Method and system for creating B side and T side detailed list of veneer

Abstract

The invention relates to a method for generating single-plate B surface and T surface bill, which comprises: a, reading the single-plate globe bill and position number bill; b, based on the position number of globe bill, writing the B surface or T surface information of position number of position number bill document into bill data list; c, using said bill data list to generate B surface bill and T surface bill. The invention can shorten the SMI processing time and improve the efficiency, to reduce the possession on SMT machine and FEEDER resource.

Description

technical field [0001] The present invention relates to a surface mount technology (Surface Mount Technology, referred to as SMT) process flow, more specifically, relates to a method and system for generating a list of B-side and T-side of a single board in the SMT process flow. Background technique [0002] With the development of high-precision and high-density circuit boards, there are more and more devices on the circuit board, so most of the circuit boards adopt the method of double-sided device processing, that is, the B side of the circuit board (BOTTOM side) and the T surface (TOP surface) patch processing. [0003] At present, in the SMT processing flow, the complete list of the single board produced generally does not generate the B-side SMT list and the T-side SMT list, but a complete set of all devices, as shown in Figure 1. [0004] Since the single board complete list does not generate the B side and T side, if the single board complete list is used for SMT pr...

Problems solved by technology

[0007] However, there are many problems in making the B-side list and T-side list separately, resulting in low efficiency and error-prone. First, it will cause unclear responsibilities and increase workload

Because in general, the complete list of single boards is prepared by the circuit diagram designer, but whether the bit number is B side or T side is determined by the PCB designer. The circuit diagram designer and the PCB designer are generally not the same person. Both the B-side list and the T-side list, whether it is the responsibility of the circuit diagram designer or the PCB designer, require a lot of communication and confirmation work, resulting in increased workload and error-prone

[0008] In addition, the B-side list and T-side list are made separately, and the planning business also increases the workload and difficulty of planning. Due to the increase in the list level, the planning business needs to issue task orders and plan forecast summaries for multi-level lists, which increases the workload. Not conducive to BOM flat design

[0009] Furthermore, if the B-side list and T-side list are made separately, for processing companies that have already used the complete list in large numbers, it is still necessary to clean up the old list, which is a huge workload and prone to errors

At the same time, it also has an impact on the habitual operation of other links, and it is also prone to errors
