General Information

Introduction

Thank you for purchasing the PACE HS 200 Heat Wave system. This manual will
provide you with the information necessary to properly set up, operate and maintain
the HS 200 Heat Wave system.

The HS 200 is a fully integrated system which provides temperature controlled
bottom preheating of high mass electronic assemblies and components. Users can
select forced convective (forced air) or conductive (direct hot plate contact)
preheating.

The system utilizes the PPS 28 Heat Wave power source which incorporates
microprocessor control of system features as defined by the user (e.g., temperature
limits, password lock and scheduled operations). An integral motor pump supplies
forced air (air pressure) for convective applications and vacuum for component
handling operations using the PACE Pik-Vac handpiece.

NOTE

The PPS 28 Heat Wave power source is designed specifically for use with
the HS 200 Heat Wave system only. DO NOT use with any PACE
accessories other than the Heat Wave Heater Unit.

Preheat Guidelines

Introduction

The Heat Wave system provides process control to meet your specific requirements.
Follow these steps and use the following tables as a guideline to set the process
parameters for your particular applications:

1. Determine your basic board type:
a. Simple, Double Sided Board

b. SMT/Thru-Hole Board with approximately 6 or fewer internal layers

c. High Mass Board with approximately 7 or more internal layers

2. Determine your desired preheat temperature. The tables provide data for

commonly used preheat temperatures of 80 °C (176 °F), 100 °C (212 °F)
and 120 °C (248 °F).

3. To preheat quickly (yet always slower than 3 °C per second), see Table 1.

4. To preheat (always slower than 3 °C per second) and soak the board area

prior to reflow, see Table 2. Using this method:

a) the internal pump delivers hot air for quick ramp preheating.

b) when the pump stops, the radiant convection of the hot plate provides

a controlled soak at the desired preheat temperature.

NOTE

Thermal characteristics of every board assembly will be different. The
following tables provide a base starting point for the development of the
exact preheating parameters for your rework process.

When developing processes for removal/replacement of components, PACE
recommends the use of embedded thermocouples on the test board to
ensure optimum results.

14

Preheat Guidelines

The following graph depicts a typical preheat and soak profile for a circuit board.

Setting the parameters in Table 1 will maximize the temperature ramp rate (3°C per
second or slower). Rework can then be performed immediately when the pump
turns off. The radiant heat from the hot plate will continue to slowly increase the
temperature of the workpiece.

Use the parameters in Table 2 to achieve a true ramp and soak temperature profile as
shown below. In this case, the radiant heat stabilizes the workpiece at the desired
preheat temperature.

15

Preheat Guidelines

Safe, Rapid Preheating

To preheat quickly at safe ramp rates, set the following temperature and pump run­time parameters for the appropriate board type. These settings will quickly preheat
the repair area over the center of the Heat Wave plate to the desired temperature (yet
always slower than 3 °C per second). The entire board area over the Heat Wave plate
will also be preheated, but at a slightly slower rate.

This method allows the operator to quickly perform any necessary rework tasks. The
temperature on the board may continue to rise (at a slower rate) even after the pump
turns off.

Preheat & Soak

The Heat Wave can be used to preheat and soak a circuit board before reflow takes
place. This helps to bake out the laminate and to equalize temperatures across the
repair area.

To preheat at a safe ramp rate, followed by a soak time (repair area of board
remaining within ±10 °C of desired preheat temperature), set the following
temperature and pump run-time parameters for the appropriate board type.

This method provides quick ramp preheating. When the pump stops, the radiant
convection of the hot plate provides a controlled soak at the desired preheat
temperature. This prevents the board from heating more than 10°C over the desired
temperature.
