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 …
A customer reports that three units failed in the same week. If the factory can identify the batch, the component lots and the test records within a day, the investigation is technical. If it cannot, the investigation becomes a discussion …
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 …
Two quotations arrive for what looks like the same 65W charger, and the unit prices differ by more than the components cost. The gap is usually not margin. It is the amortisation of tooling, the packaging route, the branding level …
The first reply to most charger enquiries is a price range, because the enquiry did not contain enough information to price. An RFQ that states the device list, the markets, the branding level and the quantity usually comes back as …
A bulk shipment is rejected because the logo is the wrong shade, the cable is a lower rating than the sample, or the box insert changed. None of those defects appeared at the last inspection; they appeared because approval was …
Certification is usually treated as a document order placed at the end of a project. It behaves much better as a project with its own scope, samples and critical path, run in parallel with tooling and packaging. The plan below …
A charger can be built to the right standard and still fail a customs check or a retail compliance review because the paperwork does not match the product. The EU and the US approach this differently, and the brand that …
Selling the same charger in the EU, the UK, the US and Australia usually starts as a product question and becomes an inventory question. Three approaches are common, and the right one depends on how many SKUs your channel can …
Wattage is usually chosen by looking at what competitors sell. The more reliable method is to start from the devices your customers actually charge, because that determines the band, the port count and the protocol - and, eventually, which SKUs …
You are finalising a charger range and two quotations land on your desk: the same 65W output, two different bills of materials, one roughly a size smaller than the other. The gap is the power semiconductor. This article is about …
