The 6700 series features a harder durometer (85 Shore A), which can also be useful anywhere a harder Bumpon product is needed. The R25 adhesive provides excellent adhesion to printed circuit boards and a variety of chassis materials. 3M features a variety of shape dimensions to accommodate the space available on the chassis/PCB and the soldered joints, as well as to give the correct Full Text . . .
This extremely popular cylindrical shape provides design flexibility over mechanical spacers. Designers can place the spacer as needed after the board is assembled and no drilling is required.
The A3 is another highly popular and versatile shape. Slightly smaller in height, the A3 spacer prevent boards from bending and breaking, saving material cost and lost productivity and increasing profits.
The high performance, synthetic rubber adhesive offers excellent initial and ultimate adhesion to a variety of surfaces including plastics, FR4 and various metal surfaces. The taller height is ideal for providing correct spacing between multi-stack boards
