The testing equipment in the SMT factory is very important, the testing equipment will be directly related to the quality of the shipped products, and the excellent quality testing equipment can find the products with quality problems in the processing process and solve them in time. What testing equipment is needed in the production process of SMT chip processing?The following professional SMT factory Juchuan Electronics (www.).smtworks.com.cn) to give you a brief introduction.
Common testing equipment in SMT factories are:
1）spi2）aoi
3）x-ray
4) ICT I. SPI testing.
SPI (Solder Paste Detector) is generally placed after the solder paste printing process in SMT chip processing, and is mainly used to detect the thickness, area, and offset of solder paste on the circuit board, and is an important equipment for monitoring the printing quality of solder paste.
2. AOI detection.
AOI (optical detector) is placed in many positions in SMT factories, but it is generally placed behind reflow soldering in actual processing, which is used to inspect the welding quality of PCBA after reflow soldering, so as to find and eliminate defects such as less tin, less material, virtual soldering, and tinning in time.
3. X-ray detection.
X-ray is actually a common X-ray in hospitals, which uses high-voltage impact on the target to produce X-ray penetration to detect the internal structure of electronic components, semiconductor packaging products, and the quality of SMT various types of solder joint welding. X-ray detects all solder joints on the board, including those that are not visible to the naked eye, such as BGA. In addition, the defects that can be detected by the X-ray detector are mainly defects such as bridging, voids, too large solder joints, and too small solder joints after welding.
4. ICT testing.
ICT is oriented to the control of production processes and can measure resistances, capacitors, inductors, and integrated circuits. It is particularly effective for detecting open circuits, short circuits, component damage, etc., with accurate fault location and convenient maintenance. It can test problems such as false soldering, open circuit, short circuit, component failure, and wrong material after welding.
