Varnix Technology Co., Ltd. operates state-of-the-art production lines certified under ISO 9001:2015. Every power inverter and DC converter undergoes rigorous raw material screening, precision SMT welding, component assembly, and 100% full-load aging tests before export dispatch.
100% incoming component verification, Tier-1 semiconductor sourcing, and RoHS-compliant inventory.
High-precision soldering stations with automated temperature profiling to eliminate dry solder joints.
High-capacity busbar and transformer soldering for heavy-current power conversion models.
Standardized ESD-safe workstations assembling MOSFETs, driver ICs, and thermal dissipators.
Precise mounting into extruded aluminum heat-sink enclosures with silicone thermal interface padding.
Wire harnessing, connector potting, and digital LCD interface integration prior to verification.
Precision evaluation of output voltage tolerance, regulation limits, and transient response under load.
Testing short-circuit protection, reverse connection safety, and over-temperature auto-recovery.
Continuous dynamic aging at 40°C–50°C elevated ambient temperature to screen early-life failures.
Multi-hour endurance run on automated programmable load racks ensuring field reliability.
Digital oscilloscope analysis checking THD (< 3%), peak voltage, and zero-crossing noise.
Laboratory digital multimeter calibration of output voltage, current sensing, and display readouts.
Controlled thermal baking for conformal coatings and moisture-proof potting compounds.
Drilling and CNC tapping equipment for custom mounting brackets and 19-inch rack frames.
Strict cosmetic checks, hi-pot insulation tests, barcode serial recording, and ground continuity tests.
Heavy-duty reinforced cartons, shock-absorbing foam inserts, and palletized sea/air shipping prep.
