Sezvo chip inductors ine zvinhu zvakaita se miniaturization, mhando yepamusoro, yakakwirira simba rekuchengetedza, uye yakanyanya kuderera DCR, zvishoma nezvishoma yakatsiva echinyakare plug-in inductors muminda yakawanda. Sezvo iyo indasitiri yemagetsi ichipinda munguva yeminiaturization uye flattening, chip inductors vari kuwedzera kushandiswa muhuwandu hwakawanda hwekushandisa. Panguva imwe,chip inductorszvidiki uye zvidiki, izvo zvinounzawo matambudziko ku weld chip inductor.
Chengetedzo yewelding preheating
Nekuda kwehukuru hwayo hudiki uye hutete, kune misiyano mizhinji pakati pekutengesa kwechip inductors uye plug-in inductors. Chii chinofanira kutariswa kana soldering chip inductors?
1. Usati waputira chip inductor, zvakakosha kubhadhara kune preheating kuti udzivise kupisa kwekushisa panguva yekuputika.
2. Kupisa kwekutanga kunoda kukwira zvishoma nezvishoma, zvichida 2 ℃/sec, uye haifaniri kudarika 4 ℃/sec.
3. Cherechedza musiyano wetembiricha pakati petembiricha yewelding uye tembiricha yepasi Kazhinji, musiyano wetembiricha uri pakati pe80 ℃ ne120 ℃ wakajairika.
4. Panguva yekuputika, inofanira kuonekwa kuti kupisa kwekushisa kuchawedzera nekuwedzera kwehukuru hwe chip inductor kana kutonhora.
Solderability
Kunyudzwa kwekupedzisira kwechiso che chip inductor muchoto cherata pa235 ± 5 ℃ kwemasekonzi maviri ± 1 kunogona kuwana mhedzisiro yakanaka yekusodha.
Kushandisa flux panguva welding
Kusarudza yakakodzera solder flux inobatsira kuchengetedza inductor pamusoro. Cherechedza pfungwa dzinotevera.
1.Cherechedza kuti hapanofanira kuva nemaasidhi akasimba mumhepo inoputika kana welding inductor yechigamba. Inowanzo shandiswa kumisa mild rosin flux.
2.Kana mvura-inogadziriswa flux yakasarudzwa, kunyanya kukoshesa kunofanira kubhadharwa kune utsanana hwe substrate musati welding.
3.Pamusoro pekusimbisa welding yakanaka, teerera kushandisa sediki flux sezvinobvira.
Chengetedzo yekugadzira welding process
1.Shandisa reflow soldering zvakanyanya sezvinobvira kudzivisa manual soldering.
2.Cherechedza kuti wave soldering haikurudzirwe kune chip inductors yakakura kupfuura 1812 saizi. Nekuti kana iyo chip inductor ichinyudzwa mune yakanyungudutswa welding wave, pachave nekukwira kwetembiricha yekukwira, kazhinji 240 ℃, izvo zvinogona kukonzera kukuvara kweinductor nekuda kwekuvhunduka kwekupisa.
3. Kushandisa simbi yemagetsi yekushongedza iyo chip inductor haina kunyatsokodzera, asi kana injinjiniya tsvakurudzo uye nzira yekuvandudza, zvinodikanwa kushandisa simbi yemagetsi solder to manual weld the chip inductors. Hezvino zvinhu zvishanu zvekucherechedza
(1) Preheat dunhu uye inductor kusvika 150 ℃ usati waiswa welding
(2) Simbi yekusimbisa haifanire kubata chip inductor muviri
(3)Shandisa iron soldering ine 20 watts uye 1.0 mm dhayamita
(4) Tembiricha yesimbi yekunyungudutsa i280 ℃
(5) Nguva yewelding haifaniri kudarika masekonzi matatu
Kuti uwane rumwe ruzivo, ndapota inzwa wakasununguka kutaura nesu.
Nguva yekutumira: Mar-21-2023
