Wave Soldering -

Precision Wave Soldering Services
for High-Reliability Electronics

At OnicsTech, we understand that the heart of any reliable electronic device is a perfectly soldered printed circuit board (PCB). As a dedicated OEM electronics manufacturer, we prioritize precision and consistency at every stage of production.

Whether you are scaling up for high-volume manufacturing or require rigorous quality controls for mission-critical electronics, our soldering infrastructure is engineered to deliver flawless, long-lasting mechanical and electrical connections. We combine state-of-the-art equipment with strict quality assurance to ensure that every PCB assembly meeting our floor exceeds industry standards.

Our Wave Soldering Process

Wave soldering is a cornerstone of efficient, high-yield through-hole and mixed-technology PCB assembly. Our facility utilizes a highly controlled, automated wave soldering process designed to minimize defects and maximize throughput.

Flux Application

We apply a precise, uniform layer of high-grade flux to the bottom of the PCB. This removes surface oxides and prepares the copper pads and component leads for optimal solder wetting.

Controlled Preheating

The board passes through a series of thermal zones. This gradual preheating prevents thermal shock to sensitive electronic components and activates the flux, ensuring a clean, receptive surface.

The Solder Wave

The PCB is passed over a continuous, dynamic “wave” of molten solder. Our precisely calibrated wave dynamics ensure that solder wicks perfectly up through the plated through-holes, creating strong, void-free fillets.

Gradual Cooling

Finally, the assembly is cooled at a controlled rate. This solidifies the solder joints securely while preventing mechanical stress on the board and components.

Wave Soldering – Process Features

Our wave soldering line is equipped with advanced features to guarantee the highest level of manufacturing excellence for your products:

Exceptional Joint Reliability

Automated temperature profiling and wave dynamics eliminate the inconsistencies of manual soldering, resulting in highly reliable, uniform solder joints.

High-Volume Efficiency

Designed for scale, our process significantly reduces cycle times, allowing for rapid, cost-effective production runs without sacrificing quality.

Lead-Free & RoHS Compliant

We maintain strict adherence to environmental and industry standards, utilizing premium lead-free solder alloys that ensure global compliance and safety.

Advanced Thermal Profiling

Every batch is guided by custom thermal profiles specific to the board’s density and component mix, completely preventing thermal damage or incomplete wetting.

Rigorous Post-Wave Inspection

Every assembly undergoes thorough automated optical inspection (AOI) and visual checks to verify solder bridge absence, complete hole fill, and overall joint integrity.
