Water-Soluble Solder Paste

Water-Soluble Solder Paste

Product Description

Kester R562 is an organic acid, water-soluble
solder paste specifically designed for resistance to
environmental extremes. Water-soluble pastes
tend to dry out in low relative humidity and slump
at high relative humidity. R562 will maintain its
print characteristics, tack and activity even after
exposure to environmental extremes.

• Reduces BGA voiding to <3%

• Bright, shiny joints
• 12 hour stencil life
• Print speeds up to 6 in/sec
• Compatible with enclosed print head systems
• Capable of multiple reflow profiles before a

cleaning operation is required

• Consistent printing over a range of temper-

atures and humidity

• Excellent solderability to a wide variety of

metallizations, including Palladium

• Residues easily removed with hot DI water,

even up to 96 hours after processing

• Classified as ORH0 per J-STD-004
