Kaha li-inductors tsa chip li na le likarolo tse kang miniaturization, boleng bo phahameng, polokelo e phahameng ea matla, le DCR e tlaase haholo, butle-butle e nkile sebaka sa li-inductors tsa setso sa plug-in masimong a mangata. Ha indasteri ea elektroniki e kena nakong ea miniaturization le flattening, li-inductors tsa chip li ntse li sebelisoa haholo mefuteng e mengata ea lits'ebetso. Ka nako e tšoanang,li-inductors tsa chiptse nyane le tse nyane, tse tlisang mathata ho weld chip inductor.
Litlhokomelo bakeng sa ho cheselletsa preheating
Ka lebaka la boholo ba eona bo bonyenyane le bo tšesaane, ho na le liphapang tse ngata pakeng tsa soldering ea chip inductors le plug-in inductors. Ke eng e lokelang ho lebisoa tlhokomelo ho li-inductors tsa soldering chip?
1. Pele ho welding chip inductor, hoa hlokahala hore u ele hloko preheating ho qoba mocheso oa mocheso nakong ea welding.
2. Thempereichara ea preheating e hloka ho nyoloha butle, haholo-holo 2 ℃/sec, 'me ha ea lokela ho feta 4 ℃/sec.
3. Hlokomela phapang ea mocheso pakeng tsa mocheso oa tjheseletsa le mocheso o ka holim'a metsi Ka kakaretso, phapang ea mocheso pakeng tsa 80 ℃ le 120 ℃ e tloaelehile.
4. Nakong ea welding, hoa lokela ho hlokomeloa hore mocheso oa mocheso o tla eketseha ka ho eketseha ha boholo ba chip inductor kapa mocheso.
Solderability
Ho qoelisoa ha sefahleho sa ho qetela sa chip inductor ka seboping sa thini ho 235 ± 5 ℃ bakeng sa metsotsoana e 2 ± 1 ho ka fihlela litholoana tse ntle tsa ho soasoa.
Ho sebelisa flux nakong ea welding
Ho khetha flux e loketseng ea solder ho thusa ho sireletsa bokaholimo ba inductor. Hlokomela lintlha tse latelang.
1.Hlokomela hore ha hoa lokela ho ba le li-acids tse matla ka har'a phallo ha ho tjheseletsa inductor ea patch. Hangata e sebelisoa ho kenya tšebetsong flux e bonolo ea rosin.
2.Haeba phallo e qhibilihang ka metsi e khethiloe, tlhokomelo e khethehileng e lokela ho lefshoa ho bohloeki ba substrate pele ho welding.
3.Ka lebaka la ho etsa bonnete ba hore welding e ntle, ela hloko ho sebelisa flux e nyane kamoo ho ka khonehang.
Litlhokomelo bakeng sa ts'ebetso ea welding
1.Sebelisa reflow soldering ka hohle kamoo ho ka khonehang ho qoba ho soasoa ka letsoho.
2. Hlokomela hore wave soldering ha e khothalletsoe bakeng sa li-inductors tse kholo ho feta boholo ba 1812. Hobane ha chip inductor e qoelisoa ka har'a leqhubu le entsoeng ka ho qhibilihisoa, ho tla ba le ho phahama ho hoholo ha mocheso, hangata ho 240 ℃, ho ka bakang tšenyo ea li-inductor ka lebaka la ho tsukutloa ke mocheso.
3. Ho sebelisa tšepe ea solder ea motlakase ho tjheseletsa chip inductor ha hoa lokela haholo, empa ha ho etsoa lipatlisiso tsa moenjiniere le ts'ebetso ea nts'etsopele, hoa hlokahala ho sebelisa tšepe ea motlakase ea motlakase ho kenya letsoho li-inductors tsa chip. Lintho tse hlano tseo u lokelang ho li ela hloko ke tsena
(1) Preheat potoloho le inductor ho 150 ℃ pele ho tjheseletsa ka letsoho
(2) Tšepe ea solder ha ea lokela ho ama 'mele oa chip inductor
(3) Sebelisa tšepe ea solder e nang le li-watts tse 20 le bophara ba 1.0 mm
(4) Mocheso oa tšepe ea soldering ke 280 ℃
(5) Nako ea ho cheselletsa ha e na ho feta metsotsoana e meraro
Bakeng sa lintlha tse ling, ka kopo ikutloe u lokolohile hoiteanye le rona.
