A haƙiƙanin gaskiya, soldering mataki ne mai matuƙar mahimmanci wajen samar da inductor, amma wanda ba a kula da shi sosai. Yana da matukar mahimmanci a gare mu mu daidaita hanyoyin da suka dace don walda inductor raunuka na SMD don tabbatar da cewa aikin inductor ɗinmu ya fi ƙarfi. Yanzu zan raba tare da ku da dama dalilai na matalauta soldering naSMD mai iska inductor, da fatan in taimake ku.

1. Oxidation ko na waje al'amarin a kan inductor soldering kushin

Rashin ƙarancin siyar da inductor rauni na SMD, iskar shaka ko al'amuran waje akan kushin inductor shine dalilin gama gari wanda ke haifar da ƙarancin siyar da inductor iri-iri.

2. Akwai burar akan kushin sayar da inductor SMD

Akwai tsarin yanke kafa a cikin samar da inductor na SMD. A cikin wannan tsari, idan mai yanke ba a kiyaye shi da kyau ba, yana da sauƙi don haifar da burr a kan kushin inductor soldering. A wannan yanayin, shi ma zai haifar da m haɗe-haɗe na inductor, haifar da matalauta waldi.

3. Ƙafafun lanƙwasawa na SMD inductor soldering pad ba daidai ba ne

A karkashin yanayi na al'ada, ya kamata a haɗa pads a ƙarshen inductor gaba ɗaya zuwa manna solder na allon PCB. Duk da haka, idan ba a lanƙwasa inductor ɗin yadda ya kamata ba yayin aikin lanƙwasawa, hakan zai sa ƙarshen inductor ɗin ya lalace, wanda zai haifar da rashin walda.

4. Inductor jiki tsagi yayi zurfi sosai

Akwai tsagi guda biyu akan jikin inductor SMD. Waɗannan tsagi guda biyu sune matsayi bayan an lanƙwasa fil ɗin inductor. Duk da haka, idan inductor tsagi ya yi zurfi sosai, wanda ya fi kauri na takarda, duk da cewa inductor yana da lebur a haɗe zuwa allon PCB, an dakatar da kushin inductance kuma baya tuntuɓar man na'urar, wanda ya haifar da rashin walƙiya mara kyau. .

5. Matsaloli a cikin tsarin samar da abokin ciniki

Rashin siyar da inductor na SMD ba shine kawai matsalar inductor kanta ba. A lokuta da yawa, saboda matsalolin tsarin masana'antu na abokin ciniki, hakanan zai haifar da rashin kyawun siyar da inductor, kamar ƙarancin mai siyarwar dawo da zafin jiki da ƙarancin reflow soldering.

Ya kamata a mai da hankali kan matsalolin da ke sama a cikin tsarin walda na inductor na SMD don rage abubuwan da ba a so a cikin aikin walda.

Idan kuna sha'awar, da fatan za a ji daɗituntube mudon ƙarin tambayoyi.
