Problems solved by technology

Before the first article inspection is completed, the production line can only stop and wait, so the introduction of new products takes a long time, the efficiency is very low, and sometimes the delivery date may be delayed

Embodiment 1

[0027] Embodiment 1: The present invention aims at the large amount of work of online manual inspection of the first piece of SMT patch, and designs a machine that automatically completes the inspection work by a computer and has a large number of single-board components, which has a short inspection time and a high accuracy rate. The downtime and waiting time of the SMT process is saved, which is beneficial to the expansion of production capacity and the effect of improving efficiency. The invention will be described in detail below in conjunction with the diagrams.

[0028] figure 1 Shown is the flow chart of the method for checking the correctness of the SMT placement program, by sorting out the relevant data on the coordinates and angles of the relevant components collected on the circuit board; the standard format of the list (BOM) has been distinguished The bottom surface and the top surface include the component material number, component specification, and component nu...

Abstract

The invention relates to a method for inspecting SMT chip program correctness and a system thereof, comprising a method and a system for inspecting SMT chip program correctness. The invention has the advantages of effectively avoiding a large quantity of artificial on-line work carried out on the first article inspection of the SMT chip, being particularly suitable for machine types which have a plurality of veneer parts; due to the off-line inspection work automatically finished by a computer, having short inspecting time and high correctness ratio; saving waiting time of machine halt of SMT working procedures in the flow and thus being beneficial to expanding productivity and upgrading benefit; improving the leading-in speed of new products and meeting the requirements of client shipment time to the maximum extent.

Description

technical field [0001] The present invention relates to the process flow of Surface Mount Technology (SMT for short), and more specifically, relates to a method and system for checking the correctness of the SMT patch program in the SMT process flow. Background technique [0002] With the development of circuit boards in the direction of high precision and high density, SMT components are getting smaller and smaller, and there are more and more components on the circuit board. Not uncommon. If the SMT placement program is programmed incorrectly, a large number of defective products will be produced, which will not only increase the cost of rework, but may also lead to scrapping. Therefore, when the first single board is processed by SMT, the first article inspection is required. The first article inspection is to check the correctness of the physical patch components against the bill of materials (BOM). For resistors, capacitors, inductors, etc. Components need to be remov...
