Advantages of Sixteen Zone SMT Reflow Oven
Advanced Soldering Technology:
Sixteen zone SMT reflow ovens stand as beacons of advanced soldering technology, redefining the assembly process. These machines ensure precise reflow soldering of surface mount electronic components to PCBs, guaranteeing impeccable connections and elevated reliability in electronic assemblies.
Diverse Range of Applications:
Whether it's a specialized PCB reflow process or the demand for a controlled atmosphere, sixteen zone SMT reflow ovens offer a versatile solution, adapting to various applications in the dynamic field of SMT.
Tailored Temperature Profiles:
Control over temperature profiles is paramount in PCB assembly. sixteen zone SMT reflow ovens provide a sophisticated solution by offering precise temperature control during the soldering process.
Smart Controls for Efficiency:
Equipped with advanced controllers, sixteen zone SMT reflow ovens contribute to the efficiency of the assembly process. These smart features automate and streamline the reflow soldering process, reducing human error and ensuring consistent, high-quality solder joints.
Cost-Effective and Reliable:
Sixteen zone SMT reflow ovens not only excel in technology but also present cost-effective soldering solutions. Their efficiency in energy consumption, coupled with reduced rework and defects, makes them a cost-efficient investment for manufacturers seeking both precision and financial prudence in PCB assembly.
Heating Zone Of Sixteen Zone SMT Reflow Oven
Heating Zones:
These zones gradually heat the board to the appropriate temperature for solder melting. They ensure uniform heating across the PCB.
Peak Zone:
This is where the temperature reaches the highest point, usually around 230-250°C (446-482°F), allowing the solder paste to fully melt.
Cooling Zones:
After the peak zone, the board enters the cooling zones, where the temperature is gradually lowered to solidify the solder joints and prevent thermal shock.
The more zones a reflow oven has, the more control you have over the heating and cooling process, which leads to higher-quality solder joints and better overall results.
Basic Principles of Sixteen Zone SMT Reflow Oven
Preheat Phase:
This stage gently heats the assembly to avoid thermal shock to the components. The temperature gradually increases to around 150°C to 200°C. This helps activate the flux in the solder paste.
Soak Phase:
The purpose of this phase is to equalize the temperature across the PCB and activate the flux to clean the metal surfaces. It usually happens between 150°C and 250°C (302°F and 482°F), lasting for about 60-120 seconds.
Reflow Phase:
This is when the temperature rises to the point where the solder paste melts, typically reaching a peak between 217°C and 250°C (423°F to 482°F) for lead-free solder. The exact peak temperature depends on the solder paste formulation. This phase ensures the solder melts and flows to form solid joints.
Cooling Phase:
After reflow, the assembly is cooled down in a controlled manner to solidify the solder, forming strong electrical and mechanical connections. Cooling should be done at a rate that prevents the formation of undesirable microstructures in the solder, which can affect the joint's reliability.
Sixteen Zone SMT Reflow Oven Operation Steps
Check that there is debris inside the equipment, do a good job of cleaning, to ensure safety, turn on the machine, select the production program to open the temperature settings.
Reflow oven guide width to be adjusted according to the width of the PCB, open the transport wind, mesh belt transport, cooling fan.
Sixteen zone SMT reflow oven temperature control has lead high (245 ± 5) ℃, lead products tin furnace temperature control at (255 ± 5) ℃, preheating temperature: 80 ℃ ~ 110 ℃. According to the parameters given by the welding production process strictly and rigorously control the reflow machine computer parameters setting, record the reflow machine parameters on time every day.
In order to successively turn on the temperature switch, to be temperature to the set temperature when you can start over, PCB, board, over the board pay attention to the direction. Ensure that the distance between 2 consecutive boards of the conveyor belt is not less than 10mm.
The reflow soldering conveyor belt width adjustment to the appropriate position, the width of the conveyor belt and flatness and line board, check the material to be processed batch number and related technical requirements.
Solder joints must be smooth and bright, the circuit board must be all pads on the tin; poorly soldered lines must be re-over, the second re-over shall be carried out after cooling.
To wear gloves to pick up the solder PCB, only touch the edge of the PCB, sampling 10 samples per hour, check the bad condition, and record data. During the production process, if you find that the parameters cannot meet the requirements of production, you cannot adjust the parameters yourself, you must immediately notify the technician to deal with.
Measure the temperature: plug the sensor in turn into the tester's receiving socket, turn on the tester power switch, place the tester inside the reflow solder with the old PCB board up over the reflow solder, remove the tester with a computer to read the temperature data recorded during the reflow soldering process, that is, the original data for the sixteen zone SMT reflow oven's temperature curve.
Will have soldered the board according to the single number, name, etc. classified put. In order to prevent mixing materials to produce bad.
