PCBA-Assembly

The manufacturing of high-quality electronic cards requires complete mastery of all technological steps and strict quality assurance in accordance with IPC-A-610 standards. Particularly important are advanced competencies in testing procedures such as AOI (Automated Optical Inspection), ICT (In-Circuit Test), functional testing, and burn-in tests, which enable the delivery of daily results that meet 100% of customer expectations. At CLOOS electronic, we have integrated all the necessary competencies to consistently ensure this high standard.

Process

We process your order using your own Gerber files and parts lists. We supply all the necessary hardware, components and boards in accordance with our suppliers' manufacturing standards. We then optimise the panel configuration to reduce costs and guarantee excellent results. We comply with international standard IPC-A-610, but we can also adapt to meet other requirements, where necessary, to offer you the optimal solution.

Assembly of electronic boards

To meet the current demands of the electronics market, CLOOS has invested heavily in new high-tech installations to expand its production capabilities (assembly of standard and SMD components down to 01005, micro-BGAs, assembly on all substrates, FR4, ceramic, flex, aluminium, for PCBs from 1.5 m to the infinitely small). Our SMD machine park is efficient, modern, and at the cutting edge of technology to meet all aspects of electronic board assembly. THT assembly is fast, accurate and repeatable thanks to a process that uses a computer-assisted table of coordinates. Our selective machine enables us to meet the most exacting technical requirements, including PCBs with components on both sides.

AOI Testing and programming

Qualitätssicherung – egal ob für Leiterplatten aus der THT-Fertigung oder SMD-Bestückung – beginnt immer mit der AOI (automatische optische Inspektion) und endet mit dem In-Circuit-Test oder einem Funktionstest. To guarantee high-quality products, CLOOS electronic develops and produces testers to meet specific customer requirements, including in-circuit testing, boundary scan, data recovery, data matrix traceability and creation of test reports.

These packaging solutions provide optimal protection against electrostatic discharge and are ideal for international delivery, ensuring the integrity of electronics during logistics.

Sourcing and logistics

With a computer-aided logistics system, we manage all our processes absolutely reliably and can thus guarantee an exceptionally high level of service. With our experience in global procurement and purchasing non-electronic components for PCBA, we achieve optimal conditions through a high purchasing volume in the double-digit millions. This ensures you have access to high-quality components at competitive prices. Our extensive inventory includes over 17,000 different components, all cataloged with barcodes for quick and secure identification. Faced with challenges such as long delivery times or the discontinuation of specific components, we proactively offer suitable replacement parts to prevent production interruptions.

Box Building - Device Assembly

PCBA protection

To protect PCBA (Printed Circuit Board Assembly) from environmental influences such as humidity, dust, and mechanical damage, various methods are used, including the application of protective varnishes, encapsulation, or the use of enclosures. Additionally, directed plastic or parylene layers, as well as ceramic coatings, provide further reliable protection, ensuring the longevity and reliability of the electronic assemblies in various operating conditions.

Coating protection

The protective coating for Printed Circuit Board Assembly (PCBA) is an essential process to protect electronic components from environmental influences such as moisture, dust, and chemical substances, and we offer automated selective coating with an automotive-certified protective lacquer. This method not only increases the reliability and lifespan of the electronics but also ensures compliance with high standards, particularly in harsh operating environments or for applications subjected to high stress.

Potting

Potting, as a complete protection for systems, provides absolute sealing and high mechanical strength, even in the presence of vibrations. We offer this method, especially for assemblies exposed to high loads, to ensure their reliability and durability.

This image impressively illustrates how the coating protects the electronic components from moisture, ensuring reliability and durability in demanding environments.

Parylene conformal coating

Parylene is the thinnest and highest-performing coating available worldwide. Characteristics of Parylene conformal coatings include water resistance, resistance to corrosive materials, vibration reduction, low-stress application, complete conformity, high flexibility, low water permeability, high dielectric strength, enhanced mechanical stability for PCBs, electrical insulation resistance up to 15 kV for a thickness of less than 15 micrometers, and its absolute non-reactive characteristics, making it suitable for use as a medical-grade bio barrier. This allows for the production of direct implantable electronic boards without additional casings.

Glueing for Assemblies and Casings

Gluing is an essential bonding process in IP-compliant enclosure assembly and in the assembly of components, as it allows for a durable and robust connection while preserving the integrity of the protection classes. Plasma treatment of the surfaces to be glued is a crucial step to achieve maximum adhesion and optimize the bonding of the adhesive, which is essential for the long-term stability and reliability of the connection.

This image shows an automatic glue dispenser applying adhesive to a precision mechanism, illustrating advanced automation technology in mechanical assembly at Cloos Electronic. This process enhances precision and efficiency in manufacturing.

Manual Gluing

We have installed a complete ventilation system to safely and risk-free use all common two-component adhesives. Manual gluing is especially used in the assembly of complex components or in the gluing of enclosures in pre-series production, where the great advantage lies in the flexibility, thus allowing product modifications to be implemented without delay.

Automatic Gluing

We offer automated gluing for enclosure assembly, which is particularly effective on 4-axis robots for series production and on 6-axis robots for complex parts, while incurring minimal costs for tool creation. This process reliably meets requirements up to a protection class of IP 67, and it is also important to highlight the high shock resistance that results from the use of the correct adhesives.

Micro-precision systems

Based in the heart of the Swiss watchmaking industry, CLOOS electronic works closely with a network of partners specialized in the manufacture of high-precision micromechanical components. These high-precision components, combined with advanced electronics, are assembled by us into fully tested micro-precision systems (MPS) and then delivered to our customers.

This allows us to quickly and smoothly acquire materials such as aluminum die casting, MIM (Metal Injection Molding), laser cutting, as well as turned, milled, and chemically manufactured parts, including all necessary surface treatments.

Batteries small and big capacities

In the modern electronics industry, a reliable supply chain for batteries is essential, as batteries are a key component in a wide variety of products, from portable devices to electric vehicles. To ensure the safety, performance, and longevity of these batteries, comprehensive testing and measurement stations are necessary, allowing for continuous quality checks and performance tests.

Battery sourcing

In the procurement of batteries, used in applications ranging from IoT devices to energy storage systems, we cover a wide range of small units from 1 Wh to significant capacities of 10 kWh, and import directly from verified and reliable suppliers. Thanks to our established and approved supply chain, we guarantee adherence to high quality standards and efficient delivery, to meet the diverse and demanding needs of our clients in these areas.

Battery testing

To test batteries in terms of their capacity and cycle capability, we have specialized measuring devices. Particularly for batteries in the kWh range, power supplies and electronic loads with grid feedback are necessary, and we have these devices for performances up to 15 kW; for temperature qualifications, we use a climate chamber that covers a temperature range from -40 to 120 degrees.

Racks 19'' for IT and Systems

To meet all the requirements of modern 19-inch racks, we have our own 19-inch racks manufactured, from 10 U to 42 U, at extremely competitive costs.
