The Industry Requirement for 2D and 3D Inspection Technology in a Single AOI Platform

Technical Library | 2012-11-21 18:57:58.0

The continuing evolution toward advanced miniature packaging has led to ever increasing PCB density and complexity. As the manufacturing process becomes progressively more complicated, there is an ever increasing probability for defects to occur on finished PCB assemblies. For years the Automated Optical Inspection (AOI) industry has relied solely upon two-dimensional (2D) inspection principles to test the quality of workmanship on electronic assemblies. While advancements in conventional 2D optical inspection have made this technology suitable for detecting such defects as missing components, wrong components, proper component orientation, insufficient solder, and solder bridges; there is an inherent limitation in the ability to inspect for co-planarity of ultra-miniature chips, leaded device, BGA and LED packages.

Hand Soldering, Electrical Overstress, and Electrostatic Discharge

Technical Library | 1999-05-09 13:07:16.0

This paper will give the reader a general understanding of EOS and ESD phenomena. It specifically addresses hand soldering's role in EOS and ESD and how to protect against and test for potential problems. It discusses how Metcal Systems address EOS and ESD concerns and how they differ from conventional soldering systems.

Rework Challenges for Smart Phones and Tablets

Technical Library | 2015-04-23 18:48:18.0

Smart phones are complex, costly devices and therefore need to be reworked correctly the first time. In order to meet the ever-growing demand for performance, the complexity of mobile devices has increased immensely, with more than a 70% greater number of packages now found inside of them than just a few years ago. For instance, 1080P HD camera and video capabilities are now available on most high end smart phones or tablet computers, making their production more elaborate and expensive. The printed circuit boards for these devices are no longer considered disposable goods, and their bill of materials start from $150.00, with higher end smart phones going up to $238.00, and tablets well over $300.00.

Increase Your Process Control and Lower Cost of Ownership

Technical Library | 2012-11-12 14:06:48.0

With consumers constantly looking for lower prices on their technology products and manufacturers trying to squeak out higher margins from their production lines, the need for process control and lower overhead costs have become even more important. One sector that is often overlooked is the hand soldering area of the factory. Many factories have been struggling with antiquated soldering systems for years. In some cases they are trying to make their investment in stations last much longer than they were designed for, or they are falsely trying to recoup their original investment ‐ all at the cost of higher operating expenses or even worse, reduced operator thru‐put.

Combination of Spray and Soak Improves Cleaning under Bottom Terminations

Technical Library | 2014-10-23 18:10:10.0

The functional reliability of electronic circuits determines the overall reliability of the product in which the final products are used. Market forces including more functionality in smaller components, no-clean lead-free solder technologies, competitive forces and automated assembly create process challenges. Cleanliness under the bottom terminations must be maintained in harsh environments. Residues under components can attract moisture and lead to leakage currents and the potential for electrochemical migration (...) The purpose of this research study is to evaluate innovative spray and soak methods for removing low residue flux residues and thoroughly rinsing under Bottom Termination and Leadless Components

Taking the LED Pick and Place Challenge

Technical Library | 2014-09-25 18:16:47.0

For the past few years there has been a shift in the Lighting Industry that has carried over to the surface mount technology assembly line. What is this shift you may ask? Well it is the LED revolution. This revolution or change in lighting has some very promising results already in practice and many more companies looking to implement the LED technology into their product portfolio's. With a number of companies looking to expand their portfolio to include LED fixtures there has been an increase in the number of companies that have started their own SMT lines, as well as a significant number of contract manufacturers to meet this new industries demands (...)This presentation will discuss some issues in the pick and place process for LEDs and presents a method to troubleshoot and resolve these issues.

Parallel SmartSpice: Fast and Accurate Circuit Simulation Finally Available

Technical Library | 1999-07-20 10:35:30.0

Circuit simulation is a necessary everyday tool to circuit designers who need to constantly verify and debug their circuits during the design process. As engineers face larger, more complex designs and tighter project schedules, fast SPICE simulation with no loss in accuracy has become a necessity. Simulation indeed accounts for a large portion of the time spent in the design and optimization of a new circuit...

Cleanliness of Stencils and Cleaned Misprinted Circuit Boards

Technical Library | 2010-09-09 16:44:48.0

The effectiveness of cleaning stencils and misprinted/dirty printed circuit boards can be effectively monitored. This can be done by washing known clean circuit boards and then checking to see if they have stayed clean as a result of the washing process.
