Process Verification

Maintaining a stable and reliable soldering process is essential for producing high‑quality electronic assemblies, but even well‑configured equipment can drift over time. Process verification ensures your reflow, wave, or selective soldering systems continue to perform exactly as intended, helping you catch issues early, reduce defects, and keep production running smoothly.

The Challenges of Reflow Process Verification

Process verification can be difficult as soldering equipment naturally drifts over time as heaters age, airflow changes and conveyor systems slow down, all of which can affect temperature stability and solder quality.

Many manufacturers still rely on test PCBs for verification, but these boards degrade with repeated heat exposure, making their measurements less reliable and increasing replacement costs.

Manual checks add further challenges, as they take time to set up and can miss subtle variations that impact performance. Small process changes often go unnoticed without a stable reference point, meaning issues may only be discovered once defects appear on the line.

Even when data is collected, it can be hard to interpret without the right software tools, making it difficult for operators to maintain consistent process control and long‑term reliability.

How Solderstar can help

Solderstar’s Process Verification Approach

SolderStar transforms process verification from a time‑consuming challenge into a fast, reliable, and repeatable part of your production workflow.

A stable, repeatable reference tool

SolderStar uses fixed‑sensor shuttles, such as the DeltaPRObe to create a “golden profile” — a reliable baseline that doesn’t degrade over time.

Fast, repeatable oven checks

Instead of profiling with a PCB every time, operators can simply pass the DeltaPRObe through the oven to verify performance in minutes.

Automatic detection of process drift

The system compares each run to the golden profile and instantly flags changes in convection, temperature, or conveyor speed.

Integrated SPC and analysis software

SolderStar’s software provides tolerance bands, trend charts, and process‑control tools that make verification simple and visual.

Support for multiple soldering processes

Reflow, Wave, Selective, and Vapour Phase processes can all be monitored using SolderStar’s modular accessories and software.

Benefits of SolderStar Process Verification & Software

With SolderStar’s intelligent tools and software working together, manufacturers gain a faster, clearer, and more reliable way to keep their soldering processes performing at their best.

Consistent solder quality

By catching drift early, manufacturers maintain stable, repeatable solder joints across all production runs.

Reduced scrap and rework

Issues are identified before they affect product quality, saving time and material costs.

Faster, easier verification routines

Operators can complete oven checks quickly without setting up thermocouples or risking damage to test boards.

Clear, visual process insights

Tolerance bands, SPC charts, and automated alerts make it easy to understand what’s happening inside the oven.

Long‑term traceability

All verification runs are logged, helping manufacturers meet quality standards and customer audit requirements.

Frequently asked questions

Test PCBs degrade with heat and repeated use, which makes their measurements less reliable. They also require thermocouples and setup time. A fixed‑sensor tool like the DeltaProbe stays consistent and is much faster to use.
