In recent years, a growing number of electronic devices are being incorporated into automotive and other high reliability end products where the challenge is to make these devices more reliable. The package size of the devices is largely driven by the consumer industry with their sizes getting smaller making it harder to assemble and be reliable at the same time. For automotive and other high reliability electronics product, it is of the utmost priority to secure high reliability because it directly involves human life and safety. Challenges include selecting an appropriate solder alloy and having good reliability of the solder paste flux.

Automated optical inspection (AOI) and automated X-ray inspection (AXI) have been around for some time in various configurations and both have played a role in improving the quality of circuit boards. While some companies opt for one technology over the other, each form of inspection contributes its own unique benefit to the manufacturing process.

This article provides practical and affordable Design-for- Test (DFT) and Design-for-Inspection (DFI) methods that will have a positive impact on product costs, yield, reliability, and time-to-market. The properties of testability (including controllability and observability) will be analysed as they relate to analogue and digital design rules and their cause/effect, as well as the electrical and physical characteristics of proper PCB design.

SMD capacitors and resistors have small sizes and many models. Some manufacturers buy a lot of products and do not use them up in time. The problem of storage is always a headache. So how should chip capacitors and resistors be stored? There are also precautions when using chip capacitors. Please see the following information and hope it will help you.

Recent investigations have revealed that Pb-free solder joints may be fragile, prone to premature interfacial failure particularly under shock loading, as initially formed or tend to become so under moderate thermal aging. Depending on the solder pad surface finish, different mechanisms are clearly involved, but none of the commonly used surface finishes appear to be consistently immune to embrittlement processes. This is of obvious concern for products facing relatively high operating temperatures for protracted times and/or mechanical shock or strong vibrations in service.

The complexity and programmability of modern embedded boards means that knowledge built up during debugging and testing must be regarded as Intellectual Property (IP) and therefore preserved. But many of the processes and tools used today do not provide a means to preserve or pass on this IP, and thereby forego valuable opportunities to save time and improve quality during subsequent stages of product development.

With the use of laser light for reflow having been established, all that remains is to apply it to best effect. Each time a laser is fired, it pumps a specific amount of energy at a particular wavelength to a particular point in space. Where technique comes in is choosing where and for how long to apply that light along with the application of accessory equipment to optimize solder paste reflow. This presentation covers the specifics of how to determine which process choices are the right process choices based on the needs of your product to maximize yield and throughput.

As several industry pundits have expressed in recent years: "the era of 'one test method fits all' seems well behind us." For most test managers with even a modest mix of products, trying to formulate a test policy/philosophy has become a tricky balancing act at the best of times. James Stanbridge, Sales Manager UK for JTAG Technologies, and Steve Lees Managing Director of ATE Solutions look at the options.

Printed circuit boards are the base of electronic products in a variety of consumer and industrial applications. New PCBs always perform well. However, their performance will deteriorate with time due to exposure to different environmental conditions like condensation, moisture, contamination of the iconic material on the surface, dust and dirt, mildew, alpha particles, etc. To avoid these problems, PCBs are protected with conformal coatings. Let’s see how this is done, and how they protect PCB components.

Diabetes affects many millions of people worldwide. New technology for real-time glucose measurement replaces the usual unpleasant pricking of a finger: a sensor located in the subcutaneous tissue of the diabetes patient measures the glucose values and transmits them to a receiver. Production of such medical wearables calls for high-precision dispensing systems for applying very small amounts of UV adhesives to medical PCBs and for integrated system concepts to achieve this. A perfect task for Scheugenpflug.
