A mature SPI equipment, 3D solder paste detection machine introduction
J6800 SPI features:
1.DLP double-sided light source digital projection measurement technology
★ Using four-phase displacement calculus, the special light source and algorithm can accurately detect the solder paste printing, such as offset, tin much, tin less, short circuit, foreign matter, tip and so on.
2. Stop-and-go FOV photography
★ When testing, do not sample when moving, and do not move when sampling. The influence of vibration on detection is minimized, and the test is stable and reliable.
3. Higher test accuracy
★ Accuracy of 5um,10um,15um three options, the minimum can be tested 03015 points. Not fussy about PCB bottom plate color
4. Statistical analysis reveals the trend change
★SPC performs statistical analysis and comparison of test results, graphically provides trend distribution and various analysis chart reports. X-chart, Xbar-chart, CPK, GRR, Ca, Cp, process capability chart
5. The passing rate of AOI in the later section becomes higher
Because the bad solder paste printing is blocked by SPI detection, eliminating the main bad source, the pass rate of the later AOI will naturally rise
6. Save human resources
★ After importing J6800, it can realize multi-machine control and save personnel allocation. Reduce labor costs
J6800 SPI architecture:
★★ Use Texas Instruments DMD chip
The generation of traditional fringe light is driven by the form of grating, and the digital fringe light projected by the DMD chip in the J6800 can achieve the high-speed transformation of fringe
★★ Improves stripe light contrast
DMD chip is a full reflective mirror group. It can improve the contrast of fringe light. DMD can accurately divide fringe into reflection and non-reflection. There is no intermediate value of grating, and the precision of fringe will directly determine the accuracy of measurement
★★ Improve the detection speed
Compared with the grating and DLP projection,DLP improves the speed of each fringe transformation. Each conversion takes only 3 milliseconds. For testing, the required testing time will be greatly reduced
★★ Industrial camera
Industrial-grade high-speed cameras have stable and fast images
★★ Telecentric lens
The image is clear without deformation, the problem of bending and warping is overcome, and the test is more accurate
★★ Left and right bilateral digital fringe measurement light source
No shadow interference, improve measurement accuracy, more stable test.
★★R+G+B color low light panel
Color image analysis, accurately distinguish solder paste, pad, bottom plate, screen printing, eliminate interference
★★ Coaxial light source
1, The J6800 combines the world's fastest SPI speed with precision
2, Stop-and-go static image taking
3, Various plate color problems are easily solved
The color filter function is used to extract the desired color, filter it, remove the interference, and make the calculation precision higher.
- Bottom plate: exclude the influence of different color plates.
- Copper foil: eliminate the impact of pad noise
- Solder paste: Filter out the part that needs to be calculated and calculate the short circuit.
- White paint: Remove the interference of screen printing on the PCB
