Kugwirizana kwa Inductor
M'zaka zaposachedwa, kufunikira kochepetsa kukula kwa zinthu zomwe zasonkhanitsidwa kwadzetsanso kuchepa kwakukulu kwa magawo azinthu zopangira ma inductor, zomwe zabweretsanso kufunikira kwaukadaulo wapamwamba wokweza tizigawo ting'onoting'onozi pama board awo.
Akatswiri apanga ma solder paste, zomatira, ndi njira zomangira zomwe zimalola kumangirira ma inductor terminals ku PCB popanda kugwiritsa ntchito mabowo. Madera athyathyathya (otchedwa pads) pa ma inductor terminals amagulitsidwa molunjika kumalo ozungulira amkuwa motero mawu akuti surface mount inductor (kapena transformer). Izi zimathetsa kufunika kubowola mabowo a zikhomo, potero kuchepetsa mtengo kupanga PCB.
Kulumikiza zomatira (gluing) ndiyo njira yodziwika kwambiri yolumikizira zolumikizira ku koyilo yolowera. Wogwiritsa ntchitoyo ayenera kumvetsetsa bwino zolinga zomangirira: kaya ndikungosunga chowongolera pa koyilo kapenanso kuziziritsa kwambiri potengera kutentha kwa koyilo yozikika ndi madzi.
Kulumikizana kwamakina ndiyo njira yolondola kwambiri komanso yodalirika yolumikizira owongolera ku ma coil olowetsa. Ikhoza kupirira kusuntha kwa kutentha ndi kugwedezeka kwa zigawo za koyilo panthawi ya utumiki.
Pali zochitika zambiri pomwe owongolera amatha kulumikizidwa osati kutembenuka kwa koyilo, koma kuzinthu zamapangidwe oyika ma induction monga makoma achipinda, mafelemu a zishango zamaginito, ndi zina zambiri.
Momwe mungayikitsire inductor ya radial?
The toroids akhoza Ufumuyo pa phiri ndi kaya zomatira kapena makina njira. Makapu owoneka ngati ma toroid amatha kudzazidwa ndi potting kapena encapsulation pawiri kuti amamatire ndikuteteza chilonda cha toroid. Kuyika kopingasa kumapereka mawonekedwe otsika komanso malo otsika amphamvu yokoka pamapulogalamu omwe amakumana ndi kugwedezeka komanso kugwedezeka. Pamene kukula kwa toroid kukukulirakulira, kuyika kopingasa kumayamba kugwiritsa ntchito malo ofunikira. Ngati pali malo m'malo otsekeredwa, kuyimitsa koyima kumagwiritsidwa ntchito kusunga malo a bolodi.
Zotsogola zochokera kumayendedwe a toroidal zimamangiriridwa ku ma terminals a phiri, nthawi zambiri ndi soldering. Ngati mawaya ozungulirawo ndi akulu komanso olimba mokwanira, wayawo ukhoza kukhala “wotsogolera wokha” ndikukhazikika pamutu kapena kukwera mu bolodi yosindikizidwa. Ubwino wodzipangira nokha ndi chakuti kuwononga ndalama ndi kusatetezeka kwa kulumikizana kwapakatikati kwa solder kumapewa. The toroids akhoza Ufumuyo pa phiri ndi kaya zomatira, makina njira kapena encapsulation. Makapu owoneka ngati ma toroid amatha kudzazidwa ndi potting kapena encapsulation pawiri kuti amamatire ndikuteteza chilonda cha toroid. Kuyika moyima kumapulumutsa mabwalo ozungulira malo pamene kukula kwa toroid kukukulirakulira, koma kumapangitsa kuti pakhale vuto la kutalika kwa gawo. Kuyika moyima kumakwezanso gawo lapakati pa mphamvu yokoka ndikupangitsa kuti lisagwedezeke ndi kugwedezeka.
Kugwirizana kwa Adhesive
Kulumikiza zomatira (gluing) ndiyo njira yodziwika kwambiri yolumikizira zolumikizira ku koyilo yolowera. Wogwiritsa ntchitoyo ayenera kumvetsetsa bwino zolinga zomangirira: kaya ndikungosunga chowongolera pa koyilo kapenanso kuziziritsa kwambiri potengera kutentha kwa koyilo yozikika ndi madzi.
Mlandu wachiwiri ndi wofunikira makamaka pamakoyilo odzaza kwambiri komanso kutentha kwanthawi yayitali, monga kusanthula ntchito. Mlanduwu ndi wovuta kwambiri ndipo udzafotokozedwa mopitilira. Zomatira zosiyanasiyana zitha kugwiritsidwa ntchito kumamatira ndi ma epoxy resins kukhala zomatira zomwe zimagwiritsidwa ntchito kwambiri.
Zomatira za DeepMaterial ziyenera kukhala ndi izi:
· Mkulu adhesion mphamvu
· Good matenthedwe madutsidwe
· Kutentha kwakukulu kukana pamene malo olowa akuyembekezeka kukhala otentha. Kumbukirani kuti pakugwiritsa ntchito mphamvu zambiri madera ena amkuwa amatha kufikira 200 C kapena kupitilira apo ngakhale kuziziritsa kwamadzi kwamadzi ambiri.
