Most manufacturing websites say they can do everything. That is not useful to you: if a supplier claims to fit every project, you have no way to tell whether they fit yours.
So here is the honest version. The right-hand column loses us enquiries on purpose — and the projects in the left-hand column are the ones where we are genuinely the better choice.
There is a commercial reason too. A supplier who says "yes" to everything tells you nothing about where their strength actually is. A supplier who tells you where they are weak is one you can believe when they tell you where they are strong.
You need certified-quality PCB or PCBA — no minimum order, from 1 piece up to 500,000-piece runs — and want fabrication, component sourcing and assembly handled by one supplier.
You need millions of units at rock-bottom unit price, or manufacturing inside your own country.
Still deciding whether to use one supplier or three? Turnkey vs. split suppliers → works through the cost of each, including the parts that never show up on a quote.
