In this white paper, we discuss the pros and cons of five analytical techniques when applied to residue analysis on electronic assemblies. We evaluate the following for their application and limitations for analyzing both visible and invisible residues: FITR, SEM/EDX, XRF, Ion Chromatography, and ROSE

Scavenging, Site Dressing, Residual Solder Removal. What's in a name? "That which we call an onion, by any other name would smell as strong" (apologies to the immortal bard). And, regardless of the name you give it, the objective is the same, namely the clean up of remaining solder after a component (particularly a BGA) or R.F. Shield has been removed from a PCB. This paper will describe the various methods that are available and discuss their pros and cons.

Many OEM’s require that individual wires and cables used in their products be clearly identified with a mark or label. For some, such as in the military and aerospace markets, wire and cable identification (or “wire ID”) is mandatory and the process is governed by stringent specifications, such as SAE AS50881 (formerly MIL5088L). For others, the decision to use wire ID is a voluntary one. This article will describe what type of information is typically identified on wire and cables, concepts for improved productivity, what types of systems are available and the pros and cons of each.

For many years, manufacturing has sought to increase competitiveness by moving off-shore to countries with lower labour costs. Electronic manufacturing services (EMS) companies provided an essential element to make off-shore transfer happen more quickly, offering further cost reduction opportunities from load balancing. Fierce arguments were put forward to protect the loss of local jobs, although the result was, in almost all cases, inevitable. Today, however, the whole market of PCBbased electronics products has changed significantly. The "pros" of off-shoring are no longer what they once were, and the "cons" are becoming more significant because off-shore manufacturing can no longer satisfy the needs of the market. In this paper, we expose the real costs of off-shore manufacturing, and put labour cost differentials into perspective. We demonstrate how practically, using existing technologies, re-shored manufacturing can yield better business return, either for an OEM, or through EMS providers.

For centuries, the squeegee blade has been used throughout many applications for depositing viscous materials through screens and stencils to transfer images on to substrates, from cloth material to electronic circuit boards. One area of blade printing mechanics that have been reviewed many times is the angle of attack of the blade. Typically it has been tested from 45 degrees to 60 degrees to optimize the printing quality and efficiency. However, this typically ends up as a compromise, from fill characteristics (45 degrees) to print definition (60 degrees). This paper will present the revolutionary performance of the profiled squeegee blade, which has recently been developed to create a virtual multi angle of attack for unsurpassed process control for all types of stencil printing processes.
