Shengyi Technology Obtains UL Listing for FR-4 Grade S1190M

Reading time ( words)

Shengyi Technology Company Ltd. is pleased to announce that their FR-4 product, S1190M, has been listed by UL with an electrical and mechanical Relative Thermal Index (RTI) of 150°C. Recently UL changed the definition of FR-4 to allow already listed FR-4.0 and FR-4.1 to be used in PWBs operating up to 150°C if the Long Term Thermal Aging (LTTA) data passed the electrical and mechanical requirements.  

Shengyi is the first base material supplier world-wide to have a FR-15.0 product listed with an electrical and mechanical Relative Thermal Index (RTI) of 150°C. That product, S1190M, is a brominated epoxy system with a Tg of 200°C and a Td of 355°C designed for lead-free processing. S1170G was the first halogen-free product to be listed as FR-15.1 with a Tg and Td of 180°C and 390°C respectively. Both products exhibit high thermal reliability and excellent CAF resistance which allows them to be used for communication, computer and automotive applications.

S1190M products are listed in Shengyi’s UL File # E109769 as an ANSI Grade FR-15.0. FR-15.0 indicates that it is a brominated FR-4 product with an RTI of 150°C.

Board designers can feel more comfortable knowing that S1190M can be used at higher temperatures than for traditional FR-4s. Other current FR-4 products will also be listed as FR-15 in the Shengyi UL file as customer requirements dictate.
