7. SPC data statistics, the same error occurs many times automatic alarm, so as to remind the improved production process.
1. According to the detection principle, AOI visual inspection equipment can be divided into two categories: one uses laser as detection means, the other uses CCD lens to capture images for processing. In the AOI products using CCD mode, the vast majority still use black-and-white image processing mode. Another way to realize three-dimensional is to use color principle combined with color CCD lens to process the assembly board in "color highlight" mode.
2. AOI visual inspection is divided into two parts: optical part and image processing part.
3. AOI visual inspection equipment can be placed at different positions of SMT production line after solder paste printing, before reflow soldering and after soldering.
4. AOI visual inspection equipment is placed after solder paste printing to detect the following contents: too much solder paste, too little solder paste, whether the position of solder paste graphics is offset, whether there is adhesion between solder paste graphics.
5. AOI visual inspection equipment is placed after SMT mounting, and the inspection contents before reflow soldering are as follows: component sticking error, displacement, reverse sticking (such as resistance flip), component side standing, component loss, polarity error, sticking between solder paste patterns caused by excessive chip pressure, etc.
6. AOI visual inspection equipment is placed after reflow soldering furnace. The inspection content: it can detect the welding defects such as wrong component placement, component displacement, component reverse placement (such as resistance turnover), component loss, polarity error, solder joint humidity, too much solder, too little solder, missed solder, false solder, bridging, solder ball (solder ball between pins), component warping (vertical stele).
7. AOI visual inspection equipment can detect the types of welding defects: missing parts, reverse polarity, reverse component turnover, OCR character recognition, nosolder lack of tin. / multi tin, bridge bridging, shift offset, other.
1 . Flexible line change, suitable for testing product variety, small single quantity, often need line change.
2. It is suitable for off-line inspection after reflow welding and wave soldering.
