Material selection: Choose high-strength, high-rigidity materials for rigid circuit boards, such as fiberglass and ceramic plates.
Use reinforcement materials: Incorporate reinforcement materials at the board’s bottom to enhance surface strength.
Hot pressing treatment: Employ a hot press machine to shape the circuit board under high temperature and pressure, preventing warping.
Use multi-layer boards: Opt for multi-layer boards over single-layer ones to minimize warping risks and enhance strength.
Use plate supports: Install plate supports beneath the board to bolster surface stability.
Nickel metallization: Apply nickel metallization treatment during manufacturing to boost mechanical strength and stability.
Thickness control: Ensure strict control over the thickness of rigid circuit boards to maintain adequate rigidity.
Consistent substrate thickness: Use substrates with uniform thickness to prevent potential board warping issues.
Soldering temperature control: Precisely regulate soldering temperatures to prevent rigid circuit board deformation caused by excessive heat.
Fix with brackets: When using the board, brackets or fixing clips can be utilized to secure the board in place and prevent warping due to mechanical vibration and other factors.
Manual bending correction: If the circuit board has already warped, manual bending can be used for correction. However, attention must be paid to the force and angle applied to avoid damaging the circuit board.
Copper foil thickness: Increase the thickness of copper foil appropriately to enhance the strength of the board.
Use metal foil reinforcement: When designing a rigid circuit board, consider adding metal foil reinforcement at the board’s edges to increase its strength and stability, thereby preventing warping.
Control the moisture content of the board: During circuit board manufacturing, it is crucial to control the moisture content to prevent board deformation caused by excessive moisture.
Use consistent copper foil thickness: Inconsistent copper foil thicknesses can also lead to warping, hence ensure uniform copper foil thickness throughout the circuit board.
For large areas of copper foil, add an isolation layer underneath to minimize warping potential.
Pay attention during circuit board installation: Avoid over-tightening screws or fixtures to prevent circuit board warping.
Cabling planning: Ensure wiring planning is done sensibly to avoid local over-density or concentration, which can create uneven pressure on the board surface.
PCB design: When designing the PCB shape, avoid overly complex geometries to prevent uneven force distribution on the board surface. Increase drilling diameter appropriately during design to avoid board deformation caused by insufficient drilling size.
Reinforced supports: Incorporate reinforced supports around critical points of the board to enhance overall rigidity.
Control soldering and ambient temperatures: Manage soldering temperature and duration to prevent circuit board deformation due to excessive heat or prolonged exposure. Throughout manufacturing, assembly, and operation, maintain ambient temperatures within optimal ranges to mitigate adverse effects on the circuit board.
Utilize brackets: During manufacturing, employ pressure plates to compress the circuit board, ensuring a flat surface. During assembly, use brackets or fixtures to prevent deformation caused by uneven pressure on the plate. Strengthen the packaging of circuit boards during transportation and storage to safeguard against external impacts.
Regular inspection: Routinely inspect the condition of circuit boards, promptly identifying and addressing any warping issues.
