Laser trimming is widely used in the electronics industry at present. 200mw laser pointer fine-tuning of resistors and capacitors makes it extremely small in thermal impact on the adjacent components when processing, and does not produce pollution. It is easy to be computer-controlled and has the advantages of fast speed, high efficiency and continuous monitoring and other advantages, compared with conventional fine-tuning method, but also has high precision, good reproducibility and resistance does not change over time characteristics.
Laser trimming is widely used to fine tune the parameters of thick, thin film components and circuits, including resistors, capacitors, quartz resonators, parameter tuning of monolithic filters, hybrid integrated circuit amplifiers, voltage dividers, current stabilizers, digital simulations and simulations Digital converters, high frequency oscillators, operational amplifiers, quartz crystal devices (including oscillators, filters), and fine tuning of semiconductor integrated circuits, eliminating the limitations that affect the accuracy of multiple integrated circuits.
Because the laser beam can be precisely oriented, positioned within the minimum size area, and combined with a small thermal area of action in the specified form, precision thin-film elements can be fine-tuned because there is no intermediate (chemical) process in the process and can be performed in the atmosphere In the processing, so real-time test results, and 50mw laser pointer processing process to achieve automation, with high precision, process is simple and efficient features.
The sensor is a kind of detection device that can sense the information to be measured and transform the sensed information into electrical signals or other desired forms of information output according to certain rules to meet the requirements of information transmission, processing, storage and display , record and control requirements.
Sensor features include: miniaturization, digital, intelligent, multi-functional, systematic, networked. It is to achieve automatic detection and automatic control of the most important part. The existence and development of sensors, so that the object has a sense of touch, taste and smell and other sensory, so that objects slowly become alive again. Usually according to their basic perception function is divided into ten categories of thermal components, photosensitive components, gas sensors, force sensors, magnetic sensors, humidity sensors, acoustic sensors, radiation sensitive components, color sensors and taste sensitive components.
With the development of science and technology, sensor applications are also more and more widely, but with the resistance of the sensor components resistance accuracy can not be effectively controlled, many manufacturers choose to manually adjust the resistance, so that not only the accuracy Less than the guarantee, and the efficiency is still very low; a new type of 500mw laser pointer resistance device to solve this problem, the successful application of laser resistance in the sensor industry, to solve the problem of low efficiency, low accuracy, for the majority of production manufacturers save costs.
