ASSESSMENT OF ACCRUED THERMO-MECHANICAL DAMAGE IN LEADFREE PARTS DURING FIELD-EXPOSURE TO MULTIPLE ENVIRONMENTS

Oct 11, 2022 | Pradeep Lall, Ph.D., Rahul Vaidya and Vikrant More and Kai Goebel, Ph.D.

Electronic assemblies deployed in harsh environments may be subjected to multiple thermal environments during the use-life of the equipment. Often the equipment may not have any macro-indicators of damage such as cracks or delamination. Quantiication of thermal environments during use-life is often not feasible because of the data-capture and storage requirements, and the overhead on core-system functionality. There is need for tools and techniques to quantify damage in deployed systems in absence of macro-indicators of damage without knowledge of prior stress history. The presented PHM framework is targeted towards high reliability applications such as avionic and space systems. In this paper, Sn3.0Ag0.5Cu alloy packages have been subjected to multiple thermal cycling environments including -55 to 125C and 0 to 100C. Assemblies investigated include area-array packages soldered on FR4 printed circuit cards. The methodology involves the use of condition monitoring devices, for gathering data on damage pre-cursors at periodic intervals. Damage-state interrogation technique has been developed based on the Levenberg-Marquardt Algorithm in conjunction with the microstructural damage evolution proxies. The presented technique is applicable to electronic assemblies which have been deployed on one thermal environment, then withdrawn from service and targeted for redeployment in a different thermal environment. Test cases have been presented to demonstrate the viability of the technique for assessment of prior damage, operational readiness and residual life for assemblies exposed to multiple thermo-mechanical environments. Prognosticated prior damage and the residual life show good correlation with experimental data, demonstrating the validity of the presented technique for multiple thermo-mechanical environments....

MECHANICAL FAILURES IN PB-FREE PROCESSING: EVALUATING THE EFFECT OF PAD CRATER DEFECTS ON PROCESS STRAIN LIMITS FOR BGA DEVICES

Oct 11, 2022 | John McMahon and Brian Gray

The increased temperatures associated with Pb-free processes have produced significant challenges for PWB laminates. Newly developed laminates have different curing processes, are commonly filled with ceramic particles or micro-clays and can have higher Tg values. These changes which are aimed at improving the materials resistance to thermal excursions and maintaining electrical integrity through primary attach and rework operations have also had the effect of producing harder resin systems with lower fracture toughness....

LEAD-FREE FLUX TECHNOLOGY AND INFLUENCE ON CLEANING

Oct 11, 2022 | Ning-Cheng Lee, Ph.D.

Lead-free flux technology for electronic industry is mainly driven by high soldering temperature, high alloy surface tension, miniaturization, air soldering due to low cost consideration, and environmental concern. Accordingly, the flux features desired included high thermal stability, high resistance against burn-off, high oxidation resistance, high oxygen barrier capability, low surface tension, high fluxing capacity, slow wetting, low moisture pickup, high hot viscosity, and halogen-free. For each of the features listed above, corresponding desired chemical structures can be deduced, and the impact of those structures on flux residue cleanability can be speculated. Overall, lead-free flux technology results in a greater difficulty in cleaning. Cleaner with a better matching solvency for the residue as well as a higher cleaning temperature or agitation are needed. Alkaline and polar cleaner are often needed to deal with the larger quantity of fluxing products. Reactive cleaner is also desired to address the side reaction products such as crosslinked residue....

Counterfeit Materials Prevention

Oct 04, 2022 | Lockheed Martin Corporation

Counterfeiting is growing in exponential proportions with respect to the types of: • Products being counterfeited • Industries affected • Potential consequences caused by counterfeits If this threat is not adequately addressed, counterfeit items have the potential to seriously compromise the safety and operational effectiveness of our products. The objective of this training is to raise awareness of: • The risks and impacts of counterfeit parts infiltrating the supply chain. • Best practices to eliminate or mitigate those risks • Lockheed Martin counterfeit prevention requirements for suppliers...

Methods Used In The Detection Of Counterfeit Electronic Components

Oct 04, 2022 | Harold "Woody" Hewett

In this paper I will discuss the different methods and equipment used to detect counterfeit electronic parts, specifically integrated circuits as well as demonstrate some of the "red flags" that help to identify a part as being suspected counterfeit. We will begin with the initial receipt of the parts and the examination of the outer packaging, the basic visual inspection of the parts, the visual inspection and documentation at high magnification, permanency marking, blacktop test, scrape test, XRF (RoHS), decapsulation, X-ray, basic electrical testing, C-SAM, full function testing and limited function testing....

Dispensing Thermally Conductive Materials

Sep 29, 2022 | Scheugenpflug

Electronic vehicles, devices and components must not overheat, otherwise they may fail to operate correctly. Thermal management is a major technical challenge as components are getting smaller, power densities are increasing and demands on robustness and reliability are becoming more stringent. To prevent power losses or defects resulting from overheating, liquid thermal interface materials (TIMs) are being increasingly used to dissipate their heat. This White Paper discusses the aspects that need to be taken into account when dispensing these mostly highly viscous, highly abrasive materials and why in many cases they are better alternatives to pads, tapes and foils....
