With the rapid development of the mobile phone, electronics, and communication industries, the PCB board industry has seen continuous and rapid growth. As people demand more layers, precision, materials, colors, and reliability in components, the industry has faced challenges.
Market price competition has increased the cost of PCB board materials, leading to manufacturers cutting corners to offer low prices and improve competitiveness. However, these cost reductions often result in inferior products with reduced reliability and performance, affecting solderability and overall quality.
To distinguish quality PCB boards, one can assess through appearance and quality specifications. Here’s how to judge the quality of PCB circuit boards:
Firstly, consider the appearance of the board. Analyze the appearance through three aspects:
1.1 Light and color: Insulation quality can be determined by the brightness and amount of ink on the board.
1.2 Size and thickness: Check if the thickness matches the standard and product specifications.
1.3 Welding quality: Poor welding can lead to parts detachment, impacting board performance.
Secondly, ensure the PCB meets these requirements for high quality:
2.1 Copper surface should resist oxidation.
2.2 Components should connect easily post-installation.
2.3 Copper skin must withstand high temperatures.
2.4 Line dimensions should prevent overheating, breaking, and short circuits.
2.5 Avoid additional electromagnetic radiation.
2.6 Consider resistance to high temperatures, humidity, and special environments.
2.7 Prevent shape deformation to maintain proper installation alignment.
2.8 Mechanical properties of the surface should meet installation requirements.
