FAQ's
How are rigid PCBs manufactured?
Rigid PCB manufacturing begins with creating the multilayer PCB layout and selecting materials such as high Tg FR4 or aluminum PCB. A PCB manufacturer typically uses precision machinery in a factory to layer and etch the circuits, ensuring a high-density PCB. Final assembly includes drilling, plating, and testing to meet the standards of the high-temperature PCB manufacturer for high-quality electronic product performance.
Which precautions must be taken with a high Tg PCB?
When working with a high Tg board, you must maintain proper temperature control during assembly to avoid damaging the high Tg value material. Consult a high Tg circuit board manufacturer for compatibility with high frequency PCB and high voltage applications. Always take special care to ensure the design matches the requirements of your China customized high led PCB products.
What is the TG value of a PCB laminate?
The PCB Tg value, or glass transition temperature, indicates the point at which the circuit board material transitions from rigid to soft. A high Tg FR4 laminate typically has a high Tg value above 170 °C, making it suitable for multilayer PCB as well as China high density designs. Collaborating with a PCB wholesale factory or supplier like OurPCB ensures access to materials meeting the demands of flexible PCB or high-density PCB applications.
