In more spacious designs, tooling holes and other obstructions may be present where a gage should be placed.

This is critical during the early stages of the transition, a time when the industry has limited data on the effects of new elements introduced in the PCB, components and solder joints. 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 903 guidelines.

If you are a seller for this product, would you like to suggest updates through seller support? Would you like to tell us about a lower price? Smaller gage sizes can be more susceptible to variations in the board structure and localized strain concentration. East Dane Designer Men’s Fashion. Process steps with excessive strain are identified for optimization. This information is critical for EMS providers and their customers as it provides assurance of a safe assembly process.

While strain measurement of ICT fixtures is a critical application of SGT, adoption by test-fixture vendors is limited. Dynamic strain measurements are captured for all manufacturing and test processes. This document addresses methods to define mechanical shock use-conditions, methods to define system level, system printed board level and component test board level testing that correlate to such use conditions and guidance on the use of experimental metrologies for mechanical shock tests.

Some capacitor vendors specify allowable strain limits. These estimates will, in turn, help suppliers define the strain targets necessary for their devices. 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.

Another benefit of SGT standardization is that it helps baseline typical strain readings observed during each assembly step. Partial cracking, however, is not detected easily with non-destructive testing, and often appears only in field returns.

Data are being accumulated by the industry on the reliability of components that are 97003 to the higher soldering temperatures for SAC. For EMS providers, SGT serves kpc a process-characterization tool and allows the pro-active identification of high-strain sequences during assembly and test. Amazon Music Stream millions of songs. Amazon Advertising Find, attract, and engage customers. Amazon Renewed Refurbished products with a warranty.

This ranges from multiple high-acceleration shocks experienced by handheld devices to shipping-shock impulses on expensive enterprise infrastructure equipment. This has led to concerns of SLI failure due to ipf flexure. As we approach the July lead-free deadline, the transition to lead-free processes continues to cause anxiety. Alexa Actionable Analytics for the Web. However, before the industry can fully realize the benefits of SGT, there are more hurdles that should be overcome.

Amazon Inspire Digital Educational Resources.

Strain Gage Testing: Standardization

Shopbop Designer Fashion Brands. Board-flexure control using strain gage measurement has become an effective method for preventing these failures.

These concerns demand that the bending 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.

I;c also have been aggressively developing SGT capability and consistent processes for use across their factories. Read more Read less. However, it is important to note that pro-active SGT can result ultimately in significant cost savings.

The high strain imposed by clamps and test probes often make test fixtures a major culprit of solder-joint fracture due to excessive board flexure.

This data also can aid board designers when placing critical packages.

Such strength-based comparative evaluation was not conceivable before the standardized implementation of SGT. There also is a growing realization that fractures do not occur strictly on the manufacturing line.

This information will enable companies to execute SGT in a standardized and consistent manner.

Discover Prime Book Box for Kids. Write a customer review. There is a critical need for this test method, as designing test conditions that can replicate these varied environments is becoming increasingly difficult. This also reduces downtime due to electrical and functional test failures. With SGT, board assemblers can expect increased production yields. This is why many manufacturers are required to operate under strain levels specified by their customers or component suppliers. Amazon Drive Cloud storage from Amazon.

It is hoped that this will spark a paradigm shift in the way ICT-fixture suppliers validate products. Efforts to reduce the cost of testing will ease adoption by smaller companies.
