What is RoHS?

RoHS regulations are designed to limit or eliminate substances that are dangerous to the environment and to people. Inadequately treated e-waste poses environmental and health risks. The RoHS directive is also meant to increase the amount of e-waste that is appropriately treated and to reduce the volume that goes to disposal.

RoHS (Restriction of Use of Hazardous Substances) regulations limit specific substances – lead, cadmium, polybrominated biphenyl (PBB), mercury, hexavalent chromium, and polybrominated diphenyl ether (PBDE) flame retardants – in electrical and electronic equipment.

Does RoHS affect the quality of PCBs?

RoHS is not a quality standard, and the simple fact that boards are RoHS compatible does not add to the quality of the board. RoHS, or more familiar ‘lead-free’ does have serious effect on PCB fabrication and soldering. The fact that boards are soldered at higher temperatures requires changes in the PCB manufacturing process. New FR-4 materials are developed to withstand the higher temperatures without reducing the lifetime of the final product.

What is the Underwriters Laboratory (UL)?

UL is the certifying agency for product safety in the United States of America. The Underwriters Laboratories (UL) test products worldwide according to corresponding U.S. product safety requirements, so that these products may be marketed and sold in every part of the United States of America.

How to add UL marking on the PCB?

We have 2 active board classes, each with its own UL marking:

GLinkPCB's UL identification number is E479895

If you want your board marked with the Underwriters Laboratory logo, please specify on the order form or tell our sales staff.. Please note the UL logo should be added to the silkscreen layer of the original Gerber file.
