There also is a growing realization that fractures do not occur strictly on the manufacturing line. Amazon Second Lpc Pass it on, trade it in, give it a second life. Mudasir Ahmad, manufacturing engineer, Cisco Systems, may be contacted at ; mudasir. With increased utilization of strain measurement in electronics manufacturing, different SGT methodologies have been developed.

However, it is important to note that pro-active SGT can result ultimately in significant cost savings. If you are a seller for this opc, would you like to suggest updates through seller support? Amazon Drive Cloud storage from Amazon.

While BGA package and overall system-design trends have decreased flexure tolerances, the switch to lead-free solder alloys has introduced fresh concerns. Amazon Advertising Find, attract, and engage customers.

Removing components can alter the mechanical response of the board, repositioning gages can result in irrelevant strain. Such baseline data can give component suppliers i;c estimates of end-use strain levels applied to devices. Process steps with excessive strain are identified for optimization.

This has led to concerns of SLI failure due to excessive flexure. While the industry may never be able to fully eradicate solder-joint fractures, the use of SGT will help companies develop more robust manufacturing processes and increase product quality and reliability levels. View shipping rates and policies Average Customer Review: This standard addresses the development and application for shock testing to surface mount components on PCBs.


To further complicate matters, a single component may be subjected to many distinct system environments, leading to confusion about component qualification testing.

This information will enable companies to execute SGT in a standardized and consistent manner. AmazonGlobal Ship Orders Internationally.

Higher soldering temperatures also can have an adverse impact on the reliability of the PCB, inducing failure modes such as warpage, delamination and Cu-trace cracking. However, before the industry can fully realize the benefits of SGT, there are more hurdles that should be overcome.

This facilitates the development of more effective enclosure and stiffer designs.

Of particular concern is the impact of lead-free solder on the reliability of PCBA interconnects. Would you like to tell us about a lower price? The process involves attaching strain gages on circuit board assemblies at specified locations Figure 2.


With the recognition that a growing need exists for the SGT of PCBAs, 97033 of strain gages and related instruments have been developing products including applications know-how to meet the needs of users in this industry.

Board-flexure control using strain gage measurement has become an effective method for preventing these failures. Get to Know Us. Explore the Home Gift Guide. Many 97703 may find flexure to be a problem as they ramp up to full lead-free production.

IPC Mechanical Shock Test Guidelines for Solder Joint Reliability: IPC: : Books

Dynamic strain measurements are captured for all manufacturing and test processes. Manufacturers also have been aggressively developing SGT capability and consistent processes for use across their factories. It is clear that more research is required before the industry can iipc on a common approach to strain limits. Research is still on-going to assess whether SAC may be more fragile due to the formation of the interfacial intermetallics and the associated existence of Kirkendall voids near the interface.


Data icp being accumulated by the industry on the reliability of components that are subjected to the higher soldering temperatures for SAC.

When paired with computational analysis techniques, SGT provides insights on the stresses that critical packages are subjected to during such conditions. These devices, though less susceptible than BGAs, can develop cracks that could propagate in field operations.

Read more Read less. Efforts to reduce the cost of testing will ease adoption by smaller companies. Board-flexure control using strain gage measurement has proven effective in preventing these occurrences, and continues to gain acceptance as a method to identify stressful processes during manufacturing, handling, testing and assembly.

As SGT continues to gain momentum in the electronics industry, it is clear that it has evolved from a simple failure-analysis method to a standardized process-characterization tool. Some capacitor vendors specify allowable strain limits. Discover Prime Book Box for Kids.


Write a customer review. For many vendors, cost is an important factor when implementing routine SGT on their fixtures. Stacked rosette strain gage with pre-attached wires.
