An LED backlight strip can have dozens of lens positions on a single board. The F12 is a PCB jet dispensing machine listed for applying adhesive at those repeated positions before lens placement. The jet valve ejects deposits without touching the board at each point. The deposit must land where the lens seats and stay clear of the optical area and neighboring features.
Main application | LED lens bonding on TV backlight strips |
|---|---|
Dispensing method | Non-contact jet dispensing |
Sample details | Adhesive grade, target dot size and panel layout |
Adhesive and panel layout
A useful sample uses the same adhesive and surface finish as production. Share the material grade, target dot diameter or volume and the time between dispensing and lens placement. Check for satellite droplets and spreading on the actual strip, especially at small lens footprints. For long strips or several strips in one panel, include the fiducial layout and any panel bow you expect so the valve setup and board support can be reviewed together.
If you are quoting the F12 for another PCB adhesive process, send a drawing showing each deposit and the clearances around it. GEEKVALUE can review the valve and material feed requirements against that pattern. Include your panels-per-hour target so the review can account for alignment and board handling as well as the dispensing sequence.
