Gold finger is commonly used to connect circuit boards of electronic devices and other electronic devices. It has the advantages of high precision, high reliability and high stability, and is widely used in electronics, communications, computers, automotive and other industries.
With the rapid development of electronic science and technology, the performance requirements and dimensional requirements of gold fingers are getting higher and higher. Therefore, it is necessary to carry out high-precision measurements on various parts of the gold finger to control product quality, improve product performance and reduce customer complaints.
一、Structural Components of GoldfingerGold Finger is usually made of metal material with elongated shape, similar to a finger, and plays an important role in the field of electronics. It realizes circuit connection through metal contact, which can reliably carry out current transmission and ensure the normal operation of equipment. Gold Finger is mainly composed of two parts: the shrapnel and the base. Shrapnel is usually made of elastic metal materials such as phosphor bronze, copper alloy, etc., with a certain degree of compression and elasticity, which can be adapted to different connection environments and pressure. The base is usually made of metal or plastic material, which is used to fix the shrapnel and connector.
二、Functional Uses of GoldfingerGold fingers are widely used in electronics, communications, computers, automotive and other industries. Different products in different industries have different product functions and requirements for gold fingers.
In the electronics industry, gold fingers are used to connect circuit boards and other electronic equipment to realize the transmission and control of signals and circuits to ensure the normal operation of the equipment. In TVs, cell phones, computers and other devices, gold finger connectors can transmit audio and video signals to the display or speakers to realize the audio and video playback function.
In the communications industry, gold fingers are used to connect antennas and circuit boards for transmission and reception of wireless signals.
In computer equipment, gold fingers are used to connect the hard disk to the motherboard for reading, writing and storing data.
In automotive equipment, gold fingers are used to connect electronic control modules and sensors for control and monitoring of the vehicle.
三、What are the precision measurement needs of gold fingers?There are numerous gold-colored conductive shrapnel for gold fingers. Different applications and products also have different requirements on the material, quantity, contact area, height and plating thickness of gold finger shrapnel, so it is necessary to carry out precision measurements of gold finger shrapnel so as to detect whether the gold finger meets the design requirements.
Size Measurement：Measure the length, width, height and other dimensional parameters of the gold finger shrapnel to ensure that it meets the design requirements. Among them, the accuracy of the height of the gold finger shrapnel has an important impact on the connection and stability of the gold finger. If the height of the shrapnel is inaccurate, it may lead to poor connection, signal interference and other problems, thus affecting the performance and stability of the device.
Surface Roughness Measurement：Measure the surface roughness of gold finger shrapnel to ensure the quality of its contact with other equipment.
Conductive layer thickness measurement：Measure the thickness of the conductive layer (e.g. metal plating) of gold finger shrapnel to ensure its conductivity and corrosion resistance.
四、Atometrics Goldfinger Shrapnel Height Inspection ExampleRecently, an enterprise wants to detect the height of the distance from the gold finger shrapnel to the reference surface, so as to control product quality, improve production efficiency, and reduce customer complaints. atometrics engineers received the customer's inspection needs, and chose the 3D Line Laser Measuring Instrument AR-7020 to make the measurement program, and some of the measurement results are shown below:
After the measurement is completed, the software can analyze and process the measurement results to determine if the gold finger shrapnel height meets the standard requirements. It also has statistical analysis functions, such as calculating the average value and standard deviation, to assess the accuracy and stability of the measurement results.
After receiving the inspection report, the customer was very satisfied with the fineness of the product image scanned by the 3D line laser measuring instrument, and the intuitive and precise value of the required shrapnel height.
Taking this opportunity, UcoTest also hopes to help more enterprises, universities and research institutes to solve their testing problems!Atometrics 3D Line Laser Measuring Instrument AR-7000 series is a non-contact measuring equipment based on laser technology, which can detect the contour of samples, defects, flatness, flatness, height difference and so on.Atometrics 3D Line Laser Measuring Instrument AR-7000 series utilizes 3840 dots to finely render product shapes, dramatically improving image quality and refinement.At the same time, it has powerful software functions with a variety of 3D detection tools and algorithms; it can also perform multi-head splicing to meet the needs of many different splicing scenes.
