What Assel does

Assel sp. z o.o. is a privately held Polish contract electronics manufacturing services (EMS) provider headquartered in Pruszcz Gdański, tracing its operational lineage to Proelco/JP Electronics founded in 1982 and operating under the Assel brand since 1999. The company specializes in high-mix, high-complexity electronics assembly and electro-mechanical systems integration, serving enterprise customers across Industrial, MedTech, Energy & Cleantech, Transportation, and Connectivity verticals, with a recently added Security Systems vertical enabled by NF A2P certification. Core manufacturing services include SMT and THT PCB assembly, box build, cable harness assembly, and electro-mechanical assembly, supported by value-added offerings in conformal coating and potting, supply chain management, test engineering, new product introduction, and after-sales product care.

Operations run from a single 7,000 m² manufacturing complex built in 2007, equipped with modern SMT lines (DEK TQ printer), selective soldering (Vitronics Soltec ZEVAm+), and X-RAY inspection (Quadra-3), operated under ISO 9001, ISO 14001, ISO 13485, ISO 22301, and IPC-A-610 (class 2 & 3) management systems. The technology stack is conventional industrial EMS with a proprietary TTC traceability system and Microsoft Dynamics AX ERP; no proprietary AI/ML or software products are present. Assel's go-to-market is enterprise B2B field sales led by Business Development Managers (Marcin Popek, Przemysław Prolejko), supported by participation in major European electronics trade fairs (Electronica, Subcon, Southern Manufacturing, Elektronikmässan, Alihankinta, Electronics of Tomorrow) and a content marketing program.
