Kōwhiringa Rauemi mō ngā PCB Ultrasound Taumata-Hauora

Ko ngā pūnaha whakaahua oro-oro e hiahia ana ki te tuku tohu tino tika, te auau teitei, te pono, me te hototahi ki te koiora. Kei te ngākau o ēnei pūnaha te PCB, ā, he mea nui te whiriwhiri i ngā rauemi tika hei whakarite i te haumaru, te tika, me te mahi roa i roto i ngā tono hauora.

He aha te hiranga o te whiriwhiri rauemi i roto i ngā PCB Ultrasound Hauora?

I roto i ngā tono taumata hauora, inā koa ko te whakaahua tātaritanga, me:

• Tautoko i te tuku tohu auau-teitei (te nuinga o te wā 20–100 MHz)
• Kia mau te pumau o te wera me te iti o te ngaronga tohu
• Kia hototahi ki ngā rauemi koiora-hototahi, ki ngā rauemi kore-paitini rānei
• Kia mau tonu te pumau o ngā āhuatanga i te wā e whakahoromata ana
• Tuku i te pono teitei i roto i ngā taputapu hauora kiato

Ngā Rauemi e Whakamahia Ana mō ngā PCB Ultrasound Hauora

1. Ngā Papa Whakakī Auau-Teitei

• Rauemi: Rogers RO4350B, Taconic RF-35
• Ngā Āhuatanga: He iti te ngaronga hiko (Df), he pūmau hiko pumau (Dk)
• Taupānga: Paparanga tohu i roto i ngā papa taraiwa whakawhiti

2. FR-4 me te Tg Whakarei ake

• Rauemi: FR-4 Tg170+, S1000-2M
• Ngā Āhuatanga: He pai te mahi wera, he iti te utu
• Taupānga: Ngā kōwae hiko, ngā papa whakahaere

3. Polyimide mō ngā Ara Hāngai

• Ngā Āhuatanga: He ngāwari teitei, he ātete wera pai rawa atu
• Taupānga: Ngā hononga tirotiro, ngā taputapu ultrasound ka taea te mau

4. Ngā Papa Uku

• Ngā Rauemi: Al₂O₃ (alumina), AlN (konumohe nitride)
• Ngā Āhuatanga: He kawe wera tino pai, e whakamahia ana mō ngā hoahoa iti-mana-nui
• Taupānga: Ngā pito mua o te tātaritanga ultrasound kounga teitei

Ngā Whakaaro Matua mō te Hoahoa

• Mana Pūmau Ārai Hiko: He mea nui mō te pupuri i te tere tohu me te taurite i te aukati
• Te Ngaronga o te Pānga (Df): Ko te iti o te Df ka whakarite kia pai ake te mārama o te tohu me te iti o te whakapohehe
• Te mimiti makuku: Ko ngā rauemi he iti te mimiti i te makuku ka ātete ki te pirau i te wā e whakahoromata ana
• Te Whakatutukitanga o te RoHS me te Whakaōritenga Koiora: Me tutuki i ngā ture hauora pēnei i te RoHS, REACH, me ngā paerewa e pā ana ki te FDA

Ehara i te mea he whakatau hangarau noa iho te whiriwhiri i ngā rauemi PCB tika mō ngā taputapu ultrasound kounga hauora—he mea e pā ana ki te haumaru o te tūroro me te tika o te haumanu. Mā te mahi tahi me tētahi kaihanga PCB mātau e mōhio ana ki ngā paerewa hauora ka tutuki i tō hua ngā whakaritenga ture me te mahi.
