The Situation
Westermo's R&D division is constantly working to move the boundries of what is technically possible for industrial date communication equipment. While it is important to be at the forefront of technology development, it is also crucial to ensure highest quality at all levels.
Their products are smaller then any of their competitors and therefore they use High Density Interconnect PCB boards, using micro-via's and lots of layers. This means there is limited space for their Power rails. The low voltage CPU's draw large current and they need to guarantee the voltage requirements at the Pin.
