Solder beading was found on boards that had been reflowed. It is a large solder ball embedded in a pool of flux that is positioned next to a discrete components. These components have a very low ground clearance, such as chip resistors and capacitors, thin small outline packages (TSOPs), small outline transistors (SOTs), D-PAK transistors, and resistor assemblies.
As electronic products update and iterate faster and faster, they continue to develop in the direction of high density, miniaturization, and high reliability. In order to save assembly space and reduce costs, related accessories are also constantly being upgraded, such as FPC vs FFC, which are widely used in our electrical equipment.
Both FPC vs FFC are flat and can be bent at will, so do these two similar products belong to the same category? What are their differences and similarities between FPC vs FFC?
