Koho Mea Hana no nā PCB Ultrasound Papa Lapaʻau

Koi nā ʻōnaehana kiʻi ultrasound i ka hoʻoili hōʻailona pololei kiʻekiʻe, alapine kiʻekiʻe, hilinaʻi, a me ka biocompatibility. Aia ma ka puʻuwai o kēia mau ʻōnaehana ka PCB, a ʻo ke koho ʻana i nā mea kūpono he mea nui ia e hōʻoia i ka palekana, ka pololei, a me ka hana lōʻihi i nā noi lapaʻau.

No ke aha he mea nui ke koho ʻana i nā mea i nā PCB Ultrasound Lapaʻau?

Ma nā noi papa lapaʻau, ʻoiai ke kiʻi diagnostic, pono nā PCB:

• Kākoʻo i ka hoʻoili ʻana o nā hōʻailona alapine kiʻekiʻe (maʻamau 20-100 MHz)
• E hōʻoia i ke kūpaʻa wela a me ka nalowale hōʻailona haʻahaʻa
• E kūlike me nā mea biocompatible a i ʻole nā ​​​​mea ʻawahia ʻole
• E mālama i ke kūpaʻa o ka dimensional i ka wā sterilization
• Hāʻawi i ka hilinaʻi kiʻekiʻe i nā polokalamu lapaʻau liʻiliʻi

Nā Mea i Hoʻohana Maʻamau ʻia no nā PCB Ultrasound Lapaʻau

1. Nā Laminate Alapine Kiʻekiʻe

• Nā Mea Hana: Rogers RO4350B, Taconic RF-35
• Nā Hiʻohiʻona: Haʻahaʻa dielectric pohō (Df), paʻa dielectric mau (Dk)
• Noi: Papa hōʻailona ma nā papa hoʻokele transducer

2. FR-4 me ka Tg Hoʻonui ʻia

• Nā Mea Hana: FR-4 Tg170+, S1000-2M
• Nā Hiʻohiʻona: Hana maikaʻi ka wela, kūpono ke kumukūʻai
• Noi: Nā modula mana, nā papa hoʻokele

3. Polyimide no nā Flex Circuits

• Nā Hiʻohiʻona: Kūleʻa kiʻekiʻe, kūpaʻa wela maikaʻi loa
• Noi: Nā pilina Probe, nā mea hana ultrasound hiki ke hoʻohana ʻia

4. Nā Papahana Keramika

• Nā Mea Hana: Al₂O₃ (alumina), AlN (alumini nitride)
• Nā Hiʻohiʻona: ʻO ka conductivity thermal kūikawā, hoʻohana ʻia no nā hoʻolālā mana kiʻekiʻe miniaturized
• Noi: Nā ʻaoʻao mua o ka ultrasound diagnostic kiʻekiʻe

Nā Manaʻo Hoʻolālā Koʻikoʻi

• Mana Hoʻomau Dielectric: He mea nui no ka mālama ʻana i ka wikiwiki o ka hōʻailona a me ka hoʻohālikelike ʻana o ka impedance
• Ka Pohō o ka Tangent (Df): Hoʻomaopopo ka Df haʻahaʻa i ka maopopo o ka hōʻailona a me ka hoʻohaʻahaʻa haʻahaʻa
• Ka Hoʻopili ʻana o ka Makū: ʻO nā mea me ka emi ʻana o ka makū e kūʻē i ka hōʻino ʻana i ka wā sterilization
• Hoʻokō RoHS a me Biocompatibility: Pono e hoʻokō i nā lula olakino e like me RoHS, REACH, a me nā kūlana pili i ka FDA

ʻO ke koho ʻana i nā mea PCB kūpono no nā mea hana ultrasound pae lapaʻau ʻoi aku ia ma mua o kahi hoʻoholo ʻenekinia—he mea ia e pili ana i ka palekana o ka mea maʻi a me ka pololei o ke kauka. ʻO ka hui pū ʻana me kahi mea hana PCB akamai i ʻike i nā kūlana lapaʻau e hōʻoiaʻiʻo ana e hoʻokō kāu huahana i nā koi hoʻoponopono a me ka hana.
