Wave soldering machine is the melted solder, electric pump or electromagnetic pump jet into the design requirements of the solder wave, so that the pre-loaded electronic components of the printed circuit board through the solder wave, to achieve the components of the solder end or pin and the printed circuit board pads between the mechanical and electrical connection between the soft brazing. What is the basic operation process and management of wave soldering?
I. Wave soldering machine welding preparation
1. Turn on the power, open the furnace heater.
2. Check whether the wave soldering machine time switch is normal.
3. Check whether the wave soldering machine air extraction equipment is good.
4. Check whether the furnace temperature indicator is normal.
5. Check whether the preheater is normal, set the temperature is in line with the process requirements.
6. Check the work of the foot cutting machine.
7. Check whether the flux container compressed air supply is normal.
8. Check and adjust the specific gravity of the flux is in line with requirements.
9. Solder temperature reaches the specified value, check the height of the tin surface, if less than 15mm below the furnace, you should add solder in a timely manner, add attention to the batch to join, each batch does not exceed 5kg.
10. Clear the tin surface of the tin slag, clean and add anti-oxidant.
11. Adjust the angle of the transport track: according to the width of the PCB board to be welded, adjust the track width, so that the PCB board by the clamping force is moderate.
II. The wave soldering on the production operation process
1. Turn on the flux switch, foam when the foam adjustment board thickness of l / 2 place; spray requirements board surface uniformity, spray amount appropriate, generally to not spray component surface is appropriate.
2. Adjust the wind knife air volume, so that the excess flux on the board drops back to the foam tank, to avoid dripping to the preheater, causing a fire.
3. Turn on the transportation switch, adjust the transportation speed to the desired value.
4. Turn on the cooling fan.
III. The wave soldering machine welding after the operation process
1. Turn off the preheater, tin furnace wave, flux, transportation, cooling fan, foot cutter and other switches.
2. The flux in the foaming tank about two weeks of use needs to be replaced, and in the process of regular measurement.
3. After shutting down the machine need to wave machine, chain claw clean, spray nozzle with dilute flip soak and clean.
Features of NeoDen Wave Soldering Machine
1. The layout of the overall mechanism is reasonably designed, simple to operate and easy to maintain.
2. The first wave and the second wave both adopt stepless electronic frequency conversion technology, independent control, suitable for various types of PCB board welding.
3. The preheating system and welding system both adopt PID control mode, with high precision of temperature control.
4. The area of flux spraying is automatically controlled by the size of PCB without manual adjustment of sensor position.
5. Transportation system adopts stepless electronic speed control system with closed-loop control and stable speed.
6. Wave soldering oven has over-temperature sound light alarm, emergency braking system, all motors have overload protection system.
7. It can be turned on fully automatically according to the date and time set by the user.
