Seboka sa PCB sa Maqhubu a Phahameng

Shenzhen Cirket Electronics Co., Ltd, tharollo ea hau e le 'ngoe bakeng sa litlhoko tsohle tsa hau tsa OEM le ODM PCB le PCBA. E thehiloe ka 2009, re se re hōlile ho ba mofani ea ka sehloohong oa litšebeletso tse feletseng tsa turnkey bakeng sa bareki lefatšeng ka bophara. Ka mela e 9 ea SMT le mela e 2 ea DIP, re na le bokhoni ba ho sebetsana le karolo e 'ngoe le e 'ngoe ea ts'ebetso ea tlhahiso, ho tloha ho nts'etsopele le ho reka thepa, ho kopanya le ho tsamaisa thepa.


PCB ea maqhubu a phahameng (Printed Circuit Board) e bolela mofuta oa boto ea potoloho e etselitsoeng ho sebetsa ho maqhubu a seea-le-moea (RF) kapa maqhubu a microwave. Maqhubu ana hangata a tloha ho makholo a megahertz (MHz) ho isa ho li-gigahertz tse 'maloa (GHz) 'me a sebelisoa hangata lits'ebetsong tse kang litsamaiso tsa puisano tse se nang mohala, litsamaiso tsa radar, likhokahano tsa sathelaete, le ts'ebetso ea matshwao a dijithale ka lebelo le phahameng.

    Li-PCB tsa maqhubu a phahameng li na le litšobotsi tse 'maloa tse ikhethang le menahano ea moralo ha li bapisoa le li-PCB tse tloaelehileng:

    1. Khetho ea Lintho: Li-PCB tsa maqhubu a phahameng hangata li sebelisa lisebelisoa tse ikhethang tse nang le thepa e ntle ea motlakase ho fokotsa tahlehelo ea matšoao le ho boloka botsitso ba matšoao maemong a holimo. Lisebelisoa tse tloaelehileng li kenyelletsa li-substrates tsa PTFE (Polytetrafluoroethylene) tse kang Teflon, hammoho le li-laminate tse phahameng-frequency tse kang FR-4 tse nang le thepa e matlafalitsoeng ea dielectric.

    2. Tahlehelo e Tlase ea Dielectric:Lisebelisoa tsa dielectric tse sebelisoang ho li-PCB tse phahameng-frequency li khethoa bakeng sa dielectric constant constant (Dk) le low dissipation factor (Df), tse thusang ho fokotsa ho fokotsa matšoao le ho sotha ha maqhubu a phahameng.

    3. Tšitiso e Laolehileng: Li-PCB tse nang le maqhubu a phahameng hangata li hloka taolo e nepahetseng ea ho thibela phetiso ho netefatsa phetiso e nepahetseng ea mats'oao le ho fokotsa likhakanyo. Trace wide, botenya ba dielectric, le litlhophiso tsa layer stackup li entsoe ka hloko ho fihlela sebopeho se lakatsehang.

    4. Ho Beha fatše le ho Sireletsa: Mekhoa e nepahetseng ea ho thea le ho sireletsa e bohlokoa molemong oa moralo oa PCB oa maqhubu a holimo ho fokotsa tšitiso ea motlakase (EMI) le ho netefatsa botšepehi ba matšoao. Lifofane tse ka tlas'a lefatše, mesaletsa ea balebeli le likarolo tse sireletsang li sebelisoa ho fokotsa lipuo le lerata.

    5. Moralo oa Mohala oa Phetiso: Lits'oants'o tsa maqhubu a holimo ho li-PCB li sebetsa joalo ka lithapo tsa phetiso ho fapana le mesaletsa e bonolo ea motlakase. Melao-motheo ea moralo oa phetisetso, joalo ka lithapo tse laoloang tsa impedance, litlhophiso tsa microstrip kapa stripline, le mekhoa ea ho tsamaisana le impedance, li sebelisoa ho ntlafatsa boleng ba matšoao le ho fokotsa ho senyeha ha matšoao.

    6. Ho bea Karolo le Tsela ea ho Tsamaisa:Ho beoa ka hloko le ho tsamaisa likarolo le mesaletsa ea mats'oao ho bohlokoa molemong oa sebopeho sa PCB sa maqhubu a holimo ho fokotsa bolelele ba tsela ea matšoao, ho qoba ho kobeha ho nchocho, le ho fokotsa litlamorao tse ka nyenyefatsang boleng ba matšoao.

    7. Lihokelo tsa Maqhubu a Phahameng:Lihokelo tse sebelisoang ho li-PCB tsa maqhubu a phahameng li khethoa bakeng sa litšobotsi tsa tsona tse tsamaisanang le impedance le tahlehelo e tlase ea ho kenya ho fokotsa lipontšo tsa matšoao le ho boloka botsitso ba matšoao maemong a holimo.

    8. Taolo ea Mocheso: Lits'ebetsong tse ling tsa matla a phahameng a maqhubu a phahameng, taolo ea mocheso e ba ea bohlokoa ho thibela ho chesa haholo ha likarolo le ho boloka ts'ebetso e tšepahalang. Lichelete tsa mocheso, lisebelisoa tsa mocheso, le mekhoa ea tsamaiso ea mocheso li sebelisoa ho felisa mocheso ka katleho.
