How to Check the 8 zone reflow oven curve


 

Temperature and time of eight temperature zones:

 

Temperature zone 1: 148 degrees;

Temperature zone 2: 180 degrees;

Temperature zone 3: 183 degrees;

Temperature zone 4: 168 degrees;

Temperature zone 5: 174 degrees;

Temperature zone 6: 198 degrees;

Temperature Zone seven: 240 degrees;

temperature zone eight: 252 degrees;

 

transportation speed: 0.6m/min; over-temperature alarm is set at 10 degrees.

 

Generally speaking, reflow soldering has only four temperature zones: preheating zone, constant temperature zone, reflow soldering zone, and cooling zone.

 

Regardless of how many temperature zones are used for reflow soldering, their temperature settings are set according to the principle of action of these four temperature zones. Generally, there are more eight-temperature zone reflow soldering on the market.

 

There is a certain temperature difference between the actual measurement temperature of reflow soldering and the set temperature of reflow soldering.

 

In fact, the high soldering temperature of lead-free reflow soldering is 245 degrees. The temperature of reflow soldering is set according to the temperature curve provided by the solder paste factory and the actual soldering product

 

 

Lead-free process: preheating zone: heating rate is 1.0~3.0℃/sec; immersion zone: heating rate is less than 2℃/sec, time 70~130℃/sec, temperature: 160~200℃; reflow zone: highest The temperature is 220~250℃, and the time above 220℃ is 30~90 seconds; cooling zone: the cooling rate is less than 4℃/s, the cooling termination temperature is preferably not higher than 75℃

CNSMT8 temperature zone reflow soldering temperature zone is mainly divided into four temperature zones: preheating zone, constant temperature zone, welding zone, and cooling zone.


Preheating zone


Preheating is the first stage of the reflow process. During this reflow phase, the entire circuit board assembly is continuously heated towards the target temperature.

 

The main purpose of the preheating stage is to make the entire circuit board assembly safely reach the pre-reflow temperature. Preheating is also an opportunity for degassing of volatile solvents in the solder paste. In order for the paste-like solvent to be properly discharged and the components to safely reach the pre-reflow temperature, the PCB must be heated in a consistent linear manner.

 

An important indicator of the first stage of the reflow process is the temperature slope or temperature rise time. This is usually measured in degrees Celsius, C/s per second.

 

Many variables can affect this data, including: target processing time, solder paste volatility, and component considerations. It is important to consider all these process variables, but in most cases, consideration of sensitive components is crucial. "If the temperature changes too quickly, many components will break.

 

The maximum thermal change rate that the most sensitive component can withstand becomes the maximum allowable slope." However, if thermal elements are not used and yield is maximized, the slope can be adjusted to improve processing time.

 

Therefore, many manufacturers increase these slopes to the maximum universal allowable rate of 3.0°C/sec. On the contrary, if a solder paste containing a particularly strong solvent is used, heating the component too fast will easily cause an out of control process. Due to the degassing of volatile solvents, they may spill solder from the pads and solder plates.

 

Solder balls are the main problem of violent outgassing during the preheating phase. Once the circuit board heats up to temperature during the preheating phase, it should enter the constant temperature phase or the pre-reflow phase.

Constant temperature zone

 

Reflow soldering constant temperature zone is usually 60 to 120 seconds of exposure, used to remove solder paste volatiles and flux activation, where the flux group begins to oxidize and reduce on component leads and pads.

 

Excessive temperatures can cause solder splashing or balling, as well as oxidation of solder paste attachment pads and component terminals. Similarly, if the temperature is too low, the flux may not be fully activated.


Welding zone


The common peak temperature is 20-40°C higher than the liquidus. [1] The limit is determined by the component with the lowest high temperature resistance (the component most susceptible to heat damage) on the assembly.

 

The standard guideline is to subtract 5°C from the maximum temperature that the most vulnerable component can withstand to reach the maximum process temperature. It is important to monitor the process temperature to prevent exceeding this limit.

 

In addition, high temperatures (over 260°C) may damage the internal chips of SMT components and promote the growth of intermetallic compounds. Conversely, a temperature that is not hot enough may prevent the slurry from fully reflowing.

 

Cooling zone


The last area is a cooling area, which is used to gradually cool the processed board and solidify the solder joints. Proper cooling can inhibit the formation of excess intermetallic compounds or thermal shock to the components.

 

The typical temperature range of the cooling zone is 30-100°C. It is generally recommended that the cooling rate be 4°C/s. This is the parameter to be considered when analyzing the results of the process
