TROI
More than 50% of defects are from screen printing process
Fast & AccurateFast & Accurate
In spite of the importance of the color image in the apparatus for measurement of the surface profile, the color camera has defects of being high in price and being low in capture speed rather than the black and white camera.
TROI systems are equipped with 4MP Black & White camera due to;
1.Faster Inspection Speed2.Higher Accuracy compare to Color Camera3.Competitive price for end users

Combination of 2D & 3D inspection eliminates common Shadow problem with SPI systems.
Camera grabs shapes of solder from simultaneous 2D and 3D LED light source.
Not only Dual Projection,2D LED approve to be recognized the exact solder field

Inspection Logic -2D & 3D Phase Shifting Technology
2D camera detects “Zero reference point” and inspects solder shape like smearing simultaneously.
Solder lands are higher or lower than PCB surface. Pemtron Phase Shifting technologies measure the height and volume deposition from the surface of the lands. Also SPI inspects the solder deposition shape.

TROI SPI automatically recognizes all traces, silk print and land height in order to perform accurate inspection by scanning bare board in about 60 seconds.SPI measures the accurate solder height and volume by compensating traces and silk height, beside most of other systems are using PCB surface as “Zero reference point”
Captured image without bareboard teachingHeight Result = 164 um
Captured image with bareboard teachingHeight Result = 140 um

Inspection
Competitor’s models used the method which could only recognize solder higher than 40um, making it impossible for measurements below 40um height level.
Pemtron has solved this problem by using an Enhanced 3D Color Algorithm that can defines solder printed from a 0 reference point.
Accurate Inspection by 2D Color Algorithm
Advanced Accuracy & Advanced Accuracy & Reliability by 3D AlgorithmReliability by 3D Algorithm
Color 3D Algorithm can inspect from the bottom of PCB ,therefore PEMTRON can inspect the accurate PCB bottom, such as Hole, silk.
In conclusion, this 3D Algorithm makes it possible to find the exact solder field.

Color DistributionColor Distribution
Height of solder deposition is higher on left side of array
User changed pressure on printer todistribute solder evenly
Color Map View is capable to show the solder deposition data by Height, Volume & Area. It is easier to see the deposition condition and helps engineers tocheck screen printing ability.
Glue InspectionGlue Inspection
Combination of various LED makes possible to inspect glue (adhesive) on PCB.
Golden Finger Inspection (2D)Golden Finger Inspection (2D)
The system can detect solder splash on the golden finger. The minimum size of splash detection (18um resolution) is 50um in diameter. About 3 particle of solders are about 50um. 12um resolution system can detect as small as 40um of splash size.

SPI Monitoring System - Production Lines.
• Monitoring Production(Inspection) Status for entire Lines(SPI)
• CP/CPK/Histogram/Sigma/Yield/Defect type/Report
• Remote Control system
You can monitor multiple lines in from management server (extracted from RMC)
SPI Monitoring System - Production Lines.
• You can monitor production status based on CPK chart • Each board information will be saved and can check the board information • If some problem happens in out of CPK range,
user can leave the comment about the issue by user
