KYZEN today announced that Daniel Gao, Sales Manager – Northern China, will present during the SMTA China East Vendor Conference, during NEPCON China, scheduled to take place April 26-28, 2016 at the Shanghai World EXPO Exhibition & Convention Center. Gao will present the paper authored by Chrys Shea, Shea Engineering Services, Mike Bixenman, DBA, KYZEN, and Ray Whittier, Vicor Corporation, entitled, “Video Analysis of Solder Paste Release from Stencils.”
Gao will discuss why solder paste release from the stencil is a critical factor in print quality, and ultimately, overall electronic product quality and reliability. He will delve into the experiment devised to better understand release mechanics using a video microscope to capture the separation of the stencil from the PCB. The experiment incorporates different aperture area ratios, solder pastes, stencil nano-coatings and under wipe solvents to visualize their effects on paste release.
This study builds on previous research that developed the test setup and recording methods, and incorporates some modifications to the original experimental configuration to improve image quality. The outputs of the experiments are videos that demonstrate the effects of solder paste formulation, solvent under wiping and nano-coating on paste release at different area ratios. The paper will discuss the observations from the videos, and the presentation will play the videos.
Based in BeiJing, Gao more than 10 years of experience in semiconductor applications and electronic assemblies including wafer bumping processes, flip Chip packaging, LED packaging and PCB assembly applications. Gao has worked for KYZEN for more than six years, responsible for sales, marketing and customer technical support, cooperating with solder paste and cleaning machine suppliers in Northern China.
