Microwave PCB Manufacturing
Radio Frequency (RF) and Microwave PCBs are PCBs created to transmit signals in higher frequency ranges - megahertz to gigahertz frequency ranges (medium to extremely high frequency). Hence, RF PCBs are used in devices that transmit high frequency communication signals like military radars and cellphones. Twisted Traces is one of the well-known manufacturers of demanding microwave PCBs in the US. We provide customized solutions to our clients in various challenging markets such as military, aerospace, and telecommunications.

Special Assembly and Testing Equipment
Most standard microwave PCBs are assembled using standard fabrication equipment. However, we have invested in specialized equipment, which helps us meet the requirements of demanding PCBs. We have invested in advanced Thru-hole assembly equipment, which helps us ensure high quality through hole PCBs. The following are some of the other special assembly and testing equipment in our facility.
- RF assembly of surface mount components, connectors, drop-in cavity components
- Advanced RF test centers with network analyzers in the range of 50 MHz to 40 GHz
- Laser Direct Imaging (LDI) equipment that helps hold very fine trace widths, as well as meet front to back registration requirements.
