Shenzhen Prin Circuit, as a high-tech enterprise providing one-stop high-end circuit board services from R&D to mass production, understands that the stability and reliability of circuit board quality are key to product success. To ensure that each circuit board meets the highest quality standards, Shenzhen Prin Circuit has introduced a series of precision testing equipment. This article will introduce some of them to see how they strictly control the quality of circuit boards from various aspects.
1. Impedance Tester
The impedance tester can quickly and accurately measure the impedance values between any pins on the circuit board and between the pins and the casing, ensuring the stable and reliable signal transmission performance of the circuit board. Shenzhen Prin Circuit utilizes the impedance tester to strictly control the impedance characteristics of the circuit boards, thus ensuring the stability and reliability of the circuit boards in high-frequency applications.
2. Inductance and Resistance Tester
The inductance tester used by Shenzhen Prin Circuit not only has precise inductance measurement capabilities but can also measure the resistance parameters on the circuit board. This dual functionality allows Shenzhen Prin Circuit to gain a more comprehensive understanding of the electrical characteristics of the circuit boards during the production process, ensuring the stability and reliability of the circuit boards in various application scenarios.
3. High Voltage Tester
For thick copper boards that have extremely high requirements for high voltage, such as 5000V circuit boards, Shenzhen Prin Circuit uses high voltage testers for inspection. This tester can simulate a high voltage environment to conduct strict electrical performance tests on the circuit boards, ensuring the reliability and safety of thick copper boards in various high voltage application scenarios.
4. Coating Tester
The coating tester is a key tool for Shenzhen Prin Circuit to ensure the surface treatment thickness of the circuit boards. It can accurately measure the thickness of gold plating, nickel plating, tin spraying, silver immersion, nickel-palladium gold, and other surface treatments, ensuring that these coatings meet the established standards. This not only enhances the surface durability of the circuit boards but also improves their reliability and stability in high-frequency applications.
5. Ion Contamination Tester
Ion contamination is one of the important factors affecting circuit board quality. Shenzhen Prin Circuit uses ion contamination testers to accurately detect the content and types of ion contaminants remaining on the surface of the circuit boards, thus evaluating the effectiveness of the cleaning process during production and optimizing the cleaning procedures in a timely manner to ensure that the cleanliness of the circuit board surfaces meets the highest standards.
6. Metallographic Microscope
The metallographic microscope can magnify the microscopic structure of the circuit boards, helping engineers and operators to examine key parameters such as hole copper, surface copper, solder mask thickness, and inner layer copper thickness in detail. Through observations with the metallographic microscope, Shenzhen Prin Circuit can promptly identify and rectify potential defects, ensuring the quality and reliability of the circuit boards.
7. Soldering Oven
The soldering oven is an important means of assessing the solderability of circuit board surfaces. Shenzhen Prin Circuit conducts soldering oven tests to evaluate the performance of circuit boards during the soldering process, ensuring that the circuit boards have good soldering performance and reliability in practical applications.
8. Copper Foil Tensile Tester
This tester is used to evaluate the bonding strength between the circuit board and the copper foil. Shenzhen Prin Circuit ensures a strong and reliable connection between the circuit board and the copper foil through the copper foil tensile tester, avoiding circuit failures caused by copper foil detachment.
9. 2D Tester
The 2D tester is a key tool for Shenzhen Prin Circuit to ensure the dimensional accuracy of circuit boards. It can accurately measure key parameters such as the distance from holes to the edge of the board, hole diameter, angles, line width and spacing, and hole position accuracy, ensuring that the circuit boards meet the highest dimensional accuracy requirements during production.
10. AVI Appearance Inspection Machine
The AVI appearance inspection machine is an important device for Shenzhen Prin Circuit to achieve efficient and accurate appearance inspection. It uses visual systems, image processing technology, and artificial intelligence algorithms to conduct comprehensive and accurate checks on the appearance of circuit boards, accurately identifying common issues such as pad defects and circuit breaks, ensuring the appearance of the circuit boards is flawless. The application of the AVI appearance inspection machine has significantly improved the production efficiency and product quality of Shenzhen Prin Circuit.
11. Flying Probe Tester
The flying probe tester automatically and quickly touches the test points on the circuit board according to preset test programs using movable probes to detect electrical characteristics such as open/short circuits, resistance (four-wire flying probe tester), and capacitance. The application of the flying probe tester ensures that the circuit boards produced by Shenzhen Prin Circuit meet the highest electrical performance standards.
Shenzhen Prin Circuit conducts strict quality control of circuit boards from multiple dimensions through a series of advanced testing equipment and technologies. The application of these devices not only improves the production efficiency and product quality of Prin Circuit but also provides customers with more reliable and durable circuit board products.
