Solvent Based
Cleaning medium for flux removal in semi-aqueous processes
ZESTRON FA+ is a solvent-based cleaning agent designed to remove all types of flux residues from electronic assemblies, ceramic hybrids, power electronics (power modules, leadframe-based discrete components, power LEDs) and packages (Flip Chips(CMOS). The product is characterized by its high cleaning performance and bath loading capability ensuring an extremely long bath life.
Advantages compared to other cleaners:
- High bath loading capability of ZESTRON® FA+ ensures extended bath life
- The cleaning medium does not require any specific explosion-proof environment
- Due to the surfactant-free formulation, ZESTRON® FA+ can be easily rinsed
- Increased wire bonding/molding quality for power modules, leadframe-based discrete components and Power LEDs
- Ensures a void-free underfill and improves the image resolution by removing all tacky fluxes from Flip Chips/CMOS
- ZESTRON® FA+ has been EMPF Phase II tested and MIL approved
- This cleaning medium is listed in the ESA "list of declared materials"
Water-free precision cleaning medium for flux removal
ZESTRON® VD is a solvent-based cleaning agent designed to remove flux residues from electronic assemblies, ceramic hybrids and leadframe-based discrete components in closed-loop, one chamber, vapor degreasing type systems.
Advantages compared to other cleaners:
- Due to its polar and nonpolar components, ZESTRON® VD has a wide field of application
- Completely distillable and therefore suitable for one chamber vapor degreasing processes with vacuum distillation and a vapor rinsing step
- ZESTRON® VD is surfactant-free and therefore dries residue-free
- ZESTRON® VD is particularly suitable for water-free applications, especially when rinsing with water is not an option
- Increased wire bonding/molding quality for leadframe-based discrete components due to the complete removal of flux residues from leaded solder paste
- ZESTRON® VD can also be used for stencil cleaning and in SMT printers
Precision cleaning medium for water-free Co-Solvent processes
ZESTRON® CO 150 is a solvent-based cleaning agent developed for the use in ultrasonic dip tank processes. ZESTRON® CO 150 can be used undiluted as a pre-cleaner or as a Co-solvent mixture in combination with a HFE-agent. ZESTRON® CO 150 is especially suitable for removing flux residues from leaded as well as lead-free NoClean solder pastes from electronic assemblies, power modules and leadframe-based discrete components.
Advantages compared to other cleaners:
- Good cleaning results with lead-based and lead-free solder pastes
- Increased wire bonding/molding quality for power modules and leadframe-based discrete components
- Guarantees a stable cleaning process as it minimizes boiling retarding
- Opens a broader concentration window for process controlling
- Stabilizes the cooling zone and helps to minimize the HFE consumption
- In combination with a HFE-process, ZESTRON® CO 150 enables a totally water-free cleaning process and fast residue-free drying
- Low ionic contamination values can be achieved despite the water-free process
