HELLER Product Lines We Repair
Our engineers are trained on the full HELLER product range. Below are the major product families we service.
Heller Wave Soldering Machines
Wave soldering systems for through-hole component assembly with integrated process monitoring and flux management. Common issues include solder pot temperature regulation failure, conveyor motor drive faults, and control board PCB degradation from thermal cycling.
Heller Reflow Ovens
Convection reflow ovens for surface mount technology (SMT) assembly with programmable thermal profiles. Typical failures include heating element burnout, blower motor degradation, thermocouple sensor drift, and control module firmware corruption.
Heller Selective Soldering Systems
Targeted selective soldering machines for mixed-technology boards combining wave and selective processes. Repair issues center on valve controller failures, solder temperature sensor malfunction, and nozzle positioning servo faults.
Heller Thermal Profilers
Real-time thermal measurement and process profiling equipment for reflow and wave soldering validation. Common problems include thermocouple breakage, data logging memory failure, and communication interface corruption.
Heller Control Modules and PLC Systems
Industrial controllers and programmable logic boards for soldering equipment automation and process monitoring. Failures include capacitor degradation, relay module burnout, and communication bus (CANopen, Ethernet) interface breakdown.

Common HELLER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HELLER equipment arriving at our workshop.
- ✓Reflow oven heating element open circuit — Thermal cycling stress and oxidation of nichrome heating elements in Heller 1700/1800 series ovens. Repeated heating to 250°C+ causes element brittleness and eventual fracture, breaking the heating circuit.
- ✓Wave solder pot temperature runaway or loss of heat — Thermocouple sensor degradation or control board relay failure in Heller wave soldering machines. Solder oxidation and flux residue corrode sensor elements, giving false readings that cause uncontrolled heating or shutdown.
- ✓Conveyor motor stall or intermittent motion — Worn brushes and bearings in DC or AC conveyor motors, combined with accumulation of flux and solder spatter around motor shaft and gearbox. Heller machines run 8-12 hours daily, accelerating wear.
- ✓Control board capacitor leakage and power supply instability — Electrolytic capacitors in Heller control modules age and dry out in high-temperature equipment environments. Leakage currents reduce voltage regulation, causing intermittent faults, display glitches, and sporadic machine stops.
- ✓Blower motor noise and reduced airflow in reflow oven — Ball bearing wear and blade erosion in centrifugal blowers used for convection in Heller reflow ovens. Solder vapor and flux aerosols accelerate bearing degradation and blade corrosion, reducing cooling efficiency.
- ✓Thermocouple open circuit in selective soldering nozzle — Vibration during solder dipping and thermal stress crack or corrode thermocouples in Heller selective soldering equipment. Broken wires break the temperature feedback loop, blocking solder flow and forcing machine shutdowns.

Frequently Asked Questions — HELLER Repairs
Do you repair Heller soldering equipment anywhere in India?+
Yes. Synchronics repairs the full Heller product range — wave soldering machines, reflow ovens, selective soldering systems, thermal profilers, and control modules. We offer PAN India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all tier-1 and tier-2 cities. All repairs are processed at our 12,000 sq ft facility in Vadodara, Gujarat, with 180+ trained engineers.
What is the typical turnaround time for Heller reflow oven repair?+
Standard turnaround is 3-5 working days for reflow oven repairs, including thermocouple replacement, heating element refurbishment, and blower motor service. Critical failures like heating element open circuit can sometimes be resolved in 24-48 hours if spare parts are in stock. We prioritize urgent cases for electronics manufacturers facing line downtime. Timeline is confirmed when repair is logged.
Can Synchronics repair Heller wave soldering machine solder pot temperature sensors?+
Yes. Heller wave machines rely on accurate solder pot thermocouples (typically K-type) for precise temperature control at 245-255°C. Synchronics replaces corroded or open-circuit thermocouples, cleans flux deposits from sensor wells, and recalibrates the temperature control loop using calibrated reference probes. We test thermal stability over 2+ hours before return to ensure reliable solder joint quality.
What spare parts does Synchronics stock for Heller equipment repairs?+
Synchronics maintains stock of high-wear Heller components including heating elements, thermocouples, blower motors, conveyor drive belts, and electrolytic capacitors for control boards. For rare or NOS (new old stock) parts, we source directly from Heller Germany or authorized Indian distributors, typically within 2-3 weeks. Emergency parts can be expedited for critical manufacturing lines.
Do you offer preventive maintenance and thermal profiling validation for Heller soldering lines?+
Yes. Beyond repair, Synchronics provides preventive maintenance contracts and thermal process validation for Heller reflow and wave soldering equipment. We conduct CPK (process capability) studies, profile PCB thermal curves, and issue compliance reports meeting IPC-A-610 and J-STD-020 standards. Regular PM extends equipment life and reduces unplanned downtime for Indian electronics manufacturers.
How do I send my HELLER unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HELLER 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 HELLER 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 HELLER 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.
