memiganho inotaurwa nemugadziri.Iyi nzira inodhura, asi yakave yakagamuchirwa munharaunda kubva pakutanga kwe2000s sezvo kuwanda kwezvinhu zvemagetsi zvinoramba zvichiwedzera.Semuenzaniso, ishandise mune zvinotevera zvigadzirwa:
Analog uye digital telecommunication
Vhidhiyo chiratidzo chekugadzirisa
Internet bhokisi, TV, GPS, vhidhiyo mutambo, digitaalinen kamera
Makomputa, mahwendefa, mafoni
Motor control module
