The latest screen printing platforms unlock more of the potential from dual-lane processing. Simultaneous demands to enhance flexibility while increasing utilisation and overall throughput apply to manufacturers operating at virtually any point in the mix-volume continuum: capacity must work hard to deliver the required return. As these lean manufacturing principles hold sway from the US and Europe to the Far East, no modern assembler has a second to spare.

High Density Interconnect (HDI) technologies are being used widely in Asia and Europe in consumer electronics for portable wireless communication and computing, digital imaging, and chip packaging. Although North America lags behind in developing process capability for this technology, HDI will become a significant business segment for North America. For this to happen, the printed circuit board shops will have to become process capable in fabricating fine lines and spaces, and also be capable in forming and plating microvias.

Over the past 30 years we have learned that lead has negative affects on the health of humans and seen strong legislation remove it from gasoline and paints. More recently, governments in Europe and Asia have set deadlines to remove lead from consumer electronic devices that use printed circuit boards. Currently, the ban is not being applied to high reliability applications such as military or medical devices, but we all know that will come someday soon. Likewise many believe that lead free solder is coming to wafer bump reflow and are beginning to make the transition.

Over the last years more and more international newspapers reported in Europe / USA and Japan: "Tunnel train got stuck under the Channel – thousands of people stranded", "Recall of thousands of cars to workshops for control and repair", "Power Failures left households without energy for hours." Very often news like this relate to malfunctions of electric and electronic circuits under adverse conditions or sometimes even in normal operating environment (...) The presentation will deal with all kinds of aspect of cleaning to ensure the reliability of electronic circuitry in ever changing operation conditions in the most important industrial areas.

Over fifteen years has passed since North America and Europe ceased being the center of worldwide PCB fabrication, and were supplanted by a Far East market with low cost labor, more relaxed environmental requirements, and strong government support. In just a few short years, the superior cost advantages of this new dynamic put volume PCB production in the West out of business, aside for the military and specialty technology applications contained in the few shops that continue to exist today.Recently, however, the conditions which created the current equilibrium appear to be shifting again. In this new dynamic, automation, innovative green wastewater technologies, and next generation process equipment innovations have combined to make new factories capable of achieving rapid ROI for PCB fabrication almost anywhere. This paper means to illustrate this new dynamic, and provide case study examples from the new greenfield installation at the company captive facility in New Hampshire.

The electronics industry has recently undertaken the transition to lead-free processing as a direct consequence of the RoHS directive, which came into force in July 2006. However, this is unlikely to be the last transition required since the European Solvent Emissions Directive, 1999 is starting to be implemented and enforced by national governments. This is resulting in pressure on larger manufacturers, currently emitting more than 5 tonnes of solvent vapour per annum to take steps to limit and reduce their emissions.

Anisotropic Conductive Adhesive Bonding is an interconnection technique mostly used for connecting displays to pcb’s using anisotropic conductive adhesive and flex foils. For successful implementation there are a few basic constraints. If these are followed, display connection is a simple and reliable process, giving top quality connections. Heat-Sealing can be done in any factory and can be introduced in a few months, from start of design to mass productions
