SEMIKRON Equipment We Repair — By Category
SEMIKRON Product Lines We Repair
Our engineers are trained on the full SEMIKRON product range. Below are the major product families we service.
SKiM - Semikron Intelligent Module
Integrated IGBT and diode power modules with built-in gate drivers for AC drive applications. Common failures include gate driver IC degradation, thermal cycling cracks in solder joints, and IGBT gate oxide breakdown under electrical stress or contamination.
PressFit Power Modules
High-current IGBT and diode modules using press-fit technology for thyristor replacement in industrial rectifier and inverter circuits. Typical faults include bond wire lift-off, solder voids on direct copper bonded (DCB) substrates, and thermal runaway due to improper cooling.
SemiX - Power Stacks
Compact semiconductor stacks combining multiple switching stages for medium-voltage DC link drives. Common issues involve capacitor bank degradation, gate signal cross-coupling, and phase-leg short circuits from moisture ingress or ESD damage.
Diode Stacks & Rectifier Modules
Three-phase power diode assemblies and bridge rectifiers for welding, industrial furnaces, and traction systems. Failure modes include junction leakage due to thermal stress, mechanical damage from vibration, and case isolation breakdown.
Gate Driver & Control Electronics
Specialized gate driver boards and controller cards for SEMIKRON modules. Defects include optocoupler failure, power supply voltage rail collapse, and PWM signal distortion affecting switching timing.

Common SEMIKRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SEMIKRON equipment arriving at our workshop.
- ✓IGBT gate oxide breakdown and leakage — Electrical overstress from voltage spikes, contamination in the gate oxide layer, or cumulative damage from repeated switching cycles at elevated junction temperatures. SEMIKRON modules operating in harsh environments (foundries, cement plants) are vulnerable.
- ✓Solder joint cracking and bond wire lift-off — Thermal cycling stress from rapid on/off switching, inadequate heatsink contact, or manufacturing defects in solder reflow. SEMIKRON PressFit modules are prone to stress-induced fractures in the semiconductor die attach solder.
- ✓Gate driver IC failure and signal loss — Power supply voltage transients, reverse polarity application, or electrostatic discharge (ESD) damage during handling. SEMIKRON integrated modules with on-board drivers are susceptible to cascading failures affecting multiple switching functions.
- ✓Thermal management failure and die attach degradation — Loss of heatsink contact due to corrosion, improper mounting torque, or thermal paste degradation over years of operation. Inadequate cooling leads to junction temperature runaway and accelerated electromigration in bonding wires.
- ✓Phase-leg short circuit and cross-conduction — Gate signal timing violation, gate drive asymmetry, or parasitic capacitance coupling in SemiX stacks. Improper grounding or shielding of control lines introduces cross-talk leading to simultaneous upper and lower IGBT conduction.
- ✓Case isolation breakdown and leakage current — Moisture ingress causing surface creepage and tracking on the module case, or mechanical damage exposing the semiconductor to humidity. SEMIKRON modules in coastal or high-humidity Indian environments (Tamil Nadu, Kerala) degrade faster.

Can you repair SEMIKRON SKiM modules with integrated gate drivers?+
Yes. SKiM module repair is a core competency at Synchronics. We perform gate driver IC replacement, IGBT die re-characterization, solder joint rework, and thermal interface restoration. We stock compatible SKiM components and can source genuine SEMIKRON parts from authorized distributors. All repairs include isolated gate voltage testing and full load-cycle validation.
What warranty do you provide on SEMIKRON power module repairs?+
We provide 12 months full replacement warranty on all SEMIKRON semiconductor repairs against defective workmanship, failed components, and design-related issues. Warranty covers material failure and functional testing under rated specifications. If a repaired module fails within warranty, we replace it free of charge including courier costs. Extended 24-month warranties are available for critical OEM applications.
Do you handle SEMIKRON drives and control boards, or only power modules?+

What is the cost of repairing a SEMIKRON drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on SEMIKRON repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your SEMIKRON unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
