Most OEM charger projects do not fail because a stage takes too long. They fail because two stages run in the wrong order: artwork is approved before the enclosure is frozen, or certification is booked before a worst-case build exists. …
A trial report lands in your inbox with a dimensional table, a set of photographs and a list of corrections, and someone asks whether the tool can be approved. Reading it well is a skill, and it decides whether the …
A defect claim goes out and a three-page document comes back with a photograph, a cause and a promise to be more careful. It looks like an 8D. It is not. The difference between a real 8D and a courtesy …
An inspection report comes back with a reject quantity, and the next message asks a commercial question disguised as a technical one: can the batch be reworked? The answer depends on the defect, not on the schedule, and the decision …
An inspection report arrives with a sample size, an accept number, a reject number and a conclusion. If the accept and reject columns look like a lottery table, this is the guide that turns them into a decision: ship, hold, …
Freight is quoted per container, but it is paid per unit. Ten millimetres off a master carton can move the number of units per container by a few percent, and across a season that difference is a real line in …
Packaging is the part of a charger programme where design ambition meets freight arithmetic. A retail box that looks premium on a shelf can add cost and volume in ways that are invisible in the unit price and obvious in …
An audit is not a tour. A factory that assembles chargers can look impressive and still be unable to show a batch record, a calibration certificate or a process instruction. The purpose of the visit is to verify that the …
A component goes on allocation, the factory offers an alternative, and the question arrives: does this need retesting? The answer depends on whether the alternate was qualified in advance or introduced under pressure. A policy exists to make that decision …
Traceability is not a label on a carton. It is a link between four records that most factories hold in four places: the unit or lot, the components that went into it, the test result it produced, and the shift …
The quotation states a unit price, a minimum quantity and sometimes a delivery term. It rarely states the calendar that starts when the mechanical design is released. That calendar - not the production line - is what determines when a …
A single final inspection can only reject defects that are visible or measurable at the end of the line. By then the cause - a wrong component, a cold solder joint, a mis-set fixture - has already been repeated across …
