PROCESS DEVELOPMENT

INTRODUCTION

The ThermoFlo Unit provides the user with the ability to perform non-destructive, repeatable, high quality,
component installation or removal operations. The operator can adjust the parameters of air temperature, air flow
rate (blower speed), cycle time, nozzle configuration and pre/auxiliary heating to suit the heating characteristics
of the particular component and substrate. Once you have established the desired profile, the process parameter
details can then be entered on the Profile Control Chart for future reference and programmed into the ThermoFlo
Unit memory. The Profile Log can be used for summarizing required parameters for profiles in Manual, Timed or
Program Modes. Once the Profile is entered into memory, the program can be quickly initiated (in Program
Mode). Up to 80 user-defined profiles may be stored in microprocessor memory.
When developing Profiles, PACE recommends the use of embedded
thermocouples on a test board to ensure optimum process results.

PROFILE DEVELOPMENT

1. The Profile Control Chart details the complete parameters for a developed profile. The Profile Log is
a quick reference log sheet detailing basic profile information (including stored profile number) on a
number of Profiles.
2. Develop the rework profile which adheres to your company guidelines and provides optimum results.
3. Enter the established Profile parameters on the Profile Control Chart.
4. Enter the Profile in system memory (see "Program Mode" in the Operation section of this manual for
details).
5. Enter the Profile information on the Profile Log..
