Services Nuova Eurotar

The company currently manufactures all types of products including the most advanced and technologically complex required to meet the needs of the sectors to which it is interested and involved.

Starting from the double sided until multilayer (flexible, rigid and rigid-flexible, the latter produced exclusively with a selective non-adhesive technique), Nuova Eurotar is able to use these for the more complex applications, such as:

• Use of special materials (ie. PTFE or ceramic based, in particular for RF specific applications)
• Mixed materials, meaning the simultaneous use of multiple types of materials within the same lay-up (hybrid PCBs)
• High technology Holes (press-fit techniques, blind, buried, m icro- holing)
• Hole plugging (both blind and PTH) using a technique with epoxy resin (also selective)
• Controlled impedance
• SBU technology and / or controlled depth drilling
• Heat sink application, both internai and external
• Internai processing metal-backed, on substrates equipped with all the main types of carrier (copper, brass, aluminum) with controlled depth routing techniques
• Application of selective fep-teflon
• Production of PCBs with fingers suspended, in partial or total absence of support (mainly reserved to the types flexible and rigid-flexible)

The main finishes will include:

• HAL
• Sn / Pb refused
• High thickness electrolytic pure gold (pre-etch)
• High thickness electrolytic nickel-gold (pre-etch)
• Electrolytic pure Sn
• ENIG
• High thickness electrolytic Ag post-etch
• Finishing mixed and / or selective

The production cycle relies, instead on some important technological solutions:

• The direct-melting technology on PTFE, namely the abilíty to run lay-up without using adhesives, by direct fusion of the substrate through the use of a Lauffer press customized at high temperature (410° C), equipped with a special dedicated diathermic oil. This solution allows the ability to obtain "clean" substrates made exclusively of pure Teflon and copper, with clear advantages on the solidity, on the guarantee of the conductors encapsulation and on the frequency response, because it is avoided during introduction of "pollutants" elements contained in the products normally used for bonding the PTFE substrates. This technique, long studied and experimented by Nuova Eurotar during recent years, is currently fully consolidated among the solutions offered by the company, and is already successfully applied in the production of many special products used in specific projects. This process ís also used in numerous applications in which the overall weight of the finished product is a crucial element, specifically, for example, in replacing metal screws. This solution, in fact, allows the abilíty of the significant reduction of the overall weight of the apparatus (decisive in products which must be used on vehicles in flight) and an improvement of adhesion and sealing of all the involved surfaces.
• The plasma treatment, which is systematically applied to all special products which require it. This treatment, whose advantages and benefits effect aspects of cleaning and activatíon are now universally recognized. It is also used in other applications (for example in the cleaning of the surfaces for the deposition of protective films and resins).
• The exclusive use of Conformask as a solder resist, which is a protective photographic dry-film capable to ensure a constant and defined thickness over the entire surface of the card treated, as well as the perfect encapsulation of all conductors.
• The specialized mechanical work (counter bore, threading, metallic milling etc..) on all materials, through the use of a modern automated mechanical station. The company recently acquired this mechanical station and has faced a long phase of experimentation necessary to adapt to the characteristics of the machine and tools designed to work other types of materials (pure metals) to materials necessary for the production of PCB (metals combined with ceramic substrates, PTFE etc..).
• The maximum optimization of the galvanic treatment lines, obtained by the most advanced and proven technical solutions, properly applied and used based on specific experiments carried out directly by engíneers within the company in collaboration with the R&D of the most qualified suppliers.

All of the types of products and technological solutions available, listed and used by Nuova Eurotar are only part of what the company is capable of realizing.

The constant ínterest of the firm to study new projects proposed by the most qualified customers involves an ongoing and continuous adaptation of the structure to the new requirements, in terms of facilities and infrastructure, but also in terms of training qualified employees and staff awareness.

A path of continued improvement is what our company will seek and pursue. Nuova Eurotar company wants to continue to experience success with the active cooperation of the most qualified clients, both current and future.
