Nigute wahitamo ibikoresho bya PCB bikwiye kuri sisitemu za Radar zigezweho?

Guhitamo ibikoresho bya PCB ni ikintu cy'ingenzi mu miterere ya sisitemu ya radar, bigira ingaruka ku mikorere, ubwizerwe, n'igiciro. Imikoreshereze itandukanye ya radar, nka radar y'imodoka ya millimetero-wave, radar y'ingabo zirwanira mu kirere, na radar igenzura ubutaka, bisaba ibikoresho byihariye bya PCB. Iyi nkuru itanga ubuyobozi burambuye bwo guhitamo ibikoresho bya PCB bikwiye kuri sisitemu za radar kugira ngo wongere imikorere n'imikorere myiza.

Kuki Ibikoresho bya PCB ni ingenzi muri sisitemu za Radar

Ibisabwa inshuro nyinshi

Sisitemu za radar zikora mu ntera zo hejuru, nka 24 GHz cyangwa 77 GHz kuri radar y'imodoka.

Ibimenyetso bifite umurongo munini bisaba ibikoresho bifite umurongo muto uhoraho (Dk) n'umutakaro muto wa dielectric (Df) kugira ngo ikimenyetso kibe cyiza kandi kigabanye igihombo.

Imikorere y'imicungire y'ubushyuhe

Sisitemu za radar zikunze gukora ku ngufu nyinshi. Ibikoresho bifite ubushyuhe bwinshi ni ingenzi cyane kugira ngo ubushyuhe bushobore gukwirakwira neza.

Kwizerwa mu bihe bikomeye

Sisitemu za radar z'imodoka zigomba kwihanganira ubushyuhe bwinshi, ubushuhe, n'imitingito.

Radar za gisirikare zihura n’imimerere mibi cyane y’ibidukikije, zikenera ibikoresho bihamye kandi biramba.

Ibikoresho bisanzwe bya PCB kuri sisitemu za Radar

Ibikoresho bya Rogers

Ubwoko bw'ibicuruzwa byasabwe: Rogers 5880, Rogers 4350B

Ibiranga by'ingenzi:

Ihindagurika ry'amashanyarazi rigabanuka n'igihombo

Ubushyuhe buhamye cyane kandi CTE nke (coefficient of thermal expansion)

Ikwiriye gukoreshwa muri radar ifite milimetero n'amajwi menshi.

Ingero nziza zo gukoresha: Radar ya milimetero, radar ya gisirikare, modules z'itumanaho zikoresha ikoranabuhanga rya "high-frequency".

Ibikoresho bya Taconic

Ubwoko bw'ibisabwa: Taconic TLY, RF-35

Ibiranga by'ingenzi:

Ihendutse ugereranije n'ibikoresho bya Rogers

Imikorere iringaniye ku bikorwa bikoreshwa hagati kugeza hejuru.

Ingero nziza zo gukoresha: Radar y'imodoka, Radar igenzura imikorere y'imodoka.

Ibikoresho bya FR-4 byahinduwe

Ibiranga by'ingenzi:

Ihendutse kandi ihendutse

Kongera imikorere binyuze mu gusiga irangi ryihariye ku bikorwa byo hagati.

Ingero nziza zo gukoresha: Sisitemu za radar zihendutse, ibikoresho bito byo kugenzura.

Ibikoresho bya Polyimide (PI)

Ibiranga by'ingenzi:

Ibikoresho byoroshye gukoresha mu gushushanya ibintu bigoye

Imiterere myiza cyane y'ubushyuhe n'imikorere ya mashini.

Uburyo bwiza bwo gukoresha: Module za radar zihujwe, sisitemu za antene zoroshye.

Intambwe zo Guhitamo Ibikoresho Byiza bya PCB

Hitamo ukurikije inshuro

Koresha ibikoresho bigabanya igihombo nka Rogers 5880 kugira ngo radar ifite umurongo wo hejuru.

Hitamo FR-4 yahinduwe kugira ngo ikoreshwe mu buryo bwihuta kandi bukoresha inshuro nke.

 Tekereza ku bikenewe mu amashanyarazi n'ubushyuhe

Radar zifite ingufu nyinshi zigomba gukoresha ibikoresho bifite ubushobozi bwo gutwara ubushyuhe bwinshi, nka laminate zikozwe mu byuma.

 Huza imiterere y'ibidukikije

Radar za gisirikare n'iz'ikirere zungukira ku bikoresho bipima ubushyuhe bwinshi kandi birwanya ubushuhe nka PTFE cyangwa polyimide.

Imikorere n'Ikiguzi by'Iterambere ry'Imari

Ku mishinga ifite ingengo y'imari nto, hitamo FR-4 yahinduwe mu gihe ugenzura ko yujuje ibisabwa by'ingenzi mu mikorere.

Amakosa akunze kugaragara mu guhitamo ibikoresho bya PCB

Kwishingikiriza ku gikoresho kimwe gusa

Moduli zitandukanye za radar zishobora gukenera ibikoresho bitandukanye bya PCB. Urugero, module za RF zikenera Rogers, mu gihe module zo kugenzura zishobora gukoresha FR-4.

 Kwita ku micungire y'ubushyuhe

Nubwo ibikoresho bikoresha ubushyuhe neza, imiterere ikwiye y'ibigega by'ubushyuhe irakenewe kugira ngo ubushyuhe bushire neza.

 Kwirengagiza uburyo ibintu bitoroshye gukora

Ibikoresho bifite imikorere myiza akenshi bisaba ubushobozi bwihariye bwo kubitunganya, bityo rero menya neza ko umucuruzi wawe ashobora guhangana n'izi ngorane.

Umwanzuro: Urufunguzo rw'imikorere idasanzwe ya PCB ya Radar

Guhitamo ibikoresho bya PCB bikwiye ni ngombwa kugira ngo sisitemu ya radar ikore neza, yiringire kandi ikoreshe neza amafaranga. Ku bikoresho bya radar bifite frequency nyinshi, Rogers na Taconic bitanga imikorere myiza cyane. Ku bikoresho bifite ingengo y'imari iciriritse, FR-4 yahinduwe ishobora gutanga ubundi buryo buhendutse.

Gukorana n'uruganda rwa PCB rufite uburambe bitanga uburyo bwo guhitamo neza ibikoresho no gushyigikira ibikorwa byawe bya radar.
