Khetho ea Lisebelisoa bakeng sa Li-PCB tsa Ultrasound tsa Sehlopha sa Bongaka
Mekhoa ea ho nka litšoantšo ea ultrasound e hloka phetiso ea matšoao e nepahetseng haholo, e nang le maqhubu a phahameng, botšepehi, le ho lumellana ha lintho tse phelang. Motheong oa mekhoa ena ho na le PCB, 'me ho khetha thepa e nepahetseng ho bohlokoa ho netefatsa polokeho, ho nepahala le ts'ebetso ea nako e telele lits'ebetsong tsa bongaka.
Ke Hobane'ng ha Khetho ea Lintho e le ea Bohlokoa ho Li-PCB tsa Ultrasound tsa Bongaka?
Litšebelisong tsa maemo a bongaka, haholo-holo litšoantšo tsa tlhahlobo, li-PCB li tlameha ho:
- Tšehetsa phetiso ea lets'oao la maqhubu a phahameng (hangata 20–100 MHz)
- Netefatsa botsitso ba mocheso le tahlehelo e tlase ea lets'oao
- E lumellane le lintho tse lumellanang le 'mele kapa tse se nang chefo
- Boloka botsitso ba boholo nakong ea ho bolaea likokoana-hloko
- E fana ka ts'epo e phahameng lisebelisoa tse nyane tsa bongaka
Lisebelisoa tse Sebelisoang Hangata bakeng sa Li-PCB tsa Ultrasound tsa Bongaka
1. Li-Laminate tse nang le maqhubu a mangata
- Lisebelisoa: Rogers RO4350B, Taconic RF-35
- Likarolo: Tahlehelo e tlase ea dielectric (Df), kamehla ea dielectric e tsitsitseng (Dk)
- Kopo: Lera la matšoao ka har'a mapolanka a mokhanni oa transducer
2. FR-4 e nang le Tg e Ntlafalitsoeng
- Lisebelisoa: FR-4 Tg170+, S1000-2M
- Likarolo: Tshebetso e ntle ea mocheso, e theko e tlaase
- Kopo: Di-module tsa motlakase, diboto tsa taolo
3. Polyimide bakeng sa Dipotoloho tse Flex
- Likarolo: Ho tenyetseha ho hoholo, ho hanyetsa mocheso hantle
- Tšebeliso: Likhokahano tsa probe, lisebelisoa tsa ultrasound tse aparoang
4. Dikarolwana tsa letsopa
- Lisebelisoa: Al₂O₃ (alumina), AlN (aluminium nitride)
- Likarolo: Ho tsamaisa mocheso ka mokhoa o ikhethang, ho sebelisoa bakeng sa meralo e menyenyane ea matla a phahameng
- Kopo: Lipheletso tse ka pele tsa tlhahlobo ea ultrasound ea maemo a holimo
Lintlha tsa Bohlokoa tsa Moralo
- Taolo e sa Feleng ea Dielectric: Bohlokoa bakeng sa ho boloka lebelo la lets'oao le ho bapisa impedance
- Tahlehelo ea Tahlehelo (Df): Df e ka tlase e netefatsa ho hlaka ha lets'oao le betere le ho sotha ho tlase
- Ho Monya Mongobo: Lisebelisoa tse nang le mongobo o tlase li hanela ho senyeha ha li-sterilization
- Ho Latela Melao ea RoHS le Biocompatibility: E tlameha ho fihlela melao ea bongaka e kang RoHS, REACH, le litekanyetso tse amanang le FDA
Ho kgetha thepa e nepahetseng ya PCB bakeng sa disebediswa tsa ultrasound tsa maemo a bongaka ho feta qeto ya boenjiniere feela—ke taba ya polokeho ya mokuli le ho nepahala ha bongaka. Ho sebelisana le moetsi wa PCB ya nang le boiphihlelo ya tsebang maemo a bongaka ho netefatsa hore sehlahiswa sa hao se fihlela ditlhoko tsa taolo le tsa tshebetso.
