SMT(SMD) Grounding Gasket (SMTG Series)

Product Name : SMT(SMD) Grounding Gasket_SMTG Series

Product Description

With consumer electronics products adds more functionality and the design of the smaller and thinner form factor, PCB Layout complexity is increasing, it may be more interference with the function of electronic products. Electronic engineers design space becomes more challenging. These challenges require additional ground to help eliminate noise, ESD, EMI, RFI and other related phenomena. The Newest SMD grounding pad (SMT Gasket) (SMTG Series) of Metal Alloy film cover silicone rubber. This product also provides excellent electrical characteristics and compression rate. Also, there are many different sizes for customers to choose.

Solderability test (Pulling Force ≧ 2kgf )
Soldering the SMT Gasket to the printed circuit board and passed Re-flow after. The board is fixed at a speed of 50mm per minute and generates tension from the upper side. When the SMT Gasket is completely separated from the printed circuit board,
the pull value is calculated.
