Txij li cov nti inductors muaj cov yam ntxwv xws li miniaturization, zoo, siab zog cia, thiab tsis tshua muaj DCR, nws tau maj mam hloov cov tsoos plug-in inductors hauv ntau qhov chaw. Raws li kev lag luam hluav taws xob nkag mus rau lub sijhawm ntawm miniaturization thiab flattening, nti inductors tau siv ntau dua hauv kev siv ntau dua. Tib lub sijhawm,nti inductorsme me thiab me me, uas kuj coj teeb meem rau weld nti inductor.
Kev ceev faj rau welding preheating
Vim nws qhov me me thiab nyias nyias, muaj ntau qhov sib txawv ntawm qhov sib txawv ntawm cov chip inductors thiab plug-in inductors. Dab tsi yuav tsum tau them sai sai rau thaum soldering nti inductors?
1. Ua ntej welding lub nti inductor, nws yog ib qho tsim nyog yuav tau xyuam xim rau preheating kom tsis txhob thermal shock thaum vuam.
2. Lub preheating kub yuav tsum tau nce qeeb, nyiam dua 2 ℃ / sec, thiab nws yuav tsum tsis pub tshaj 4 ℃ / sec.
3. Nco ntsoov qhov sib txawv ntawm qhov kub thiab txias ntawm qhov vuam thiab qhov kub ntawm qhov chaw Feem ntau, qhov kub sib txawv ntawm 80 ℃ thiab 120 ℃ yog qhov qub.
4. Thaum lub sij hawm vuam, nws yuav tsum tau muab sau tseg tias thermal shock yuav nce nrog qhov nce ntawm cov nti inductor loj lossis kub.
Solderability
Immersion ntawm lub ntsej muag kawg ntawm lub nti inductor rau hauv lub cub tawg ntawm 235 ± 5 ℃ rau 2 ± 1 vib nas this tuaj yeem ua tiav cov txiaj ntsig zoo.
Siv flux thaum vuam
Xaiv qhov tsim nyog soldering flux pab tiv thaiv inductor nto. Nco ntsoov cov ntsiab lus hauv qab no.
1.Nco ntsoov tias yuav tsum tsis muaj cov kua qaub uas muaj zog hauv cov flux thaum vuam cov inductor ntawm thaj. Nws yog feem ntau siv los ua kom mob me me rosin flux.
2.Yog dej-soluble flux raug xaiv, tshwj xeeb yuav tsum tau them rau kev huv ntawm substrate ua ntej vuam.
3.Nyob rau hauv lub hauv paus ntawm kev ua kom zoo welding, xyuam xim rau kev siv me me flux li sai tau.
Kev ceev faj rau txheej txheem vuam
1.Siv reflow soldering kom ntau li ntau tau kom tsis txhob phau ntawv soldering.
2.Nco ntsoov tias yoj soldering tsis pom zoo rau nti inductors loj dua 1812 loj. Vim hais tias thaum lub nti inductor yog immersed nyob rau hauv ib tug molten vuam yoj, yuav muaj ib tug ntxhab kub nce, feem ntau 240 ℃, uas yuav ua rau inductor puas vim thermal shock.
3. Siv cov hluav taws xob soldering hlau los vuam cov nti inductor yog tsis tsim nyog, tab sis thaum nyob rau hauv engineer kev tshawb fawb thiab kev loj hlob txheej txheem, nws yog tsim nyog los siv ib tug hluav taws xob soldering hlau rau phau ntawv weld lub nti inductors. Nov yog tsib yam uas yuav tsum nco ntsoov
(1) Preheat lub Circuit Court thiab inductor rau 150 ℃ ua ntej vuam manually
(2) Cov hlau nplaum yuav tsum tsis txhob kov lub nti inductor lub cev
(3) Siv cov hlau soldering nrog 20 watts thiab 1.0 hli txoj kab uas hla
(4) Qhov kub ntawm cov hlau yog 280 ℃
(5) Lub sijhawm vuam yuav tsum tsis pub tshaj peb vib nas this
