MAX II - Heated. Underfill with Jetting Pump NCM5000
The GPD Global® MAX II Series is a compact; high-accuracy system designed for today’s advanced heated dispensing applications. The frame is molded from “liquid rock” which gives the system a stable platform for accurate, reliable, high-speed, and long term production. MAX II systems are available in either stand-alone or inline configurations.
Substrate heating methods are either:
Convection/Forced Air - heat is transferred to the product via an air stream from below the board. This method is preferred when the bottom side of the product has features that are difficult to compensate for with contact fixturing.
Contact - Heat is rapidly transferred to the product through direct contact with the product. In most cases, the fixture incorporates vacuum to pull the product to the heated surface for uniform heat transfer.
Stand-alone, heated worktables function the same as non-heated worktables, but have heat built into the plate. Maximum heat on the worktable surface is 200 degrees C. Forced air may be incorporated into the worktable. In this case, raised rails are put on the worktable to allow air to evenly contact the bottom of the substrate.
The worktable may also incorporate vacuum to hold the product during processing. Vacuum holes are positioned in a 1" matrix over the entire worktable. Plugs at each of the locations may be removed to apply localized vacuum. In instances where the locations of these vacuum ports may not suit the product, a custom overlay may be placed on the worktable to apply vacuum where needed.
When heating is required for inline applications, the system is configured with a 3-zone conveyor and heat at each of the locations. Heating at all 3 zones makes for a complete process.
Pre-heat: Preheating is used to bring the product up to operating temperature. More aggressive heating may be applied to this zone to decrease the time required to bring the product up to temperature.
Work Area Heat: Work area heating is used to normalize the heat on the substrate. Heat in this zone is typically applied via a contact vacuum fixture for the most uniform transfer of heat.
Post-Heat: Post heating is typically used to keep the product at temperature and to continue fluid flow. Heating may be either forced air or contact fixturing.

When dispensing fluids, there is always a question about the consistency of the fluid delivered to the pump. Different fluid materials, batches, and levels in the syringe or reservoir can affect flow when fluid is fed from a syringe.
Fluid Pressure Control (FPC) is a breakthrough in uniform fluid dispensing. FPC ensures a constant supply of fluid is always available to the pump regardless of reservoir size or fluid level. FPC provides a consistent feed of fluid to the dispensing pump regardless of reservoir fluid level. FPC monitors the pressure of fluid entering the dispense pump and makes adjustments to the reservoir feed pressure, resulting in a consistent feed to the dispense pump
FPC is available in all GPD Global dispense platforms. An offline control system is available to interface with your existing dispense pump. Contact GPD Global +1(970)-245-0408 for details.
