Chifukwa Chakuwotcherera Njira Yowotcherera Nyali ya LED Nyali Yakufa

Panthawi yopanga, mikanda ina ya nyali imakumana ndi zochitika kuti pali chodabwitsa kuti pali chodabwitsa cha chimodzi, chingwe, ndi mikanda yambiri ya nyali poyesa. The kuwotcherera njira akhoza kugawidwa mu kuwotcherera chitsulo magetsi, Kutentha nsanja kuwotcherera ndi kuwotcherera reflux, etc.: A, ambiri magetsi chitsulo kuwotcherera, monga zitsanzo ndi kukonza. Chifukwa opanga ambiri omwe alipo ndi opulumutsa ndalama, ambiri mwa asilikali ogulidwa achitsulo chamagetsi amakhala ambiri. Zogulitsa zosayenerera nthawi zambiri zimakhala zosakhazikika, ndipo pali kutayikira. Izi zikufanana ndi kupanga lupu lopangidwa ndi kutayikira kwachitsulo chowotcherera nsonga-kuwotcherera kwa thupi laumunthu-dziko lapansi, zomwe zikutanthauza nthawi zambiri- Mazana a nthawi mphamvu yamagetsi yomwe nyali idawonjezedwa idawonjezedwa ku mkanda wa nyali ya LED, ndipo nthawi yomweyo anaziwotcha izo. Zindikirani: Mkhalidwe wa gulu lamagetsi lokhazikika udzakhala wovuta kwambiri, chifukwa thupi la munthu likalumikizidwa ndi lamba wa electrostatic, kukana pansi kumakhala kochepa, ndipo mphamvu yochokera mthupi la munthu kupita ku mikanda ya nyali idzakhala yayikulu. Palinso ambiri nyali mikanda kuonongeka mavuto. B, nyali yakufa yopangidwa ndi nsanja yotenthetsera yowotcherera. Chifukwa cha mndandanda wa zitsanzo za nyali zopitirira, makampani ambiri kuti akwaniritse zosowa zamagulu ang'onoang'ono ndi mndandanda wa zitsanzo, chifukwa cha mtengo wotsika wa zipangizo, kapangidwe kosavuta ndi ntchito, nsanja yotentha yakhala chida chabwino kwambiri chopangira. ntchito chilengedwe (Mwachitsanzo: pali vuto kuti kutentha malo ndi zimakupiza) ndi mlingo mchitidwe ndi kulamulira kuwotcherera oyendetsa ndi kulamulira kuwotcherera liwiro wakhala vuto lalikulu la nyali akufa. Komanso Kutentha Platform zida grounding zinthu. C, kuwotcherera reflux, nthawi zambiri njira yowotcherera ndiyo njira yodalirika yopanga, yoyenera kupanga ndi kukonza zambiri. Ngati opaleshoniyo ili yosayenera, imayambitsa magetsi akufa kwambiri, monga kusintha kosasinthika kwa kutentha, kusayenda bwino kwa makina, ndi zina zotero. 2. Kusungirako kolakwika kumayambitsa nyali zakufa: Vuto lamtunduwu ndilofala kwambiri. Popeza vuto la chinyezi kuteteza chinyezi - umboni pambuyo phukusi kutsegulidwa, chisindikizo cha mikanda nyali makamaka ntchito silikoni zipangizo. Malinga ndi zina mayamwidwe madzi makhalidwe, nyali mkanda phala pambuyo chinyezi anaika ndi chinyezi mkanda phala. Pambuyo pa bolodi, silikoni ya silikoni itatha kuwotcherera kwapamwamba - kutentha kumakhala kotentha komanso kogwirizana. Ulusi wagolide, chip, ndi mabulaketi zidzapunthwa ndipo ulusi wagolide udzaduka. Malo ounikira adzapangidwa. M'chilengedwe, kutentha kosungirako ndi -40 C- 100 C, ndi chinyezi chapafupi ndi 85%; ndikwabwino kugwiritsa ntchito LED mkati mwa miyezi itatu pansi pamikhalidwe yake yoyambira kuti mupewe dzimbiri la bulaketi; pamene thumba la ma CD la LED likutsegulidwa, thumba la phukusi limatsegulidwa. Pambuyo pake, gwiritsani ntchito mwamsanga. Panthawiyi, kutentha kosungirako ndi 5 -30 , ndi chinyezi chapafupi ndi pansi pa 60%. 3. Kuyeretsa kwa Chemical: Osagwiritsa ntchito madzi osadziwika amadzimadzi kuyeretsa LED, chifukwa izi zitha kuwononga pamwamba pa colloid ya LED komanso kuyambitsa ming'alu ya collagen. Ngati ndi kotheka, chonde ntchito mowa - thonje swabs mu firiji ndi mpweya wabwino chilengedwe. Nthawi imayendetsedwa bwino mu Mphepo imodzi yamphepo yatha. 4, kupindika kumayambitsa nyali zakufa: Chifukwa cha kusinthika kwa mbale zina, wogwiritsa ntchitoyo amakhala pulasitiki. Chifukwa cha kusinthika kwa bolodi, mikanda ya nyali yomwe ili pamenepo idzawonongekanso nthawi yomweyo. Pali mtundu uwu wa bolodi kwa opaleshoni ya pulasitiki isanayambe kupanga. Kusonkhana kwa nthawi yayitali ndi kuyenda kungayambitsenso zochitikazo. Palinso stacking. Pofuna kupangitsa kuti ntchitoyo ikhale yosavuta, bolodi la nyali limayikidwa pakufuna kwake. Chifukwa cha mphamvu yokoka, mikanda ya nyale yapansi idzasinthidwa kukhala ulusi wagolide. 5. Mapangidwe a kutentha kwa kutentha, magetsi ndi bolodi lounikira sizikugwirizana: Chifukwa cha mphamvu zopanda malire kapena kusankhidwa kwa magetsi, magetsi amaposa malire (ultra -current, instant impact); Kuwala koyambirira kutsika 6, fakitale yoyambira: iyenera kuyang'ana ngati mzere wonse wa fakitale uli wabwino. 7, magetsi osasunthika: magetsi osasunthika angayambitse ntchito ya LED. Ndikofunikira kuteteza ESD kuti isawononge ma LED. A, Kuzindikira kwa LED ndi kuphatikiza kuyenera kubweretsa zibangili zotsutsa-static ndi magolovesi odana ndi static. B. Zida zowotcherera ndi zida zoyesera, matebulo ogwirira ntchito, zoyikapo zosungirako, etc. iyenera kusungidwa bwino. C. Gwiritsani ntchito ion fan kuti muchotse magetsi osasunthika omwe amapangidwa ndi mikangano panthawi yosungira ndi kusonkhanitsa panthawi yosungira ndi kusonkhanitsa. D. Bokosi lopangira ndi LED limagwiritsa ntchito zosakaniza zotsutsana ndi static, ndipo chikwama choyikamo chimagwiritsa ntchito thumba lamagetsi lokhazikika. E. Musakhale ndi vuto, gwirani LED. Chodabwitsa chomwe chidzachitike ndi ma LED owonongeka ndi ESD ndi: A. Kutuluka kosiyana, kuwala kumapangitsa kuwalako. B. Mtengo wamagetsi umakhala wocheperako. LED sangathe kuwala pamene otsika -pano madalaivala. 8. Kuwotcherera kosakwanira kumapangitsa kuti magetsi asawalitse.
