Microelectronics Reliability: Physics-of-Failure Based Modeling and Lifetime Evaluation

Apr 22, 2024 | Mark White and Joseph B. Bernstein

The solid-state electronics industry faces relentless pressure to improve performance, increase functionality, decrease costs, and reduce design and development time. As a result, device feature sizes are now in the nanometer scale range and design life cycles have decreased to fewer than five years. Until recently, semiconductor device lifetimes could be measured in decades, which was essentially infinite with respect to their required service lives. It was, therefore, not critical to quantify the device lifetimes exactly, or even to understand them completely. For avionics, medical, military, and even telecommunications applications, it was reasonable to assume that all devices would have constant and relatively low failure rates throughout the life of the system; this assumption was built into the design, as well as reliability and safety analysis processes....

Glue Dispensing Machine VS. Glue Potting Machine potting dosing encapsluation,glue dispenser,Meter Mix Systems, Metering, Mixing and dispensing , 2K metering, 2 part epoxy dispensing ,glue potting machine The Difference Between Glue Dispensing Machine and Glue Potting Machine? While both glue dispensing machines and glue potting machines are used in industrial and manufacturing settings for adhesive applications, they have some differences in their functionality and applications. Glue dispensing machines are designed to accurately and precisely apply adhesive materials to specific locations on a part or surface. These machines use a variety of application methods, including spray, needle or nozzle dispensing, and jetting. They are typically used in applications where a small amount of adhesive is required at a specific location or where a high level of precision is needed. They are commonly used in electronics, automotive, and medical device manufacturing. On the other hand, glue potting machines are designed to fill entire cavities or enclosures with adhesive material. They are typically used in applications where a part or assembly requires a high level of protection from environmental factors such as moisture, dust, or vibrations. Glue potting machines are used to apply a thick layer of adhesive to enclose and protect sensitive components such as circuit boards, sensors, or electronic assemblies .While glue dispensing machines and glue potting machines share some similarities in their application of adhesive material, they are typically used for different purposes and in different types of applications. In general, glue dispensing machines are used for precise, small-scale adhesive applications, while glue potting machines are used for large-scale applications where a high level of protection is needed. How to Choose a Suitable Automatic Glue Dispensing Machine? Choosing a suitable automatic glue dispensing machine can depend on a number of factors, such as the type of glue you're working with, the desired application method, the size and complexity of your project, and your budget. Here are some things to consider when choosing an automatic glue dispensing machine: Types of glue: Different automatic glue dispensing machines are designed to work with specific types of glue, such as epoxy, silicone, hot melt, or UV-curable adhesives. Make sure to choose a machine that is compatible with the type of glue you need to use. Dispensing method: Consider the method by which the machine dispenses the glue. Some machines use needles or nozzles to apply the glue, while others use spray or roller applicators. Choose a method that is appropriate for your application. Precision: If you need precise control over the amount of glue dispensed, look for a machine that has high accuracy and repeatability. Some machines use vision systems or other sensors to ensure accurate placement and amount of glue. Production volume: Consider the volume of production that you require. If you need to produce large quantities of products, you may need a faster cycle time and higher capacity machine. Integration: If you plan to integrate the automatic glue dispensing machine into an existing production line, make sure it is compatible with your equipment and software. Budget: Automatic glue dispensing machines can range in price from a few hundred dollars to tens of thousands. Consider your budget and the ROI (Return on Investment) the machine can provide before making a purchase decision. Technical support: Choose a supplier that provides good technical support, training, and maintenance services to ensure your machine runs smoothly and efficiently. By considering these factors and doing thorough research, you can choose an automatic glue dispensing machine that meets your needs and helps you achieve your production goals.

Addressing Silicone Contamination Issues

Apr 16, 2024 | Edward M. Petrie

Since adhesives and sealants must function by surface attachment, the nature and condition of the substrate
surface are critical to the success of any bonding or sealing operation. One of the most important parameters
is surface cleanliness or the absence of contaminants that can impair adhesion. There are many sources of
possible contamination to worry about. Some of these are indicated in Table 1, but the list is by no means allinclusive.

Wettable Flank Plated PQFN

Apr 08, 2024 | Bradley Smith

Plastic Quad Flat Pack No-Lead (PQFN) or Quad Flat Pack No-Lead Exposed Pad (QFN-EP) packages (a.k.a. QFN) have no easily solderable, visually exposed terminations, because the package designs have terminations on the underside of the package for solder joints. The package edge has exposed copper of the termination after singulation and does not easily solder wet due to copper oxidation. Therefore, visual determination that the package has soldered effectively cannot be made optically or by x-ray. Electrical test is the only way to determine electrical connectivity of the soldered terminations. There are some applications where full electrical test of all terminations is difficult or incomplete. Thus, in high reliability applications, it may be desired to visually check for termination solder joint integrity. It is for these purposes that wettable flank, tin plated terminations of QFNs have been developed as a visual aid to the determination of board solder operation effectiveness

Factors That Influence Side-Wetting Performance on IC Terminals

Apr 08, 2024 | Donald C. Abbott, Bernhard Lange, Douglas W. Romm, and John Tellkamp .

A designed experiment evaluated the influence of several variables on appearance and strength of Pb-free solder joints. Components, with leads finished with nickel-palladium-gold (NiPdAu), were used from Texas Instruments (TI) and two other integrated circuit suppliers. Pb-free solder paste used was tin-silver-copper (SnAgCu) alloy. Variables were printed wiring board (PWB) pad size/stencil aperture (the pad finish was consistent; electrolysis Ni/immersion Au), reflow atmosphere, reflow temperature, Pd thickness in the NiPdAu finish, and thermal aging. Height of solder wetting to component lead sides was measured for both ceramic plate and PWB soldering. A third response was solder joint strength; a "lead pull" test determined the maximum force needed to pull the component lead from the PWB. This paper presents a statistical analysis of the designed experiment. Reflow atmosphere and pad size/stencil aperture have the greatest contribution to the height of lead side wetting. Reflow temperature, palladium thickness, and preconditioning had very little impact on side-wetting height. For lead pull, variance in the data was relatively small and the factors tested had little impact....
