MacDermid Alpha to Present Research on High-Reliability Alloys at SMTA Philadelphia Chapter Meeting

Reading time ( words)

MacDermid Alpha Electronics Solutions, a world leader in the production of electronics soldering and bonding materials, will present at the SMTA Philadelphia Chapter meeting being held on March 12th, 2020 at Lutron Electronics, Inc. in Coopersburg, Pennsylvania.

Jason Fullerton, Customer Technical Support Engineer at MacDermid Alpha, is one of two featured speakers at this event. Fullerton will present Advances in Lead-free Solder Technologies for High Reliability Applications. This paper will explore lead-free alloy development, enhancements in solder paste performance, and processing differences between these alloys and typical SAC and tin-lead alloys. “Environmental regulations have driven the electronics industry to adopt lead-free solders. However, high reliability applications continue to use legacy tin-lead solder alloys,” said Fullerton. “We’ll discuss how evolving designs, service environments, and reliability requirements have driven development of new types of solder alloys.”

The second speaker will be Greg Smith, Manager of Stencil Technology at BlueRing Stencils. Smith will present Root Cause Stencil Design for SMT Components Thermal Lands. This paper will explore recent studies on stencil design to minimize voiding on quad flat no-lead (QFN) thermal lands and the effect of the window pane design on void area percentage after reflow for surface mount technology (SMT) component thermal pads without introducing float to the component. Areas of focus will be specific window pane gap sizes, total area printed, and the distance of the outer pane edges to the copper thermal land edge will be varied to determine guidelines for thermal pad stencil design.

The Chapter Meeting will begin at 5:15 pm with dinner and networking, followed by the presentations which begin at 6:15 pm. This is the first meeting organized by newly appointed Chapter President, Anna Lifton, Research and Development Manager at MacDermid Alpha. Event sponsors are StenTech and Argo/Zeta with Lutron Electronics hosting the evening’s event.

The event is open to SMTA members and non-members. Those interested can register at the Philadelphia Chapter page on the SMTA website.

SMTA Europe Webinar: What Is a Good Solder Joint, and How Can Solder Joints Be Tested?

11/18/2020 | Pete Starkey, I-Connect007
What is a good solder joint? And how can they be tested not only for purposes of process characterisation, optimisation, monitoring, and control but also for ensuring their long-term reliability? Pete Starkey details a webinar organised by the Europe Chapter of SMTA that was presented by Bob Willis, an expert in soldering, assembly technologies, and failure analysis.

This Month in SMT007 Magazine: Test and Measurement in a Smart Factory

11/03/2020 | Nolan Johnson, I-Connect007
Nolan Johnson spoke with MIRTEC President Brian D’Amico about how the role of test and measurement equipment is changing in the smart factory and how shops can adjust to make use of the new technology. D’Amico shares this insight: “While approximately 90% of U.S. electronics manufacturers recognize the potential of Industry 4.0 to improve productivity, many are slow to adopt smart factory solutions within the manufacturing process.”

Reducing Flux Splatter in Sensors and Camera Modules

10/30/2020 | Jasbir Bath, Shantanu Joshi, and Noriyoshi Uchida, Koki Solder America And Koki Company Limited
With the increased use of electronics in new technology areas, flux formulations are being developed to address the new and existing requirements. For sensors and camera modules used for Advanced Driver Assistance System (ADAS) and internet of things (IoT) applications, there is a demand for no-clean flux formulations in lead-free solder paste, which can reduce flux splattering during reflow.
