CTI in PCB Materials: Beyond FR-4 Selection
In PCB design and manufacturing, engineers usually focus on impedance control, thermal performance, stackup structure, and signal integrity. However, the base material itself determines another

High-speed PCB design becomes necessary when the PCB interconnect starts to affect the voltage or timing seen by the receiver. There is no single clock-frequency

Lead-free HASL is usually the better starting point when cost matters and your assembly can tolerate some variation in pad height. ENIG becomes more useful

PCB manufacturing converts released design data into a tested bare circuit board through a controlled sequence of material transformation and verification steps. Each stage changes

PCB cost cannot be reduced to one reliable price per board, layer, or square inch. A bare-board quote depends on how the design uses a

PCB fiducials are exposed copper reference marks used by SMT equipment to align the real board or panel with programmed CAD coordinates. Stencil printers and
