ITW EAE – Camalot – Prodigy
The Camalot Prodigy dispenser is designed and built to deliver high-speed, extremely accurate dispensing. To enable 1.5g’s of acceleration, Camalot engineers resourced more than two decades of experience with linear motors and advanced motion control systems.
Easy to learn and use, ITW EAE’s Benchmark software is powerful yet intuitive, and offers enhanced functionality and features such as a flip chip calculator for underfill. It outputs accurate volume and weight details by allowing precise weight data to be entered into the program, reducing setup time and scrapped parts.
High-Speed and Extremely Accurate Dispensing
Advanced linear-drive architecture, combined with exceptional frame stability enables greater precision at higher speeds, resulting in consistently higher yields. The Camalot Prodigy boasts a +/- 35µ 3 Sigma dot placement accuracy at full speed.
Large Board Capability
Innovative board staging option can double or even triple the dispense area in the X direction, allowing product of >900mm to be processed.
Controlled Heating for a Repeatable Process
Contact and non-contact heating in several configurations including heated lift chucks ensures that dispense materials are at a controlled, constant temperature for repeatable, controllable material flow rates for underfill and encapsulation.
Plug and Play Architecture
Constantly changing needs in dispense processing require flexibility in system configuration. The Prodigy’s features are easily field upgraded, due to ‘plug and play’ compatibility and simplicity. They can be retrofitted in the field, including heat, pumps, weight scale, 2nd Z-axis, and even the conveyor system.
Independent Dual Head
Independent Dual Head configurability allows dispensing of different materials within one process. Both Z-axes are independently controlled, facilitating both high positional accuracy and fast axis movement.
Synchronous Dual Head Mode
Synchronous Dual Head Mode operates both pumps simultaneously and reduces dispense time by approximately 50%.
Automatic Vision Alignment
The Prodigy features automatic vision for both fiducial alignment and manual teaching of programs. Fiducial images are taught and saved to an onboard library; in addition, it works as an image recognition system so that any unique feature can be used for alignment. Camalot’s edge detection vision alignment is the fastest and most accurate positioning method available. A one-snap operation finds all four edges of die up to 25mm square, and automatically adjusts needle path for variations in X,Y, and theta placement, die width, and edge parallelism.
Pipeline Conveyor Mode
Pipeline conveyor mode allows parallel product transfer within the machine, reducing transfer time from input buffer or preheat to dispense station in as little as 2.5 seconds, down from a standard 5 – 6 seconds. For a process that currently has a 25 second cycle time, this provides an additional 10% in UPH!
Dynamic Dual Head (DDH)
The proprietary design of Dynamic Dual Head (DDH) provides the only fast and fully accurate solution for dual head simultaneous dispensing. The DDH option uses a unique and patented mini XY drive system on a second Z-Axis to correct “real-time” and allow synchronous dispensing of both pumps regardless of part to part rotation. This technique guarantees increased productivity whilst maintaining yields through unsurpassed accuracy.
IR Temperature Sensors
Patent pending, closed-loop monitoring of the PCB/substrate temperature ensures dispenser process stability and yield improvements for underfill applications.
NanoShot is the next generation of “jetting” technology. Offering high speed – Up to 600 Hz, and ultra-fine resolution, with dot sizes < 300 microns, this patent pending pump features state-of-the-art motion control technology, simple maintenance, quick changeover, and a low cost of ownership.
A vacuum-based cleaning station ensures cleanliness of needle/nozzle. A detector is used to verify needle straightness and presence, compatible with 12–32 gauge needles.
NuJet Jetting Pump
NuJet eliminates use of a needle and incorporates a contact jetting technique to displace the dispense material. Controlling the piston with a pneumatic actuator and closed-loop software achieves a high degree of accuracy and repeatability for consistent process results.
Servo-drive Auger Screw Pumps
Camalot offer 2 types of Auger pump both controlled with a precise servo drive system. The 635SD series are typically used for finer feature dots and lines of high viscosity material. The 680SD pumps delivers high flow rates and also incorporate a patented positive shutoff that eliminates dripping of lower viscosity materials. For highly abrasive materials both pump systems offer more wear resistant carbide auger screws.
SmartStream® Pump Technology
SmartStream is a unique patented non-contact dispense method designed and manufactured by Camalot. A controlled stream of material is dispensed using positive displacement with a piston, which does not contact seat or nozzle. SmartStream dispenses a column of material with each cycle instead of a single sphere.
Dual-Mode Weight Scale
A patented closed-loop weighing process measures dispense patterns and automatically compensates for material viscosity for maximum accuracy.
