ZESTRON, the globally leading provider of high precision cleaning products, services and training solutions for the electronics manufacturing industry, is pleased to announce that Naveen Ravindran, M.S.Chem.Eng., Application Engineer, ZESTRON, will present “Determine Critical Process Parameters for QFNs” at the SMTA LA/Orange Expo and Tech Forum.  The annual event will be held on November 6th, at the Grand Event Center in Long Beach, CA, from 10:00 AM to 3:00 PM.

Quad Flat No Leads (QFNs) packages are one of the fastest growing package types within the electronics industry.  Complex package design, combined with low standoff heights inhibits the complete removal of flux residues after the soldering process.  Mr. Ravindran will discuss the challenges to effectively clean underneath the QFN component body, and how partially removed residues can lead to component failure.  Furthermore, he will present a technical study that determined the critical cleaning process parameters using a spray-in-air inline cleaner and an aqueous alkaline cleaning agent in order to achieve complete cleanliness underneath these devices soldered, with both soluble lead free and no-clean lead free pastes.

The SMTA LA/Orange County Expo and Tech Forum will be held at the Grand Event Center, 4101 E. Willow Street, Long Beach, CA.  For more information, please visit SMTA.org.
