Judging from appearance
1. Weld Appearance
With the numerous parts on a PCB circuit board, it is crucial for the welding to be done securely to prevent parts from falling off easily, which can greatly impact the overall quality and appearance of the circuit board.
2. Dimension and Thickness Standards
PCBs come in different thicknesses as per standard rules. Users can measure and verify according to their specific requirements.
3. Light and Color
The external PCB circuit boards are typically covered with ink for insulation. A dull color indicates a lack of ink, which can affect the quality of the insulation board itself.
Judging from the board
1. HB board is inexpensive but prone to deformation and breakage, suitable for single panels with a deep yellow component surface color and a rough, thin copper coating.
2. Single-sided 94V0, CEM-1 boards are relatively more expensive than cardboard, with a light yellow component surface color, commonly used for industrial and power boards with fire rating requirements.
3. FR4 boards have a high cost and good strength, with a green double-sided appearance. Most PCBs are made from this material, offering precise and fine copper coating, albeit being heavier than unit boards. The printing ink on PCB circuit boards should be smooth, with no false wire dew copper or bubbling.
