Run each customer’s product from new-product introduction to box build and shipment.

An EMS provider builds other companies’ products. Each customer brings its own BOM, its own forecast and its own idea of a good test report. One customer’s engineering change order (ECO) must never reach the SMT line that is building for another.

Management software for contract electronics keeps every customer’s product, revision and forecast apart while the floor runs shared pick-and-place lines. A first session traces one product from its ECO to the serial-numbered unit on a pallet, and it marks the step where today’s record breaks.

A new customer’s first order lands together with Gerber files and a bill of materials. Engineering runs a design-for-manufacturability review and plans a pilot build. Purchasing quotes components and flags long-lead or single-source parts, such as a specific FPGA or a custom transformer. A rolling forecast follows. Then firm purchase orders arrive.

Production prints solder paste, places components, reflows boards, wires harnesses and integrates the result into an enclosure with a display, a power supply and a rating label. Firmware is flashed. Each unit passes an in-circuit or functional fixture and receives a serial number. When a customer swaps a part, the change must reach purchasing, the component store and the line on the same day, or the wrong connector ends up in a hundred units. Finished goods ship by customer. RMA returns come back later.
