Abstract

The utility model provides a repeatedly usable circuit board, its characterized in that: the PCB comprises a PCB substrate or a universal board substrate, a guide hole with the diameter of 1.2-2 mm and a hollow copper buckle rivet with the outer diameter of 1.2-2 mm. The utility model discloses a punch on the base plate, rivet hollow copper rivet conduct the pad of circuit board. The two ends of the hollow copper rivet are curled to tightly buckle the substrate, the rivet welding disc is flat and beautiful, the welding disc is repeatedly heated during use, and the purpose of firmness, no looseness and no falling is achieved, so that the purpose of reusing the circuit board is achieved.

Description

Reusable circuit board

Technical Field

The utility model relates to a repeatedly usable circuit board mainly is applied to the real field such as real standard of the real standard of electron technology soldering, the real standard of the manual design preparation of electron technology circuit.

Background

The pad of the circuit board is generated by a copper plating process, is thin and easy to oxidize, and is easy to fall off after being heated for many times. Therefore, when the board is used, the bonding pad is basically damaged after being heated repeatedly, and the board cannot be used for the second time, so that great material waste is caused, and certain environmental pollution is brought.

Disclosure of Invention

To the defect of prior art above the ordinary omnipotent circuit board, the utility model provides a new design to reach circuit board reuse's purpose.

The purpose of the utility model is realized through the following ways:

the utility model provides a universal circuit board of repeatedly usable which characterized in that: the circuit board is composed of a PCB (or a new and old common universal board) base plate, a guide hole with the diameter of 1.2-2 mm and a hollow copper rivet with the outer diameter of 1.2-2 mm.

The circuit board substrate is made of a PCB substrate or a universal board substrate, and the thickness of the circuit board substrate is 1-2 mm.

The diameter of the circuit board guide holes is 1.2-2 mm, and the spacing between the guide holes is a multiple of 2.54 mm.

The hollow copper buckle rivet is made of copper, the outer diameter of the hollow copper buckle rivet is 1.2-2 mm, the hollow copper buckle rivet is the same as the guide hole in size, the height of the hollow copper buckle rivet is slightly larger than the thickness of the base plate and is tightly attached to the base plate, and the edge rolling width of the rivet is about 0.2-0.8 mm.

The utility model discloses quality assurance's operating method as follows:

the PCB substrate with proper thickness is selected to ensure that the PCB substrate is solid and durable in multiple use. The guide hole is suitable in space and size and is convenient for mounting elements. The hollow copper buckle rivet is used as a welding pad, the rivet is tightly riveted on the substrate during rivet installation, the curling edges at two ends of the rivet are required to tightly buckle the substrate and are smooth and attractive, and the width of the curling edge of the rivet is about 0.2-0.8 mm. The welding pad can be firm, not loose and not fall off when being heated repeatedly for welding and disassembling elements, thereby achieving the purpose of reusing the circuit board.

Detailed Description

And selecting a PCB substrate with proper thickness, and manufacturing guide holes with proper spacing and size. The rivet is arranged on the base plate, the curling edges at the two ends of the rivet are required to tightly buckle the base plate and are flat and attractive, and the width of the curling edge of the rivet is about 0.2-0.8 mm, so that the aim of reusing the universal circuit board is fulfilled.

When the circuit board is used for disassembling electronic components, because the rivet welding disc hole is relatively large and deep, more solder is hidden inside, when the soldering tin is melted, the substrate can be lightly patted to shake off the solder material or the solder is absorbed by the suction gun to quickly disassemble the element, thereby prolonging the service life of the welding disc.

The above description is a preferred embodiment of the present invention, and the present invention is not limited thereto, and any modification, equivalent replacement, and improvement made without any inventive concept shall fall within the protection scope of the claims of the present invention.
