History
• Societa’ Italiana Chemical Machining S.p.A. was founded in 1970 and was the first italian company to develop the process of Photo Chemical Milling • By always being in the forefront of this technology and by focusing on quality without compromises the Company has been able to keep the number one position in the local market and to be rated in the top ten independent Chemical Milling companies worldwide • In 1995 the Company expands his production lines to include a Laser Cut Department to enter the market segment of very high precision metal parts • In 2003, to further enhance its presence in the electronics market the Company acquires Seritronics Srl a market leader in SMT technologies • In 2004 the laser department is enhanced with a last generation laser cutting machine, in order to be able to produce extremely high precision stencils and mechanical parts • In the course of more than three decades the Company has been steadily growing both in terms of turnover and of headcount, even during economy downturns • After consolidating its position as undiscussed leader in the Italian environment Chemical Machining S.p.A. is now aggressively approaching the foreign markets by leveraging an excellent quality/price ratio achieved through continuous process improvement during decades of experience
Services
• Photo Chemical Milling is a high technology process which basically consists of controlled removal of metal particles by a chemical solution with a combined chemical and physical action. This process is particularly convenient in the case of high precision, complex geometry objects, and can be used for a wide range of metal and alloys, with a broad scale of thicknesses. The individual pieces are kept together through tie-ins or tabs and can be detached manually or by a cutting machine. The application of this technology spans over virtually every market and is cost effective from prototyping to medium and high volume production. Chemical Machining S.p.A. has developed several partnerships with suppliers of finishing techniques, bending, forming etc in order to be able to deliver completely finished parts to its Customers
• Laser Micro Cutting: with this technology extremely high precision parts can be achieved with tolerances down to 3 microns on thicknesses from 0,05 to 0,8mm. Apertures of thin as 10 micron can be easily achieved
• Surface Mount Technology: through the recently acquired Seritronics the Company is now able to offer advanced stencils, printing screens, and thick film technology with several patented innovations to address correct soldering of microcomponents such as 0201, CSP etc. An extensive customer support is included which starts from consultancy at pcb design level to in depth analysis of paste deposit and process yield.

PHOTO CHEMICAL MILLING
ON CUSTOMER DEMAND
Photo chemical machining vs traditional technologies: major benefits:
-very low tooling costs -highest flexibility: cost is not dependent on complexity -very high precision, tolerances as low as +/-0,015mm -wide range of thicknesses, from 0,02mm to 2mm -no effect on the molecular structure of the metal: components are burr free while temper and magnetic properties remain unchanged; no strains or stresses are generated by this process. -Very short delivery time in the order of days -Competitive costs both for prototyping and for medium/high productions
Techniques such as half-etched bend lines facilitate complex hand forming of parts, saving the cost of hard tooling. Integrated marking reduces handling and cost.. This feature is particularly useful to build EMI/RFI shielding
On Customer request Chemical Machining S.p.A. is able to supply a complete service which includes galvanic surface treatment, painting, Teflon coating, PVD etc. It is also possible to offer bending, forming and assembly of complete subsystems.

PHOTO CHEMICAL MILLING
The process
The production of Chemical Machining follows an optimized process well proven over 35 years of leadership in the Italian market. The Customer submits a design (in any form or shape, but a dwg or dxf file is preferred) together with all relevant information including which is the target market of the finished product. The Technical Office evaluates the feasibility i.e. the applicability of photochemical milling to the particular project and supplies all the cost information to the Sales Office which will prepare the offer to the Customer. When the Customer releases the order a photo tool will be generated by proper CAD software, and the negative of the shape of the part is impressed by light exposure on a thin photosensitive film which is attached to both sides of a metal sheet. The metal sheet which now contains the negative image of the part on both sides is then developed in a special machine, by which the film polymerizes in the zones that have not been exposed to light. Then the sheet is ready to enter into the etching machine where a special acid will etch the zones that are polymerized; a sheet may contain several replicated parts which remain attached to the sheet by means of small tie-ins or tabs. After that the remaining film is stripped away and the parts are ready to be delivered to the Customer. Chemical Machining can provide on demand a complete service by which includes all finishing processes like galvanic treatments, painting, tefloning, sieving, bending, forming etc
Lot of application areas
Photo Chemical milling is basically a 2D technology: all pieces are developed on a plane. This may become a limitation in the mind of a designer who does not see immediately how to develop a 3D object on a plane. This is the reason why a very close communication is necessary between the designer and our technical staff in order to exploit all the potential of this technology. To that end Chemical Machining regularly organizes technical workshops at its premises in order to allow its Customers to take full advantage of this technology. In fact, although the production is mainly on 2D objects, three-dimensional parts can be achieved as well and is possible on almost every material with the exception of noble metals like gold, titanium, molybdenum and a few others who have an extremely high resistance to the etching process. Photo chemical milling is well suited to several applications, that range from models to gobos, to precision mechanics, to stencils, to fashion accessories: the complete list would be too long and is limited only by the fantasy of the designer. Generally speaking this technology is particularly convenient on thicknesses are between 0,02 and 2 mm. when geometries are very complex, tolerances are very tight, and time to prototyping and production is short. It is also possible to achieve full and half etching on the same part, creating many different effects and functionalities. Last but not least it has to be remembered that the cost of tooling is order of magnitudes lower than competing technology and is largely independent on product complexity
Market segments
We briefly recall some of the market segments where photo chemical milling is employed more successfully:
Precision Mechanics - Electronics - Telecom - Automotive - Space and Military - Medical Equipment -Textile - Glasses - Lighting - Springs - Electric Engines - Instrumentation - Ornamental - Fashion accessories - Research Labs

LASER MICRO CUTTING
The process
Laser technology has quickly transitioned from research lab to industrial production. Several features of laser beam make this technology particularly attractive: among all extremely tight tolerances and excellent quality of cut edge like in the new LPKF model 800 we have recently acquired. The cut speed has also greatly improved so that we can now guarantee a fast and reliable delivery to our customers. The tolerance of this system is as tight as 3 micron on the whole working area of 800X800 mm. This system is also equipped with a camera for continuous control of parts being cut.
With our new Laser Department we can offer the following benefits:
Speed: 5 days typical turnaround time, down to 24 hours for urgencies Metals: Carbon steels, inox steels seriee aisi300, aisi400, 11R51, 7C27mo2, etc Thickness. Generally from 0,05mm to 0,8mm Precision: Tolerances of +/-3 micron can be achieved Minimum quantity: onepiece Requested doc: mechanical drawing or sample
Areas of application
The main target fields for Laser micro cut are: very high precision mechanics, stencils for SMT, research labs and Universities, where the requested precision is in the area of below one hundredth of millimetre and where apertures as little as 10 micron are required
