Continuous investment in technological innovation has made our production lines a real point of reference for all productions oriented to an error-free result.  The continuous review of production processes, aimed at constant improvement, allows us to rely on a structured organisation today, capable of preparing orders managed in “work account” and “full account”. All work environments are air-conditioned at a controlled temperature and adapted to the current ESD regulation concerning protection against electrostatic discharges. The staff is constantly trained: in accordance with IPC-A-610 and J-STD-001 standards.


SMT department

Today, ASS.EL. boasts an SMT DEPARTMENT (Surface Mount Technology) composed of two complete lines equipped with cutting-edge and latest-generation pick & place machinery capable of processing more than 10,000 components/hour with housing up to 0201. Continuous improvement of the machines and a high level of process control mean ASS.EL. is able to work with the minutest and the most voluminous technology without the quality standard being altered.

The fact that we have our own design centre and work with external centres allows us to experiment with technology advances, thus testing our machinery on the most diverse components. Ten-years of experience of the staff in the military aerospace and the civil field, and continuous training in compliance with the international standards for the processing of electronics (IPC-610) make ASS.EL. an ideal partner especially in areas where proactive collaboration takes on a fundamental value for achieving the result. In addition, ASS.EL. supplies tape & reel service for SMD components (as well for PTH components) for production automation.

THT Department

The THT DEPARTMENT (Through Hole Technology) is composed of IPC qualified operators, whose standards are fundamental in every step of the electronic product development cycle. The assembly service is applied both to lead-free and tin lead technologies, and also uses automatic wave soldering machines. Preforming the components and inserting them on the boards are performed manually, as are the repair welds on ESD benches. The completed boards undergo a further visual inspection by microscope or automatic optical control.


Conformal Coating

The CONFORMAL COATING technique involves dispensing a transparent “plastic” protective film (usually made of synthetic or acrylic resins) that adheres perfectly to the assembled board.

ASS.EL. can boast of possessing equipment for the silicone and acrylic resin coating of PCBs for military production. The conformal coating considerably improves the surface resistivity of the materials, such as printed circuits (PCBa), electronic components, etc., which must be used in very humid environments and could not withstand high temperature treatment.



The checking of the components on the PCBs is entrusted to high-resolution X-ray machines, which make it possible to check that welds have been correctly executed, thus avoiding problems such as shorts or voids that would make the operation of the electronic board unreliable. The visual inspection is entrusted to a machine called AOI (Automatic Optical Inspection), which detects assembly errors in real time, through a 3D reconstruction of the board and all its components, and signals them for repair. The company has also recently invested in an advanced electronic testing machine, called Flying Probe SPEA with mobile probe technology, capable of accurately and quickly testing every part of a circuit board, along with a Boundary Scan system that expands our Testing Department, allowing us to add a “pseudo-functional” test to the incircuit test (SPEA4060S2) and to the “functional” tests using TB. In fact, in addition to the functional checking of the components that integrate the aforementioned technology, the Boundary Scan test also makes it possible to test the interconnections of the components connected to them.



Our deep knowledge of the sector associated with special attention to new technologies gives us a presence on the market and means we can support the customer in the design phase and in the phase to identify the wiring; we cover the various activities from the supply of goods to electro-mechanical processing:


Assembly of drawers and rack cabinets


Electro-mechanical repairs
