Samtec's Signal Integrity E-mail Tips:

• (December, 2007) When do I need a High Speed Connector?

The question "When do I need to use a high speed connector?" often arises. Unfortunately, with each application, the answer will vary. One rule of thumb is based on the signal edge rate or rise time. Rise time is generally defined as the amount of time it takes for a signal to switch from one logic state to another. With rise times faster than about 1ns, many interconnects become a critical portion of the transmission path, and further analysis is often required.

Samtec's Flex Circuitry E-mail Tips:

• (October, 2007) Can I put mixed interconnect style components on a single layer flex and have the components all on the same side?

  Yes, by using various methods to generate apertures in the dielectric materials, mixed technology components can be populated on teh same side of the flex. However, through-hole solder pads are usually on the opposite side from surface mount pads if you want to keep all components on one side.
