This article presents design guidelines for helping users of HDMI mux-repeaters to maximize the device's full performance through careful printed circuit board (PCB) design. We'll explain important concepts of some main aspects of high-speed PCB design with recommendations. This discussion will cover layer stack, differential traces, controlled impedance transmission lines, discontinuities, routing guidelines, reference planes, vias and decoupling capacitors....

Over the past several years, post-reflow defluxing of circuit assemblies has gained in popularity. Microminiaturization of components and boards, combined with higher expected reliability and increased product liability, have contributed to the prominence of defluxing. Lead-free solder paste - with its higher reflow temperatures and negative effects on flux - increase the likelihood of post-reflow defluxing to increase a product's reliability and aesthetic appearance....

Mar 13, 2009 | Lars Wallin, Project Manager Live Production Events at EP shows at the Stockholm Fair IPC European Representative.
Open product reliability testing in Stockholm, Sweden in January as part of a live production event generated some quite startling results. It was apparent that many components simply cannot handle the high reflow temperatures of a lead-free soldering process, and that many surface-mount machine suppliers are battling significant problems with QFN packages and other components that are mounting edgeways (bill boarding). However, some suppliers have achieved good results....

In a recent survey of 89 organizations conducted by Whataboutquality.com, respondents were asked what few key characteristics defined quality, in the eyes of their customer, the most popular response was: the product or service met my requirements. The next two most popular responses were: it worked like I expected and it was a good value, worth what I paid for it (...) So how do you continue to exceed customer expectations and simultaneously reduce costs? There are two paths to take. You can find and reduce the variation in your process and you can eliminate as much of the non-value-added waste in your operation....

One proven method used to treat clogged arteries employs tubular, mesh-like metal structures, known as stents, inserted into an affected artery to relieve the blockage. Bare metal stents often cause a condition called restinosis, the buildup of scar tissue around the stent, causing re-blockage. To counter this, polymer coatings containing drugs that are released over time are used to inhibit restinosis. Applying coatings to stents, which have intricate geometries, is challenging. Using ultrasonic atomizing spray nozzles has proven effective in achieving continuous and uniform coatings. This paper describes the unique nozzle designs employed, the methodology used, and the results obtained....

This paper describes a new approach to drying circuit board assemblies that significantly reduces the cost of ownership of an aqueous cleaning system. Drying performance is increased through a hybrid drying process that reduces energy input, exhaust requirements and sound levels. The combination of high temperature blow-off and convection brings the flexibility to tailor drying performance to fit the product's drying requirements....
