no reflow, to operate as step 4. If the reflow is too fast, please keep correct p
roportion to increase or reduce the temperature. And let the PCB pass the syst
em again until reach the reflow critical point. Then turn to step 4, only when
there is reflow that is good.
4. If there is no reflow, please reduce the belt speed. For example, now the belt speed
is 500mm/min, please adjust it to about 460mm/min. Usually, reduce the speed 10%
can increase the reflow temperature about 16
℃
. Another way is that, do not adjust the
speed, and increase the temperature properly. The increase range based on the
standard temperature wave. Adjust the temperature on the basis difference between
PCB actual and standard curve temperature. The adjust range is about 5
℃
.When
adjust the temperature, it can not exceed the PCB and component bearing capacity.
5. Let the PCB board pass the reflow system in the new speed or new set temperature.
If there is no reflow, back to step 4 to adjust again. Or carry out the step 6 for
temperature fine-turning.
6. The heat temperature wave is adjustable according to the PCB board. You can
adjust the transmission belt speed to adjust the temperature. Reduce the belt speed can
increase the product heat temperature. On the contrary, you can reduce the product
heat temperature.
7. Attention:the PCB passes the reflow and it reflow not very completely, suggest you
adjust then reflow again. Usually this cannot damage the components.
8. From low to high when set temperature. If the heat range is over the reflow
temperature too high, should increase the transmission speed or reduce the set
temperature. The detailed operation is opposite to step 4.
Equipment Installation
1. Set up field.
1.1. Please do the work in the clean environment condition.
1.2. Do not put the machine near the electromagnetism interfering resource.
1.3. Do not put the oven exits and entrances face towards to the fan and the window.
2. Power supply
Please use five-wire system 380V. Ensure the machine contacts the earth well and
request a professional electrician operation.
3. Adjust the reflow oven height.
By adjust the machine leg to adjust the height. The way is follow: use industrial or
alcohol level to measure. Then adjust the machine leg to adjust the machine on all
sides till it is completely horizontal.
4. Caution:
4.1. The working environment should be clean. So the welder quality is good.
4.2. Do not use and store the machine out of door, high temperature and humid
condition.
4.3. During operation take care of the high temperature, avoid scald.
4.4. When overhaul the machine, please cut off the power supply to avoid electric
shock or cause short circuit. And turn on the machine at room temp as far as possible.
4.5. If move the machine after overhaul, must check all the parts, especially the
