Abwenzi ambiri atsopano owonetsera LED ali ndi chidwi, chifukwa chiyani paulendo wopita ku zokambirana zambiri za LED, amayenera kubweretsa zophimba nsapato, mphete ya electrostatic, kuvala zovala zamagetsi ndi zipangizo zina zodzitetezera. Kuti timvetsetse vutoli, tiyenera kutchula chidziwitso chokhudzana ndi chitetezo chamagetsi osasunthika pakupanga ndi kuyendetsa chiwonetsero cha LED. M'malo mwake, zowonetsera zambiri za LED zimawoneka zakufa kapena zosawala, makamaka chifukwa cha magetsi osasunthika.
Magwero a magetsi osasunthika popanga zowonetsera za LED:
1. Zinthu, zipangizo.
2. Pansi, matebulo ogwira ntchito ndi mipando.
3. Zovala zogwirira ntchito ndi zotengera.
4. Pamalo opaka utoto kapena phula, organic ndi fiberglass zida.
5. Pansi konkire, kupaka utoto kapena phula, matailosi apulasitiki kapena zikopa zapansi.
6. Zovala zogwirira ntchito za Chemical, nsapato zogwira ntchito zopanda ma conductive, zovala zoyera za thonje.
7, Pulasitiki, mabokosi onyamula, mabokosi, matumba, ma trays, thovu liner.
Ngati anti-static imanyalanyazidwa nthawi iliyonse yopanga, zipangitsa kuti zida zamagetsi zisagwire ntchito kapena kuziwononga. Zida za semiconductor zikayikidwa payekhapayekha kapena kulowetsedwa mudera, ngakhale zilibe mphamvu, kuwonongeka kosatha kwa zida izi kumatha kuchitika chifukwa cha magetsi osasunthika. Monga mukudziwira bwino, LED ndi semiconductor mankhwala, ngati voteji pakati pa zikhomo ziwiri kapena kuposa za LED kuposa kusweka mphamvu chigawo dielectric, izo kuwononga chigawo chimodzi. Kuchepa kwa oxide wosanjikiza, kumapangitsanso kukhudzika kwa LED ndi driver IC kumagetsi osasunthika. Mwachitsanzo, kusowa kwa kudzaza kwa solder, mavuto ndi khalidwe la solder palokha, etc., akhoza kupanga njira zowonongeka zomwe zingayambitse kuwonongeka kwakukulu.
Kulephera kwamtundu wina kumachitika pamene kutentha kwa node kumadutsa malo osungunuka a semiconductor silicon (1415 ° C). Mphamvu yamagetsi yamagetsi osasunthika imatha kutulutsa kutentha komweko, kotero kuti vuto limachitika lomwe limalowa mwachindunji mu nyali ndi IC. Kulephera uku kumatha kuchitika ngakhale mphamvu yamagetsi ili pansi pamagetsi owonongeka a dielectric. Chitsanzo chodziwika bwino ndi chakuti LED ndi gawo la PN lopangidwa ndi diode, emitter ndi maziko a kuwonongeka pakati pa phindu lamakono zidzachepetsedwa kwambiri. LED palokha kapena dera dalaivala zosiyanasiyana mu IC ndi mphamvu ya magetsi malo amodzi, mwina si nthawi yomweyo kuwoneka kuwonongeka zinchito, izi zingakhale zowononga zigawo zambiri mu ntchito ndondomeko adzakhala kusonyeza, kotero zotsatira za moyo wa mankhwala LED ndi zakupha.
Kupanga chiwonetsero cha LED ndi njira yovuta kwambiri, yowoneka bwino, ulalo uliwonse sungakhoze kusiyidwa. Kuwonetsa chitetezo chamagetsi ndi gawo lofunikira la kupanga chiwonetsero cha LED, makampani akadali osazama mokwanira kuti amvetsetse chitetezo chamagetsi, mocheperako kuti akwaniritse zofunikira zaukadaulo wopanga ma LED, komanso amafunikira akatswiri ambiri kuti apitirize kuphunzira. ndi kukambirana pamodzi.
Momwe mungapewere magetsi osasunthika popanga chiwonetsero cha LED:
1. Kugwiritsa ntchito ma electrostatic sensitive circuit ogwira ntchito kuti achite chidziwitso cha electrostatic ndi maphunziro okhudzana ndi ukadaulo.
2. Kukhazikitsidwa kwa malo ogwiritsira ntchito anti-static, kugwiritsa ntchito static discharge floor, anti-static workbench, anti-static grounding lead ndi zida zogwiritsira ntchito, ndipo zidzapita kumalo osungira chinyezi kuposa 40.
3. Zowopsa zomwe zimachitika ndi magetsi osasunthika ku zida zamagetsi zimatha kumasulidwa kulikonse kuchokera kwa wopanga kupita ku zida zomwe zili m'munda. Zowopsa zimayambitsidwa ndi kusakwanira, kuphunzitsidwa bwino komanso kulephera kugwiritsa ntchito zida.Ma LED ndi zida zosasunthika.Zipatso za INGAN nthawi zambiri zimawonedwa ngati "zoyamba" potengera kusokonezeka. Tchipisi za INGAN nthawi zambiri zimatengedwa ngati "zoyamba" potengera kutengeka, pomwe ALINGAPLEDSSHI ndi "wachiwiri" kapena bwino.
4. Zipangizo zowonongeka za ESD zimatha kuwonetsa mdima, zosokoneza, zozimitsa, zazifupi kapena zochepa VF kapena VR. Zipangizo zowonongeka za ESD siziyenera kusokonezedwa ndi zochulukira pamagetsi, monga: chifukwa cha zolakwika zomwe zikuchitika panopa kapena kuyendetsa galimoto, chophatikizira chawafer, kuyika chishango chawaya kapena kutsekeka, kapena kupsinjika komwe kumachitika chifukwa cha chilengedwe.
5. Njira zotetezera ndi kuwongolera za ESD: makampani ambiri amagetsi ndi electro-optical ndi ofanana kwambiri ndi ESD, ndipo akwaniritsa bwino zida za ESD control, manipulation and master program. Mapulogalamuwa akhala akugwiritsidwa ntchito kuyambira kalekale kuti azindikire zamtundu wa zida za ESD. Chitsimikizo cha ISO-9000 chimamuphatikizanso munjira zowongolera.
