Ma board a FR4 Osindikizidwa amitundu iwiri omwe amaikidwa m'mapiritsi
1. Kugawa mphamvu: Kugawa mphamvu kwa piritsi la PC kumatenga magawo awiri a FR4 PCB.Ma PCB awa amathandizira kuyendetsa bwino kwa mizere yamagetsi kuti awonetsetse kuti ma voliyumu oyenera komanso kugawidwa kumagulu osiyanasiyana a piritsi, kuphatikiza mawonetsero, purosesa, kukumbukira ndi ma module olumikizira.
2. Mayendedwe a Signal: Pawiri-wosanjikiza FR4 PCB imapereka mawaya oyenera ndi njira yotumizira chizindikiro pakati pa zigawo zosiyanasiyana ndi ma modules mu kompyuta ya piritsi.Amalumikiza mabwalo osiyanasiyana ophatikizika (ICs), zolumikizira, masensa, ndi zigawo zina, kuwonetsetsa kulumikizana koyenera komanso kusamutsa deta mkati mwa zida.
3. Kukwera kwa Zigawo: The FR4 PCB yokhala ndi zigawo ziwiri yapangidwa kuti igwirizane ndi kuyika kwa zigawo zosiyanasiyana za Surface Mount Technology (SMT) mu piritsi.Izi zikuphatikiza ma microprocessors, ma module amakumbukidwe, ma capacitors, resistors, mabwalo ophatikizika ndi zolumikizira.Kapangidwe ka PCB ndi kapangidwe kake kumapangitsa kuti pakhale malo oyenera komanso makonzedwe a zigawo kuti ziwongolere magwiridwe antchito ndikuchepetsa kusokoneza kwa ma sign.
4. Kukula ndi compactness: FR4 PCBs amadziwika kuti durability ndi mbiri ndi woonda kwambiri, kuwapanga kukhala oyenera ntchito yaying'ono zipangizo monga mapiritsi.Ma FR4 PCB amitundu iwiri amalola kachulukidwe kazinthu zambiri pamalo ochepa, zomwe zimathandiza opanga kupanga mapiritsi owonda komanso opepuka popanda kusokoneza magwiridwe antchito.
5. Kutsika mtengo: Poyerekeza ndi magawo apamwamba kwambiri a PCB, FR4 ndi zinthu zotsika mtengo.Ma FR4 PCB amitundu iwiri amapereka njira yotsika mtengo kwa opanga mapiritsi omwe amayenera kuchepetsa mtengo wopangira ndikusunga zabwino ndi zodalirika.
Kodi Magulu Awiri Awiri Osindikizidwa a FR4 Amathandizira bwanji magwiridwe antchito a mapiritsi?
1. Ndege zapansi ndi mphamvu: Ma PCB a FR4 osanjikiza awiri amakhala ndi ndege zodzipatulira zapansi ndi mphamvu zothandizira kuchepetsa phokoso ndi kukhathamiritsa kugawa mphamvu.Ndegezi zimagwira ntchito ngati chitsimikiziro chokhazikika cha kukhulupirika kwa chizindikiro ndikuchepetsa kusokoneza pakati pa mabwalo osiyanasiyana ndi zigawo.
2. Njira zowongolera zowongolera: Pofuna kuwonetsetsa kufalikira kwa ma siginecha odalirika ndikuchepetsa kuchepetsedwa kwa ma siginecha, njira yoyendetsedwa ndi impedance imagwiritsidwa ntchito popanga FR4 PCB yamitundu iwiri.Njirazi zimapangidwira mosamala ndi m'lifupi mwake komanso malo otalikirana kuti akwaniritse zofunikira zolepheretsa ma siginecha othamanga kwambiri komanso malo olumikizirana monga USB, HDMI kapena WiFi.
3. Kuteteza kwa EMI/EMC: Pawiri-wosanjikiza FR4 PCB ikhoza kugwiritsa ntchito ukadaulo wotchinga kuti muchepetse kusokoneza kwa electromagnetic (EMI) ndikuwonetsetsa kuyanjana kwamagetsi (EMC).Zigawo zamkuwa kapena zotchinjiriza zitha kuwonjezeredwa ku mapangidwe a PCB kuti alekanitse madera okhudzidwa ndi magwero akunja a EMI ndikuletsa mpweya womwe ungasokoneze zida kapena machitidwe ena.
4. Zoganizira za mapangidwe apamwamba: Pamapiritsi omwe ali ndi zigawo zapamwamba kwambiri kapena ma modules monga kugwirizana kwa ma cellular (LTE / 5G), GPS kapena Bluetooth, mapangidwe a FR4 PCB omwe ali ndi magawo awiri ayenera kuganizira ntchito zapamwamba.Izi zikuphatikiza kufananiza kwa ma impedance, njira zowongolera zolumikizirana komanso njira zoyenera zoyendera ma RF kuti zitsimikizire kukhulupirika kwa ma siginecha komanso kutayika kochepa.
