Description

Integrated block connector convenient to braze

Technical Field

The utility model relates to an integrated circuit board technical field specifically is an integrated circuit board connector convenient to braze.

Background

Brazing, which is a welding method that after brazing filler metal lower than the melting point of a weldment and the weldment are heated to the melting temperature of the brazing filler metal at the same time, the liquid brazing filler metal is used for filling the gaps of solid workpieces to connect the metals. During brazing, an oxide film and oil stains on a contact surface of a base material are removed firstly, so that a capillary tube can play a role after the brazing filler metal is melted, and the wettability and the capillary fluidity of the brazing filler metal are improved. Brazing is divided into brazing and soldering according to the melting point of the brazing filler metal.

The brazing deformation is small, the joint is smooth and attractive, and the method is suitable for welding components which are precise, complex and composed of different materials, such as honeycomb structural plates, turbine blades, hard alloy cutters, printed circuit boards and the like. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and an excessively thick oxidation film, so that the assembly gap of the interface is ensured. The gap is generally required to be between 0.01 and 0.1 mm.

Compared with fusion welding, the base metal is not melted during brazing, and only the brazing filler metal is melted; compared with pressure welding, pressure is not applied to the weldment during brazing. The weld seam formed by brazing is called a braze seam. The filler metal used for brazing is called brazing filler metal.

And in the brazing process, workpieces with cleaned surfaces are assembled together in a lap joint mode, and brazing filler metal is placed near or between joint gaps. When the workpiece and the brazing filler metal are heated to a temperature slightly higher than the melting point of the brazing filler metal, the brazing filler metal is melted (the workpiece is not melted), and is sucked into and filled in gaps among the solid workpieces by virtue of capillary action, the liquid brazing filler metal and the workpiece metal are mutually diffused and dissolved, and a brazed joint is formed after condensation. However, if the heat absorption capacity of the integrated block is too large, the connecting port cannot reach the melting point and cannot be welded, so that the volume is reduced, the heat absorption capacity is reduced, and the soldering is facilitated.

Fig. 1-4 show the conventional integrated block and liquid cooling plate welding scheme, the integrated block 1 is placed on the upper portion of the liquid cooling plate 3, the welding ring 5 is placed at the welding position, and flux or soldering paste is coated between the integrated block 1 and the liquid cooling plate 3, such scheme needs the firm welding between the bottom of the integrated block 1 and the liquid cooling plate 3, in the general scheme of the integrated block type liquid cooling connecting pipe, the contact area between the integrated block 1 and the connecting pipe 2 as well as between the integrated block 1 and the liquid cooling plate 3 is large, the mass and the volume of the integrated block 1 are inevitably overlarge, so that the heat absorption amount is overlarge in the process of brazing and the welding is not firm, or the products welded in the secondary furnace are scrapped due to overburning.
