Meiji Techno America's SMD-5TR complete turnkey microscope package, based on our EMZ Series microscopes. Those who must work to the most demanding standards of the SMD industries require a microscope system for assembly, repair, inspection and Quality Control. The SMD Inspection Series is equipped with Meiji Techno's most versatile Boom Stand which can be adjusted vertically or horizontally and side to side to address the ergonomic needs of every production or test engineer. Equipped with an auxiliary lens which gives the user over 6 inches of working distance. This allows ample working room to allow the engineers to solder and work on PCB boards being inspected without compromising Ergonomics. An electronic device so made is called Surface-mount Device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Since different technologies can be used on the same board, with the through-hole technology used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors.

Meiji Techno America offers a variety of illuminations as an option because where components are to be placed, the printed circuit board normally has flat, usually tin-lead silver or gold plated copper pads without holes, called solder pads. Our Inspection Series allows the boards to be visually inspected for missing or misaligned components and solder bridging, if needed, they are sent to a rework station where a Meiji Techno Microscope system is used to inspect errors and repaired by a human operator. They are sent to the testing stations (in-circuit testing and/or functional testing) to verify that they operate correctly. Defective surface-mount components can be repaired by using our stereo zoom systems by using soldering irons (for some connections), or using a non contact rework system. In most cases a rework system is the better choice because SMD work with a soldering iron requires excellent Optical Microscope quality and considerable skill. This system can also be used in the SMT and Medical Device Manufacturing which requires accurately documenting, inspecting and analyzing information accurately and efficiently in your R&D division.
