How Does Laser Displacement Sensor Detects Multilayer PCB Overlap | SinceVision

In the manufacturing of electronic products, PCB boards are the support of electronic components and the key to electrical connections. Their quality directly affects product performance. Due to the extremely thin thickness of PCB boards, overlapping problems are prone to occur on the machine, resulting in the generation of waste. Combined with the jitter of the machine during movement, traditional detection methods cannot accurately and stably detect the multi-layer overlap of PCB boards, which in turn affects the company's production efficiency and product quality.

PCB Multi-layer Overlapping Detection Solution

The detection distance of SinceVision SD-C030 laser displacement sensor is 30mm, the range is ±5mm, the sampling frequency is 100- 1000Hz, and the linearity is ±0.1% of FS. The spot diameter is Φ50μm. In addition, it also supports multiple communication methods such as RS-485 communication and analog voltage/current output, which facilitates data interaction with the host computer.

SinceVision SD-C030 laser displacement sensor adopts an extra-large front output indicator light design, allowing operators to grasp the detection status in real time, thereby improving production visualization and process controllability.

When it is detected that the board thickness change exceeds the set threshold, the sensor will trigger an audible and visual alarm, effectively blocking the PCB boards with abnormal lamination from entering the next process, helping production line personnel to quickly locate and troubleshoot faults, and providing reliable guarantees for continuous production.

SD-C030 Laser Displacement Sensor

SD-C series laser displacement sensors adopt an ultra-compact size of 44×25×20mm and a lightweight design. They can be easily installed on narrow or complex mechanical structures, meeting the company's needs for miniaturization and integration of equipment. Their fast response and precise detection features, combined with the advantages of easy operation and maintenance, can provide companies with timely and reliable production data, help optimize production processes, improve production efficiency and product quality, and in the long run reduce the company's overall operating costs and improve economic benefits.
