Micro-Epsilon offers laser profile sensors for use in manufacture of printed circuit boards
Scancontrol series of laser profile sensors
Manufacturers of printed circuit boards (PCBs) can use Micro-Epsilon’s Scancontrol series of laser profile sensors 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.
According to the company, to ensure manufacturing quality, all connectors and contact strips must be subjected to 100 per cent inline inspection. For this type of inspection process, the Scancontrol LLT2800-25 and LLT2750-25 laser profile scanners are particularly useful.
For very small connection plug boards, the LLT2800-10 system is said to be the best option thanks 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 then evaluated by 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 top of the pins or by using ‘master plates’ that generate the precise height profile of the pins using small plungers.
- The Scancontrol sensors work on the laser line triangulation measuring principle, operating at up to 1.2 million measurement points per second.
The OptoNCDT 2300LL non-contact laser line displacement sensor from Micro-Epsilon is designed for the high-speed measurement of shiny metallic and rapidly changing, rough or other difficult-to-measure surfaces. An ideal application for the sensor is said to be structured surfaces where the distance to the surface and not the structure itself needs to be measured.
Micro-Epsilon has developed an inductive LVDT gauging sensor suitable for use in medium- to high-volume OEM production environments. The sensor’s small size enables it to be installed in areas where space is tight or restricted. The Indusensor DTA-XG8 probe is designed specifically for process automation, machine tools, automated assembly and quality-control applications in industries such as automotive and aerospace.
Micro-Epsilon has introduced the ConfocalDT IFS 2405 series of confocal chromatic sensors for measuring the displacement or position of dark, diffuse and highly reflective surfaces. The sensors are designed for research and development, laboratory, medical, semiconductor manufacturing, glass production and plastics processing applications.
The Thermometer CSmicro from Micro-Epsilon is a non-contact infrared temperature sensor designed for installation where space is restricted. The sensor utilises a small sensor head with compact electronics fully integrated into the sensor cable and is suitable for OEM and medium- to high-volume applications.
Micro-Epsilon has extended its range of non-contact temperature sensors to include a compact infrared ratio temperature sensor suitable for use in high-speed, high-temperature environments, including those found in metal casting, welding, forming and sintering.
