Standard Applications:
• Works on flip chip, chip scale package and flip chip bumping sites assemblies as a soldering flux.
• Tacky solder flux formulations are designed for pin transfer, dot dispensing and/or syringe applications.
• Tacky solder flux formulations can be used as a tack and flux vehicle for soldering components to a solid solder
deposit (SSD), or precision pad technology (PPT) board surfaces.
• Great for rework applications on all PCB packages.
• Can be used in BGA/PGA sphere/pin attachment vehicle or for repair and reballing/repinning.

Printing Parameters:
• Temperature/Humidity -- Optimal ranges for production are 21-25°C (70-77°F) and 35-65% R.H.
Activation Parameters:
• Temperature -- Optimal activation temperatures are 130°-185°C (266-365°F). See “Soak Zone”
in diagrams above.
Cleaning:
• Formula TSF-6522 is a no-clean formula. The residues do not need to be removed for typical applications.
• Although formula TSF-6522 is designed for no-clean applications, its residues can be easily removed using
automated cleaning equipment (in-line or batch) with the aid of Kester Bio-Kleen #5768 saponifier in a 10-12%
concentration in de-ionized water at approximately 140°F (60°C).
Available Packaging:
• Syringes -- 10 gram (10cc) and 30 gram (30cc) syringes available.
• Cartridges -- 150 gram and 300 gram cartridges available.
• Jars -- 50 gram and 100 gram jars available.
Storage, Handling, and Shelf Life:
• Storage & Handling -- should be kept at standard refrigeration temperatures and humidity conditions, 0-10°C
(32-50°F) and 35-55% R.H. respectively.
• Shelf life -- 4 months from date of manufacture when held at 0-10°C (32-50°F).
