Model PF-2400 – Controlled Atmosphere Large Format Vacuum Furnace

FOR HIGH VOLUME PRODUCTION IN VACUUM AND INERT GAS ENVIRONMENTS

The PF-2400 is ideally suited for processes requiring close control of both temperature and atmosphere. Primarily intended for void-free, flux-free soldering, the PF-2400 is capable of operating at 10 millitorr vacuum levels, or at pressures as high as 50 psig using inert gasses. Temperature is controlled in increments of 1 °C from ambient up to a maximum operating temperature of 500 °C.

FEATURES AND BENEFITS:

• Windows based control system
• Infrared Sensor Package Sealing
• Void-free, flux-free soldering
• Low cost of operation



TYPICAL APPLICATIONS

Many Uses Include:

 

 Automotive diode assembly
High power eutectic die attachment
BGA and wafer solder sphere reflow
High volume component assembly



PROCESS CHAMBER

The process chamber for the PF-2400 is a stainless steel ASME certified pressure vessel. It has an inner and outer wall to accommodate water cooling. Rectangular in shape, with an automated lid sealing system and hermetically sealed feedthroughs, the chamber is capable of operating at pressures from 10 millitorr to 50 psig.

An array of upper and lower gas rakes are positioned inside the chamber to create turbulent flow directly over process boats and underneath the graphite platens. Process gas or air is selected from one of the three gas inputs, along with a programmed flow rate. This system is designed to cool the product quickly to handling temperature.

Three graphite platens arranged edge to edge constitute a single heating zone. Heating is primarily achieved via conduction from the platens into graphite fixtures holding the components. Free-floating weights may be used to apply sealing force to insure reliable solder attachment.

CONTROL SYSTEM

The PF-2400 is controlled through a distributed logic system that links intelligent temperature and pressure controller to a Windows® based central controller. All process parameters are controlled automatically with programs developed for each application.

The operator interface features a colorgraphic display with menu-driven soft keys. For process engineers and maintenance personnel a standard PC type alphanumeric keyboard may be connected for programming and maintenance functions. All operational recipes and profiles can be recorded directly on the system hard drive for future use, if desired. The system includes an RS-232/422 port for external control, host communication/Ethernet and a separate parallel port for printer output.

If Internet access is available, troubleshooting, diagnoses, maintenance and upgrades can all be performed from our manufacturing facility to anywhere in the world!

SELECTED PF-2400 OPTIONS
