Siemens Acquires DownStream
Technologies to Expand PCB
Design-to-Manufacturing Flow
Siemens Digital Industries Software
announced that it has completed the
acquisition of DownStream Technologies,
a leading provider of manufacturing data
preparation solutions for printed circuit
board (PCB) design. This acquisition
strengthens Siemens' PCB design
portfolio and expands its footprint in
the electronics small and medium-sized
business (SMB) market.
Designers Notebook: Layer
Stackup Planning for RF
Circuit Boards
When designing multiple layer circuits
requiring impedance control, the circuit
board designer will work closely with
an engineering specialist cognizant of
RF printed circuit
board design and
layout, including
mixed-signal
applications.
High-speed PCB design is complex enough, but
RF design can be a whole new ball game. RF
designers have to contend with tuning and other
ideas that traditional PCB designers don't have
to worry about, as well as crosstalk, parasitic
capacitance, and material limitations.
