2" x 3" FR1 Substrates

$14.99SKU: 1000279

If you are going to be drilling, we recommend drilling on FR1 substrates.

Unlike FR4, FR1 dust does not contain fiber glass which can be harmful to your lungs. It is also a softer material, which means a less wear and tear on the drill bits.

10 substrates included.
