Security is keyin the electronics industry. It is vital that users can rely on the finished product when considering factors such as fireand electrical safety, which means that both the PCB and the materials theycontain must measure up to the highest standards. To ensure that the boards doconform, it has become common practice to UL certify the constituent materialsor the PCB itself.
To start with, what is UL? The letters UL stand for Underwriters Laboratories.
Why is UL recognition important? UL is a major authority and enjoys a good reputation in the PCB industry. The company is irreplaceable for testing fire and electrical safety. Customers from around the world – including well-known Chinese companies – demand factories that can achieve UL recognition. Having UL recognition is therefore very important for PCB factories to produce secure boards and be able to access the international market.
