SMT outsourcing development has been a common processing mode in the SMT chip processing industry, many traditional pure processing SMT factories have begun to integrate upstream and downstream resources to provide one-stop electronic processing services, such as: component procurement, PCB board, SMT pick and place machine processing, DIP plug-in processing, post-soldering, assembly and testing, aging, three-proof and other services. In the SMT package production and processing there are usually many kinds of quality inspection means to provide customers with qualified products, AOI machine inspection is one of them. The following NeoDen give you a brief introduction to the AOI inspection process.
I. By using the optical principle so that the camera on the equipment automatically scan the PCB, capture the image, and then the collected SMT SMD processing of solder joint data and the machine database of qualified data for comparison, and then after image processing, marking the board welding.
II. With the development of electronic products toward miniaturization, the circuit board is also more and more to precision, relying solely on manual visual inspection of the SMT SMD solder joints to check the difficulty is also increasing, long time to check, easy to produce eye fatigue and caused by leakage, this time AOI can reflect its superiority, the main advantages are as follows:
1. Save manpower and reduce labor costs.
2. Improve production efficiency and production capacity.
3. Improve the qualified rate of warehousing.
4. The collection of inspection data, provide process analysis, strengthen the process capability.
5. Uniform testing standards, not because of line differences.
6. Able to timely feedback and statistics on production problems.
III. Location
1. SMT SMD processing is completed after the use of: can effectively prevent the lack of components, polarity, displacement, monument, reverse and other issues.
2. Used after reflow oven: at the end of the production line, the detection system can effectively check out the PSMT processing of missing components, offset, skewed and other issues, the correctness of the solder joints and the amount of tin there is no shortage of solder, welding short circuits, warped feet and other defects.
