Embodiment Construction

[0025] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0026] The present invention establishes a plane carrier model during PCB layout and wiring for the PCB with double-sided solder paste carrier passing through the soldering furnace, and presents the carrier model in an intuitive manner as a reference for the PCB carrier manufacturing process to ensure that the layout and wiring are completed The PCB becomes a practical and effective PCB design. The invention is suitable for electronic and electrical products that perform the PCB carrier wave soldering process. As long as the pre-designed PCB adopts the carrier wave soldering process, the design of the PCB carrier model is applicable to the present invention. The following takes the PCB of a certain electronic product as an example for specific instructions:

[0027] First, establish a model of the plane carrier during PCB layout, such as figure 1 Shown is th...

Abstract

The invention discloses a layout wiring method for a simple tin stove carrier model of a printed circuit board. Aiming at the printed circuit board (PCB) employing a carrier wave soldering tin stove process, a simulated carrier model is built during a PCB layout wiring process; through analysis on the carrier model, the PCB is inspected and timely corrected, so that the designed PCB meets a later processing technology of the carrier wave soldering tin stove; the poor phenomenon of a failure of the designed PCB due to the fact that the carrier corresponding to the PCB cannot be designed, or missing solder after the PCB is matched with the corresponding carrier tin stove is avoided; and the product development schedule is quickened.

Description

Technical field [0001] The invention is suitable for the layout and wiring design of various electronic and electrical products that require PCB carrier wave soldering and tin furnace processing technology, and belongs to the field of electronic technology. Background technique [0002] PCB, the full English name is PrintedCircuitBoard, that is, printed circuit board, or printed board for short, which is one of the important parts of the electronics industry. For PCBlayout (layout and routing) engineers, it is not only to realize the physical connection of electronic products by way of wiring, but also to consider that the designed PCB meets the process requirements of post-processing, such as the welding process of components. Operational. [0003] In the current design of electronic and electrical products, two-layer or multi-layer PCBs are often used. There are SMD devices on the top and bottom layers, and there are plug-in devices on the top layer. The manufacturing process (w...
