MECHANIC EF-820 - Special BGA Soldering Flux (20ml)

Description

The MECHANIC EF-820 is a high-precision soldering flux, specifically formulated for critical interventions on BGA (Ball Grid Array) components. Whether you are in the desoldering phase, cleaning pads or reballing processors (CPU), the EF-820 guarantees optimal thermal conductivity and flawless tin fusion. Its fluid texture penetrates effortlessly under the densest chips, ensuring even heat distribution and bright, robust solder joints.

Thanks to its No-Clean technology, this flux does not leave sticky or corrosive residues that could alter the performance of high-frequency circuits. It is particularly appreciated for repairing smartphone motherboards (iPhone, Samsung) where component density is extreme. The EF-820 significantly reduces the risk of "dry joints" or accidental bridges, making it the indispensable ally for any technician specialising in advanced micro-soldering.

Workshop Advice & Usage

For perfect reballing with the MECHANIC EF-820, apply a micro-drop to the four corners of the chip before positioning it. Capillarity will do the rest during the temperature rise. Pro tip: If you are using this flux to remove glue (underfill), let it heat slightly so that it softens the residues before using your cleaning blade. Although "No-Clean", a quick wipe with isopropanol alcohol after final soldering will allow you to inspect your solder balls more clearly under the microscope.
