In-house printed circuit board and antenna manufacturing
Rapid prototyping of high-frequency, high-power PCBs and antennas is often hindered by the cost and lead times associated with outsourcing. This research explores the feasibility of transitioning to in-house fabrication using benchtop PCB milling technology. To assess the viability of this approach, we fabricated a series of test PCBs and antennas using an LPKF ProtoMat S104 benchtop mill. Preliminary CST simulations, validated by practical measurements of the fabricated components, indicate that the achievable manufacturing precision is sufficient for high-frequency performance. Additionally, high-power testing will be conducted to evaluate the power handling capabilities of these in-house manufactured components under realistic operating conditions. This presentation will delve into the specific capabilities and limitations of in-house PCB milling, directly comparing the performance, cost, and lead times to commercially produced components. The findings aim to demonstrate the potential of in-house fabrication for significantly reducing prototyping costs and lead times, ultimately accelerating the development cycle for high-frequency, high-power, custom components.
