Obtaining the correct amount of solder to ensure a strong solder joint is critical in electronics manufacturing. However, miniaturization trends, such as the reduction of stencil thickness and more tightly fitted components make this increasingly difficult. Solder Fortification Preforms can provide the solution for these challenging issues.

Solder Fortification Preforms are generally rectangle shaped pieces of alloyed metal that do not contain any flux. The preform is added to a deposit of solder paste using standard pick and place equipment. Since the alloy for both the preform and the solder paste are the same, the preform will reflow at the same temperature as the solder paste, with the solder paste providing the necessary flux. The preform increases the volume of solder above what could be achieved with just solder paste, especially for stencils with a pitch of 0.3mm or less.

Features

• Increased solder volume

• Improved drop test results

• Fewer issues with flux residue

• Reduced rework

• Improved fillet shape and volume

Advantages

The advantages of Solder Fortification Preforms include:

• Increased solder volume above what could be accomplished with just solder paste

• Fewer issues with flux residue

• Elimination of costly or time-consuming processes, such as wave soldering or selective soldering

• Stronger solder joints which help improve drop test results

• Reduced rework and other manual processes to add solder volume

• Improved shape and volume of fillet to ensure joints meet IPC specifications

Packaging

Solder Fortification Preforms are packaged in tape & reel for easy placement by standard pick and place machines.
