Iyo nheyo uye basa re ultrasonic probe

1. Chii chinonzi ultrasonic probe

Iyo probe inoshandiswa mukuyedzwa kweultrasonic ndeye transducer inoshandisa piezoelectric mhedzisiro yezvinhu kuona shanduko yesimba remagetsi uye inonzwika simba.Chinhu chakakosha muprobe iwafer, inova crystal imwe chete kana polycrystalline sheet ine piezoelectric effect.Basa nderekushandura simba remagetsi uye simba rinonzwika kune mumwe nemumwe.

2. Nheyo ye ultrasonic probe

Kuferefeta kwakashongedzerwa nemawafer maviri, imwe seyekufambisira uye imwe seanogamuchira, inonziwo kupatsanurwa probe kana yakasanganiswa mbiri mbiri.Iyo dual element probe inonyanya kuumbwa socket, shell, residual layer, transmitting chip, receive chip, delay block, etc. Inoshandisa vertical longitudinal wave sound beam kuongorora workpiece.Kuenzaniswa nemaprobes akatwasuka, dual crystal yakatwasuka probes ine zvirinani zvekuona kugona kwepedyo-pamusoro pehurema;kune rough kana curved yekuona nzvimbo, vane zvirinani coupling maitiro.

Inoshandiswa mune semi-otomatiki kana otomatiki yekuona kukanganisa masisitimu.Kana iyo axis yemutsindo inoburitswa neprobe iri perpendicular kune yekuona nzvimbo, iyo longitudinal wave direct sound beam inotarisa workpiece;gadzirisa ruzha danda axis yeprobe kuti iite imwe kona ine nzvimbo yekuona.Iyo ruzha danda inodzoserwa pane interface pakati pemvura uye workpiece.Iyo yakarereka yakachinjika wave inonzwika danda inogadzirwa muworkpiece kuti itarise workpiece.Iyo plexiglass kana yakarapwa epoxy resin pamberi peiyo probe chip inogadziriswa mune imwe arc (spherical kana cylindrical), uye inotangisa-yakatarisana kana mutsara-yakatarisana nemvura inonyudza probe inogona kuwanikwa.

3. Basa re ultrasonic probe

1) Shandura masaisai eruzha akadzoka kuita magetsi emagetsi;

2) Iko kudzora nzira yekuparadzira yeiyo ultrasonic wave uye dhigirii rekuisa simba.Kana iyo kona yechiitiko che probe ichishandurwa kana iyo diffusion angle ye ultrasonic wave yashandurwa, iro simba guru reizwi wave rinogona kubaiwa mukati mepakati pamakona akasiyana kana kutungamira kweiyo ruzha wave inogona kuchinjwa kuti igadzirise kugadzirisa. .Rate;

3) Kuwana waveform kutendeuka;

4) Iko kudzora kuwanda kwekushanda, iyo inokodzera mamiriro akasiyana ekushanda.
