Xulashada Agabka ee PCB-yada Ultrasound-ka ee Heerka Caafimaadka
Nidaamyada sawir-qaadista Ultrasound-ka waxay u baahan yihiin saxnaan sare, gudbinta calaamadaha soo noqnoqda sare, isku hallayn, iyo iswaafajin bayooloji. Xuddunta nidaamyadan waxaa ku yaal PCB-ga, xulashada agabka saxda ahna waa muhiim si loo hubiyo badbaadada, saxnaanta, iyo waxqabadka muddada dheer ee codsiyada caafimaadka.
Maxay Muhiim u tahay Xulashada Agabka ee PCB-yada Caafimaadka ee Ultrasound-ka?
Codsiyada heerka caafimaadka, gaar ahaan sawir-qaadista ogaanshaha, PCB-yadu waa inay:
- Taageer gudbinta calaamadaha soo noqnoqda sare (badanaa 20-100 MHz)
- Hubi xasilloonida kulaylka iyo luminta calaamadda oo hooseysa
- Ku habboonow walxaha biocompatible ama aan sun ahayn
- Joogtee xasilloonida cabbirka inta lagu jiro jeermis-dilista
- Bixi kalsooni sare oo ku saabsan aaladaha caafimaad ee is haysta
Qalabka Caadiga ah ee Loo Isticmaalo PCB-yada Ultrasound-ka Caafimaadka
1. Laminates-yada Soo Noqnoqda Sare
- Qalabka: Rogers RO4350B, Taconic RF-35
- Astaamaha: Lumis dielectric hooseeya (Df), joogto dielectric deggan (Dk)
- Codsiga: Lakabka calaamadda ee looxyada darawalka transducer
2. FR-4 oo leh Tg la xoojiyay
- Qalabka: FR-4 Tg170+, S1000-2M
- Astaamaha: Waxqabadka kulaylka wanaagsan, kharash-ool ah
- Codsiga: Modules Power, looxyada xakamaynta
3. Polyimide ee Wareegyada Laablaaban
- Astaamaha: Dabacsanaan sare, iska caabin kulayl oo aad u fiican
- Codsiga: Isku-xirka baaritaanka, aaladaha ultrasound-ka ee la xiran karo
4. Substrates-ka dhoobada ah
- Qalabka: Al₂O₃ (alumina), AlN (alumina nitride)
- Astaamaha: Gudbinta kulaylka oo heer sare ah, oo loo isticmaalo naqshado yar yar oo awood sare leh
- Codsiga: Ultrasound-ka ogaanshaha ee heerka sare ah ee hore-u-dhaca
Tixgelinta Naqshadeynta Muhiimka ah
- Xakamaynta Joogtada ah ee Dielectric: Muhiim u ah ilaalinta xawaaraha calaamadaha iyo isku-xidhka iska caabbinta
- Lumis Tangent (Df): Df-ka hoose wuxuu hubiyaa cadayn calaamadeed oo wanaagsan iyo qallooc hoose
- Nuugista Qoyaanka: Alaabada nuugista qoyaanka yar ay iska caabiso burburka inta lagu jiro jeermis-dilista
- U hoggaansanaanta RoHS iyo Bayoolojiga: Waa inuu buuxiyaa xeerarka caafimaadka sida RoHS, REACH, iyo heerarka la xiriira FDA
Doorashada qalabka PCB ee saxda ah ee loogu talagalay aaladaha ultrasound-ka ee heerka caafimaadka waa wax ka badan go'aan injineernimo - waa arrin ku saabsan badbaadada bukaanka iyo saxnaanta caafimaad. La shaqaynta soo saaraha PCB-ga khibradda leh ee yaqaan heerarka caafimaadka waxay hubineysaa in badeecadaadu ay buuxiso shuruudaha sharciyeynta iyo waxqabadka labadaba.
