Backplane PCBs
Backplane PCBs are the gateway to higher technology applications.
Benefits include elimination of "jumper" cabling with larger sized backplanes hence improving reliability, lower assembly cost and stronger signal integrity.
In addition, their copper weight variability can carry high speed signals or power with ease. They also allow for a wide range of material selections to suit the design from power to high speed (100Gbp) applications.
A wide range of materials for high speed circuit boards are offered to clients. The differences based on material selection can be very large. Material selection depends on not only loss factors, but one must take account of all of the properties to make an optimal choice of material. The price/performance ratio may also vary widely.
As industry demand for these boards increase, our team at Sourceman, continue to provide our clients with unparalleled support as required with the fastest industry turn around times.
