UL Certification & Material Type

UL Certification & FR-4 Material Type

Material Type (TG Value)

The glass transition temperature (TG) determines the FR-4 board's ability to maintain structural integrity and electrical performance under elevated temperatures.

  • FR4-Standard TG 130-140: Suitable for most consumer electronics and general-purpose applications
  • FR4-TG 155: Required for higher temperature environments, automotive, and industrial applications. Mandatory for aerospace/medical 4 & 6-layer boards

UL Certification

PCB.UA holds UL certification with identification number E479892. UL (Underwriters Laboratories) certification ensures the PCB meets safety standards for flammability, electrical insulation, and material traceability.

UL Marking Options

  • No: No UL marking on the board
  • Yes (Any Location): Our engineers will determine a suitable location for the UL mark
  • Yes (Specify Location): You specify the exact UL mark location using our UL Marking Editor
