Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2] An electrical component mounted in this manner is referred to as a surface-mount device ( SMD ).
Internal details of a two head, gantry style pick-and-place JUKI SMT machine. In the foreground are tape and reel feeders, then the (currently empty) conveyor belt for printed circuit boards, and in back are large parts in a tray. The gantry carries two pickup nozzles, flanking a camera (marked "do not touch" to avoid fingerprints on the lens).
The development of the SMT process actually evolves from the thick film process. Also mounting of naked dies (the actual silicon chip without encapsulation) and wire bonding is a standard process, this provides the basis for miniaturization of the circuits as all the extra encapsulation is not necessary.
Four-PCB panel. Depaneling or depanelization is a process step in high-volume electronics assembly production. In order to increase the throughput of printed circuit board (PCB) manufacturing and surface mount (SMT) lines, PCBs are often arranged in a process called panelization so that they consist of many smaller individual PCBs that will be used in the final product.
The image is then processed by image processing software that detects the position and size/ shape of expected features (for process optimization) or presence/ absence of unexpected/ unintended objects or features (for anomaly detection). X-rays are generated by an x-ray tube, usually located directly above or below the object under inspection.
A 3 GHz model of the Intel Pentium 4 processor that incorporates Hyper-Threading Technology [7]. Hyper-Threading Technology is a form of simultaneous multithreading technology introduced by Intel, while the concept behind the technology has been patented by Sun Microsystems.
The 5DX performed a non-destructive structural test using X-ray laminography to take 3D images of an assembled printed circuit board using 8-bit grayscale to indicate solder thickness. It was used in the assembled printed circuit board (PCB) electronics manufacturing industry to provide process feedback to a surface mount technology assembly ...
An Automated Optical Inspection device. Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew).
