Embodiment Construction

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

[0026] The present invention aims at the PCB with the double-sided solder paste carrier passing through the tin furnace, establishes a plane carrier model during PCB layout and wiring, presents the carrier model in an intuitive way, and serves as a reference for the PCB carrier manufacturing process to ensure that the layout and wiring are completed The PCB becomes an actual valid PCB design. The present invention is applicable to electrical and electronic products that carry out PCB carrier wave soldering and tin furnace process. As long as the pre-designed PCB adopts carrier wave soldering process in the later stage, the design of its PCB carrier model is applicable to the present invention. The following takes the PCB of an electronic product as an example for specific instructions:

[0027] First, establish a model of the plane carrier ...

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 applicable to the layout and wiring design of various electronic and electrical products that need to use the process technology of PCB carrier wave soldering and tin furnace, and belongs to the field of electronic technology. Background technique [0002] PCB, the English full name is Printed Circuit Board, that is, printed circuit board, referred to as printed board, is one of the important components of the electronics industry. For PCB layout (layout and wiring) engineers, it is not only to realize the physical connection of electronic products in the form of circuit wiring, but also to consider that the designed PCB meets the process requirements of post-processing, such as the welding process of components. Operability. [0003] In the current design of electronic and electrical products, two-layer or multi-layer PCBs are often used. There are patch devices on the top and bottom layers, and plug-in devices on the top layer. Div...
