Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0031] refer to figure 1 , an SMT production intelligent error-proof traceability method and process, comprising the following steps:
[0032] S1. Incoming material inspection: First, take stock of the quantity of materials, conduct a preliminary inspection of the appearance of the materials, and check whether there are damages or scratches;
[0033] S2. Material information maintenance: check the material information, obtain the material specification model, production date, production batch, brand, etc., enter the work order number in the system to bring up the material loading record form;
[0034] S3. Material binding: Bind the material tray information, bind th...

Abstract
The invention discloses an intelligent SMT production error-proof tracing method and process, which comprises the following steps: incoming material inspection, material information maintenance, material binding, putaway and warehousing, work order filling, BOM introduction, material issuance according to BOM work order, PCB work order binding, PCB scanning identification, SMT printing, SPI detection, PCB scanning, SMT patching, reflow soldering, AOI optical inspection, NG visual inspection, insert welding, insert quality inspection, flying probe testing, packaging and shipping. The tracing method and process use the intelligent manufacturing production method on the basis of the conventional production process method to ensure the traceability of the product. After the production of the product, the flying probe test is added to perform the functional test to inspect the product reliability, so that the qualified rate is controlled from the source, the ex factory qualified rate is greatly improved, the customer satisfaction rate is improved, the repair rate is reduced correspondingly, and costs are reduced.
Description
technical field [0001] The invention relates to the technical field of surface assembly technology, in particular to an intelligent error-proofing traceability method and process for SMT production. Background technique [0002] With the development of science and technology, electronic manufacturing technology is advancing by leaps and bounds, and the SMT industry is the link of the industrial chain, and equipment technology updates are also changing with each passing day. In today's era of pursuing energy efficiency, high efficiency has become the core goal of an enterprise, which makes us abandon The old thinking in the past is no longer blindly pursuing output, but more and more pursuing quality. In the pursuit of high quality, good equipment is of course essential, but good craftsmanship is the icing on the cake. [0003] Conventional SMT production process in sequence: incoming material inspection--material incoming storage--BOM manual picking--material output--printi...
