Reading time ( words)

Shengyi Technology Co. Ltd. is pleased to announce that their Songshan Lake Industrial Zone, China facility has been approved as an official authorized UL laboratory. Shengyi Technology is the third laboratory to earn this honor worldwide. The authorization is for both Long Term Thermal Aging (LTTA) and UL-94 Flammability testing both of which are most important safety indexes. This authorization allows Shengyi to conduct LTTA and Flame testing for products in-house as well as for third party producers of base materials for the electronics industry.

The application was made over three years ago to UL and Shengyi purchased the necessary conditioning and test instrumentation for the program. UL technical personnel visited Shengyi a number of times to conduct the required training for sample preparation, test equipment calibration/verification, and analytical test procedures. After a number of programs to establish correlation between Shengyi Technology and UL Taiwan were completed, UL agreed to finalize the CTDP authorization. 

On 11 May 2017, the Vice-President of UL, XiuKun Yu, and the UL Sales Manager of South China, Lance Liu, along with Jessica Liu visited Shengyi to present the authorization certificate. RenXi Chen, Shengyi General Manager, Yaode Zeng, Shengyi Chief Engineer, and QianFa Liu, Deputy Director of China National Engineering Research Center of Electric Circuit Base Materials accepted the authorization documents at a ceremony at Songshan Lake.

CES 2018: Disruptive Technologies and Fun PC Stuff

01/24/2018 | Dan Feinberg, FeinLine Associates, Inc.
Two disruptive technologies that we have been covering for the last few years are 3D printing—especially as it pertains to PCB fab—and autonomous driving. 3D printing has been around for a few years, but it seems like 3D printers were introduced to CES very recently. This year there were almost 50 exhibitors showing their latest offerings. Most of them were in the LVCC in the north hall at the 3D Printing Marketplace.
