What happens inside the factory: tooling, inspection gates, capacity and quality control.
A cable assembly programme placed its order against a connector drawing and received an assembly whose overmould covered the connector's latch. The conductor, the gauge and the length were all correct; the tool had been cut before the latch position …
The counterintuitive part of an e-marker cable is that the chip carries no power. It carries a description, and the description is what allows the device at the other end to accept current it would otherwise refuse.…
Two cable programmes ordered the same length and the same connector, and one of them charged a laptop at the top tier while the other settled two levels below. The difference was not the length or the moulding; it was …
EVT, DVT and PVT look like three samples of the same thing, and they are not. The three builds are separated by the questions they answer, and a programme that runs them as three deliveries usually reaches the third one …
Three prototypes is the working number on a charger programme, and a brief that asks for one usually receives a unit that satisfies nobody. Twelve units are built at the first stage, three at the second and thirty at the …
A charger went to tooling with a two-piece enclosure and came back with a draft angle that could not be moulded at the wall thickness specified. The design was correct on paper; the two numbers had never been checked against …
Two brands briefed the same charger in the same quarter. One approved a working sample and released the tooling; the other ran the sample through a documented gate with a thermal measurement and a compliance review first. The second programme …
Nine hundred units per pallet is a comfortable figure for a charger carton, and the distance between nine hundred and seven hundred and fifty is a fifth of the freight on the same order. That figure is set by the …
The line that assembles fastest is rarely the one that ships the fewest returns; the test gate decides that. In a USB C charger programme the assembly benches can be multiplied with people, while the functional test station has a …
A branded USB C charger programme can open at 200 pieces per model - provided the protocol firmware, the port architecture and the cable specification were decided before the platform was chosen. Those three decisions define the product more than …
The order shipped on time and the first container sold well. The problem appeared in month four, when a batch began failing at a rate the brand could not explain, and the factory could not produce a record linking the …
Two sourcing trips were made in the same month with the same product brief. One came back with photographs, catalogues and five quotations; the other came back with a qualified supplier, a written capacity answer and a pilot plan. The …
