We have worked on many projects, and have decided to give you an idea of the process we go through to finalize a project.
The Digital WER Test card that we have designed is a highly complex, wide function card, which:
- is a test card for an IC maker
- is an 8 layer board, with controlled impedance
- contains almost 1000 components including FPGA
Such a project takes long time to design and finalize. This is how long each step of the project took us:
- Schematic design: 3 weeks (with multiple iterations and reviews)
- PCB layout: 2 weeks
- PCB fabrication: 1 week
- PCB assmelby: 1 week
- First article Bring-up: 1 week
- The Initial FPGA load (verilog) (done during bring-up): 1 week
- After the initial run, there were 3 more production runs.
Our customer received:
- Schematic diagram
- Bill of materials
- Gerber files
- Fabrication drawing
- Assembly files
- Assemlby drawings
- First working board and programming instructions
- Bit file for FPGA and the verilog source code
Similar to Actuator Driver but has 192 output channels
Layout, mechanical design and enclosure design. Multiple iterations between this plug-in module and motherboard, schematic, mechanical and layout in order to fit everything. For PCB RF material Rogers 4004 has been used to allow operation up to 6GHz. Enclosure - milled 6061-T6 aluminum. Design time - 2 weeks.
Some features of this project:
- 96 independent output channels.
- Single 12VDC power input.
- onboard 300VDC power supply.
- 0-300VDC output for each channel with 12 bit resolution and current limiting feature.
- USB connection to a PC.
- PCB - 4 layers.
Design time - 6 weeks, including PCB manufacturing and shipping.
