About this product
A single-layer, single-sided copper-clad PCB blank made from FR2 laminate, measuring 20 x 30 cm. FR2 is a paper-based phenolic laminate, a lower-cost option than glass-fibre FR4 for simple prototype circuits. It suits basic, low-frequency projects that need a large board area.

Frequently asked questions
What is the difference between FR2 and FR4?
FR2 is a paper-based phenolic laminate and is cheaper, but it is more brittle and less suitable for high-frequency or humid conditions. FR4 is a glass-fibre epoxy laminate that is stronger and more stable, which is why it is preferred for most projects.
Can I drill holes in FR2?
Yes, but FR2 is brittle and can crack near the hole. Use sharp drill bits at a moderate speed and apply light, steady pressure.
