SCD S-Series Solar Cell with Dryer - SCD

SCD S-Series Solar Cell with Dryer – SCD

 

High Production with Fail-Safe Forming Gas Operation

Manufacturing the fastest and most efficient solar cell production IR furnaces are now available with user-selectable reducing atmosphere or standard nitrogen operation.

High production yields and throughput are achievable due to the design’s quick start-up and changeover time, offering precise and repeatable temperature profiles up to 1000 degrees C in a uniform and ultra-clean process gas atmosphere.

Computer Controlled:

The furnace is operated via ProControl software installed
on a robust managed platform RAID1 furnace computer.
The process engineer can easily vary process parameters
using the sophisticated PID and power control parameters in the software.
An almost infinite number of recipes and profiles can be labeled
and stored for ready access on the furnace computer.

The software includes 2 levels of password protected control (Engineer and Operator)
and logs each change in recipe load or furnace state
useful for troubleshooting product and process performance.

The furnace software operates on a Microsoft Windows 7 Professional computer system.
The program and all settings and recipes are stored on the RAID1 dual mirrored
redundant hard drives.

The computer is complete with 17″ LCD 1280×1024 high resolution color graphic screen,
full size keyboard/mouse interface and both Ethernet
and wireless SCD-N high-speed network connections to facilitate view
and control of the furnace by managers and process engineers from any location.

The furnace includes four (4) local USB ports,
two at entrance and two on the LCD monitor at the control panel
for connecting profilers and jump drive storage devices.

Low cost of ownership results from the furnace versatility,
high throughput, quick readiness, and low utility consumption.

Small zones and high temperature differentials enable broad profile flexibility.

Profiles with peak temperatures from 150 degrees *C*
to 1000 degrees *C* are possible.

The furnace can be turned on, turned off, or re-profiled in minutes,
saving time and money.

These are the fastest and most efficient production furnaces available
for semiconductor packaging.

High production yields and throughput are achievable
due to the design’s quick start-up and changeover time,
precise and repeatable temperature profiles up to 1000 degrees *C*.

The process gas atmosphere is uniform and ultra-clean.

All standard models (except LA-306 series and “P” models) include a RAID1 computer with LCD  screen,
full size keyboard interface and both Ethernet and wireless-N high-speed network connections
to facilitate view and control of the furnace by managers and process engineers from any location.

Four (4) local USB ports are provided,
convenient for connecting a furnace profiler and jump drive storage devices.

Our new “P” series replaces the computer control system with high quality discrete digital controllers
for cost-effective precision control on repetitive production applications.
These furnaces are a good solution in applications
where process recipes are changed infrequently and auxiliaries are at a minimum.
