Chipshooters - SMT Basics
Surface-mount technology is needed for the quick pace and highly accurate placement of electrical components through the possible insertion of capacitors, two-terminal electronic components, microchips and more into various computer system applications. Currently, mass products are manufactured solely on top-performance assemblers called pick and place machines or chip shooters. As a result, quick turnover times are essential for any mass-market producer ensuring a need for surface-mount technology that is both accurate and reproducible at a constant and consistent rate.
In brief, the machine itself is made up of individual components operating together to form a larger unit. The technology collects materials from a belt before transporting them to the assembler. The conveyor travels in a way that always ensures proper component collection often on paper or plastic tape that is fed into the machine using a feeding mechanism. Each machine carries numerous feeders and multiple rotating heads. The more efficient this process moves, the more efficient a product will be manufactured. The conveyor moves the component into the robotic machine where it can be clamped and precisely placed for the insertion of a surface-mount device (SMD) through the use of laser recognition and optical inspection. Once centred, nozzles grab these components from the tape feeders, then organize them into position, before placing the correct pads onto the components. The machine then determines if the correct SMD has been mounted after going over a system of checks to determine if the SMD was mounted properly onto the intended parent circuit board.
This cutting edge technology includes copious amounts of advantages over other out-dated methods including the older 'through-hole method.' Not only do chip shooters assure faster assembly and less cost per parts, the technology prevents more errors, uses smaller components, involves simpler assembly and produces many more connections per each component. Chip shooter technology enjoys many more advantages over previous methods, namely, sophistication and improved accuracy. Furthermore, when errors do occur, small component placement errors will be corrected automatically and instantly ensuring better mechanical performance. Most chip shooters are capable of placing tens of thousands of components in just 30 minutes.
At present there are numerous SMT manufacturers. However, the main manufactures of surface-mount technology include a number of companies including Siemens, Yamaha, FUJI, JUKI, Panasonic, Universal and Samsung.
