What is QUINS Pro?

QUINS Pro is an optical inspection system for printed circuit boards and electronic assemblies. It supports visual inspection, reference-image inspection, component placement checks, solder joint inspection and golden-board comparison. Typical application areas include incoming goods inspection, first article inspection, sample inspection, series inspection and final inspection in electronics manufacturing.
QUINS Pro is an optical inspection system for checking printed circuit boards and electronic assemblies. It is used to reliably detect, compare and document visually visible defects in components, solder joints, PCBs, paste application and protective coating.
The system is suitable for manual and assisted inspection processes in electronics manufacturing — from incoming goods inspection through component placement checks to final inspection. By comparing with a reference image or golden board, QUINS Pro helps users quickly identify deviations and securely preserve inspection results.
QUINS Pro is particularly suitable for companies that want to standardise visual inspection, relieve staff and build complete inspection documentation.

Proven in Practice

QUINS inspection systems are in use at over 750 customers. Depending on the inspection task, a new reference assembly can be captured and prepared for comparison within a few seconds.

Optical inspection for every step of your electronics production

QUINS Pro can be flexibly integrated into various inspection processes. The system supports quality control, production and development wherever printed circuit boards, electronic assemblies or optically inspectable components must be assessed reliably. Typical application areas are:
  • Incoming goods inspection of PCBs and assemblies
  • Paste inspection before or during production
  • Component placement checks for SMT and THT components
  • First article inspection and release of new assemblies
  • Sample inspection in ongoing production processes
  • Component inspection and position control
  • Reference-image inspection with comparison to a reference image
  • Golden-board comparison for detecting deviations
  • Manual solder joint inspection
  • THT inspection and SMT inspection
  • Set-up control and production release
  • Outgoing goods inspection and final inspection
  • Series inspection for small, medium and large series
  • UV inspection of protective coatings and conformal coating with QUINS Pro UV
Whether prototype, small series or series production: QUINS Pro helps make inspection processes faster, safer and better documented.
Error detection

Recognise, compare and document visible defects

QUINS Pro supports the detection of all visually visible defects on printed circuit boards, assemblies, components, solder joints, paste application and protective coatings. As a result, the system is suitable both for conventional visual inspection and for structured inspection processes using a reference image, golden board or reference-image inspection.

Typical component defects

  • Component missing
  • Component incorrect
  • Component twisted
  • Component reversed
  • Component shifted
  • Component standing upright
  • Component defective
  • Component over-populated
  • Pin bent
  • Incorrect component position
  • Incorrect PCB version

Typical solder joint defects

  • Solder bridge
  • Solder joint not soldered
  • Defective solder joint
  • Solder bead on joint
  • Contaminated solder joint
  • Manually noticeable solder connection
  • Visible interruptions or missing areas

Typical paste and coating defects

  • No paste
  • Too little paste
  • Too much paste
  • Smudged paste
  • Paste bridge
  • Missing protective coating
  • Too little coating
  • Too much coating
  • Coating splashes
  • Bubble formation
  • Errors in the conformal coating layer with UV variant

Typical PCB and structure defects

  • Damage
  • Contamination
  • Trace interruption
  • Trace too narrow
  • Trace too thick
  • Incorrect bridge
  • Incorrect hole
  • Hole too large
  • Hole too small
  • Too little solder resist
  • Too much solder resist
QUINS Pro does not replace a professional assessment by trained personnel, but it does make visual inspections substantially more structured, reproducible and better documented.
Advantages

Why QUINS Pro?

Ready for use quickly

QUINS Pro has been developed for practical use in production and quality assurance. The setup is simple, the entry is intuitive and the inspection process can be used productively within a short time.

No programming effort

The system is designed to set up inspection processes without classical programming effort. That means changing products, prototypes and small series can be inspected efficiently.

Ideal for golden-board comparison and reference-image inspection

With QUINS Pro, test items can be compared with reference images or a golden board. Deviations become visible more quickly and can be assessed and documented transparently.

Complete documentation and traceability

Inspection results can be documented automatically. This supports traceability, quality assurance and internal evidence requirements — in a tamper-proof and process-oriented way.

Relief for staff

QUINS Pro supports inspectors directly in their daily work. The clear image display, simple operation and structured inspection provide less searching, less uncertainty and tangible relief from day one.

Flexible for different production steps

Whether incoming goods, component placement checks, solder joint inspection, final inspection or series inspection: QUINS Pro can be used at various points in the production process.

Durable, practical hardware

The hardware is robust, ESD-safe and designed for long-term use in production-like environments. QUINS develops hardware and software in a practical way — with direct feedback from real customer applications.

Over 30 years of experience

QUINS has stood for optical inspection systems from Germany for over 30 years. This experience flows into the operating concept, hardware, software and support.
Inspection workflow

How optical inspection works with QUINS Pro

1. Capture a reference

A reference image, a golden board or a defined inspection state is first created. This serves as the basis for the later comparison.

2. Place the test item

The PCB or assembly to be inspected is placed in the system. Depending on the application, SMT, THT or mixed assemblies can be inspected.

3. Capture an image

QUINS Pro captures the assembly in high resolution and with shadow-free illumination. The specially developed LED lighting supports a clear representation of components, solder joints, markings and surfaces.

4. Detect deviations

Compared with the reference image, visible differences become much easier to see. This helps with missing, incorrect, shifted, twisted or reversed components as well as visible solder, paste or coating defects.

5. Document the result

Irregularities and inspection results can be documented in a traceable way. This creates a transparent inspection history for quality assurance, traceability and internal release processes.
Variants

QUINS Pro variants for different inspection tasks

Not every inspection task places the same demands on resolution, lighting, assembly size or component height. That is why QUINS Pro is available in several variants.

QUINS Pro

The proven optical inspection system for PCBs, electronic assemblies, incoming goods inspection, component placement checks, solder joint inspection, golden-board comparison and final inspection.

QUINS Pro UV

The UV variant is suitable for inspection tasks around protective coatings and conformal coating. It makes missing coating, too little coating, too much coating, coating splashes or visible coating distributions visible and documentable.

QUINS Pro HR

QUINS Pro HR is the high-resolution variant for particularly detailed inspection tasks. With a resolution of up to 4,800 dpi, the HR variant is suitable for applications where the smallest details must be safely visible. More on this: QUINS Pro HR.

QUINS Pro Tableau / PCB

Suitable variants are available for test tables, PCBs or larger PCB formats. These are particularly suitable for inspection processes where several PCBs or larger formats are compared and documented efficiently.

QUINS Pro Longboard, Highboard and Bigbox

Special variants such as Longboard, Highboard and Bigbox are available for oversized boards, particularly tall components or special test applications. This allows QUINS Pro to be adapted to special requirements in production and quality assurance.
