It needs to adjust the basic setting of reflow soldering before circuit board soldering enter into reflow soldering.
(1) Over-reflow soldering requires adjustment of the appropriate furnace temperature and card board size for different pcba boards.
(2) The new PCBA product needs to be confirmed by the engineer before pass the furnace.
(3)The furnace operation can be carried out after temperature is constant, , and the indicator light is green to indicate that the temperature is constant.
(4) The PCBA spacing of the furnace should be kept above 30cm, and it should not be too dense.
Start-up procedure for reflow oven
(1) Turn on the main power switch and turn on the reflow oven power switch.
(2) Turn on the PC computer power.
(3) After startup, open the application program.
(4) Select suitable furnace temperature.
(5) Adjust the width of the board track.
After confirming that the indexes are normal and the temperature meets the requirements, the pcb board is placed flatly on the chain or chain belt.
Shutdown steps for reflow soldering:
(1) Wait for the furnace temperature to drop below 200
(2) Close the WINDOWS interface until the computer to shut down
(3) Turn off the power of the reflow furnace
(4) Turn off the power supply main gate
The following precautions should be taken when applying reflow soldering equipment:
1.Wearing anti-electric gloves or anti-static bracelets when touching PCB and temperature and humidity sensitive components.
2.The furnace temperature setting should refer to the “Reflow Furnace Temperature Management Specification” to adjust the appropriate furnace temperature curve.
3.The distance between the pcb boards should be kept above 30CM.4.When placing the circuit board, it should be automatically fed with the chain. Do not push or pull the circuit board .
4.When resetting the temperature, it must be confirmed that there is no board in the furnace.5.Non-engineers or designated users are not allowed to use the equipment privately.
5.If the chain does not rotate during the operation of the machine,you should immediately press the emergency button next to it and notify the engineering personnel.
During the manufacturing process of the circuit board, the temperature setting of the reflow oven determines the temperature resistance and soldering effect of the components. Sometimes it is not possible to debug as request when debugging the temperature curve. This is because for a specific pac...
The choice of wave soldering machine should be based on process requirements and process characteristics of PCB manufacturing. For example, if the the product output is large, it is necessary to consider the use of a long preheating zone; if the surface treatment of the PCB is OSP, a wave solderi...
The tea conversation,literal meaning is to chat experience and opinions while drinking tea. Basically, in my cognition, this kind of tea party usually appears in the occasion where the leader cadres ask for opinions and suggestions on some issues. On Saturday afternoon, we suddenly received a not...
