Basic concepts

PCBA (Printed Circuit Board Assembly) refers to the entire process in which a bare PCB receives SMT placement or DIP insertion. In electronics production, PCBA is a critical step that integrates components onto the printed circuit board to form a complete electronic assembly; common mobile phone and computer motherboards are typical examples. These assemblies are further assembled and tested to become the finished electronic products.

DFM, Design for Manufacturability, studies the relationship between a product's physical design and the various parts of the manufacturing system, and applies it during product design so that the whole manufacturing system can be optimised as a whole. It is an effective tool for communication between PCBA design and PCBA manufacturing and the core technique of concurrent engineering. Considering manufacturability and assemblability at the design stage helps products enter production more smoothly.

Communication barriers between design and manufacturing

Electronic product developers are usually well trained in circuit design principles but seldom receive systematic training in manufacturing process technology, so their understanding of manufacturing is limited and their manufacturability concepts remain vague. In PCB layout design, component selection, manufacturing process selection, thermal design and production test methods, designers often lack practical experience.
