[Manassas, VA – September 13, 2016] - ZESTRON, the global leading provider of high precision cleaning products, services and training solutions in the electronics manufacturing and semiconductor industries, is pleased to announce that Jigar Patel, M.S.Ch.E., Senior Application Engineer, ZESTRON Americas, will present “Evaluating Rinsing Effectiveness in Spray-in-Air Cleaners” at SMTA International 2016.
Spray-in-air systems include wash, rinse and dry cycles. Engineered cleaning agents are critical to the process. Given the low standoff heights of components on present day PCBs, low surface tension is required to enable the cleaning agent to penetrate underneath components to contact and solubilize the residue. The rinse cycle is critical to the process for the rinse water must penetrate the same low standoff components in order to remove the residue laden cleaning agent. However, rinsing uses pure DI-water. Given the surface tension of water, how effective is this process? This study was designed to investigate the efficiency of the rinse cycle using both a spray-in-air batch and inline cleaner. Test vehicles used were affixed with glass slides at various standoff heights to represent low standoff components.
Mr. Patel’s presentation will be on Thursday, September 29th, during session MFX8 – Cleaning: Low Clearance Challenges. To register for this event, please visit SMTA.org.
