Guhitamo ibikoresho bya mudasobwa zipima ultrasound zo mu rwego rw'ubuvuzi

Sisitemu zo gufata amashusho ya Ultrasound zisaba kohereza ibimenyetso neza cyane, byizewe, kandi bihura neza n’ibindi. Ishingiro ry’izi sisitemu ni PCB, kandi guhitamo ibikoresho bikwiye ni ingenzi cyane kugira ngo habeho umutekano, ubunyangamugayo, n’imikorere myiza mu buvuzi.

Kuki guhitamo ibikoresho ari ingenzi muri mudasobwa zipima ikoranabuhanga rya Ultrasound mu buvuzi?

Mu buryo bw’ubuvuzi, cyane cyane amashusho yo gusuzuma indwara, PCB zigomba:

• Ishyigikira uburyo bwo kohereza amajwi mu buryo bwo hejuru (ubusanzwe hagati ya 20–100 MHz)
• Menya neza ko ubushyuhe buhamye kandi ko ikimenyetso cyatakaye cyane
• Bihuze n'ibikoresho bihuye n'ibinyabuzima cyangwa ibidafite uburozi
• Gumana ubuziranenge bw'ibipimo mu gihe cyo gufunga
• Bitanga uburyo bwo kwizerwa cyane mu bikoresho bito by'ubuvuzi

Ibikoresho bikunze gukoreshwa mu gupima ibyuma bipima ikirere hakoreshejwe ikoranabuhanga rya Ultrasound

1. Laminate zikoresha inshuro nyinshi

• Ibikoresho: Rogers RO4350B, Taconic RF-35
• Ibiranga: Igihombo gito cya dielectric (Df), dielectric constant ihamye (Dk)
• Ikoreshwa: Urupapuro rw'ikimenyetso mu mbaho ​​z'abashoferi ba transducer

2. FR-4 ifite Tg yongerewe

• Ibikoresho: FR-4 Tg170+, S1000-2M
• Ibiranga: Imikorere myiza y'ubushyuhe, ihendutse
• Ikoreshwa: Modules z'amashanyarazi, ibyuma byo kugenzura

3. Polyimide yo gukoresha imiyoboro ihindagurika

• Ibiranga: Koroherwa cyane, kurwanya ubushyuhe neza
• Uburyo bwo kuyikoresha: Ibikoresho byo gupima, ibikoresho bya ultrasound byambarwa

4. Ibikoresho bya Ceramic

• Ibikoresho: Al₂O₃ (alumina), AlN (aluminamu nitride)
• Ibiranga: Uburyo budasanzwe bwo gutwara ubushyuhe, bukoreshwa mu bishushanyo mbonera bito bifite ingufu nyinshi
• Uburyo bwo kuyikoresha: Uburyo bwo gusuzuma bwa ultrasound bwo mu rwego rwo hejuru

Ibintu by'ingenzi bigomba kwitabwaho mu gishushanyo mbonera

• Igenzura rihoraho rya Dielectric: Ni ngombwa mu kubungabunga umuvuduko w'ikimenyetso no guhuza impedance
• Igihombo (Df): Df yo hasi ituma ibimenyetso birushaho kuba byiza kandi bigahindura isura.
• Uburyo bwo kwinjiza ubushuhe: Ibikoresho bifite ubushuhe buke birwanya kwangirika mu gihe cyo gukaraba
• Iyubahirizwa rya RoHS n'iyubahirizwa ry'amategeko agenga ibidukikije: Agomba kubahiriza amabwiriza y'ubuvuzi nka RoHS, REACH, na FDA ajyanye n'amabwiriza

Guhitamo ibikoresho bya PCB bikwiye ku bikoresho bya ultrasound byo mu rwego rw'ubuvuzi birenze gufata icyemezo cy'ubuhanga gusa—ni ikibazo cy'umutekano w'umurwayi no kuba abikora neza. Gukorana n'uruganda rwa PCB rufite uburambe buzwi ku mahame y'ubuvuzi bituma ibicuruzwa byawe byuzuza ibisabwa n'amategeko ndetse n'imikorere yabyo.
