Board Design
We provide concurrent PCB design solution that integrate electrical and thermal fluid/stress simulations for customer's product developments.
Design PCBs with low warpages
Examples of PCB stress-strain analysis
We perform warpage analysis, using Cu ratio model based on the real PCB designs. We propose optimized PCB designs low warpages whether BGAs are used.
We optimize parts layout and trace pattern in terms of warpage reduction.
Design PCBs with joule heat analysis for high current applications
We propose optimal PCB designs with thermal analysis that integrate joule heat and device operating heat analysis.
1) Perform joule heat analysis with precise trace pattern modeling based on the real designs.
2) Improve trace flexibility with Embedded Bus Bar
3) Place control logic and power devices on the same surface layer.
Realize stable operation for high performance PCBs
Our optimized PCB design solutions for high performance applications reduce prototype cycles, lead-time, and cost.
1) Propose suitable PCB specifications
Optimum materials, Layer structure and design rules
2) Signal Integrity(SI)Analysis
Waveform quality and timing of high-speed DDRx interface.
3) Power Integrity(PI)Analysis
Check DC Drop and Input Impedance of Power Line for Digital Board.
4) VG plane resonance analysis
Check VG plane resonance for Digital Board.
Reduce layer-count and electrical parts to satisfy the electrical performance.
1) Design Review
Minimize line width and Via diameter within target impedance(Z0) to increase routing channels.
2) Layout Review
Increase routing channels by replacing to smaller parts and displacing dumping registers.
3) Validation with simulation
Validate electrical performance by implementing transmission waveform simulation.
Layer count reduction with the compatible electrical performance and displacements of dumping registers enable cost-down of PCBs and PCBAs.
Design cycles reduction
Concurrent PCB designs with multiple users reduce design cycles by half, minimizing the prototype development lead-time for customers.
FUJITSU INTERCONNECT TECHNOLOGIES helps customers solve the design issues.
We provide comprehensive design solutions for performance, miniaturization, and cooling in a wide range of products, devices and modules.
