Defect Verification & Repair System VT-1850

Defect Verification & Repair System VT-1850

The VT-1850 is a defect verification and repair system with a 12x optical zoom lens designed for use with high-precision patterns. It can be connected with the PI-9700 and MI-9700 and also provides straightforward defect checks for high-precision patterns and blocked holes on PCBs and photomasks. The VT-1850 can also be linked with Sentflow, enabling the creation of precise defect trend maps and provision of feedback when
redundant defects occur.

Features

  1. Package PCB inspection function

    This system greatly enhances verification of multiple-piece PCBs such as IC package substrates. When the number of scrapped or faulty pieces in a sheet reaches a specified amount, verification on the sheet can be automatically skipped. Verification of scrapped pieces and sheets on other layers can also be automatically skipped.

  2. High-level measurement function

    The VT-1850 is equipped with a proprietary image processing engine developed by Dainippon Screen. It is capable of accurately recognizing the edges of wiring patterns and, as evidenced by the measurement of the impedance coupon, pinpoint accuracy is possible. The VT-1850 is also able to acquire measurement point data based on the original design data when an instruction is received from the CU-9000.

AOI setup system「EzPrex」

Faster pre-inspection setup without specialized skills


The EzPreX is installed as a standard function, enabling the rapid and automatic setting of optimal values for thickness, alignment, threshold and other parameters. The EzPreX uses a proprietary algorithm to achieve extremely quick and accurate setup. The EzTune is also available, allowing the operator to perform final adjustment while viewing the screen. Used together, these functions greatly reduce operator workload.

 

Hardware-less Verification System「iSift」

Post-inspection verification of defects can be performed using a network PC. Defect images are displayed as thumbnails in real-time starting with scanned areas, allowing them to be efficiently assessed and classified as accepted or rejected using the mouse. Using this system to sort defects before starting verification in VT series equipment significantly improves processing efficiency and shortens the verification time.
