ph Neutral Cleaning Agents - Market Expectation & Field Performance

Feb 25, 2016 | Umut Tosun, Jigar Patel, Kalyan Nukula, Fernando Gazcon, ZESTRON America

With regard to precision cleaning applications within electronics manufacturing, pH neutral product development was a major breakthrough in recent years. The impetus for this development resulted from changes with regard to solder paste formulations and resulting assembly processes.

The greater use of lead-free solder paste and the required higher reflow profiles have resulted in even more difficult to remove burnt-in flux residues. Coupled with increases in component density, larger component packages, higher lead counts, finer lead spacing, and lower standoff distances, effective cleaning is greatly challenged. The aqueous alkaline based cleaning agents can effectively remove these flux residues, however, the process often requires an increase in wash temperature and exposure time, chemical concentration, and mechanical energy. Although an efficient and effective cleaning process can be developed, oftentimes, the required operating parameters present a new set of challenges with regard to material compatibility.

Since their introduction, the newly developed pH neutral formulations have proven to be capable not only of removing these difficult post reflow residues from complex board geometries, but do so without affecting material compatibility of sensitive components. Additionally, they perform at low concentration levels. This study reviews the performance of pH neutral cleaning agents as compared to alkaline cleaning agent alternatives and includes field data demonstrating their effectiveness with regard to material compatibility and cleaning performance....

Why Switch From Pure DI-Water to Chemistry

Dec 22, 2009 | Dr. Harald Wack, Umut Tosun, M.S.Chem.Eng., Dr. Joachim Becht, Dr. Helmut Schweigart

While most cleaning applications in the North American market rely on cleaning with DI-water only, for removing OA fluxes in first place, recent market studies show that water has reached its limitations in cleaning performance while favoring usage of aqueous processes. The term aqueous implies the use of aqueous-based chemistries with active ingredients and are usually diluted with DI-water. The nature of these active ingredients in the aqueous chemistries varies between manufacturer and his R&D knowledge. ...

Fluid Flow Mechanics Key To Low Standoff Cleaning

Sep 18, 2009 | Harald Wack, Ph.D., Umut Tosun, Naveen Ravindran, Sylvain Chamousset, Joachim Becht, Ph.D.; ZESTRON, Steve Stach, Austin American Technology Corp.

In recent years, various studies have been issued on cleaning under low standoff components; most however, with incomplete information. It is essential to revisit and describe the latest challenges in the market, identifying obvious gaps in available information. Such information is crucial for potential and existing users to fully address the cleanliness levels under their respective components. With the emergence of lead-free soldering and even smaller components, new challenges have arisen including cleaning in gaps of less than 1-mil....

Thermal Residue Fingerprinting: A Revolutionary Approach to Develop a Selective Cleaning Solution

Jul 01, 2009 | Steve Stach, Austin American Technology Harald Wack, Ph.D., Umut Tosun, Naveen Ravindran, ZESTRON America, John M. Radman, Daniel D. Phillips, Trace Laboratories East

During the last 5 years, the processes to remove flux residues especially for lead-free and challenging geometries have demonstrated new cleaning obstacles which have to be overcome.i A new methodology has been recently developed to further increase the propensity for successful cleaning.ii At the core of this method is the thermal identification of the residue matrix. Thermal energy changes the physical state, i.e. transitions between liquid, solid and gas phases. By taking advantage of such specific information during phase transitions, the cleaning process can be tailored to such settings, which in turn increases the cleaning success significantly....

Cleaning High-power Electronics

Jan 06, 2009 | Steve Stach, Austin America; Harald Wack, Ph.D., Naveen Ravindran, Zestron America; Joachim Becht, Zestron Europe

To prevent malfunctions in high-power electronics, flux residues must be removed from flip chip components prior to subsequent processes. As a result, integrating a suitable cleaning application into the manufacturing process of flip chip components is often required. Solvent based applications have re-emerged, and with that, an overall process solution is necessary....
