Selective Flux Sensors

The Wave Selective Flux Sensor expands the Solderstar Mini‑Wave selective measurement pallet to include flux detection capability. Designed to identify mis‑sprays, nozzle clogs, and X/Y positioning errors, it ensures flux is applied precisely where it’s needed — improving soldering quality and long‑term reliability across selective soldering processes.

Selective Flux Sensors

A simple, reliable way to confirm accurate flux application

Clear, reliable verification of selective flux application The WaveSelective Flux Sensor uses a four‑point detection system to confirm that flux is deposited accurately, consistently and in the correct location.

Integrated Sensor Array

Four precision sensor heads are mounted to the base of the Mini-Wave pallet, each programmed to receive a small flux deposit. The system measures surface resistance changes to confirm flux presence and position.

High-Resolution Detection Zone

With a 1 mm gap between sensor points, the array detects flux spots as small as 2–3 mm — providing a clear indication of spray accuracy and perpendicular jetting performance.

Signal Conditioning Circuit

A dedicated conditioning circuit enables sensitive resistance measurement, allowing reliable detection even with minimal flux deposits or varying chemistries.

Software Integration & Process Checker

When fitted, the Process Central software adds a Flux Sensor Checker chart, giving a red/green visual confirmation of which sensors detected flux during the diagnostic run.

Features

A compact, integrated system designed to detect mis‑sprays, nozzle clogs and positioning errors before they impact solder quality.

Detects flux presence and position directly on the Mini‑Wave pallet.

Comprehensive flux verification for selective process control

The WaveSelective Flux Sensor option gives manufacturers a dependable way to validate flux deposition as part of daily machine checks. By combining flux detection with contact, nozzle height, and temperature profiling, it provides a complete picture of the selective soldering process — helping engineers maintain consistent quality and prevent costly rework.

Adaptable software for different flux types

Different flux chemistries behave differently on sensor surfaces. The system’s programmable thresholds allow easy adjustment of detection sensitivity, ensuring accurate measurement across a wide range of flux formulations. This flexibility makes the WaveSelective Flux Sensor a future‑proof addition to any selective soldering setup.
