Control of the Underfill of Surface Mount Assemblies by Non-Destructive Techniques

Technical Library | 2016-04-28 14:43:23.0

Underfilling is a long-standing process issued from the micro-electronics that can enhance the robustness and the reliability of first or second-level interconnects for a variety of electronic applications. Its usage is currently spreading across the industry fueled by the decreasing reliability margins induced by the miniaturization and interconnect pitch reduction. (...) This paper will address the control of surface mount under filled assemblies, focusing on applicable inspection techniques and possible options to overcome their limitations.

Best Practices for Improving the PCB Supply Chain: Performing the Process Audit

Technical Library | 2018-08-03 14:37:59.0

In the electronics industry, the quality and reliability of any product is highly dependent upon the capabilities of the manufacturing suppliers. Manufacturing defects are one of the top reasons why companies fail to meet warranty expectations. These problems can result in severe financial pain and eventual loss of market share. What a surprising number of engineers and managers fail to realize is that focusing on processes addresses only part of the issue. Supplier selection also plays a critical role in the success or failure of the final product.

Analysis of Inspection of DPA Test Requirements Applied To Flip Chip Technologies

Technical Library | 2020-01-22 22:52:02.0

Flip chip assembly techniques bring a wide range of benefits: Reduced parasitic interconnection between the semiconductor die and package. Provides a high final assembly integrity density. Minimize the interconnection length, providing better electrical performances, especially for high speed signals. Reduce the device size and weight,…, etc. But there is no dedicated inspection requirements nor DPA standard which address all the necessary aspects associated to this construction type or only cover partially the topics to be inspected.

Big Data as a Promoter of Industry 4.0: Lessons of the Semiconductor Industry

Technical Library | 2021-12-02 01:51:28.0

The catchphrase "Industry 4.0" is widely regarded as a methodology for succeeding in modern manufacturing. This paper provides an overview of the history, technologies and concepts of Industry 4.0. One of the biggest challenges to implementing the Industry 4.0 paradigms in manufacturing are the heterogeneity of system landscapes and integrating data from various sources, such as different suppliers and different data formats. These issues have been addressed in the semiconductor industry since the early 1980s and some solutions have become well-established standards. Hence

Counterfeit Materials Prevention

Technical Library | 2022-10-04 16:54:38.0

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

Printable Electronics: Towards Materials Development And Device Fabrication

Technical Library | 2023-03-13 19:06:53.0

Purpose – There has been increasing interest in the development of printable electronics to meet the growing demand for low-cost, large-area, miniaturized, flexible and lightweight devices. The purpose of this paper is to discuss the electronic application of novel printable materials. Design/methodology/approach – The paper addresses the utilization of polymer nanocomposites as it relates to printable and flexible technology for electronic packaging. Printable technology such as screen-printing, ink-jet printing, and microcontact printing provides a fully additive, non-contacting deposition method that is suitable for flexible production.

Combining 3D Printing And Printable Electronics

Technical Library | 2023-06-02 18:52:27.0

A platform that enables the integration of conductive traces and printed three dimensional mechanical structures has been developed. We discuss the development of the platform and address issues that arise when combining 3D printing and printable electronics. We demonstrate a rapid prototyped three dimensional conductive trace and propose future applications for the platform.

Packaging Technology and Design Challenge for Fine Pitch Micro-Bump Cu-Pillar and BOT (Direct Bond on Substrate-Trace) Using TCNCP

Technical Library | 2015-12-02 18:32:50.0

(Thermal Compression with Non-Conductive Paste Underfill) Method.The companies writing this paper have jointly developed Copper (Cu) Pillar micro-bump and TCNCP(Thermal Compression with Non-Conductive Paste) technology over the last two+ years. The Cu Pillar micro-bump and TCNCP is one of the platform technologies, which is essentially required for 2.5D/3D chip stacking as well as cost effective SFF (small form factor) package enablement.Although the baseline packaging process methodology for a normal pad pitch (i.e. inline 50μm) within smaller chip size (i.e. 100 mm2) has been established and are in use for HVM production, there are several challenges to be addressed for further development for commercialization of finer bump pitch with larger die (i.e. ≤50μm tri-tier bond pad with the die larger than 400mm2).This paper will address the key challenges of each field, such as the Cu trace design on a substrate for robust micro-joint reliability, TCNCP technology, and substrate technology (i.e. structure, surface finish). Technical recommendations based on the lessons learned from a series of process experimentation will be provided, as well. Finally, this technology has been used for the successful launching of the company FPGA products with SFF packaging technology.

Non-Contact Streaming Technology Enhances the Dispense Process

Technical Library | 2009-09-16 15:13:58.0

The dispensing industry within electronics manufacturing represents a very diverse marketplace indeed; many different materials can be applied in many different ways. One high-growth area in this market is underfill, driven by the explosive demand for hand-held devices (HHDs). This segment is comprised of popular consumer goods, such as cell phones, mp3 players, GPS navigators, PDAs, portable games and ultra-mobile PCs. A new, non-contact dispense technology, known as Streaming, has recently been introduced to specifically address the incumbent needs associated with underfill.

Can Nano-Coatings Really Improve Stencil Performance?

Technical Library | 2017-10-26 01:18:49.0

Nano-coatings have been introduced by various manufacturers, with the promise of addressing some of the challenges relative to solder paste printing. Stated benefits include: Reduced underside cleaning, reduced bridging, improved solder paste release and improvements in yield. With several nano technologies already on the market and more likely to be introduced, how can the performance be quantified? How robust are these coatings? How can an assembler approach the ROI of these coatings? What hidden benefits or negative impacts should be considered? This paper will present a rigorous method for evaluating the performance and economic benefits of solder paste stencil nano-coatings.
