Mechanical shock test guidelines for solder joint reliability – CERN Document Server
Most rely on customers to conduct these tests 903 3. Many manufacturers may find flexure to be a problem as they ramp up to full lead-free production. As we approach the July lead-free deadline, the transition to lead-free processes continues to cause anxiety. This standardization effort has allowed the creation of a central database of SGT results with the long-term goal of developing better test fixture, PCB layout and process setup methods and guidelines.
While BGA package and overall system-design trends have decreased flexure tolerances, the switch to lead-free solder alloys has introduced 99703 concerns. Aside from manufacturing characterization, SGT also can be used as a mechanical design-validation tool. East Dane Designer Men’s Fashion. This has led to concerns of SLI failure due to excessive flexure. As awareness increases, it becomes obvious that SGT is a necessary tool for test-fixture vendors. Would you like to tell us about a lower price?
Perhaps the most pressing area of development is that of real estate, particularly in mobile computing platforms and small consumer devices. View shipping rates and policies Average Customer Review: In addition to BGA components, SGT also is an invaluable tool for analyzing failures on other discrete surface mount devices, such as capacitors and resistors.

This information ipcc critical for EMS providers and their customers as it provides assurance of a safe assembly process. Efforts to reduce the cost of testing will ease adoption by smaller companies.
IPC/JEDEC-9703: IPC/JEDEC Mechanical Shock Test Guidelines for Solder Joint Reliability
While strain measurement of ICT fixtures is a critical application of SGT, adoption by test-fixture vendors is limited. It is clear that more ipf is required before the industry can agree on a common approach to strain limits. Stacked rosette strain gage with pre-attached wires. When paired with computational analysis techniques, SGT provides insights on the stresses that critical packages are subjected to during such conditions.
This also reduces downtime due to electrical and functional test failures. To further complicate matters, a single component may be subjected to many distinct system environments, leading to confusion about ilc qualification testing. These estimates will, in turn, help suppliers define the strain targets necessary for their devices. These concerns demand that the ipd and flexure of the PCB during assembly, test, handling and transportation, as well as actual product application, be characterized and controlled closely to safeguard the reliability of the lead-free PCBA interconnection.
Strain Gage Testing: Standardization
Amazon Restaurants Food delivery from local ioc. Amazon Music Stream millions of songs. In practice, customer or component suppliers typically define strain limits.
With increased utilization of strain ippc in electronics manufacturing, different SGT methodologies have been developed. Amazon Second Chance Pass it on, trade it in, give it a second life. For EMS providers, SGT serves as a process-characterization tool and allows the pro-active identification of high-strain sequences during assembly and test.
Unfortunately, variations in methodology inhibit reliable data collection and prevent data comparison. Amazon Drive Cloud storage from Amazon. This information will enable companies to execute SGT in a standardized and consistent manner. Strain gage testing SGT allows objective analyses of strain conditions that SMT components are subjected to during assembly ip test. Learn more about Amazon Prime. 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.
Mudasir Ahmad, manufacturing engineer, Cisco Systems, may be contacted at ; mudasir. The document also provides reference strain limits. Standardization December 31, Related Video Included.
This ranges from multiple high-acceleration shocks experienced by handheld devices to shipping-shock impulses on expensive enterprise infrastructure equipment. Such strength-based comparative evaluation was ic conceivable before the standardized implementation of SGT.
As the electronics industry shifts toward finer-pitch BGA components, thinner PCBs and lead-free interconnects, the robustness of second-level interconnects SLIs may be affected adversely.
