Products Description
FR4 TG170 Immersion Gold PCB is a high performance printed circuit board (PCB) that combines the excellent electrical insulation properties of FR4 material with the high reliability of the immersion gold process. The following is an introduction to the properties of FR4 TG170 Immersion Gold PCBs and processing considerations:
FR4 TG170 Immersion Gold Circuit Board Performance Introduction:
High Heat Resistance: TG170 indicates that the glass transition temperature (Tg) of the board reaches 170°C, which means that the board can maintain stable physical and electrical properties at high temperatures, and is suitable for lead-free soldering and other high-temperature processes.
Excellent Peel Strength: The immersion gold process provides excellent peel strength, ensuring the reliability of the board under thermal cycling or mechanical stress.
Low CTE (Coefficient of Thermal Expansion): Low Z-axis CTE values mean better dimensional stability of the board during temperature changes, contributing to improved performance of the assembled device.
Chemical Resistance: FR4 materials have good resistance to a wide range of chemicals, making them suitable for use in harsh environments.
Excellent CAF (Conductive Anode Filament) Resistance: CAF is a common board failure mode, and TG170 boards have improved CAF resistance through material and process optimization.
UV Blocking and AOI Compatible: UV Blocking reduces UV damage to the board, while AOI (Automated Optical Inspection) compatibility ensures that the boards can be inspected for effective quality during the manufacturing process.
Low Water Absorption: Low water absorption helps maintain the board’s dimensional stability and electrical properties.
Excellent Dimensional Stability: TG170 boards maintain good dimensional stability in environments with temperature and humidity variations.
FR4 TG170 Immersion Gold PCB Processing Precautions:
Drilling: The drilling process should pay attention to the choice of drill bit and speed control to prevent damage to the FR4 material in the drilling process.
Immersion Gold Process: The key to the immersion gold process is to control the time and temperature of the chemical gold plating to ensure the uniformity and thickness of the plating layer on the surface of the FR4 material.
Lamination Process: The lamination process should control the temperature, pressure and time to ensure that the FR4 material is fully bonded with other materials.
Environmental Control: Processing in a constant temperature and humidity environment to minimize the impact of environmental factors on the performance of the sheet.
Operation Norms: Develop and follow standardized processing procedures to ensure consistency and repeatability of operations.
Safety Protection: Operators must wear complete safety equipment, including protective glasses, dust masks, gloves, etc.
Tool Selection: Select the appropriate processing tools, such as diamond blades, according to the characteristics of FR4 sheets to improve processing efficiency and quality.
Warp and Weft Utilization: Make full use of the warp and weft characteristics of FR4 sheet to optimize the processing scheme and improve the material utilization and mechanical properties of PCB.
Data Recording: Record all parameters in the processing process in detail to provide a basis for subsequent analysis and improvement.
Waste Management: Reasonable classification and recycling of waste materials to reduce the impact on the environment, while creating conditions for the recycling of materials.
