FAQ
Q: Dab tsi siab -voltage hloov tshuab siv nyob rau hauv lub tshuab hluav taws xob los xyuas kom meej synchronization?
A: Peb siv high-kev ua tau zoo SF6 roj peb-electrode trigger keyboards kom ntseeg tau tias synchronization nrog qhov sib txawv ntawm tsawg dua 100 ns rau txhua theem tawm.
Q: Dab tsi yog qhov kev tso tawm ib nrab (PD) ntawm lub tshuab hluav taws xob?
A: Ib feem ntawm qhov tso tawm (PD) qib yog tswj hwm nruj me ntsis rau <5 pC ntawm qhov ntsuas hluav taws xob, ua kom ntseeg tau ntev - lub sijhawm rwb thaiv tsev.
Q: Dab tsi yog cov kauj ruam hauv kev hloov kho?
A: Requirement confirmation -> Technical solution design -> Customer review -> Contract signing -> Manufacturing -> Factory inspection ->Kev xa khoom thiab kev teeb tsa.
Q: Dab tsi yog lub voj voog ntau lawm rau cov khoom lag luam customized?
A: Cov txheej txheem ntau lawm rau cov khoom lag luam customized feem ntau yog 8 mus rau 12 lub lis piam, nrog rau lub sijhawm tshwj xeeb raws li daim ntawv cog lus cog lus.
Q: Hom ntim twg yog siv los xyuas kom muaj kev nyab xeeb kev thauj mus los?
A: Peb siv cov ntoo ruaj khov (kev kho fumigated) thiab ya raws - pov thawj, poob siab - absorbing sab hauv linings rau ntau - txheej ntim, kom ntseeg tau tias cov khoom tsis puas thaum lub sij hawm hiav txwv los yog huab cua.
