ISU Petasys Buyer Map

Don | ISU Petasys | October 2026

As of 15 Oct 2026

ISU Petasys builds ultra-multilayer circuit boards for network equipment, servers and storage, high-performance computing, AI accelerators, chip testing and aerospace.

This page maps the kinds of organizations in the United States that buy boards like these, who usually signs off at each, and where a first conversation tends to open.

Where the buyers sit

Groups drawn from the product lines ISU Petasys publishes. A group with a clean public count shows it banded; the rest say so.

US firm counts by industry code, banded deliberately.

Network equipment makers

Router, switch and backplane boards are the core ISU Petasys line. At these companies the board supplier is usually settled by engineering and supply chain together.

RoleWhat they answer forWhere ISU Petasys fits
Director of Hardware EngineeringBoard designs for routers, switches and line cards, and which fabricators can build themRouter, switch and backplane boards at high layer counts
Signal Integrity or PCB Design LeadStack-up, materials and loss at high data ratesStack-up and material choices for boards of many layers
Commodity Manager for circuit boardsQualified board suppliers, cost and lead timeA qualified source for the hardest boards to build
Director of Supply ChainSupplier risk and second sourcesA second source for high-layer boards

Server, storage and AI hardware makers

Denser servers and accelerator modules are pushing layer counts up, which narrows the list of fabricators a hardware team can use.

RoleWhat they answer forWhere ISU Petasys fits
VP of Hardware EngineeringSystem boards for servers, storage and acceleratorsServer, storage and AI accelerator boards
Hardware Engineering ManagerBoard bring-up, yields and design changesBuilds of high-layer system and module boards
New Product Introduction ManagerMoving a design from prototype to volumePrototype through production on the same board
Commodity Manager for circuit boardsBoard cost, capacity and lead timeCapacity for high-layer boards

Chipmakers and test equipment makers

ISU Petasys lists boards for chip testing, which are bought by the teams that test and sort parts rather than the teams that design products.

RoleWhat they answer forWhere ISU Petasys fits
Director of Test EngineeringHow parts are tested and sorted, and test costLoad boards, probe card boards and burn-in boards
Test Hardware EngineerInterface boards between the tester and the deviceLoad board and probe card board builds
Purchasing ManagerSuppliers and lead times for test hardwareA source for high-layer test boards

Aerospace and defense electronics makers

Boards in these systems are held to long-life reliability standards, so a supplier earns its place through the quality system before the price.

RoleWhat they answer forWhere ISU Petasys fits
Director of Electronics EngineeringReliability of the boards inside a system over its lifeHigh-reliability boards for aerospace use
Supplier Quality ManagerCertified suppliers and auditsAn aerospace and defense quality certification
Procurement or Subcontracts ManagerApproved sources, cost and scheduleA certified source for high-layer boards

Cloud operators and the hardware they design

Some large cloud and data center operators design their own switches and servers. There the hardware engineering lead and a sourcing manager often qualify the board supplier alongside the contract manufacturer that assembles the system.

These teams are few, and there is no clean public count for them. The groups above are where a steady run of first conversations is more likely.

Ten people to start with

Where to start

Start with the design team, not purchasing

For boards at the highest layer counts, the fabricator is usually settled while the design is still open, on stack-up, materials and loss. A short note to a hardware or signal integrity lead with a live high-speed design reaches the decision before it goes out to quote.

Lead with accelerator and server boards

ISU Petasys names AI accelerator boards as a newer line beside its server and storage boards. Hardware teams at accelerator and server makers moving to denser boards are the clearest new first conversation, opened with the VP of Hardware Engineering.

Use test boards and aerospace quality as a side door

Test engineering leads at chipmakers and supplier quality managers at avionics makers buy on proven reliability. A note naming the test board types or the aerospace quality certification fits how ISU Petasys already describes those lines.

Built from public federal registries and public information about ISU Petasys, counts banded deliberately.
