ʻO kaʻoiaʻiʻo, he mea koʻikoʻi ka soldering i ka hana ʻana i nā inductors, akā ʻaʻole i nānā nui ʻia.He mea pono loa iā mākou ke hoʻololi i nā ala kūpono e hoʻopaʻa ai i nā inductors ʻeha SMD e hōʻoia i ka ikaika o kā mākou hana inductor.I kēia manawa, e kaʻana aku au iā ʻoe i nā kumu he nui no ke kūʻai ʻole ʻana oSMD wili inductor, manaʻolana e kōkua iā ʻoe.

1. Oxidation a i ʻole nā ​​mea ʻē ma ka inductor soldering pad

ʻO ke kūʻai maikaʻi ʻole ʻana o nā mea hōʻeha SMD, oxidation a i ʻole nā ​​​​mea ʻē aʻe ma ka pad inductor ke kumu maʻamau e hoʻohaumia ʻole ai i nā inductors like ʻole.

2. Aia ka burr ma ka pā hao o SMD inductor

Aia kahi kaʻina ʻoki wāwae i ka hana ʻana o ka SMD inductor.Ma kēia kaʻina hana, inā ʻaʻole mālama maikaʻi ʻia ka mea ʻokiʻoki, maʻalahi ke kumu i ka burr ma ka pā hao inductor.I kēia hihia, e hoʻopiʻi ʻole ʻia ka hoʻopili ʻana o ka inductor, ka hopena i ka wiliwili maikaʻi ʻole.

3. ʻAʻole kūlike ka wāwae kulou o ka SMD inductor soldering pad

Ma lalo o nā kūlana maʻamau, pono e hoʻopili piha ʻia nā pads ma nā ʻaoʻao ʻelua o ka inductor i ka solder paste o ka papa PCB.Eia nō naʻe, inā ʻaʻole i hoʻopololei ʻia nā pads inductor i ka wā o ke kuʻi wāwae ʻana, e hoʻoneʻe ʻia ka hopena o ka inductor, e hopena i ka maikaʻi ʻole.

4. He hohonu loa ka awāwa kino inductor

Aia ʻelua mau ʻāpana ma ke kino inductor SMD.ʻO kēia mau awāwa ʻelua ke kūlana ma hope o ke kūlou ʻana o ka pine inductor pad.Eia nō naʻe, inā hohonu loa ka inductance groove, ʻoi aku ka nui ma mua o ka mānoanoa o ka pepa pad, ʻoiai ua paʻa ka inductor i ka papa PCB, ua hoʻokuʻu ʻia ka inductance pad a ʻaʻole pili me ka solder paste, e hopena i ka maikaʻi ʻole. .

5. Nā pilikia i ka hana hana mea kūʻai

ʻAʻole wale ka pilikia o ka inductor ponoʻī i ke kūʻai ʻana i ka SMD inductor.I nā hihia he nui, ma muli o nā pilikia o ke kaʻina hana o ka mea kūʻai aku, e alakaʻi pū ia i ka ilihune soldering o ka inductor, e like me ka haʻahaʻa solder paste hoʻihoʻi wela a me ka lawa ʻole reflow soldering wela.

Pono e noʻonoʻo nui ʻia i nā pilikia i luna ma ke kaʻina hana kuʻi ʻana o SMD winding inductor e hōʻemi i nā mea i makemake ʻole ʻia i ke kaʻina hana kuʻi.

Inā makemake ʻoe, e ʻoluʻolu e ʻoluʻolukāhea iā mā˚ouno na ninau hou aku.
