The purpose of the testing was to compare the resistance and check for open circuit conditions of reworked BGA test samples made with and without StencilQuik™ after 500 thermal shock cycles. StencilQuick™ is a product of Best Inc. In this series of tests, the resistance of daisy chain resistance patterns running between the BGA and test board after exposure to thermal shock was measured.

Considerable effort is ongoing to improve the efficiency and to move towards high-volume manufacturing of photovoltaic cells. Much attention has been focused on developing in-line processes to replace the current batch processes. A critical process to improve the performance of solar wafers is the application of Dopants. The basic requirement for this process is an automated method for applying a very thin, uniform film of Dopant to the silicon wafer as part of an in-line manufacturing process.

Air-powered dispensing systems use controlled pulses of air pressure to dispense solder paste from syringe reservoirs in uniform amounts. In this paper, EFD explains the most critical variables affecting air-powered dispensing of solder pastes and shows how to manage those variables to your advantage.

This paper will review some basic past and present flux chemistries that affect flux collection methodology. It will also review some of the most common flux collection methods, self-cleaning techniques, and maintenance goals. And, finally, data will be presented from high volume production testing of an advanced flux management system.

A Manufacturing Execution System (MES) is a software program that manages and monitors production work in a factory. The MES controls and monitors all manufacturing data in real time, so there is no guesswork as to the status of any given job, machine, operator, etc. The focus is on short-interval scheduling (shift or day) with an emphasis on optimizing the distribution of work orders. Larger manufacturers have employed MES’s for years but many small to medium sized enterprises (SME’s) have yet to adopt such systems. The benefits of using an MES are many. Looking forward, I predict that even the smallest manufacturing companies will employ MES systems in the future.
