软性FPCB板有UL认证如何进行标识？

各位高手，供应商提供的软性FPCB板有UL认证证书，但要不要在产品进行标识？
一般PCB是有UL标识及档案号的，但软性FPCB如何标识呢？请各位指点下，先谢了！

Depends on the description shown in its UL FUS procedure, you can ask your PCB vendor to provide the marking requirement of UL, then you can clearly know how to mark it...

7.1.1 Where there is sufficient space as defined in 7.1.2, each FMIC shall be plainly and permanently
marked, such as by etching, printing, solder mask marking, or nonconductive ink printing or screening,
with the manufacturer’s name, trademark, or authorized initials or symbols by which the organization
responsible for the FMIC shall be identified, followed by a Type designation, or code number or equivalent
designation to indicate the FMIC has been tested for flammability, and where applicable, a combination of
bond strength, conductive paste adhesion, plating adhesion, cover material, (ambient) bend, cold-bend,
and repeated flexing. Conductive markings, such as etched copper, shall be considered as electrical
elements (unconnected conductive part) of the circuit and shall not reduce the electrical spacing
requirements for the end product.

7.1.2 Sufficient space is defined as a space at least 2.5 mm (0.1 inch) high and of sufficient length to

accommodate the marking. When there is insufficient space to accommodate the marking, the marking

shall be marked on the smallest unit container. The marking may be marked on the panel frame to which

the FMIC is attached, if the FMIC will remain in the panel construction when shipped to the OEM.

7.1.2很关键。
