Description

Improve tool of wave soldering bridging

Technical Field

The utility model belongs to the technical field of PCB (printed circuit board), and particularly relates to a jig for improving wave soldering bridging.

Background

The electronic circuit board is an important electronic component, is a support body of the electronic component, and is a carrier for the electronic component and the electrical interconnection;

wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of soldering, the high-temperature liquid tin keeps an inclined plane, and the liquid tin forms a wave-like phenomenon by a special device, so that the wave soldering is called wave soldering, and the main material is soldering tin bars;

the existing wave soldering jig for the PCB is a common wave soldering jig, one is made of rectangular synthetic stone material, and is cut into a plurality of holes to bear PCBA plug-in components and then subjected to wave soldering;

because the pins of part of the material pieces are subjected to 100% bridging after being densely welded through wave soldering, the quality of products is affected, the maintenance cost is increased, the labor cost is reduced, the efficiency is low, the yield is low, and the welding quality is not guaranteed sufficiently.

In order to solve the above problems, a jig for improving wave soldering bridging is provided in the present application.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides a jig for improving wave soldering bridging, which has the characteristics of improving production efficiency, reducing reject rate and rejection rate and reducing labor cost.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an improve tool that wave soldering bridged, includes the stove carrier that crosses, it has the circuit board mould to cross the shaping on the stove carrier, still install the setting element on the stove carrier to cross, set up flutedly on the circuit board mould, be fixed with the copper sheet on the circuit board mould.

As a preferred technical scheme of the jig for improving wave soldering bridging, the groove is formed in the circuit board die, and the copper sheet is arranged on the circuit board die.

As a preferred technical scheme of the jig for improving wave soldering bridging, a step-shaped structure is formed between the groove and the copper sheet.

As a preferred technical scheme of the jig for improving wave soldering bridging, the copper sheet is also positioned at the dense feet of the circuit board.

Compared with the prior art, the utility model has the beneficial effects that: the purpose of the groove is to increase the gradient of the bottom tin support of the jig when the flat wave and the sharp wave of wave soldering reach the same plane with the bottom of the jig, so that the redundant tin dissolution at the periphery of the soldering point and the soldering position can be rapidly taken away. Similarly, copper sheets are added at the welding points at the bottom of the jig for interval purposes, when flat waves and sharp waves of wave soldering reach a plane with the bottom of the jig, after tin coating on the welding points is completed, redundant tin is taken away, so that the welding is ensured not to be bridged; by adding the copper sheet on the wave soldering jig, the extra tin is taken away when the wave soldering is performed, so that the bridging problem is effectively solved, the product quality is improved, the operation efficiency is higher, and the quality is ensured.
