Why engineering teams choose BSU.
We asked our customers. Four things came up again and again in our customer interviews, and they're how we run every job.
We lean into the hard stuff.
- Complex, high-layer-count and mixed-technology boards that other shops turn away
- Custom test fixtures and jigs built in-house when a build needs them
- Broad capabilities, from conformal coating to rework, BGA re-ball and component removal and replacement
“No problem is too big or small for BSU... their engineers are an extension of our team”
30-year customer, safety-critical test equipment
Fast answers, fast builds, and easy to reach.
- Quotes for new builds in 3–5 business days
- 2–6 week typical delivery, with partial and rush options; 12–24 hour Rev A turns for established customers with boards in hand
- Reach us by text, phone, email, Teams or online
“[BSU] is almost always the first quote we get back, and [they] work with us, to improve sourcing timelines.”
Lead purchaser, 23-year client
The same inspection coverage on a prototype as on a production run.
- 5D X-ray, 3D AOI, SPI on every print and flying probe test, all upgraded in the last 18 months
- Built to IPC-A-610 and IPC J-STD-001, with Class 3 builds available
- A culture of asking for feedback and acting on it
“Few teams truly understand designs this complex... it was an easy decision to work with them on the next revision”
