Micro-Epsilon’s scanCONTROL laser line series supports successful high-speed, inline inspection of IC pins, connectors and contacts

Laser line profile sensors for inspecting IC pins and connectorsManufacturers 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 per cent 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.

Micro-Epsilon’s scanCONTROL LLT2800-25 and LLT2750-25 laser profile scanners are suitable for this type of inspection process. 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 4000Hz, the high-speed laser line sensors of the scanCONTROL series are suitable 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.
