|
| Applications |
High Speed Digital PWBs (Telecom, Server, Mil-Aero)
- Replace surface mount bypass capacitors (their PTHs and costs), saving cost and board size
- Improve signal routing, especially in critical areas, lower PCB layer count
- Reduce simultaneous switching noise (SSN), lowering jitter and improved eye-openings
- Reduce EMI radiation from the edge of the board
- Reduce board thickness or increase Cu thickness for better power handling
|
Flip-Chip Packages
- Improved mid-range power delivery
- Reduced power supply noise by bringing the decoupling capacitors closer to the silicon die
RF Modules & Handheld/Cellphone motherboards
- Reduced module or board size
- Save cost by replacing surface mount capacitors
|
Military, Aerospace and Microwave
- Increased toughness and reliability with smaller, lighter PCBs
- SMT resistor replacement in Rigid and Rigid Flex designs
Memory (DRAM) Modules & Handheld/Cellphone motherboards
- Reduce module or board size
- Save cost by replacing surface mount resistors
High Speed Digital PWBs
- Termination for transmission lines lowers inductance and eliminates parasitics associated with surface mount resistors
