Black Disk Phenomenon in ENIG Process: Causes and Solutions
Jun 24,2025
1. What is the black disk phenomenon in ENIG process? ENIG (electroless nickel immersion gold) is one of the mainstream processes for PCB surface treatment. Its "black disk phenomenon" refers to the abnormality of the nickel layer or gold layer on the surface of the pad due to chemical or electrochemical reactions, resulting in the pad appearing abnormally black or dark (usually the nickel layer c...

Detailed Explanation of OEM and ODM Models in The PCB Industry
Jun 11,2025
1. Basic Concepts OEM (Original Equipment Manufacturing) OEM means that the customer completes the PCB design by himself, and the factory produces it according to the design drawings. The customer controls the design process, and the factory is responsible for manufacturing. For example, the customer provides Gerber files, bill of materials (BOM), and process requirements, and the factory produces...

Panelization Connection: V-cut/Stamp Holes/ Dummy Strips
Apr 25,2025
The last article we learned about the PCB several ways to put together the board, then Panelization should take into account the connection between the board, there are generally three kinds: V-CUT, stamp holes and Dummy strips. V-cut for the rule of the board is used more, as long as the two boards put together, leaving a little space between them (the gap between the V-cut) can be. Stamp holes a...
