Tun da guntu inductor yana da fasali irin su ƙarami, babban inganci, babban ajiyar makamashi, da ƙarancin ƙarancin DCR, a hankali ya maye gurbin inductor na toshe na gargajiya a fagage da yawa.Yayin da masana'antun lantarki suka shiga zamanin miniaturization da flattening, guntu inductor suna ƙara amfani da su a cikin aikace-aikace masu yawa.A lokaci guda,guntu inductorskarami da karami, wanda kuma yana kawo matsaloli ga inductor na guntu.
Kariya don walda preheating
Saboda girmansa ƙanana da sirara, akwai bambance-bambance da yawa tsakanin sayar da inductor na guntu da inductor na toshe.Abin da ya kamata a biya hankali a lokacin soldering guntu inductor?
1. Kafin walda da guntu inductor, shi wajibi ne don kula da preheating don kauce wa thermal girgiza a lokacin waldi.
2. Yanayin zafin jiki na preheating yana buƙatar jinkirin tashi, zai fi dacewa 2 ℃ / sec, kuma kada ya wuce 4 ℃ / sec.
3. Lura da zafin jiki bambanci tsakanin walda zafin jiki da kuma surface zafin jiki Kullum, da zazzabi bambanci tsakanin 80 ℃ da 120 ℃ ne al'ada.
4. A lokacin walda, ya kamata a lura cewa thermal shock zai karu tare da karuwa da guntu inductor size ko zazzabi.
Solderability
Nitsewar ƙarshen fuskar guntu inductor a cikin tanderun tin a 235 ± 5 ℃ na 2 ± 1 seconds na iya samun sakamako mai kyau na siyarwa.
Amfani da juzu'i a lokacin walda
Zaɓin juyi mai dacewa na siyarwa yana taimakawa kare saman inductor.Ka lura da waɗannan abubuwan.
1. Lura cewa kada a sami acid mai ƙarfi a cikin juzu'in lokacin walda inductor na facin.Ana yawan amfani dashi don kunna rosin flux mai laushi.
2.Idan an zaɓi juzu'in ruwa mai narkewa, ya kamata a biya kulawa ta musamman ga tsabtar ma'auni kafin waldawa.
3.A kan jigo na tabbatar da kyau waldi, kula da yin amfani da kadan juyi kamar yadda zai yiwu.
Kariya don aikin walda
1.Yi amfani da reflow soldering kamar yadda zai yiwu don kauce wa sayar da hannu.
2.Note cewa kalaman soldering ba a bada shawarar ga guntu inductor girma fiye da 1812 size.Domin a lokacin da guntu inductor aka nutsar a cikin narkakkar walda kalaman, za a yi wani m zafin jiki tashin, yawanci 240 ℃, wanda zai iya haifar da lalacewar inductor saboda thermal shock.
3. Yin amfani da ƙarfe na lantarki don walda inductor na guntu bai dace sosai ba, amma yayin da ake gudanar da bincike da haɓaka aikin injiniya, ya zama dole a yi amfani da ƙarfe na lantarki don walda injin inductor da hannu.Ga abubuwa biyar da ya kamata a lura da su
(1) Preheat da kewaye da inductor zuwa 150 ℃ kafin walda da hannu
(2) The soldering iron kada ya taba guntu inductor jiki
(3) Yi amfani da ƙarfe mai 20 watts da diamita 1.0 mm
(4) The soldering baƙin ƙarfe zafin jiki ne 280 ℃
(5)Lokacin walda bazai wuce daƙiƙa uku ba
Don ƙarin bayani, da fatan za a ji daɗituntube mu.
