Resistance copper paste: a new choice to replace traditional resistance materials

Brief introduction

With the continuous development of electronic technology, the performance and application requirements for resistive materials are also constantly increasing. Resistance copper paste, as a new type of resistance material, has unique performance advantages and has shown the potential to replace traditional resistance materials in multiple fields. This article will explore in detail in which fields resistance copper paste can replace traditional resistance materials, and explain it with data. At the same time, it will introduce the advanced technology of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB5105 Resistance Copper PasteThe application situation in these fields.

2、 Characteristics of resistance copper paste

Resistance copper paste is mainly composed of copper powder, binder, additives, etc. Copper, as the main component, endows the resistance copper paste with good conductivity. Compared with traditional resistance materials, resistance copper paste has characteristics such as printability and low-temperature sintering, which can adapt to different processing techniques and application scenarios.

3、 Fields that can replace traditional resistance materials

（1） Printed electronics field

1. Flexible electronic devices
   • In flexible electronic devices such as flexible circuit boards and wearable devices, traditional block resistor materials are difficult to meet the flexibility requirements of the equipment. Resistance copper paste can directly form resistance lines on flexible substrates through printing technology. For example, in the manufacturing of flexible circuit boards, when using traditional metal film resistors, due to their rigid structure, the resistance value may fluctuate by more than 20% when the bending radius is less than 5mm, resulting in unstable circuit performance.

2. Large area electronic devices
   • For the manufacturing of large-area electronic devices such as large display screens, solar cells, etc., the installation and wiring of traditional resistive materials are relatively complex. Resistance copper paste can achieve large-area and high-precision resistance pattern preparation through printing technology. Taking a large display screen as an example, when using traditional wire wound resistors for voltage division and other functions in the circuit, due to their discrete component characteristics, it will increase the complexity and volume of the circuit when wiring over a large area. By using resistance copper paste, a complex resistance network can be formed through a single printing process, reducing wiring space by about 30% -40% and improving production efficiency and device integration.

（2） Automotive electronics field

1. Automotive sensors
   • Automotive sensors need to work stably in complex environments such as high temperatures, vibrations, etc. Traditional carbon film resistors have a large temperature coefficient of resistance in high temperature (above 120 ℃) environments, which may lead to increased measurement errors. For example, in automotive engine temperature sensors, when the temperature changes from -40 ℃ to 150 ℃, the resistance value of traditional carbon film resistors may change by ± 15%. The resistance element made of YB5105 resistance copper paste from Yanbo brand can control the resistance value change within ± 8% within the same temperature range, which can more accurately reflect temperature changes and improve the accuracy and reliability of the sensor.
2. Automotive electronic control system
   • In automotive electronic control systems, such as engine control units (ECUs), braking systems, etc., a large number of resistance components are required. Traditional thick film resistors may experience issues such as loose solder joints and resistance drift in high vibration environments (such as vibration acceleration exceeding 5g).Resistance copper pasteDue to its good adhesion and compatibility with the substrate, the resistance drift can be controlled within ± 3% in high vibration environments (compared to ± 5% -8% for thick film resistors), which can better meet the stability requirements of automotive electronic control systems.

（3） In the field of consumer electronics

1. Smartphones and tablets
   • Compact space is an important design limitation in smartphones and tablets. Traditional patch resistors, although small in size, require more precise resistance values and better high-frequency performance in some special circuits, such as matching resistors in RF circuits. By optimizing the formula and process, the YB5105 resistor copper paste from Yanbo brand can achieve higher resistance accuracy (with an error within ± 1%, compared to ± 5% of traditional surface mount resistors), and at high frequencies (such as 2.4GHz frequency band), the insertion loss can be reduced by about 2-3dB, which can improve the performance of RF circuits. At the same time, due to its printability, it can be more flexibly laid out on circuit boards, saving space.
2. Audio equipment
   • In audio devices such as headphones, speakers, etc., the noise characteristics of resistors have a significant impact on sound quality. Traditional metal oxide film resistors may generate certain thermal noise in small signal amplification circuits. The resistor made of YB5105 copper paste from Yanbo brand can reduce thermal noise by about 30% -40% in the same audio circuit, which can improve the purity of audio signals and enhance sound quality.
