Solder Depository Dimensioning
Brazing filler deposit sizing determines the volume of brazing filler metal to be supplied to completely fill the capillary gap and avoid dripping. This is crucial for the reliability of the brazed joint.
Physical-Chemical Mechanism of Action
Solder reservoir sizing refers to the volume of solder material to be provided, placed in a capillary gap. This gap leads to contact between the solder and the part to be joined. Correct sizing ensures the gap is completely filled, which guarantees a stable joint.
Metallurgical Relevance & Risks in Welding
Inadequate solder reservoir sizing can lead to incomplete filling of the capillary gap. This can result in missing contacts and thus poor electrical connections or even joint failure. Overfilling the gap prevents droplet formation, which could cause unwanted short circuits or contamination of the joint.
Workshop Practice & Instructions
To ensure correct solder reservoir sizing, the volume of solder material should be precisely matched to the size of the capillary gap. This can be done by measuring and comparing with standard sizes or by using special filling devices. It is important that the gap is completely filled without droplet formation.
