Laser trimming technology of potentiometer
The laser trimming technology of potentiometer can perfectly realize the high precision, high efficiency and multifunction laser trimming. Compared with the traditional grinding method, laser engraving has a significant advantage in the precision, efficiency and multi function development. It is a breakthrough technology for production!
Potentiometer laser engraving has the following technical characteristics:
1) High precision and high efficiency: As an effective means of precision machining, industrial laser applications have been used in more and more fields, and laser ablation can be used to obtain very high resistance precision, thus achieving a higher degree of linearity. Potentiometer laser trimming technology uses high precision measurement and control system software, with the laser trimming technology unique, independent linearity trimming potentiometer can reach 0.1% or so, up to 0.05% (independent linearity trimming and material properties and initial linearity related). The total resistance of the target can be controlled at about 0.2%. As for the efficiency, the average single chip repair time is about 10 seconds, the production efficiency is the traditional grinding equipment of 4 to 5 times, greatly improving the production efficiency.
2) Powerful: Laser repair using high-precision measurement and control system and operating software, with a powerful function to expand, to meet the special needs of customers, for example:
A)Symmetry correction: Can be done from any angle as the center of the starting position, do the symmetry of resistance to repair, the minimum angle measurement accuracy of 2 '.
B)Resistance correction of arbitrary curve: The curve of trimming can be arbitrary function in arbitrary angle range, with angle control and the curve of high resolution real-time follow trimming technology can ensure the
smooth transition between different segments, the requirements to achieve the objective function;
3) The equipment has a wealth of measurement functions, such as: clearance measurement, symmetry measurement function, to meet the requirements of the technical specifications of potentiometer production quality control;
4) Trimming system with laser engraving software, patented technology. It is powerful, simple operation, can achieve any angle point trimming and manual trimming, according to customer requirements to achieve a more flexible trimming mode and process requirements;
5)The coaxial video system, which is designed and developed independently, can be adjusted automatically with high pixel industrial camera. It can reduce the human error and improve the production efficiency.
