Conveyer belt of substrate material

Abstract

The subjective of the invention consist in providing a conveying belt for a substrate material, wherein firstly, the conveying belt prevents the shaking, S-shaped swing of the substrate material so as to avoid conveying accidents and to realize steady horizontal conveying; secondly, the conveying belt prevents the slide of the substrate material to thereby achieve the steady horizontal conveying; thirdly, the above situations are accomplished on condition that scratch, scar and damage are not led to the substrate material. The conveying belt (3) is used for a surface processing device (1) of the substrate material (A). The surface processing device (1) comprises a chemical solution trough (5) of treatment solution (B); the conveying belt (3) for conveying the substrate material within the solution in the chemical solution trough (5); a nozzle for spraying the treatment solution (B) to the substrate material (A) within the solution. The conveying belt (3) is not contacted with a circuit formation surface (D) of the substrate material (A) , end face conveying rolls (8, 9), which clamp left and right two end faces (E) along upper and lower directions to convey, are arrayed to dispose on the conveying belt (3), the end face conveying rolls (8, 9) use a straight roll (R1) and an inclined roll (R2) and perform antiskid treatment on the outer circumference thereof.

Description

technical field [0001] The invention relates to conveyor belts for substrate material. That is, the present invention relates to a conveyor belt of an end surface conveyance method of a surface treatment device used in a circuit board manufacturing process. Background technique [0002] The progress in the miniaturization and weight reduction, ultra-thinning, flexibility, multi-layering, and semiconductor packaging of circuit substrates used in electronic equipment is very significant. Similarly, the miniaturization and high-density processing of the formed electronic circuits Also significant. [0003] In addition, in the manufacturing process of such a circuit board, a surface treatment apparatus is used, and a substrate material is surface-treated with a treatment liquid such as a chemical liquid or a cleaning liquid. [0004] In such a surface treatment device, the substrate material is horizontally transported by the upper and lower transport rollers of the conveyor b...

AI Technical Summary

Problems solved by technology

[0012] That is, in this conveyor belt in the past, since the entire surface conveying rollers that sandwich and convey the entire inner and outer surfaces of the substrate material from up and down are installed in the liquid, scratches, scratches, scratches, etc. are likely to occur on the circuit formation surface of the substrate material. Damage, such as damage, causes problems in terms of reliability and yield, but this patent application intends to solve such problems (the present invention is an improved invention of this patent application)
