Do you have an idea for an electronic product, the next must-have gadget, music or video system, time saver, or the greatest problem-solving device that was ever invented? Before you begin designing the product, there are a number of tasks that you must complete and issues that you must resolve before you have an actual product design that can be produced, marketed, and sold. This article will provide you with some guidelines to assist you in getting your idea turned into a successful design. Other issues, such as whether or not to apply for a patent for your product idea and in detail how a particular product should be advertised or marketed will not be addressed in this article.

The increased interest in halogen-free assemblies is a result of Non-Government Organizations (NGOs) exerting pressure on electronic equipment manufacturers to eliminate halogens. The NGOs primary focus is on resolving global environmental issues and concerns. As a result of an increase in the enormous "e-waste" dump sites that have begun showing up around the world, NGOs are pushing consumer electronic manufacturers to ban halogen-containing material in order to produce "green" products. Not only are these sites enormous, but the recycling methods are archaic and sometimes even illegal.This stockpiling and dumping has created growing political and environmental issues. In order to deal with this issue, the question of why halogens are a focal point must be addressed.

For the past few years there has been a shift in the Lighting Industry that has carried over to the surface mount technology assembly line. What is this shift you may ask? Well it is the LED revolution. This revolution or change in lighting has some very promising results already in practice and many more companies looking to implement the LED technology into their product portfolio's. With a number of companies looking to expand their portfolio to include LED fixtures there has been an increase in the number of companies that have started their own SMT lines, as well as a significant number of contract manufacturers to meet this new industries demands (...)This presentation will discuss some issues in the pick and place process for LEDs and presents a method to troubleshoot and resolve these issues.

With the pitch size of interconnect getting finer and finer, the bonding strength between flexible and rigid (e.g. PCB, ceramic) substrates becomes a serious issue because it is not strong enough to meet the customer’s requirement. Capillary underfill has been used to enhance the bonding strength between flexible and rigid substrates, but the enhancement is very limited, particularly for high temperature application. The bonding strength of underfilled flexible/rigid interconnect is dramatically decreased after being used at 180◦C, and the interconnects are weakened by the internal stress caused by the expansion of underfill at high temperatures. In order to resolve reliability issues of the interconnect between flexible/rigid substrates, solder joint encapsulant was implemented into the thermal compression bonding process, which was used to manufacture the interconnect between flexible/rigid substrates. Compared to the traditional process, the strength of the interconnect was doubled and the reliability was significantly improved in high temperature application.

3D packaging has recently become very attractive because it can provide more flexibility in device design and supply chain, reduce the gap between silicon die and organic substrate, help miniaturize devices and meet the demand of high speed, provide more memory, more function and low cost. With the advancement of 3D packaging, the bump height is now down from 80μ to 10μ. When the bump diameter is 20-40μ and height 10μ, the process and reliability are obvious issues. It is well known that underfill can enhance the reliability for regular flip chip, however underfill won’t help assembly process. In order to resolve some difficulties that 3D packaging faces, YINCAE Advanced Materials, LLC has developed solderable anisotropic conductive adhesives for 3D package applications. In this paper we will discuss the assembly process and reliability in detail.

With the miniaturization of electronic device, Land Grid Array (LGA) or QFN has been widely used in consumer electronic products. However there is only 20-30 microns gap left between LGA and the substrate, it is very difficult for capillary underfill to flow into the large LGA component at room temperature. Insufficient underfilling will lead to the loss of quality control and the poor reliability issue. In order to resolve these issues, a room temperature fast flow reworkable underfill has been successfully developed with excellent flowability. The underfill can flow into 20 microns gap and complete the flow of 15mm distance for about 30 seconds at room temperature. The curing behavior, storage, thermal cycling performance and reworkability will be discussed in details in this paper.
