What's wrong with the KIC furnace temperature tester's inability to display the tin furnace temperature during peak soldering?

A furnace temperature tester is an instrument used to measure the temperature distribution of products during various hot working processes. The instrument itself can work at high temperatures, and the instrument and workpiece enter the furnace together to obtain the actual temperature curve of the surface and center of the entire process product, as well as the distribution of oven temperature. This is a powerful helper for quickly and timely solving problems in the baking process, improving production capacity, product quality, reducing production costs, and product scrap.

From a professional technical perspective, the KIC furnace temperature tester can measure temperature, indicating that there is no problem with the KIC furnace temperature tester. Where exactly is the problem?

1: Those who have used the KIC furnace temperature tester understand that there are three settings: trigger temperature, intermediate start temperature, and stop temperature. These three settings are generally located in the LOG folder of the installation file. Notepad can be used to open corrections. Usually, the KIC furnace temperature tester measures peak welding, with a system default value of 5 sampling frequency, a starting temperature of 110 degrees Celsius in the middle, and a stopping temperature of 90 degrees Celsius. The following are the settings parameters for wave soldering in the LOG folder of the KIC installation file: It is generally not recommended to modify them!

WAVESECTION=

SampleRatePerSecondForWAVE=5.000000

WaveMidpointTriggerTemperature=11000000

WaveStopTriggerTemperature=90.00000

TEMPVsTIME_Section=

SampleRatePerSecondForTempVsTime=5.000000

WAVE-PROFILE-Section=

SampleRatePerSecondForWaveProfile=5.000000

WaveProfileMidpointTriggerTemperature=11000000

WaveProfileStopTriggerTemperature=90.00000

2: The problem lies in the stopping temperature and sampling frequency. Usually, the insulation effect of the wave peak preheating zone is poor, and many wave soldering processes do not have IR zone thermal compensation installed. The temperature in the blank area between the preheating and the tin furnace dropped sharply below 90 degrees, so the KIC furnace temperature tester stopped recording, resulting in what the landlord said happened. So it's not the problem with the KIC furnace temperature gauge itself, the problem still lies in setting the parameters.

3: There are two solutions:

3.1 Increase the temperature of the preheating zone further; Keep the temperature of the circuit board surface above 90 degrees and enter the tin furnace area;

3.2 Modify the sampling frequency to 10, modify the intermediate starting temperature (85-100) and stopping temperature (65-80);

3.3 Download the brand new software again (2010 version software, can be modified directly on the operating interface)
