Flexible wedunhu magadzirirwo anoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kweakawanda mabhenefiti akadai sekuchinjika, kureruka, compactness uye yakakwirira kuvimbika.Nekudaro, senge kumwe kufambira mberi kwetekinoroji, inouya nemugove wayo wakanaka wezvinetso uye zvinokanganisa.Dambudziko guru mukugadzirwa kwedunhu rinochinjika ndeye electromagnetic radiation uye electromagnetic interference (EMI) kudzvanya, kunyanya mune yakakwirira-frequency uye yakakwirira-kumhanya maapplication.Mune ino blog post, isu tichaongorora dzimwe nzira dzinoshanda dzekugadzirisa idzi nyaya uye tive nechokwadi chekuita kwakakwana kwemasekete anochinja.
Tisati taongorora mhinduro, ngatitangei kunzwisisa dambudziko riripo.Electromagnetic radiation inoitika kana magetsi uye magineti minda yakabatana nekuyerera kwemagetsi ikozvino oscillate uye kuparadzira nemuchadenga.EMI, kune rumwe rutivi, inoreva kukanganiswa kusingafadzi kunokonzerwa neaya magetsi emagetsi.Mu-high-frequency uye high-speed applications, mwaranzi yakadaro uye kukanganisa kunogona kukanganisa zvakanyanya kushanda kweiyo flex circuit, zvichikonzera nyaya dzekushanda, kuderedzwa kwechiratidzo, uye kunyange kutadza kwehurongwa.
Zvino, ngationgororei dzimwe mhinduro dzinoshanda dzekugadzirisa nyaya idzi mukugadzira dunhu rinoshanduka:
1. Shielding tekinoroji:
Nzira inoshanda yekudzvanya mwenje wemagetsi uye EMI kushandisa tekinoroji yekudzivirira mukugadzira nekugadzira maseketi anochinjika.Kudzivirira kunosanganisira kushandisa zvinhu zvinoitisa, semhangura kana aluminium, kugadzira chinovharira chemuviri chinodzivirira minda yemagetsi kutiza kana kupinda dunhu.Yakanyatsogadzirwa kudzivirira inobatsira kudzora kuburitswa mukati meseketi uye kudzivirira isingadiwe EMI.
2. Grounding uye decoupling:
Kudzika kwakakodzera uye nzira dzekubvisa dzakakosha kudzikisa mhedzisiro yemagetsi emagetsi.Ivhu kana ndege yemagetsi inogona kuita senhovo uye inopa yakaderera-impedance nzira yekuyerera kwazvino, nekudaro ichidzikisa mukana weEMI.Uye zvakare, decoupling capacitors inogona kuiswa zvine hungwaru padyo nepamusoro-kumhanya zvikamu kudzvanyirira ruzha rwepamusoro uye kuderedza kukanganisa kwayo padunhu.
3. Kurongeka uye kuiswa kwechikamu:
Kurongeka uye kuiswa kwechikamu kunofanirwa kunyatsotariswa panguva yekugadzira flex circuit.Zvikamu zvinomhanya zvakanyanya zvinofanirwa kuparadzaniswa kubva kune mumwe nemumwe uye zviratidzo zvechiratidzo zvinofanirwa kuchengetwa kure nezvinobvira zveruzha.Kudzikisa kureba uye loop nzvimbo yechiratidzo chetrace inogona kuderedza zvakanyanya mukana weiyo electromagnetic radiation uye EMI matambudziko.
4. Chinangwa chesefa chinhu:
Kubatanidza zvinhu zvekusefa senge zvakajairwa modhi kuchovha, EMI mafirita, uye ferrite bead kunobatsira kudzvanya mwenje wemagetsi uye kusefa kunze ruzha rusingadiwe.Izvi zvikamu zvinovhara zvikwangwani zvisingadiwe uye zvinopa impedance kune yakakwira-frequency ruzha, ichidzivirira kubva pakukanganisa dunhu.
5. Kongiri uye tambo dzakadzika zvakanaka:
Zvibatanidza uye tambo dzinoshandiswa mukuchinjika wedunhu kugadzira ndiwo angangoita masosi emagetsi emagetsi uye EMI.Kuve nechokwadi chekuti zvikamu izvi zvakadzika pasi uye kuchengetedzwa zvinogona kuderedza matambudziko akadaro.Kunyatsogadzirwa tambo nhoo uye yepamusoro-mhando yekubatanidza ine ivhu rakaringana inogona kunyatso kudzikisa magetsi emagetsi uye EMI matambudziko.
Muchidimbu
Kugadzirisa iyo electromagnetic radiation uye EMI kudzvinyirira matambudziko muinochinjika yedunhu kugadzira, kunyanya mune yakakwirira-frequency uye yakakwirira-kumhanya maapplication, inoda yakarongeka uye yakazara maitiro.Kubatanidzwa kwemaitiro ekudzivirira, kudzika kwakaringana uye kupatsanura, kunyatsorongedza uye kuiswa kwechikamu, kushandiswa kwezvikamu zvekusefa, uye kuve nechokwadi chekudzika kwakaringana kwezvibatanidza uye tambo matanho akakosha ekudzikisa matambudziko aya.Nekushandisa zvigadziriso izvi, mainjiniya nevagadziri vanogona kuve nechokwadi chekushanda kwakakwana, kuvimbika uye kushanda kwemaseketi anochinjika mukukumbira maapplication.
