Cov khoom siv hluav taws xob cuav tau dhau los ua qhov mob tseem ceeb hauv kev lag luam tiv thaiv.Hauv kev teb rau cov teeb meem tseem ceeb ntawm kev ua tsis zoo ntawm cov khoom tsis zoo thiab cov khoom cuav, qhov chaw sim no muab kev tshuaj xyuas lub cev puas tsuaj (DPA), kev txheeb xyuas cov khoom cuav thiab cov khoom cuav, kev tshuaj ntsuam xyuas qib, thiab kev tshuaj ntsuam xyuas tsis ua haujlwm los ntsuas qhov zoo. ntawm cov khoom, tshem tawm cov khoom tsis tsim nyog, xaiv cov khoom muaj kev ntseeg siab, thiab nruj me ntsis tswj cov khoom zoo.
Electronic Cheebtsam kuaj cov khoom
01 Kev Ntsuas Lub Cev Muaj Zog (DPA)
Txheej txheem cej luam ntawm DPA Analysis:
DPA tsom xam (Kev Tshawb Fawb Lub Cev Muaj Zog) yog ib qho kev ntsuam xyuas lub cev tsis muaj kev puas tsuaj thiab kev puas tsuaj thiab kev soj ntsuam uas siv los txheeb xyuas seb tus qauv tsim, qauv, cov khoom siv, thiab kev tsim khoom ntawm cov khoom siv hluav taws xob zoo li cas raws li cov kev cai tshwj xeeb rau lawv cov kev npaj siv.Cov qauv tsim nyog raug xaiv los ntawm cov khoom tiav batch ntawm cov khoom siv hluav taws xob rau kev tshuaj xyuas.
Lub Hom Phiaj ntawm Kev Xeem DPA:
Tiv thaiv tsis ua hauj lwm thiab zam kev txhim kho cov khoom nrog pom tseeb lossis muaj peev xwm tsis xws luag.
Txiav txim siab qhov sib txawv thiab cov txheej txheem tsis xws luag ntawm cov khoom tsim khoom hauv kev tsim thiab kev tsim khoom.
Muab cov lus pom zoo ua batch thiab txhim kho kev ntsuas.
Tshawb xyuas thiab txheeb xyuas qhov zoo ntawm cov khoom siv (ib feem ntawm kev kuaj xyuas qhov tseeb, kho dua tshiab, kev ntseeg siab, thiab lwm yam)
Cov khoom siv ntawm DPA:
Cheebtsam (chip inductors, resistors, LTCC Cheebtsam, nti capacitors, relays, keyboards, connectors, thiab lwm yam)
Cov khoom siv tsis sib xws (diodes, transistors, MOSFETs, thiab lwm yam)
Cov khoom siv microwave
Integrated chips
Qhov tseem ceeb ntawm DPA rau kev yuav khoom thiab kev ntsuas kev hloov pauv:
Ntsuam xyuas cov khoom los ntawm cov txheej txheem sab hauv thiab cov txheej txheem kev xav kom ntseeg tau tias lawv muaj kev ntseeg siab.
Lub cev zam kev siv cov khoom kho dua tshiab lossis cov khoom cuav.
DPA tsom xam tej yaam num thiab cov txheej txheem: Daim ntawv thov tiag tiag
02 Kev kuaj xyuas qhov tseeb thiab cuav
Kev txheeb xyuas cov khoom cuav thiab cuav (nrog rau kev kho dua tshiab):
Kev sib xyaw DPA txoj kev tsom xam (ib nrab), kev tshuaj xyuas lub cev thiab tshuaj lom neeg ntawm cov khoom siv los txiav txim siab txog cov teeb meem ntawm kev dag thiab kev kho dua tshiab.
Cov khoom tseem ceeb:
Cheebtsam (capacitors, resistors, inductors, thiab lwm yam)
Cov khoom siv tsis sib xws (diodes, transistors, MOSFETs, thiab lwm yam)
Integrated chips
Cov txheej txheem kuaj:
DPA (ib nrab)
Solvent test
Kev xeem ua haujlwm
Kev txiav txim siab zoo yog ua los ntawm kev sib txuas peb txoj kev sim.
03 Application-level Component Testing
Application-level analysis:
Engineering daim ntawv thov kev tshuaj ntsuam xyuas yog ua los ntawm cov khoom uas tsis muaj teeb meem ntawm qhov tseeb thiab kev kho dua tshiab, feem ntau yog tsom rau kev tsom xam ntawm qhov kub tsis kam (txheej txheej) thiab solderability ntawm cov khoom.
Cov khoom tseem ceeb:
Tag nrho cov khoom
Cov txheej txheem kuaj:
Raws li DPA, kev ua pov thawj cuav thiab kho dua tshiab, nws feem ntau suav nrog ob qhov kev xeem hauv qab no:
Cheebtsam reflow xeem (cov hlau lead-dawb reflow tej yam kev mob) + C-SAM
Cov khoom siv solderability test:
Wetting balance method, me me solder pot immersion method, reflow method
04 Component Failure Analysis
Cov khoom siv hluav taws xob tsis ua haujlwm yog hais txog qhov ua tiav lossis ib feem poob ntawm kev ua haujlwm, qhov ntsuas tsis sib xws, lossis qhov tshwm sim tsis sib xws ntawm cov xwm txheej hauv qab no:
Bathtub nkhaus: Nws hais txog kev hloov pauv ntawm kev ntseeg tau ntawm cov khoom thaum lub sij hawm tag nrho nws lub neej voj voog txij thaum pib mus rau qhov tsis ua hauj lwm.Yog hais tias qhov tsis ua hauj lwm tus nqi ntawm cov khoom yog coj raws li tus yam ntxwv tus nqi ntawm nws kev ntseeg, nws yog ib tug nkhaus nrog lub sij hawm siv raws li lub abscissa thiab tsis ua hauj lwm tus nqi raws li lub ordinate.Vim tias qhov nkhaus siab ntawm ob qho kawg thiab qis hauv nruab nrab, nws zoo li lub dab da dej, yog li lub npe "bathtub nkhaus."
