From Prototype to Production
Located in beautiful Southern Indiana, Friesen Design is a full prototype-capable shop. We can take your design from prototype to production.
We offer end-to-end electronics manufacturing services including PCB design, circuit board assembly, embedded firmware development, and precision CNC machining. Whether you need a single prototype or a low-to-mid volume production run, we have the equipment and expertise to deliver.
Our Capabilities
- PCB Assembly — Full SMT line with solder paste printing, pick-and-place, reflow, and selective soldering
- PCB Design — Schematic capture and board layout
- Embedded Programming — Firmware, drivers, and bootloaders in C
- CNC Milling — Precision machining on a Haas VF-2
PCB Assembly
We provide low-to-mid volume PCB assembly services with a complete SMT production line. From solder paste application through final assembly, every step is handled in-house.
Solder Paste Printing
DEK screen printer for accurate, repeatable solder paste application using precision stencils.
Pick-and-Place
Automated component placement for consistent, high-accuracy builds across all standard SMT package sizes.
Reflow Soldering
Heller 1088EXL reflow oven with precise thermal profiling for reliable solder joints.
Selective Soldering
KISS-103 selective soldering system for through-hole components and mixed-technology boards.
Assembled Boards
Completed assemblies ready for test and integration. We handle builds from prototype quantities through production runs.
PCB Design
We offer full PCB design services from schematic capture through board layout, ready for fabrication and assembly.
Design Capabilities
- Schematic capture and component selection
- Multi-layer PCB layout
- High-speed digital design
- Power supply and mixed-signal layouts
- Design for manufacturability (DFM) review
- BOM management and sourcing
- Gerber and fabrication file generation
We design boards that are built to be manufactured — because we assemble them ourselves. This tight feedback loop between design and production means fewer revisions and faster time to market.
Embedded Programming
We specialize in embedded C programming — the foundation of reliable, efficient firmware for microcontrollers and embedded systems.
Low-Level Drivers
Custom peripheral drivers for UART, SPI, I2C, ADC, timers, DMA, and GPIO. We write clean, well-documented driver layers that give you direct hardware control with a maintainable abstraction.
Bootloaders
Custom bootloader development for field-upgradable firmware. Support for UART, USB, and other transport protocols to enable secure, reliable firmware updates in deployed systems.
CNC Milling
Precision CNC machining services for prototypes, enclosures, fixtures, and custom mechanical parts.
Equipment
- Haas VF-2 vertical machining center
- 4th axis
Services
- Prototype and short-run machining
- Custom enclosures and parts
- Test fixtures and jigs
- CAD design available if needed — bring us a sketch or concept and we can model it up
Materials
- Aluminum, steel, plastics, and other common materials
