Prototype Assembly & Bring-Up
SiGenix assembles and brings up prototype boards in-house — from low-volume SMT assembly to manual fine-pitch soldering and BGA rework. Because the same engineers who designed the board do the bring-up, debug cycles are fast and nothing gets lost in translation between design and hardware.
Hands-On Assembly and First-Article Debug
The first article of a new board is where designs meet reality. We assemble prototypes in-house so the design team can power up the first unit hours after parts arrive — checking supply rails, current draw, clocks, and communication buses methodically before committing to a full build.
When something is wrong — and on a first article, something usually is — having the designers at the bench matters. We debug with oscilloscopes, logic analyzers, JTAG, and thermal imaging, find root causes instead of symptoms, and fold every finding back into the design before production.
What Our Prototype Services Include
SMT & Through-Hole Assembly
Low-volume surface mount and through-hole prototype assembly in-house, so first articles are built by people who understand the design intent.
Fine-Pitch BGA & QFN Rework
Manual fine-pitch soldering and rework of BGA and QFN packages — replacing suspect parts and recovering boards without scrapping the build.
First-Article Bring-Up
Methodical power-up of new hardware — supply sequencing, rail voltages, current draw, clocks, and resets verified before firmware ever runs.
Bench Debug & Instrumentation
Root-cause debugging with oscilloscopes, logic analyzers, and JTAG — tracking down signal integrity issues, marginal timing, and intermittent faults.
Power Sequencing & Current Profiling
Verification of power supply sequencing and detailed current profiling — critical for battery-powered designs and multi-rail processors.
Thermal Imaging & Stress Testing
Thermal imaging to find hot spots and stress testing to expose marginal designs before they become field failures.
Frequently Asked Questions
Why assemble prototypes in-house instead of using an assembly house?
Speed and insight. The design team can build and power up a first article within hours of parts arriving, and any problem found at the bench goes straight back into the design — no communication gap between the assembler and the designer.
Can you rework BGA and QFN packages?
Yes. We do fine-pitch manual soldering and rework of BGA and QFN parts in-house, which lets us swap suspect components and recover prototype boards instead of scrapping them.
Can you debug a board you didn’t design?
Yes. We bring up and debug third-party hardware regularly — using oscilloscopes, logic analyzers, JTAG, and thermal imaging to find root causes in boards that don’t power up, behave intermittently, or fail in the field.
Do you handle production volumes?
Our in-house assembly is focused on prototypes and low volumes. For production, we prepare complete fabrication and assembly documentation and support the handoff to your contract manufacturer.
Have a board that needs building — or isn't working?
Whether it's a fresh design ready for first article or a prototype that won't power up, tell us what you're working with and we'll tell you honestly how we can help.
