Outdoor radar and microwave equipment can see humidity, temperature swings, and repeated handling before a board reaches final system test. For a PTFE-based laminate, the project risk is not only RF loss; it is whether the finished RO5880 PCB keeps its layer registration, connector datum, and antenna geometry through the approved process. This RO5880 PCB...
Ka-band front ends often use grounded coplanar waveguide (GCPW) because the signal and return path can stay on one layer near a connector or active device. The challenge is holding the gap, via-fence geometry, solder-mask opening, and reference plane together after fabrication. This guide shows how an RO5880 PCB GCPW release can address those engineering...
An RF design can pass simulation and still lose yield during assembly when solder-mask openings, land patterns, or shield clearances are not matched to the PCB stackup. This article explains how a controlled RO4003C PCB assembly package reduces those handoff risks for compact 5G and microwave modules. Why assembly DFM matters for an RO4003C PCB...
An RF power board can pass an electrical review and still fail in the field when heat changes the laminate geometry, connector datum, or solder-joint stress. This engineering guide treats the RO4350B PCB as a thermal and RF structure for high-power modules. The values below are planning guidance based on vendor-typical material behavior and KKPCB...
Engineering intent. A 77 GHz radar front end is sensitive to the geometry between the antenna elements, feed transitions, and transceiver. This article explains how to plan a RO3003 PCB stackup for that path. It is a conceptual design workflow, not a customer case study or a measured production result. RO3003 is a ceramic-filled PTFE...
A GNSS module PCB is often treated as a simple carrier for a receiver module, antenna connector, and power supply. That view misses the part of the board that most often determines whether the receiver sees a usable signal: the path from the antenna to the module input. The layout must preserve the intended transmission-line...
What is a High Current PCB? A High Current PCB is a printed circuit board specifically engineered to carry significant electrical current—ranging from several amperes to hundreds of amperes—without excessive heat generation, voltage drop, or reliability issues. Unlike standard PCBs, high current designs must address resistive losses (I²R), thermal buildup, and mechanical stress. If not...
