Ese Ultrasonic-Weldable Lacquered Aluminium Foil Nibyiza kubikoresho byo mu kirere Sensor Cable Shielding?

Uburyo bwa kijyambere bwo mu kirere bwogukoresha amashanyarazi (EWIS) - bukoreshwa mu ndege zubucuruzi, indege za gisirikare, indege ziguruka mu mujyi (UAM), hamwe n’imiyoboro ikora ibyogajuru - ikora mu buryo bukabije bw’amashanyarazi (EMI) hamwe n’ibibazo bikabije by’ibidukikije. Umugozi wihuta cyane wogukwirakwiza ibimenyetso bya micro-volt bigomba gukomeza kuba inyangamugayo mugihe wihanganira gusiganwa ku magare bikomeza, guhindagurika kwimiterere, hamwe nimbogamizi zikomeye.

Gakondo gakondo iremereye ikingira ikingira yongeraho uburemere bupfuye kandi ikora cyane kubikorwa byo kurangiza. Ultrasonic-weldable lacquered aluminium foil ( 8000 serie na 1000 serie yoroheje ya aluminiyumu yometse kuri ultra-thin, itwara cyangwa ikoresha ubushyuhe bwa lacquer sisitemu ) itanga ubundi buryo bwiza. Muguhuza $ 100 % $ bikomeza EMI hejuru yuburinganire hamwe na ultrasonic ultrasonic wire-to-foil guhuza, ibi bikoresho bigabanya ibikoresho bya EWIS, bikuraho clamp yubutaka, kandi bikanatanga ibimenyetso byizewe cyane mumiyoboro ya sensororo yindege.

Imyubakire ya Mass & High-Frequency Urusaku Iterabwoba

Ibikoresho byo mu kirere (urugero, imirongo ya thermocouple, ibyuma byinyeganyeza, igenzura rya moteri ya FADEC, hamwe n’itumanaho rya telemeteri) bihura n’ibidukikije bidasanzwe:

Urusaku rwinshi rwa EMI Urusaku: Impanuka ya Radar, inkuba (HIRF), hamwe na elegitoroniki ifite ingufu nyinshi zitera urusaku rwinzibacyuho mumirongo ya sensor idafunze, bigatuma sensor igenda cyangwa gusoma telemetrie yibinyoma.

Ibihano biremereye: Ingabo zisanzwe zikozwe mu muringa zongerera uburemere ibirometero byinshi kuri kabili ya EWIS. Byongeye kandi, meshes ikozweho igaragaramo icyuho cya diyama ya microscopique ituma imirasire yumuriro mwinshi wa electronique (> 1 GHz) yinjira.

Kugereranya: Umuringa Uremereye Umuringa Ukingira na Ultrasonic-Weldable Lacquered Foil

Kugereranya Ibikoresho byo Kugereranya

Matrix iri hepfo igereranya uburyo bwa gakondo bwo gukingira insinga zirwanya ultrasonic-weldable lacquered aluminium foil ya porogaramu zikoreshwa mu kirere:

Ibyingenzi Byumwuga Mubyiza bya Aerosmace Sensor Cable Shielding

Ibibazo

Q1: Kuki kaseti ya aluminium / PET isanzwe igoye kugwa mumigozi yindege?

Igisubizo: kaseti isanzwe ya aluminium / PET ikoresha ibyuma bidatwara ibintu cyangwa ibyuma bya polymer inyuma. Imiyoboro y'amazi yishingikiriza kumuvuduko wumubiri wonyine, ishobora okiside, igabanuka munsi yinyeganyeza yindege, kandi igatera imbaraga zo guhangana nubutaka mugihe runaka.

Q2: Nigute gusudira ultrasonic bifatanyiriza hamwe insinga zumuringa kumashanyarazi ya aluminiyumu?

Igisubizo: Ihembe rya ultrasonic gusudira rikoresha inshuro nyinshi zinyeganyega (20 - 40 kHz) mukibazo. Ibi bihita bimura urwego ruto rukora lacquer hanyuma rugasenya firime ya oxyde, bigakora umurongo ukomeye wa atome hagati yumuringa wumuringa na fayili ya aluminiyumu udashonga ibyuma.

Q3: Ese lacquer ikora irashya cyangwa isohora imyotsi yuburozi mugihe cyo gusudira ultrasonic?

Igisubizo: Oya Ultrasonic gusudira ni inzira ikonje, ikomeye-itanga ubushyuhe buke bwaho. Lacquer yimuwe mumashanyarazi kure yakarere kegereye aho gutwikwa nubushyuhe, yirinda imyotsi yuburozi, gutwika, cyangwa kwangirika kwubushyuhe bwangiza insinga zegeranye.

Q4: Fayili ya aluminiyumu irashobora gusimbuza burundu gukingira umuringa?

Igisubizo: Mumurongo mwinshi-imbaraga nke za sensor insinga, yego. Nyamara, kumirongo ifite ingufu nyinshi zisaba imbaraga zo gukanika gukanika cyangwa gukomera kwinshi (<1 MHz), abajenjeri bakunze gukoresha ingabo ya Hybrid: icyuma cyimbere cyimbere ya 100% ya EMI ikwirakwizwa cyane hamwe nigitereko cyoroshye cyo gukanika imbaraga.

Q5: Ni ubuhe bushyuhe bwa aluminiyumu bukenewe ku nsinga zo mu kirere zoroshye?

Igisubizo: Birakenewe byuzuye fayili (O temper) irakenewe. Ubushyuhe bwa $ O $ butanga uburebure burebure (> 6% - 10%), butuma umugozi wunama inshuro nyinshi hafi yindege zikomeye radiyo itaguye cyangwa ngo itanyagure icyuma gikingira.

Umwanzuro

Ultrasonic-weldable lacquered aluminium foil iruta imiringa gakondo y'umuringa hamwe na kaseti isanzwe yometse kuri kasitori yo mu kirere ikingira ibyuma, itanga amafaranga menshi yo kuzigama, kurinda EMI itagira ikizinga, no kurangiza vuba, kwizerwa.

Kugirango uhindure ibikoresho byatoranijwe kubikoresho byo mu kirere:

Kugaragaza Alloy & Temper (8011-O cyangwa 1235-O): Saba fayili yoroheje ya aluminiyumu yuzuye (12μm- 25μm) kugirango urebe neza ko irwanya kandi irira mugihe cyo gupfunyika byihuta.

Manda ya Outgassing Yubahiriza (ASTM E595): Kubikoresho bya EWIS bigana umwanya munini cyangwa murwego rwo hejuru, shyira mu bikorwa icyemezo gikomeye cya ASTM E595 (TML <1.0%, CVCM <0.01%) kugirango wirinde imiti ihindagurika imbere yinyanja.

Kwemeza ibipimo bya Ultrasonic Weld: Menya neza ko formulaire ya lacquer ikora ishyigikira ibihe byihuta byo gusudira ultrasonic (<amasegonda 0.5) hamwe no kurwanya amashanyarazi make (<2 m Ω ) hamwe nimbaraga zo gukurura hamwe (> 8 N).
