Sponsored content by CMLStrategic solutions to the current material shortage in the PCB industry In the past few month’s PCB laminates and base material costs have seen a dramatic rise. The natural consequences of this inflation besides the higher production costs are the unavailability of certain materials paired with longer delivery lead times. A problem like this will destabilize any supply chain, or that’s what you may think.

Using A2B for Audio-Conferencing Systems One of the main hurdles in audio installation in a modern conference room these days is the need to interconnect a variety of input/output transducers into the main audio console. This is usually done using individual point-to-point shielded cables for each node, which is bulky and still requires separated external power supplies on each of them.
