Piezoelectric Mount Force Sensor of Placement System for Surface Mount Devices.

Optimisation for Surface Mount Placement Machines

Optimisation of feeder setup and component placement sequence are very important to the efficiency of surface mount placement machines. Much works have been conducted to solve this problem. However, the technological characteristics of the placement machine influences the nature of the planning problems to be solved and the formulation of the associated models. As a result, little consensus exi...

Reflow Soldering Guidelines for Surface - Mount Devices

Multi-Classifier Approaches for Post-Placement Surface-Mount Devices Quality Inspection

In the continuing effort to shrink the electronics components and assemblies, the need for streamlined production processes and quality assurance is emerging stronger than ever. Surface Mounted Devices (SMD) is one of the breakthrough techniques that drove printedcircuit board production to a new level, increasing substantially the component density and reducing the size of produced circuits. Q...

Two-stage high-precision visual inspection of surface mount devices

A two-stage high-precision algorithm for detecting the orientation and position of the surface mount device (SMD) is described. In the preprocessing step, a coarse orientation of the SMD is obtained by line fitting. A high-precision fuzzy Hough transform (FHT) is applied to the corner points to estimate precisely the orientation of the device, with its position determined by using four detected...

Mounting of Surface Mount Components

Over the past few year, electronic products, and especially those which fall within the category of Consumer Electronics, have been significantly reduced in physical size and weight. Products such as cellular telephones, lap-top computers, pagers, camcorders, etc., have been reduced by as much as 3/4 of their original introductory size and weight. The most significant contributing factor to thi...
