Voltera Substrates (PCB) 3 X 4 FR 1 (10.16 X 7.62 cm)

• PCB board without glass fibers
• Size 3 x 4 FR 4 (10.16 x 7.62 cm)

The Voltera Substrates (PCB) 3 X 4 FR 1 (10.16 X 7.62 cm) are made of epoxy laminate, which is flame retardant and reinforced with glass fibers. If you need to drill holes, we recommend using the FR1 substrate as it does not contain glass fibers, which can be hazardous to your lungs. Additionally, the material is softer, which reduces the wear on the drill.
