Laser line profile sensors guarantee quality of IC pins and connectors

Manufacturers of printed circuit boards (PCBs) are successfully using laser profile sensors from Micro-Epsilon to inspect integrated circuit (IC) pins, connectors and contacts immediately after production. The sensors detect the presence of the pins and connectors, as well as their completeness, length and swash circumference.

In the production of IC pins, connectors and contacts, manufacturing quality is absolutely critical. This means that all connectors and contact strips must be subjected to 100% inline inspection. Connectors that are either too short or pins that are bent can result in errors or interference with the contacts. Connectors must therefore be inspected immediately after production and any defective parts removed from the process.

For this type of inspection process, Micro-Epsilon’s scanCONTROL LLT2800-25 and LLT2750-25 laser profile scanners are ideal. For very small connection plug boards, the LLT2800-10 system is the preferred choice due to its high resolution.

During the production process, the connection plug board to be inspected is guided under the laser line of the scanner. A height profile is then generated in 3D, which is subsequently evaluated by high performance evaluation software using a standard industrial PC or laptop. Depending on the condition of the IC pins, the measurement can either be carried out directly on the top of the pins or by using ‘master plates’ that generate the precise height profile of the pins using small plungers.

Due to their high resolution and high profile frequency of up to 4,000Hz, the high speed laser line sensors of the scanCONTROL series are ideal for high speed, inline inspection tasks. The sensors work on the laser line triangulation measuring principle, operating at up to 1.2 million measurement points per second.

Micro-Epsilon (www.micro-epsilon.co.uk) is a major global manufacturer of sensors, headquartered in Germany. The company’s range of displacement sensors measure everything from to distance, position, vibration, dimensions and thickness, using both contact and non-contact measurement techniques. These techniques include 1D, 2D and even 3D laser-optical sensors and systems, eddy-current, capacitive, LVDT & inductive, potentiometric and draw-wire principles. Additionally Micro Epsilon has developed its own range of non-contact infrared temperature sensors that can measure virtually any target temperature from -40 to +3,300°C.

With more than 35 years’ experience in the industry, Micro-Epsilon isn’t just a sensor manufacturer. The company is highly innovative and understands the importance of providing complete solutions and support services for its customers. The firm is renowned for its expertise in consulting, development and application of industrial sensors to complex, customer-specific solutions for measurement, inspection and automation. The focus is on selling technical advantage to its customers.
