Q1: |
What are the ranges of product Omron have? |
|||||||||||||||
| A1: | Omron has several models. The top range model VT-WIN II machine is developed for post reflow/wave soldering. The VT-RBT II has two (2) versions, VT-RBT II - P (Paste) is for post printing, while VT-RBT II - S (Solder) is for post reflow/wave soldering. VT-MUS is a table-top machine for post oven. All AOI are specifically targeted for high-mixed low volume and low mixed high volume production. | |||||||||||||||
| Q2: | What is the difference between Omron AOI as compared to others? | |||||||||||||||
| A2: | Omron AOI uses patented Color Highlight technology to inspect PCB solder quality. Using this patented technology has enabled us to become the leader in solder inspection capability. Our AOI accuracy is enhanced by our Automatic Position Adjustment function which automatic adjust inspection windows when not in place due to warpage or expansion and contraction of board. This feature increases accuracy while decreasing teaching time. | |||||||||||||||
| Q3: | What is the Color Highlight technology? | |||||||||||||||
| A3: | It is a system that projects red, green and blue light sources onto the PCB at different angles. The camera captures these colors as they reflected off the board’s surface, producing a 2-dimensional image that conveys 3-dimensional information. These images allow our system to detect solder and component defects accurately. | |||||||||||||||
| Q4: | How would you positioned AOI, in-line or off-line? | |||||||||||||||
| A4: |
The decision to place it in-line or
off-line depends on few factors such as the availability of production
floor space area, the management of process flow, etc. There are,
though, advantages and disadvantages for each type.

| Q5: | How do you measures the inspection cycle time? | |||||||||||||||
| A5: | The estimated inspection cycle time is calculated through multiplying the number of frames used by the inspection rate per frame. The resolution selected will influence the number of frames for each program as a higher resolution (e.g. 50 microns) will require less frame to cover the PCB as compared to a lower resolution (e.g. 20 microns). | |||||||||||||||
| Q6: | How easy is it to develop an inspection program? | |||||||||||||||
| A6: | At the beginning, it is required of the user to create the first inspection program manually to establish the inspection library. Once it is built up, subsequent inspection program can be created by cad data conversion which takes about 15-20 minutes. | |||||||||||||||
| Q7: | How can we achieve centralized data management? | |||||||||||||||
| A7: | As our AOI utilizes the Windows environment, it can easily network with several machines at once, upload/download images and review inspection results, making centralized management of the entire line possible. The ideal platform for this would be a relational database networked with AOI machine, Repair station and Data Analysis terminals. An Oracle database is used for quick and efficient inspection data management. | |||||||||||||||
| Q8: | What is the estimated period for investment returns? | |||||||||||||||
| A8: | The investment returns varies from customer to customer. Generally, it takes about 18-24 months. | |||||||||||||||
