PCBA solutions
Your trusted partner for demanding PCB Assembly services
With 45 years of experience in electronics assembly, Assel is a trusted partner in Printed Circuit Board Assembly (PCBA) in Europe for Customers who require high level of reliability supported by proactive customer service. Our predominant emphasis is on high-mix, medium & low volume series, with a focus on demanding applications that require comprehensive range of assembly capabilities, as well as inspection and testing processes backed by strong engineering support.
Efficiency and Quality
With the use of latest technology, state-of-art SMT equipment and a flexible line set up suitable for both high mix, as well as serial production, we are able to place 600,000 cph (components per hours). Each SMT line is equipped with both a 3D SPI & 3D AOI inspection, ensuring that 100% of all PCBA’s are inspected. Our most advanced lines additionally include pre-reflow AOI, ensuring even tighter control specifically for high-tech and mission-critical applications.
Product & Process Traceability
With a deployed manufacturing execution system (MES) and automated labelling that supports unique serial numbering, we ensure 100% product traceability, supported by full traceability of the manufacturing process, including test and inspection data. On demand, we provide component traceability down to component batch or even single component if applicable.
In-House PCBA Tooling & Process Improvement
We internally design and build various PCBA assembly tooling, including soldering pallets/carriers (with titanium inserts), as well as various poka-yoke fixtures. This allows continuous improvement of our processes, enhances the quality and repeatability of electronics assembly in all areas.
