PCB delamination is the phenomenon of partial separation between layers of a printed circuit board (PCB) during manufacture or use. This separation is usually characterized by bubbles or blisters on the surface, which in severe cases can affect the functionality and reliability of the board. Understanding the causes and prevention of these problems is essential
The number of PCB layers is the number of layers it has in the vertical direction (usually the Z-axis). In short, it is how many layers of wiring are laid on the board. Typically, PCB boards can be categorized as single-layer, double-layer, and multi-layer. Single-layer PCB refers to the use of the same circuit wiring
Low volume PCB assembly refers to the assembly and processing of circuit board components in relatively small quantity ranges. This type of assembly typically involves orders with lot sizes between 25 and 5,000 pieces and is suitable for product design phases that require flexible production and rapid iteration.
