I am a Hardware engineer and Firmware & App developer.

I have worked extremely successfully together with my clients for the past 7+ years.

In the meantime, I have been experienced the following fields of circuit and PCB and Manufacture :

– analog circuit and PCB design

– digital circuit and PCB design

– mixed analog and digital circuit and PCB Design

– high speed signal circuit and PCB design(25Gbps, 20Gbps, 12Gbps, 8Gbps, 4Gbps, 2Gbps)

– wireless device and home automation system(GPS, GSM, Bluetooth, Wi-Fi, Z-Wave, Zigbee, LoRa, RFID, LTE)

– sensor signal processing(PPG, SPO2, ECG, CO2, Gyroscope)

– various memory interface(Nand flash, NOR flash, EPROM, EEPROM, Flash ROM, NVRAM, SRAM, SDRAM, DDR, DDR2, DDR3, DDR4)

– various signal processing(PCIe, SATA, HDMI, Ethernet, USB, SD Card, SPI, UART, USART, I2C, CANBUS, VGA, etc)

– Simulation by using ANSOFT tools(Designer, HFSS, Q3D, SIwave) and Mentor graphics tool(hyperlynx)

– SI, PI, EMI, EMC, ESD Stable Design Technology

– a reliable DRC check and DFM check process by using Mentor graphics tool(Xpedition Enterprise (X-ENTPVX.1.1))

– any shaped Rigid board, Rigid-Flexible board and Flexible board design and manufacture

– 2~44 layers printed circuit board design and manufacture

– assembled from 0402 SMD type to 4094 pins BGA type

The most recent successful project is SuperComputer Main Board Design(reached the speed of 148petaflops and the minimum power consumption system).

Now I’m looking for more clients who can use my technology.

I will do my best for clients who is interested in me.

I will service on real-time for my clients.
