ANSWERS FROM AN EXPERT WITH 85 YEARS’ EXPERIENCE IN THE ELECTRONICS SECTOR

Do you want to find out more about PRUFREX, the expert in control and regulator intelligence? Do you lack your own electronics manufacturing or are you looking for valuable practical tips?

Benefit from our experience as a system partner, offering you comprehensive development, production and logistics competence. With our smart solutions, we equip you for the future and industrialise your ideas. You can find the answers to your questions here.

DEVELOPMENT IN GENERAL

WHAT IS THE ADVANTAGE OF THE PRUFREX IN-HOUSE TEST EQUIPMENT DEVELOPMENT?

Our test equipment developers work closely together with production. In this way, a test concept for later manufacture can be drawn up in parallel with development and then implemented by the test equipment developers. This means each product can be abundantly tested.

WHAT ARE A/B/C MODELS?

The degree of maturity of a model grows over the development process. For each model phase, a review of the maturity achieved is carried out to guarantee product quality. The individual phases are:

A model: functional model of low maturity, e.g. using 3D-printed components.

B model: functional basic model of high maturity, can be manufactured using auxiliary tools.

C model: fully functional model manufactured using mass-production tools.

WHAT IS THE USUAL PROCESS FOR COMPLETE DEVELOPMENT?

We support our customer throughout the entire development process. From the initial idea onwards, we make sure the later product works without error and can be manufactured economically. We carry out studies, develop and produce the first prototypes and transfer these through A/B/C model phases to serial production.
 

During the entire development process, we constantly refer back to the project goals.

HARDWARE DEVELOPMENT

WHAT TOOLS ARE USED IN HARDWARE DEVELOPMENT?

For the circuit diagram and layout development we use Altium Designer 21, while circuit simulation is carried out with Spice.

QUALITY IN GENERAL

ARE YOU CERTIFIED? IN WHICH AREAS?

PRUFREX is certified according to the following standards

 

ISO 9001 - Quality Management

ISO 14001 - Environmental Management

 

DESIGN

WHAT TOOLS ARE USED IN CONSTRUCTION DEVELOPMENT?

We use SolidWorks 2020.

WHAT TASKS DOES YOUR CONSTRUCTION DEPARTMENT TAKE ON?

With our in-house product and tool construction, we support development from the initial concept through structural safeguarding to prototyping and mass production.
 

RAPID prototyping with our own 3D printers, CAD/CAE development and a broad range of further analysis, simulation and construction tools ensure we fulfil the technical and economic requirements.

ECONOMIC EFFICIENCY

ALLOCATION AND COMPONENT AVAILABILITY – HOW DO YOU SAFEGUARD PROJECTS AND PRODUCTION?

Here at PRUFREX we work using established processes in material management and order processing. This makes an essential contribution to the reliability of our comprehensive overview founded on unified underlying data. This is how we keep a good overview and are able to react in good time, avoiding bottlenecks.
 

To ensure the availability and approval of second-source components, the close networking of product development, test equipment development, testing, validation and production are a significant advantage. Already during product development, second-source components are considered. This means reaction to developing supply bottlenecks can be swift, allowing components to be switched in good time.
 

Thanks to our product expertise, we can quality-assess and approve further components, meaning that if supplies run short, delayed shipments can be avoided and significant amounts of time can be saved.
 

This is ensured through established approval processes (change management) within the company, meaning that every approval is documented and traceable.
 

Our expert purchasing team also keeps up intensive contact with a large number of suppliers and manufacturers, helping them stay informed of the latest developments on the market and take any necessary measures in good time.

WHERE ARE BAD INVESTMENTS MOST FREQUENTLY MADE DURING PRODUCT DEVELOPMENT?

The later errors arise in the development process, the more difficult they are to eliminate, and the more expensive. Through the close networking of hardware and software development, construction, testing and validation, test equipment development and manufacture, one can ensure from the very start of a project that the product can be efficiently manufactured. Quality gates during product development ensure that a review takes place after every development phase and product quality is assured.

PRODUCT QUALITY

WHAT IS THE DIFFERENCE BETWEEN POTTING IN A VACUUM AND A PROTECTIVE ATMOSPHERE?

Air bubbles in the potting or product can cause significant problems. For example, ignition coils need to be completely saturated. Because of the high voltage, no bubbles may exist here. This requires high-specification plant technology that PRUFREX has in various forms.
 

Not each product needs to be potted without bubbles. There are parts that are unsuitable for vacuum potting. PRUFREX is also equipped for such requirements and has extensive knowledge of this potting technology.

RAPID PROTOTYPING – HOW DO YOU ENSURE EFFECTIVE PRODUCT DEVELOPMENT IN ITS EARLY STAGES?

With our own 3D printers, CAD/CAE development and a wide range of analysis, simulation and construction tools, PRUFREX ensures fulfilment of all technical and economic requirements.

POTTING TECHNOLOGY – HOW DO YOU PROTECT YOUR PRODUCT FROM EXTERNAL INFLUENCES?

PRUFREX is a leader in the field of vacuum potting. If secure protection for your electrical and electronic components is what you want, our ultra-modern, automated production lines can fulfil any contemporary demand.
 

For mechanical protection, reliable electrical insulation, humidity repulsion and heat dissipation, we use optimised casting resins (polyurethane, epoxy etc.) that are adapted to your customer-specific requirements.
 

Depending on the product type and environmental conditions, we use vacuum potting or potting in a protective atmosphere.

MATERIAL COMPLIANCE – HOW DO YOU HANDLE MATERIAL AND PRODUCT REGULATIONS?

We ensure material compliance using an environmental management system as per ISO 14001 - Environmental management system . In addition, our QA department carries out regular checks and tests.

DO YOU HAVE AN AUDITABLE MANUFACTURING PROCESS?

Our networked production based on the MES (Manufacturing Execution System) ensures the secure control of our complex production lines and the effective functioning of each production process in interplay with the others. At PRUFREX, every part or component is uniquely identifiable using its serial number.

TRACEABILITY – WHAT BATCH OF COMPONENTS HAS BEEN INSTALLED IN WHICH PRODUCT?

Using its modern plants and established MES (Manufacturing Execution System), PRUFREX is able to record material, test and shipment data for each unique item.
