How to Use the Temperature Probe for Hot Air Rework System
(No. C1541)
|
The Temperature Probe for Hot Air Rework System (No. C1541) is equipped with 2 types of sensors. Before measuring temperatures as follows, connect the sensor to the thermometer ( HAKKO FG-100 or HAKKO FG-101).
|
|
|
| Sensor A: |
When measuring the temperature of hot air blown from the nozzle:
Correcting thermal control can be made by confirming the temperature of the hot air that is actually blown.
|
| Applicable products: |
SMD rework HAKKO FR-801, HAKKO FR-802, HAKKO FR-803, HAKKO 850B,
HAKKO 852, HAKKO FR-820 |
| Sensor B: |
When measuring the temperature of applicable parts (workpieces):
Rework can be performed without causing damage to the parts being reworked (QFP, etc.)
|
|
| |
|
| |
| Let’s look at how to measure the temperature using Sensor A! |
| |
First, treat the sensor A as follows:
- Bend the end as shown in the photo,
- in a contactless manner
- with a 1-2mm gap
- apply the end to the measuring point while being careful not to apply hot air to the contact section.
|
 |
Be careful that hot air is only applied to the end section. Failure to do so may not allow correct temperature to be measured. |
 |
| |
|
Next, let’s look at measurement samples using Hot Air Rework System (HAKKO FR-801, etc.) and Preheater (HAKKO FR-820).

|
|
| A) Method for measuring hot air from Hot Air Rework System |
| |
 |
Examples of use in combination with HAKKO FG-100 and HAKKO FR-803B
* It is also possible to use in combination with HAKKO FG-101.
|
 |
 |
| Remove one screw from the main body and secure probe using the screw supplied with the probe. |
Condition where the probe end is positioned in a contactless manner with a 1-2mm gap from the nozzle end. |
|
|
| |
| |
| B) Method for measuring hot air with Hot Air Rework System mounted on the rework fixture |
| |
 |
Examples of use in combination with HAKKO FG-100, rework fixture (No. C1392B) and HAKKO FR-803B
* The same method of use is employed for Hot Air Rework Systems such as HAKKO FR-801and HAKKO FR-802.
* It is also possible to use in combination with HAKKO FG-101.

 |
 |
| Loosen the fixing lever to remove the holder assembly and set collar and mount the probe on the shaft. |
Condition where the temperature probe end is positioned in a contactless manner with a 1-2mm gap from the nozzle end. |
|
| |
| |
|
| C) Method for measuring hot air from Preheater |
| |
 |
 |
| Condition where the temperature probe end is positioned in a contactless manner with a 1-2mm gap from the air outlet |
