New Technology of Electronic Board Manufacturers Surface Mount Technology is the technological, surface assembly has replaced the technique of through hole technology; the method used in the process of installing components with wired cables in holes of the PCB card, crossing the plate from one side to the other. The PCB SMT assembly technology is different; connections are made through contacts on the bottom surface of the board - metal terminations around the board. A component of SMT, or an SMD is usually smaller than one of the through whole technology because it has smaller wires or does not have them at all. It can contain electronic pins, cuts or cables of different shapes, flat contacts, matrices of tin balls or alternatively metallic terminations at the edge of the circuit. As it is evident, the assembly by hand of pieces using the technology SMD is difficult, for that reason it demands the automation for example in the lines of massive manufacture. It is a very delicate technique to make an SMD design work well even in environments with high rates of electromagnetic interference. The benefits: There are many benefits with electronic board manufacturers. First, the components are smaller. There is also a better component density available, that is, more components per plate area. With SMT technology, mechanical performance is facilitated under vibration conditions. Low initial cost and cost and time for production - and many parts of Surface Mount cost less than the same part in a Through Hole component. More benefits have to do with the assembly. During the manufacture of the printed circuit, it is not necessary to drill so many holes. Automated assembly is faster and easier; because some machines are capable of installing a lot of components for a short time. In addition, if there are some errors in the placement of components, they are automatically corrected because the tension inside the molten solder pulls and realigns the components with the welding electrodes. Another benefit is that the components can be installed on either side of the printed circuit. Low resistance and inductance to the connection, which leads to less superfluous effects RF and better high-frequency performance more predictable. Source Link: https://goo.gl/Q4vyvm
