I. Ambient kub
1. Qhov kub thiab txias
Qhov chaw ua haujlwm siab tshaj plaws nyob ib puag ncig ntawm lub capacitor yog qhov tseem ceeb heev rau nws daim ntawv thov.Qhov nce ntawm qhov kub thiab txias accelerates tag nrho cov tshuaj thiab cov tshuaj electrochemical, thiab cov khoom siv dielectric yog qhov yooj yim rau hnub nyoog.Kev pabcuam lub neej ntawm lub capacitor txo qis nrog qhov nce ntawm qhov kub thiab txias.Lub capacitance hloov nrog qhov nce ntawm qhov kub thiab txias yog nyob ntawm kev sib raug zoo ntawm dielectric tas li thiab kub, nrog qhov zoo kub coefficient uas yog, lub peev xwm nce nrog kub, nrog qhov kub tsis zoo coefficient muaj peev xwm txo qis nrog qhov kub thiab txias.
Raws li qhov kub thiab txias, cov khoom siv hluav taws xob nce, yog li cov rwb thaiv tsev tsis kam txo nrog qhov kub thiab txias.Lub zog dielectric kuj tseem txo qis nrog qhov nce ntawm qhov kub thiab txias, yog li qhov kev khiav hauj lwm voltage yuav tsum tau txo qis thaum qhov kev pabcuam siab kub nce.Kev kub siab ua rau cov hlau oxidation, tiv thaiv kev tiv thaiv, kev tiv thaiv nce thiab poob nce.
2. Qhov kub thiab txias
Cov khoom ua nkig, epoxy resin tawg thiab poob nws cov nyhuv tiv thaiv.Cov hluav taws xob kev ua tau zoo ntawm lub capacitor yog degraded los ntawm noo noo infiltration.
3. Qhov kub thiab txias cuam tshuam
Cov thermal expansion thiab contraction sai ua rau kev ntxhov siab sab hauv, tsim alternating condensation, khov thiab evaporation, kom lub encapsulation txheej cracking, cracking ua rau dej vapor infiltration, accelerate qhov kev ua tau zoo ntawm lub capacitor deteriorates.
II.Humid ib puag ncig
1. Cov av noo siab
Dej vapor condenses rau saum npoo ntawm lub capacitor, thiab yog absorbed, yog li ntawd lub rwb thaiv tsev tsis kam ntawm lub capacitor txo, thiab muaj to thiab arc ya.Lub dielectric tsis tu ncua nce thiab qhov dielectric poob nce.Thaum cov dej vapor nkag mus rau sab hauv metallized txheej ntawm lub capacitor, lub peev xwm yuav txo qis thiab qhov poob yuav nce.
2. Hloov kub thiab av noo
Cov dej vapor yog absorbed thiab diffused rau saum npoo ntawm lub capacitor.Kev ua pa thiab condensation ntawm cua sov tuaj yeem ua kom cov dej vapor nkag mus rau hauv lub capacitor sab hauv thiab ua rau kev ua haujlwm ntawm lub capacitor deteriorate raws li tau hais los saum no.
Nyob rau tib qhov txheeb ze cov av noo, thaum qhov kub thiab txias, cov dej molecules nce thiab tsim cov molecular khoob yog nrawm.Cov dej molecules tuaj yeem nkag mus rau cov khoob no los ntawm cov huab cua ib puag ncig thiab yog li nkag mus rau hauv nruab nrab.
Nyob rau tib qho av noo, qhov kub qis dua, qhov siab dua qhov txheeb ze av noo, qhov dej noo ntau dua lub capacitor absorbs.
III.Dynamic ib puag ncig
Kev vibration, kev cuam tshuam thiab kev nrawm yog lub ntsiab dynamic ib puag ncig, uas tuaj yeem ua rau lub capacitor puas lossis puas los ntawm covSMT tshuabthiab lwm yam machinery, thiab cov capacitance hloov vim me me hloov ntawm capacitor qauv.Tsis tas li ntawd, nws yuav ua rau cov hlau lead tawg, kev sib cuag tsis zoo thiab lwm yam tshwm sim.
IV.Tsawg siab ib puag ncig
Capacitors yog siv nyob rau hauv high-altitude ib puag ncig.Nrog rau qhov nce ntawm qhov siab, huab cua siab txo qis thiab hluav taws xob tsis kam ntawm huab cua txo.Lub capacitor yuav tsim arc thiab corona tshwm sim, thiab qhov voltage ntawm lub capacitor yuav txo qis.Tsis tas li ntawd, huab cua nyias yog qhov nyuaj rau cua sov.Qhov kub nce ntawm lub capacitor yuav nce.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom.Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, coj kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.Peb ntseeg tias cov neeg zoo thiab cov neeg koom tes ua rau NeoDen lub tuam txhab zoo thiab peb txoj kev cog lus. rau Innovation, Diversity thiab Sustainability xyuas kom meej tias SMT automation nkag mus tau rau txhua tus neeg nyiam nyiam nyob txhua qhov chaw.
