Using Automated 3D X-Ray Inspection to Detect BTC Defects

Bottom-termination components (BTC), such as QFNs, are becoming more common in PCB assemblies. These components are characterized by hidden solder joints. How are defects on hidden DFN joints detected? Certainly, insufficient solder joints on BTCs cannot be detected by manual visual inspection. Nor can this type of defect be detected by automated optical inspection; the joint is hidden by the component body. Defects such as insufficients are often referred to as "marginal" defects because ...

Assessing the Effectiveness of I/O Stencil Aperture Modifications on BTC Void Reduction

Bottom terminated components, or BTCs, have been rapidly incorporated into PCB designs because of their low cost, small footprint and overall reliability. The combination of leadless terminations with underside ground/thermal pads have presented a multitude of challenges to PCB assemblers, including tilting, poor solder fillet formation, difficult inspection and �� most notably �� center pad voiding. Voids in large SMT solder joints can be difficult to predict and control ...

The Effect of Coating and Potting on the Reliability of QFN Devices.

The fastest growing package types in the electronics industry today are Bottom Termination Components (BTCs). While the advantages of BTCs are well documented, they pose significant reliability challenges to users. One of the most common drivers for reliability failures is the inappropriate adoption of new technologies. This is especially true for new component packaging like BTCs. Obtaining relevant information can be difficult since information is often segmented and ....

Rework Challenges for Smart Phones and Tablets

Smart phones are complex, costly devices and therefore need to be reworked correctly the first time. In order to meet the ever-growing demand for performance, the complexity of mobile devices has increased immensely, with more than a 70% greater number of packages now found inside of them than just a few years ago. For instance, 1080P HD camera and video capabilities are now available on most high end smart phones or tablet computers, making their production more elaborate and ...

Body of Knowledge (BOK) for Leadless Quad Flat No-Lead/Bottom Termination Components (QFN/BTC) Package Trends and Reliability

As with many advancements in the electronics industry, consumer electronics is driving the trends for electronic packaging technologies toward reducing size and increasing functionality. Microelectronics meeting the technology needs for higher performance, reduced power consumption and size, and off ...

Custom Anvil and Press Needed -- Hello, I am looking for a machine shop in the Dallas, Texas area that can make customer press tooling by manufacturing part number, both tools will be needed anvil and press.

Dual lane SMT lines -- We are looking into setting up a new SMT line and have come across several brands that have options for dual lane lines (think YRM20DL). What scenario would a setup like this would make the most sense? Most of our products are double sided with far fewer components on the bottom side. Would running both sides in parallel make sense here? Many of our products have a large number of common components. Would dual lane make sense here for running different products in parallel?
