Why Cleaning is Critical Before Conformal Coating MARCH 22nd

Join ZESTRON Academy for an informative discussion on the importance of cleaning PCBs in today’s production environments, focusing on cleaning before conformal coating. We will examine: the methods and benefits of fully cleaning PCBs, how coating over residues can result in product failures, cleanliness assessment methods used before conformal coating as well as the test methods used to assess their reliability afterward, and share expert process recommendations to ensure that your products perform as expected over the long-term.

Defluxing of Copper Pillar Bumped Flip-Chips April 26th

Flip-chip technology has become increasingly prevalent within the electronics industry due to its lower cost, increased package density, improved performance while maintaining or improving circuit reliability, and increased I/O density. Join ZESTRON Academy to review a recently presented study that involved using straight DI-water and novel low-concentration alkaline cleaning agent on copper pillar bumped flip-chips and the challenges of effectively cleaning flux residues from under these components.

DI-water vs Chemistry MAY 24TH

Join ZESTRON Academy for an in-depth look at the cleaning agent technologies and process alternatives to pure DI-water. In today’s PCB manufacturing environment, increased densities, reduced component sizes, low standoff heights, and a large variety of component packages combine to limit the effectiveness of cleaning with DI-water. Join us as we discuss key performance indicators including, cleanliness, material compatibility, power requirements, DI-water usage, and environmental impacts of using DI-water vs. chemistry.

Multiple Thermal Cycles June 21st

Today, multiple thermal cycles may be required for a variety of reasons in the production of printed circuit boards. This can include the presence of Surface Mount Technology (SMT) and Through Hole Technology (THT), stacked components and double-sided circuitry. With the potential for multiple reflows, it is more important than ever to have a cleaning process that is optimized for it. Please join ZESTRON Academy as we thoroughly examine the impact of multiple thermal cycles on the effectiveness of the PCB cleaning process.

Jet Printing and Cleaning Challenges NOV. 15TH

Today’s production environments are overcoming printing challenges by incorporating jet printing as an additional add-on step to add extra solder paste volume when needed. Typically, jet printing pastes use Type 5 and 6 solder powder compared to type 3 and 4. As cleaning remains critical to long-term reliability, jet solder pastes have proven more difficult to clean. Join ZESTRON Academy to explore the reasons behind the increased cleaning challenges with comparative cleaning trial data and customer case studies.
