What is Contract Manufacturing? Contract manufacturing is an arrangement in which a company (the client) outsources the production of its products or components to another company (the contract manufacturer). The contract manufacturer is responsible for producing the goods according to the client’s specifications, while the client retains control over the design, intellectual property, and distribution…

What is ENIG? ENIG is a chemical process that deposits a thin layer of nickel and gold onto the copper pads and traces of a PCB. The process involves several steps: Cleaning: The PCB is thoroughly cleaned to remove any contaminants or oxidation. Microetching: The copper surface is slightly etched to improve adhesion. Electroless nickel…
