Packaging is the most negotiable part of a charger’s cost and the easiest place to make a product feel cheap. The decisions come in a clear order of impact.
The board grade decides whether the carton …
Most factory visits follow the same script: a meeting room, a walk along a line, a sample on a table. That format tells you very little, because every factory can produce a clean line for an hour. A useful audit …
Every charger bill of materials contains at least one part that is hard to replace: a specific GaN device, a controller IC, a transformer wound to a particular specification. When that part goes on allocation, a programme either has an …
A defect claim is not really a question about a product, it is a question about a production run: which components went into this unit, when was it built, what did the test data look like at the time. Factories …
A charger quotation that lists tooling as a cost but not as a duration is an incomplete quotation. For a new enclosure or a new plug mechanism, tooling is frequently the longest single item in the programme — and the …
A charger factory that says “we test everything” is describing one of three gates. The three gates do different jobs, and a programme that only has one of them is the programme that discovers problems at the port.
When two suppliers quote a 65W GaN charger at prices that differ by twenty per cent, the difference is almost never the power stage. It is in five places, and all five are visible in a properly itemised quotation.
Quotations come back vague for one reason: the request did not contain the details that change cost. A charger is a small product with a lot of cost drivers, and most of them sit outside the electronics.
A rejected production run is rarely a manufacturing failure. It is usually an approval that was given too early, on a unit that did not represent the final configuration. Four gates, in order, remove almost all of that risk.
Most buyers treat certification as paperwork that arrives with the shipment. In practice it is a project with its own critical path, and if it starts late it is the only thing standing between a finished production run and a …
