A Conversation about the IPC Cleanliness Standard & How to Comply with Graham Naisbitt

Today, we’re going to talk about cleanliness testing of post-reflowed circuit assemblies. In late 2018, IPC shocked the electronic assembly community by introducing an amendment to section 8 of the J-STD-001G. This amendment radically changed the way industry determines cleanliness. Now, assemblers must prove their assemblies are clean enough not to experience electro-chemical migration events which would cause the assembly to fail. 

This new process of obtaining objective evidence has been met with a considerable degree of confusion. To help clear up the confusion, I invited Graham Naisbitt to be my guest. Graham is an IEC 1906 Lord Kelvin Award Winner, IEC TC91 WG2, 3 and 10 Maintenance Leader of 4 Standards.
Graham is Vice-Chair of the IPC 5-30 Cleaning and Coating Sub-Committee which oversees 15 IPC Standards Development Committees and recipient of 14 IPC Standards Awards. Graham is also a British Standards Institution EPL-501 Member.

Graham is a specialist in Surface Insulation Resistance Testing, Ionic Contamination Control, Solderability, Conformal Coating materials and application systems, Cleaning, Inspection and Test.

A Conversation with SMTA SMT Certification Course Authors Dr. Ron Lasky and Jim Hall

I spoke with Dr. Ron Lasky and Jim Hall, authors of the SMTA SMT Certification Courses (along with Phil Zarrow) about the content of these courses. I also spoke with two course students, Claire Hotvedt of Indium Corporation and Tom Watson of Kimball Electronics about their experience taking the courses and the value they received.

SMTA offers two certification courses:

• SMT Processes
• Lean Six Sigma Green Belt

Each SMTA Certification program is a three-day offering consisting of a 1.5-day workshop on topics in SMT Processes or Lean Six Sigma Green Belt. The program concludes on days two and three with an open and closed book examination (SMT Processes) and open book examination (Lean Six Sigma Green Belt.)

This is not an entry-level program. Basic algebra will be used in the workshop and examination. This challenging examination requires both written answers and calculations with the intent to enable the attendee to establish competitive credentials as “Certified” by the SMTA in SMT Processes or Lean Six Sigma Green Belt.

More information on the SMTA certification courses is available here:

A Conversation with Component Storage Expert Mike Adamson

While it may seem like an untimely topic given the current supply chain shortages, storage systems for electronic components are an important part of the electronic assembly industry. While we are still in the midst of a supply chain crisis, sooner or later this will be solved and the question of where to put all of our components will be waiting for us to answer. It’s often said we don’t have time to work on the important because we’re so busy working on the urgent. 

My guest today is Mike Adamson, Product Manager for Inovaxe Corporation, a provider of material handling products and services for the electronic assembly industry. In today’s hyper-competitive electronic assembly industry, efficiency and optimization are key to maintaining competitiveness.

A Conversation about Electric Vehicles with Indium’s Brian O’Leary

One of my favorite subjects is the electrification of automobiles, not just electric cars, which are with us now, but completely autonomous vehicles. When I was a kid in the 1960’s, we were promised flying cars by the year 2000. While that goal was not met, the real prospect of autonomous vehicles in our lifetime is extremely exciting, terrifying, and realistic. 

Brian and I discuss the future of the automobile industry and what’s required for the electronics industry and the world.
