Design Features<\/h4>\n\n\n\n

We started out from designing circuit boards.
Using technology cultivated over many years of experience, we handle approximately 800 high-quality circuit board designs per year.
By working in cooperation with our in-house circuit board manufacturing and mounting factories, we are able to offer designs that make use of our know-how in circuit board manufacturing and mounting.
We have an extensive track record of designing in a wide range of genres-from high-speed digital signal processing for image processing, in-vehicle equipment, and laptops to high-voltage devices such as inverter devices.<\/p>\n<\/div>\n\n\n\n

simulation<\/h3>\n\n\n\n

We use simulation to solve problems related to SI (signal quality), PI (power quality), EMC, and heat.
By performing simulation in parallel with the board design, we can shorten the time required for simulation and reduce the risk of having to redesign.<\/p>\n\n\n\n

SI analysis<\/h3>\n\n\n\n

From a few megahertz to orders of gigahertz or more, we analyze and optimize signal waveforms and losses at the board design stage and reflect this in the design data.<\/p>\n\n\n

EMC analysis<\/h3>\n\n\n\n

It is possible to perform frequency (resonance) analysis of PCB planes, which have a significant effect on EMI, and EMS (susceptibility) analysis, as well as EMI near-field\/far-field radiation analysis using an electromagnetic field solver.<\/p>\n\n\n

Thermal analysis<\/h3>\n\n\n\n

We propose various heat countermeasures based on the results of analysis ranging from simple analysis by upstream thermal design (PCB equivalent thermal conductivity \/ thermal network method \/ device surface temperature calculation) to thermal fluid simulation.<\/p>\n\n\n
