Answers to “what does it mean that …”

What is UL?

The Underwriters Laboratory (UL) was set up around 120 years ago in the USA as an independent facility to test the safety of new products and new technologies. Today it has a network of sites around the world focused on product safety. It test products, certifies manufacturers, and produces and updates safety standards across a broad range of industrial and commercial sectors. More.

For PCB’s the main standards are UL 796, the specific PCB standard, and UL 94 for flammability testing of all plastics. These specify a number of performance tests to measure the long-term reliability and fire safety of the PCB. If a board is released to these standards, it is marked with the UL logo, the fabricator’s logo and the board type.

For more information please see What About UL? on the Eurocircuits website.

What does the EMS partner network stands for?

EMS stands for Electronic Manufacturing Services and is a term used for companies that design, manufacture, test, distribute and provide return/repair services for electronic Industry.

We have developed and expanded our EMS Partner Network to provide addition services to our customers.

Annular Ring (OAR & IAR)

The Annular Ring value is defined as the amount of Copper from the edge of the Drilled Hole to the Copper Pad associated with the hole.

OAR – Outer Layer Annular Ring – for more information click here.

IAR – Inner Layer Annular Ring – for more information click here.

Also see our PCB Design Guidelines section on Holes.

Outer/Inner layer copper foil? Start and Final copper thickness?

Copper foil is the starting thickness of the copper of any given layer of the PCB, choosing the correct thickness depends on the design and may be different for Inner and Outer layers on the PCB.

Please see our PCB Design Guidelines Classification section for more information.
