Solder pastes / solders

Solder pastes for reworking play an important role in the post-processing of electronic assemblies, as they ensure the quality and reliability of the rework process. Emil Otto offers a range of rework solder pastes with a variety of added values.

Rework pastes are lead-free solder pastes that are distinguished by a high level of activity as well as good wetting and spreading characteristic.

The rework pastes are mixed with halogen-free fluxing agents and are therefore perfectly suited for all kinds of manual and repair soldering. All pastes are offered in syringes with a volume of 10 g or 20 g. For manual and repair soldering the rework paste can be applied directly with the syringe, which enables a precise dosing resp. positioning of the paste. The subsequent soldering can be carried out using hot-air and soldering iron.

In individual cases, which must be checked by the user, these pastes can also support the wave soldering of critical components.

Reliable adhesion

Emil Otto solder pastes show strong adhesion before the soldering process. The components form a firm connection with the PCB during the soldering process, which is an important aspect, especially when repairing or replacing faulty components. After all, insufficient adhesion can lead to contact problems and impair the functionality of the assembly.

Efficiency

Companies need cost-effective solutions. With solder pastes that offer high performance and low application costs, the overall costs of rework can be reduced.

Optimum melting temperature

The ability of the solder paste to melt at specific temperatures is essential. A suitable melting temperature ensures that the paste melts evenly, resulting in a solid connection without damaging sensitive components. This is particularly important during rework, as existing components often need to be protected from damage.

Resistance to environmental influences

Reworking has to create durable connections that withstand thermal and mechanical stresses. High-quality soldering pastes from Emil Otto ensure stability even under demanding conditions.

Easy handling

Solder pastes from Emil Otto are easy to apply, which speeds up the post-processing. The user-friendly consistency and viscosity of the solder pastes facilitate application, especially for fine SMD components.

Flexibility in the soldering process

Since Emil Otto solder pastes are suitable for various soldering processes, they can be used flexibly in different production environments.
