Ekubeni i-chip inductors ineempawu ezifana ne-miniaturization, umgangatho ophezulu, ukugcinwa kwamandla aphezulu, kunye ne-DCR ephantsi kakhulu, ithathe indawo ye-plug-in inductors yendabuko kwiindawo ezininzi.Njengoko imboni ye-elektroniki ingena kwixesha le-miniaturization kunye ne-flattening, i-chip inductors isetyenziswa ngakumbi kuluhlu olubanzi lwezicelo.Ngaxeshanye,i-chip inductorsezincinci nezincinci, ezizisa ubunzima kwi-weld chip inductor.
Imiqathango yokutshisa i-welding
Ngenxa yobukhulu bayo obuncinci kunye nomncinci, kukho iiyantlukwano ezininzi phakathi kwe-soldering ye-chip inductors kunye ne-plug-in inductors.Yintoni ekufuneka iqwalaselwe xa i-soldering chip inductors?
1. Ngaphambi kokuba udibanise i-inductor ye-chip, kuyimfuneko ukuthobela ingqalelo kwi-preheating ukuphepha ukutshatyalaliswa kwe-thermal ngexesha le-welding.
2. Ubushushu bokufudumala bufuna ukunyuka okucothayo, ngokukhethekileyo i-2 ℃/sec, kwaye akufanele kudlule i-4 ℃/sec.
3. Qaphela umahluko weqondo lobushushu phakathi kobushushu be-welding kunye nobushushu bomphezulu Ngokubanzi, umahluko wobushushu phakathi kwe-80 ℃ kunye ne-120 ℃ uqhelekile.
4. Ngexesha le-welding, kufuneka kuqatshelwe ukuba ukutshitshiswa kwe-thermal kuya kwanda ngokunyuka kobukhulu be-chip inductor okanye ukushisa.
Solderability
Ukuntywiliselwa kwesiphelo sobuso be-chip inductor kwiziko letoti kwi-235 ± 5 ℃ kwi-2 ± 1 imizuzwana kunokufikelela kwiziphumo ezilungileyo zokubethelela.
Ukusebenzisa i-flux ngexesha le-welding
Ukukhetha i-soldering flux efanelekileyo inceda ukukhusela i-inductor surface.Phawula ezi ngongoma zilandelayo.
1.Qaphela ukuba akufuneki kubekho i-acids eqinile kwi-flux xa udibanisa i-inductor ye-patch.Iqhele ukusetyenziswa ukwenza i-mild rosin flux.
2.Ukuba i-flux e-soluble yamanzi ikhethiweyo, ingqalelo ekhethekileyo kufuneka ihlawulwe ekucocekeni kwe-substrate ngaphambi kwe-welding.
3.Kwisiseko sokuqinisekisa i-welding elungileyo, nikela ingqalelo ekusebenziseni i-flux encinci ngangokunokwenzeka.
Imiqathango yenkqubo ye-welding
1.Sebenzisa i-reflow soldering kangangoko kunokwenzeka ukunqanda i-soldering manual.
2. Qaphela ukuba i-wave soldering ayikhuthazwa kwii-chip inductors ezinkulu kunobukhulu be-1812.Kuba xa i-chip inductor intywiliselwa kwi-welding wave etyhidiweyo, kuya kubakho ukunyuka kwamaqondo obushushu asezantsi, ngokuqhelekileyo angama-240 ℃, okunokubangela umonakalo we-inductor ngenxa yokothuka kwe-thermal.
3. Ukusebenzisa i-iron soldering yombane ukuwelda i-chip inductor ayifanelekanga kakhulu, kodwa xa kuphando lobunjineli kunye nenkqubo yophuhliso, kuyimfuneko ukusebenzisa isinyithi sombane sombane kwi-weld manual i-chip inductors.Nazi izinto ezintlanu ekufuneka uziqwalasele
(1) Ukutshisa isekethe kunye ne-inductor ukuya kwi-150 ℃ ngaphambi kwe-welding ngesandla
(2)Intsimbi yokuthambisa akufuneki ichukumise umzimba we-chip inductor
(3)Sebenzisa intsimbi yokuthambisa eneewathi ezingama-20 kunye nedayamitha eyi-1.0 mm
(4)Iqondo lobushushu lentsimbi yi-280 ℃
(5) Ixesha le-welding aliyi kudlula imizuzwana emithathu
Ngolwazi oluthe kratya, nceda uzive ukhululekileQhagamshelana nathi.
