Ihe na-akpata ọdịda inductor

1. Nrụgide ígwè ọrụ nke magnetik core na-emepụta na usoro nhazi dị ukwuu ma ahapụbeghị ya.

2. E nwere adịghị ọcha na magnetik isi ma ọ bụ oghere magnetik isi ihe n'onwe ya abụghị edo, nke na-emetụta ọnọdụ magnetik nke magnetik isi na deviates permeability nke magnetik isi.

3. N'ihi mgbawa na-agbawa mgbe agbachara.

5. Waya ọla kọpa dị gịrịgịrị, nke na-ebute ịgbado ọkụ ụgha na ọdịda sekit na-emeghe mgbe ejikọtara ya na eriri ọla kọpa.

Ụdị ịgbado ọkụ

Inductance nke inductor ike kwachie obere ugboro na-abawanye site na ihe na-erughị 20% mgbe reflow reflow.

Demagnetization na-eme n'ihi na okpomọkụ nke reflow soldering karịrị Curie okpomọkụ nke obere ugboro kwachie ihe inductor. Mgbe demagnetization nke patch inductor, permeability nke patch inductor ihe na-alaghachi na nke kachasị na inductance na-abawanye. Usoro njikwa n'ozuzu bụ na inductance na-abawanye site na ihe na-erughị 20% mgbe onye na-emepụta ihe na-eguzogide ọgwụ ịgbado ọkụ.

Nsogbu na solder iguzogide nwere ike ịkpata bụ na mgbe ụfọdụ sekit arụmọrụ bụ niile ruru eru na obere ogbe ntuziaka ịgbado ọkụ (mgbe patch inductor na-adịghị kpụ ọkụ n'ọnụ n'ozuzu, inductance na-abawanye ubé). Otú ọ dị, mgbe enwere ọnụ ọgụgụ buru ibu nke ibe, a na-achọpụta na arụmọrụ nke sekit ụfọdụ na-eweda ya ala. Nke a nwere ike ịbụ n'ihi mmụba nke inductance nke patch mgbe reflow soldering, na-emetụta arụmọrụ nke sekit. N'ebe a na-achọsi ike izi ezi nke inductance mgbawa (dị ka mgbama ịnata na sekit na-ebufe), ekwesịrị itinye nlebara anya karịa na nguzogide ịgbado ọkụ nke mgbawa inductor.

Mgbe okpomọkụ nke reflow soldering ruru, metal ọlaọcha na-emeghachi omume na tin metal na-etolite eutectic, n'ihi ya, tin enweghị ike plated ozugbo na ọlaọcha ọgwụgwụ nke patch inductor. Kama nke ahụ, a na-ebu ụzọ techie ngwucha ọlaọcha ahụ na nickel ka ọ bụrụ oyi akwa mkpuchi, ma tinyezie tin.

1. Ọgwụgwụ oxidation:

Mgbe oke okpomọkụ, iru mmiri, kemịkalụ, ikuku oxidizing, ma ọ bụ chekwaa ya ogologo oge na-emetụta ihe nkedo ahụ, igwe Sn dị na njedebe inductor nke patch ahụ na-agbanye na SnO2, na njedebe inductor nke patch na-aghọ ọchịchịrị. N'ihi na SnO2 anaghị etolite eutectic na Sn, Ag, Cu, wdg, nrụnye nke inductance patch na-ebelata. Ndụ shelf nke ngwaahịa inductor patch: ọkara afọ. Ọ bụrụ na njedebe inductance nke patch ahụ metọọ, dị ka ihe na-ejupụta mmanụ, ihe mgbaze, wdg, ọ ga-emekwa ka ọ daa n'ibe.

2. Ihe mkpuchi nickel dị oke mkpa:

Ọ bụrụ na nickel plating, nickel oyi akwa dị gịrịgịrị ịrụ ọrụ nke iche. N'oge reflow soldering, Sn na njedebe inductor nke patch na-emeghachi omume na Ag nke ya nke mbụ, nke na-emetụta nchikota nke Sn na njedebe inductor nke patch na mado na-ere ihe na pad ahụ, na-ebute ọdịdị nke iri nri. ọlaọcha na mbelata nke solderability nke patch inductor.

Usoro ikpe: gbanye inductor patch n'ime ite a wụrụ awụ maka sekọnd ole na ole wee wepụ ya. Ọ bụrụ na a na-achọta oghere ndị ahụ na njedebe, ma ọ bụ ọbụna na-ekpuchi ahụ nke poselin ahụ, enwere ike ikpebi na e nwere ihe dị iche iche nke iri ọlaọcha.

3. Ịgbado ọkụ adịghị mma:

Ọ bụrụ na ngwaahịa inductor patch nwere nrụrụ na-ehulata, a ga-enwe mmetụta mmụba n'oge ịgbado ọkụ. Mgbado ọkụ na-adịghị mma, ịgbado ọkụ ụgha, imewe mpe mpe akwa na-ekwesịghị ekwesị.

a. Ekwesịrị ịmebe njedebe abụọ nke pad ahụ iji zere nha dị iche iche, ma ọ bụghị na oge ịgbaze na ike wetting nke njedebe abụọ ahụ ga-adị iche.

b. The ịgbado ọkụ ogologo bụ n'elu 0.3mm (ya bụ, ndakọrịta ogologo nke metal ọgwụgwụ nke patch inductor na mpe mpe akwa).

c. Ogologo mpempe akwụkwọ ahụ dị obere ka o kwere mee, n'ozuzu ọ bụghị ihe karịrị 0.5mm.

d. Obosara nke mpe mpe akwa n'onwe ya ekwesịghị ịdị oke oke, yana obosara ezi uche ya ekwesịghị ịfe 0.25mm ma e jiri ya tụnyere obosara nke MLCI.

Mgbe inductance patch gbanwere akụkụ θ n'ihi pad na-akwụghị ọtọ ma ọ bụ tapawa ihe na-ere ere. N'ihi ike wetting na-emepụta n'oge agbaze nke ịgbado ọkụ na mpe mpe akwa, enwere ike ịmepụta ọnọdụ atọ ndị a dị n'elu, nke na-emezi onwe ya bụ isi, ma mgbe ụfọdụ, a na-adọta ya karịa, ma ọ bụ otu isi ihe na-adọta, na inductor patch bụ. dọtara na mpe mpe akwa, ma ọ bụ ọbụna welie elu. Oblique ma ọ bụ kwụ ọtọ (ihe ncheta). Ka ọ dị ugbu a, igwe ntinye na θ angle offset nlele anya nwere ike ibelata ihe omume nke ụdị ọdịda a.

Ọ bụrụ na akara ugbu a nke mgbawa inductor mgbawa ahọpụtara dị ntakịrị, ma ọ bụ ọ bụrụ na enwere nnukwu mkpali ugbu a na sekit, nke ugbu a ga-ere ọkụ na mgbawa mgbawa ma ọ bụ ihe ndọta ga-ada, na-ebute sekit mepere emepe. Wepu inductor patch na bọọdụ sekit maka nnwale, ihe nrụnye ahụ na-ada ada, na mgbe ụfọdụ enwere ihe ịrịba ama nke ike ọgwụgwụ. Ọ bụrụ na ọkụ dị ugbu a emee, ọnụ ọgụgụ nke ngwaahịa dara ada ga-adịwanye ukwuu, na ngwaahịa ndị dara ada n'otu batch ga-erukarị karịa 100%.

Ngwa ngwa jụrụ oyi na kpo oku n'oge reflow soldering na-akpata nrụgide dị n'ime nke inductor patch, nke na-eduga n'ịbawanye ntụpọ nke obere akụkụ nke patch inductor nke nwere ihe egwu zoro ezo nke oghere oghere, na-ebute oghere nke oghere nke oghere. inductor kwachie. Wepu inductor patch na bọọdụ sekit iji nwalee, inductor patch adịghị mma. Ọ bụrụ na e nwere sekit mepere emepe ịgbado ọkụ, ọnụ ọgụgụ nke ngwaahịa dara ada na-adịkarị obere, na ngwaahịa ndị dara ada n'otu ogbe na-adịkarị obere karịa 1000 akara ule.

Ike ndọta

Ahụ seramiiki esighi ike ma na-akụrikasị n'ihi nrụrụaka adịghị mma nke inductor patch ma ọ bụ ihe ndị ọzọ, ma ọ bụ ahụ mebiri emebi mgbe ike mpụga metụtara ngwaahịa ahụ.

Adhesion ike

Ọ bụrụ na adhesion nke ọlaọcha oyi akwa nke inductor njedebe nke kwachie adịghị mma, mgbe reflow soldering, inductor nke patch bụ oyi na-ekpo ọkụ, na-akpata nrụgide nke thermal mgbasa na oyi shrinkage, na poselin ahụ na-emetụta site na mpụga ike. , ọ ga-ekwe omume ime ka nkewa na ịwụfu njedebe nke inductor na ahụ poselin; ma ọ bụ na mpe mpe akwa ahụ buru ibu, na mgbe reflow soldering, ike wetting nke site na tapawa agbaze na njedebe mmeghachi omume dị ukwuu karịa njedebe adhesion, na-ebute njedebe njedebe.

Inductor patch na-ere ọkụ ma ọ bụ na-ere ọkụ raw, ma ọ bụ enwere obere mgbawa na usoro nrụpụta. Ngwa ngwa jụrụ oyi na kpo oku n'oge ire ere na-ebugharị na-akpata nchekasị n'ime ihe nrụnye ihe nkedo, mgbawa kristal, ma ọ bụ mgbasa micro-crack, na-ebute mmebi magnet na ihe ndị ọzọ.
