Kev tswj fais fab zoo li qub yeej ib txwm muaj kev sib tw rau cov engineers hauv kev tsim khoom siv hluav taws xob portable. Tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov xws li lub tsev txhab nyiaj fais fab thiab tag nrho-hauv-ib lub tsev txhab nyiaj fais fab, txawm tias lub ntsiab tswj IC mus pw tsaug zog, Capacitor leakage tam sim no tseem siv roj teeb lub zog, uas ua rau muaj qhov tshwm sim ntawm "tsis muaj lub zog siv hluav taws xob", uas cuam tshuam rau lub roj teeb lub neej thiab cov neeg siv khoom txaus siab ntawm cov khoom siv davhlau ya nyob twg.

- Root Cause Technical Analysis -

Lub ntsiab lus ntawm cov dej xau tam sim no yog tus cwj pwm me me ntawm cov xov xwm capacitive nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb. Nws qhov loj me yog cuam tshuam los ntawm ntau yam xws li electrolyte muaj pes tsawg leeg, electrode interface xeev, thiab txheej txheem ntim. Ib txwm ua kua electrolytic capacitors yog qhov ua rau kev ua haujlwm tsis zoo tom qab hloov qhov kub thiab qis qis lossis rov ua dua, thiab cov dej ntws tawm tam sim no. Txawm hais tias cov khoom siv hluav taws xob hauv lub xeev muaj qhov zoo, yog tias cov txheej txheem tsis zoo, nws tseem nyuaj rau kev tawg ntawm μA qib pib.

- YMIN Solution thiab Txheej Txheem Zoo -

YMIN txais cov txheej txheem dual-khiav ntawm "tshwj xeeb electrolyte + precision tsim"

Electrolyte formulation: siv high-stability organic semiconductor cov ntaub ntawv los inhibit carrier tsiv teb tsaws;

Electrode qauv: multi-layer stacking tsim los ua kom cov cheeb tsam zoo thiab txo lub zog hluav taws xob hauv tsev;

Cov txheej txheem tsim: Los ntawm kev txhawb zog ib kauj ruam dhau los, txheej txheej oxide tuab yog tsim los txhim kho qhov kev tiv thaiv hluav taws xob thiab kev tawm tsam. Tsis tas li ntawd, cov khoom lag luam tseem tswj xyuas qhov kev ruaj ntseg tam sim no tom qab reflow soldering, daws qhov teeb meem ntawm kev sib xws hauv cov khoom loj.

- Kev Tshawb Fawb Cov Ntaub Ntawv & Cov Lus Qhia Kev Ntseeg -

Cov hauv qab no yog cov ntaub ntawv xau tam sim no ntawm 270μF 25V specification ua ntej thiab tom qab reflow solderingContrast (kwv yees tam sim no: μA):

Pre-reflow xeem cov ntaub ntawv

Post-reflow test cov ntaub ntawv

- Daim ntawv thov scenarios thiab cov qauv pom zoo -

Tag nrho cov qauv yog ruaj khov tom qab reflow soldering thiab yog haum rau automated SMT ntau lawm kab.
