Author:Optizone Technology (Shenzhen) Limited Click: Time:2021-11-15 08:00:00


Magnetron sputtering coating machine coating principle for magnetron sputtering, relative to chemical coating method, its advantages are stronger adhesion of the film layer, tensile test after welding is greater than 10N;  Better uniformity;  The obvious pinholes and bumps can be seen in the chemical coating under 45 times microscope, while there are no pinholes and bumps in magnetron sputtering.

 

Magnetron sputtering coating method because of the production process always keep vacuum, so no secondary pollution.  The following figure shows the actual device.

l  The existence of a pinhole causes welding to form air cannon and virtual welding, which mainly affects the air tightness of the product. 

l  The existence of a spherical particle can increase the assembly error with metal tube, which affects the efficiency of debugging. 

l  Lent uniformity refers to the consistency of film thickness. Poor uniformity leads to great stress changes in different areas of the product at different temperatures, and its performance directly affects the stability of extinction ratio. 

 

In addition to the above advantages, magnetron sputtering coating machine simple gold-plating capacity of 40,000 + root/month, and coating types, including cover all metals, typical coating Cr, Ti, Ni, Au.  Also can be mixed coating, such as Ni and Au, Ti and Au and Cr. 

Magnetron sputtering coating machine of obvious advantages, has been in high power and polarization-maintaining device for product research and development orientation of Optizone, the recent introduction of magnetron sputtering coating machine and after r&d staff of verification, complete the high accuracy grinding machine, series products of magnetron sputtering plating also formally put into production, the product series are as follows: 

01 Gold Plated High Reflection Glass

 

Advantage: 

l  Giganogenic metal film has excellent quality and strong corrosion resistance. 

l  X-ray gold-plated film is homogeneous and compact, the film layer is smooth and dense, and there is no pinhole under microscope. 

l  Lends high firmness adhesion (better than evaporation machine), high adhesion with substrate, precise coating control; 

l  Effective area of monolayer: 50X50mm, gold target purity 99.99%. 

 

The test data is as follows:

02 Metallized sapphire window

Metallized sapphire window piece is a new window piece made of chrome, nickel and gold plating on the edge of sapphire window piece. The edge of metal film can be directly welded or connected to optical mechanical assembly to achieve sealing effect. 

Applications: optical communication, laser window, infrared imaging system, medical equipment, etc. 

 

Advantage: 

Comply with mil-STD-883 weldability standard; 

Metallized materials can be customized: Cr, Ti, Ni, Au, etc. 

 

03 Infrared optical window

 

 

Advantages:

According to customer custom gold-plated Si substrate, Ge substrate; 

The transmittance of 1~6.8μm is low, and the transmittance of 7.5~14μm is high. 

Metallized film can be plated for welding. 

Application: uncooled infrared detectors 

04Metallized ribbon fiberMetallized optical fiber

 

The optical fiber or other waveguide materials are metallized to achieve the full metallized airtight packaging of optical devices. 

The lenticular optical fiber grinding machine used for bevel, microlens and wedge optical fiber is completely independently developed and can be modified according to different product structure.  Can produce a variety of requirements of optical fiber. 

The optical fiber processed by this equipment has high precision, the Angle error is within 1°, the size error is controlled within 1 micron, the end quality is good, no scratches, pitting observed under 400 times the end detector. 

Applications: high-speed trunk line communication, submarine communication, military defense, aerospace, optical fiber communication, optical fiber sensing 

Advantages: good adhesion; 

Good weldability, can withstand 280℃ solder 30 seconds welding; 

Gold plating thickness ≥0.1μm; 

High tensile strength (thermal resistance welding process tensile force up to 10N); 

Instead of polymer material link scheme, solve the problem of easy aging, creep, high temperature resistance and so on.

Remark: 

Linear conical Angle error mainly refers to the conical included Angle of microlens fiber. For single mode, the higher the precision, the higher the yield of machining curvature.  For multi-mode fiber, the higher the accuracy of taper, the better the consistency of coupling efficiency. 

The angular error mainly refers to the included Angle of the wedge-shaped lens fiber, and the higher the precision, the higher the yield of the curvature processed.  For multi-mode fiber, the higher the accuracy of taper, the better the consistency of coupling efficiency. 

The higher the curvature precision is, the higher the coupling efficiency is. 

The smaller the eccentricity, the smaller the included Angle between the optical axis of the lenticular fiber and the fiber cladding axis, thus facilitating coupling debugging and improving production efficiency. 

A large tension scheme reduces the rate of breakage caused by misuse of a product, making it more adaptable to use situations. 


The End 

With the development of science and technology, people have higher and higher requirements for product quality and service life. The traditional adhesive packaging technology can not be used stably in the harsh environment, and the glue sealing is poor, moisture and air are easy to cause oxidation corrosion of the device, reducing the service life of the device;  Metallized welding package can better solve the aging problem of devices caused by air tightness, and for the sealing of some precision devices can only use metal welding, with more and more mature metallized technology, its application will be further developed.
