Different SMD package types describe physical characteristics of different devices that use surface mount technology for attaching electronic components directly to the surfaces of printed circuit boards. In other words, an SMD is an electronic component that attaches to a PCB with SMT. This attachment method is faster than through hole technology, which requires inserting component leads into drilled holes.
SMT supports the use of automated equipment and is a good choice for miniaturized components. Today, it is used widely with resistors, capacitors, transistors, diodes, and integrated circuits. Typically, SMD packages are named after their physical dimensions or have alphanumeric or lettered codes. The Solid State Technology Association defines standards and some packages conform to EIA specifications.
Through-hole components (THCs) are suitable for high-reliability products calling for stronger bonding between layers because they are able to withstand higher environmental stress with their leads going through board holes, which is the main reason that THT has been widely applied in military and aerospace products that may suffer from extreme acceleration, collision or high temperature. Furthermore, through-hole technology is also embraced by testing and prototype that sometimes call for manual adjustment and replacement.
Through-hole components come in two types: axial lead components and radial lead components. Axial lead components contain a straight line going through whose terminals go through components. During the process of THA, two ends of the lead go through holes that are drilled on circuit board so that components are closer and flatter to board. The following image demonstrates typical axial lead components.
The Final Assembly Test Packaging (FATP) philosophy provides a total solution-based on Panasonic worldwide production experiences. In cooperation with the customer and external system integrators, Panasonic develops a concept for highly efficient, cost-saving final assembly lines.
Integrated into a MES-environment Panasonic electronic manufacturing solutions, PLR or double-arm robots and potential external solutions are combined for various applications like in the consumer electronics, automotive or automation industry.
Based on the process management method and the cooperation with excellent system integrators, Panasonic is able to design assembly lines, which ensure the process and product quality on the highest level.
All process steps are fully monitored and visualized. Machines and robots out of the internal and external portfolios are put together individually, configurated according to the customer needs.
