Purpose-built electronics transfer racks protect devices end-to-end in transit.
Quality & Methods
High precision and high repair rates with shorter cycles and no secondary damage
Online Diagnostics
Repair rate near 100%
Network modeling reproduces the operating environment to locate faults from symptoms — the mainstream method for most scenarios.
Offline Diagnostics
Repair rate about 76%
For older undocumented equipment, circuit logic and component electrical analysis pinpoint board faults to enable repair.
Expert Repair Team
Over 80% of our repair engineers have 5+ years of experience with systematic training from Cisco, Ericsson, Alcatel-Lucent, ZTE, FiberHome, Siemens, Nortel, NewBridge, RAD and others. Years of accumulated case histories form a knowledge base that keeps customer equipment running.
