Suron's photo-etching technique processing a wide array of metal and alloys for your needs. This technique avoids burrs, no mechanical stresses are built into the parts and the properties of the metal worked are not affected. Hardened and tempered metals are machined as easily as regular metals. The technique is ideal for machining thin metals and foils. Parts with very precise and intricate designs can be produced without difficulty.
Technical specifications for the photochemical machining technology
All tolerances are directly expressed in relation to the metal thickness (T).
Minimum hole or slot width (W) is a function of the metal thickness (T).
Corner radii: photoetching generally results in rounded-off corners.
Suron offers both electroless nickel plating and nickel electroplating as a final plating layer or as an underplate for gold electroplating.
About the electroless plating technology:
Electroless plating is the technology of depositing metals from solutions without the use of an external source of electric current. In this process, electrons required for the reduction of metal ions are provided internally by reducing agents in an autocatalytic chemical reaction. The electroless bath provides a uniform deposit, regardless of size or complexity of the plated part. A sharp edge receives the same thickness of deposit, as does a blind hole.
Electroless plating also enables the metalizing of non-conductors.
Electroless Nickel
The most widely used engineering form of electroless plating is by far, electroless nickel.
Suron offers High Phosphorous Electroless Nickel according to AMS2404B (MIL-ST-26074E):
About the electroplating technology:
Electroplating is the technology of depositing metals from solutions onto metallic surfaces by cathodic discharge of metal ions. This process enables to build a thick plating layer relatively fast. The uniformity of the deposit is inferior to that of the electroless plating, due to disparity of current density along the plated part.
Nickel Electroplating
Sulfamate nickel is the most widely used electrolytic nickel. Sulfamate nickel is a pure and flexible deposit that allows soldering and brazing during later assembly steps. It is normally a dull silver color. Addition of brighteners causes internal stresses and lower ductility and may lead to problems with soldering and brazing.
Suron offers Semi-bright Electrolytic Nickel Sulfamate with magnetic characteristics, according to QQ-N-290A.
Gold Electroplating
Gold is a precious metal that has excellent corrosion resistance, high electrical conductivity, low electrical resistance, excellent solder-ability, weld-ability, infrared reflectivity and radioapacity. Gold is primarily used in the electrical industry for connectors and printed circuits and in the electronics industry for transistor integrated circuits.
The use of gold in these industries is attributed to the fact that it is the only metal that will meet stringent performance and property requirements in these fields. The excellent physical and chemical properties offset the price of gold.
Hard gold is an ideal connector material, and is useful in applications where good wear resistance is required. Solder-ability of hard gold is very good.
Soft gold is useful in electronic applications where bond-ability or heat resistance is required. Solder-ability of soft gold is excellent up to 400°c, but its purity and softness may limit its use in wear application.
Suron offers:
Soft Gold Electroplating (24 karat) 99.9% purity, over electrolytic or electroless nickel, to meet MIL-G-45204C Type III Grade A, and ASTM B488-01 Type III Grade A .
Hard Gold Electroplating (24 karat) 99.7% purity, over electrolytic or electroless nickel, to meet MIL-G-45204C type I grade C, and ASTM B488-01 Type I Grade C .
Passivation of Stainless-Steel:
Passivation is the removal of exogenous iron compounds, which are potential corrosion sites, from the surface of stainless steel by means of a chemical dissolution. In addition, the passivation process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation (corrosion). The process is recommended for austenitic stainless steels of the 300 series.
Suron offers Chemical Passivation for Stainless-Steel Parts according to ASTM-A967-05 Nitric 2 treatment (equivalent to US Federal Spec QQ-P-35C type VI ).
Suron manufactures precise and highly complex parts made by Electroforming. These parts are produced from Nickel-Cobalt, to tolerances as high as +/-0.015mm. Electroformed parts are highly durable, have a very low internal tension, and are highly corrosive resistant.
The electroforming process has been used in industry for many decades. This is an electrochemical process very similar in principle to electrolytic coating processes, but instead of a thin coating of a few microns, it is used for producing metal parts. The traditional electroforming process produces the form of the negative of the required product from any kind of metal, usually aluminum, and that is the mandrel. The mandrel is used as a cathode on which the nickel is built. At the end of the process the product is removed from the mandrel.
In contrast to the electroforming process, in the Photo-Electroforming process products are manufactured by a combination with a photolithographic process, which is similar in principle to the process used in photo-etching. This combination of the photolithographic and the electroforming processes allows for the manufacture of thin, flat metal parts, without creating internal stress and highly accurate.
Advantages of Electroforming:
The predominant advantage of electroforming is the accuracy achieved with it. The general tolerance is 0.005 mm. Besides it can be used for the production of bores and grooves at a minimal measurement of 0.032 mm. As in etching, here also highly complex forms can be produced as long as its possible to sketch.
Production of Solder Masks:
For the manufacture and assembly of SMT circuits a soldering mask is essential, and the soldering paste is applied to the location of the components on the printed circuit through its apertures. The standard technologies for the manufacture of soldering masks are photo-etching and the laser.
In cases of dense conductors and Micro B.G.A. it is recommended to use soldering masks made by the photo-electroforming method.
Advantages:
Optimal precision.
Trapezoid profile enabling good printing and paste release.
The aspect ratio between the width of the opening and the mask thickness is 1:1 while with other processes its higher and restricts the release of paste when narrow openings are required.
The side of the openings is very smooth allowing for optimal release of paste.
The drawbacks of the photo-electroforming mask are its high price compared to other soldering masks, and its relatively slow production process.
The Laser Department performs precise laser cutting operations on various metals and a variety of non-metallic materials, such as silicon crystals, piezoelectric crystals, and polymers.
Surons lasers utilize a water jet to cool the material being cut. This ability allows us to cut with a minimum of both thermal impact and micro-cracks.
Our expertise, combined with our state-of-the-art laser equipment, enable us to cut materials in variable heights (non-planar); a significant advantage when cutting complex parts requiring this characteristic.
