Ahead of the Curve: The Future of 3D Optical Inspection


era and projector setups is not a long-term solution. New multifunctional sensors that can be applied to a broader range of 3D optical inspection and measurement application are raising the bar for the electronics and semicon- ductor markets. CyberOptics’ customers span a variety of

different vertical sectors, from consumer elec- tronics to aerospace, automotive and medical devices. The needs of these different customers are actually quite similar, whether it be for automated optical inspection (AOI), solder- based inspection, semiconductor inspection, or parts inspection. In each case, the customer is looking to improve operating efficiencies, pro- duction yields and quality. As a company, CyberOptics develops and


manufactures high-precision 3D sensors for the industrial metrology, SMT and semicon- ductor markets. The company’s proprietary, advanced sensor technology sharpens the cus- tomer’s competitive edge as the demand rises for higher accuracy at faster production speeds.


Key Market Drivers In the SMT market, main drivers include


the decrease in size of electronics packaging and the increase in density of PCBs, challenges from tall components near very small components, and complex applications. There is definitely a greater need for precision, accuracy and speed that continues to shift the market toward 3D optical inspection.


CyberOptics’ CMM excels at socket metrology, measuring thousands of pins in around 10 seconds.


has successfully demonstrated capabilities far beyond those of its competitors. CyberOptics’ 3D multiple reflection suppres-


sion (MRS) sensor technology has proven effective for flux inspection, wirebond inspection, die-attach applications, shiny flip chip packaging, microelec- tronics, sub-100-micron solder paste deposits, very small LEDs, micro-LEDs, paste printing onto chip products, socket metrology, molded parts inspec- tion, and various other complex applications. MRS is a technology that enables metrology-

grade accuracy by inhibiting optical measurement distortions and reflections. Essentially, it digitally “tags” the light to ensure that multiple reflections are suppressed, allowing high-quality meas- urement and inspection. This is vastly different from what our


competitors are doing. Their systems typically comprise a single camera and multiple projec- tors in series, but CyberOptics’ solution revers- es that by incorporating multiple cameras and a digital projector. The secret sauce, however, is really the algorithms. The fact that MRS technology is now at


the heart of the world’s smartphone manufac- turing inspection and increasingly used in var- ious applications where high accuracy and speed are vital, underscores its importance. CyberOptics has been pioneering optical


sensing technology for three decades, due to its sensor expertise, sophisticated algorithms, rich patent portfolio, and continuous advance- ment. Its core technology, MRS sensors, enable microscopic-level inspection at production speeds and are deployed in all target market segments. The company has invested a great deal in this


technology and believes that it is a class apart when compared with alternative technologies. Customers value the significant advantages and benefits to their yields and productivity.


Coordinate Measurement Demand is growing for fast, accurate, x, y and


z measurements of circuits and devices. This is the case regardless of whether the manufacturer is
