Vacuum anaerobic oven

Lead frames are used in semiconductor packaging processes. As carriers of semiconductor chips, lead frames are mainly made of oxidizable elements such as copper, which is easily generated in high-temperature environmentsCuO.During the reflow soldering process in the later stage, faults and fractures may occur.

So the lead frame packaging needs to be baked and cured in an anaerobic environment.

Due to some special occasions that require a vacuum environment, our company has launched a product that operates in a vacuum environmentVacuum anaerobic oven.

Anaerobic ovenHeating and warming are required in a nitrogen filled environment, hence it is also known as:Anaerobic nitrogen filling oven

1、 Basic functions of vacuum anaerobic oven

feeding→evacuate→Warm up at room temperature→Reaching the set temperature (an alarm will be triggered if the temperature exceeds the limit)→Maintain a constant temperature and start timing→Stop heating and sound an alarm when the time is up→Automatic cooling→Cutting materials.

2、 Main technical parameters of vacuum anaerobic oven

IIISemiconductor ovenBasic requirements

1Power supply:380V/220V，50Hz~60HzEquipped with phase sequence protectors and structural grounding protection.

2Nitrogen requirements:0.4-0.6MPaComes with a built-in grading filter.

4、 Equipment control system

1AdoptingPIDAutomatically calculate the magnitude of output power; As the temperature approaches the set value, the output power decreases to achieve constant temperature control and save energy.

2When the actual detected temperature exceeds the set value of the over temperature protection thermostat, the heating power supply will be automatically cut off, providing dual protection function.

3Timing is divided into 2 Gear (manual)/Automatic: When manual is selected, the timer starts immediately; When selecting automatic, the temperature must reach. The timer only starts when the set temperature value is reached, and when the time is reached, there will be an audible and visual alarm and automatic shutdown.

4Heating and cooling: instrument program editing control, temperature range can be set, cooling, heating, constant, time.

5Internal oven: The surface should be smooth and there should be no air leakage.

6Shell temperature: room temperature150Within ℃, the shell temperature should not exceed room temperature+20℃, except for joints.

7External materials: using cold-rolled steel plate surface electrostatic spraying treatment, with a plate thickness of1.2mm;

8Thermal insulation materials:It is non combustible and has strong insulation properties, using fiberglass insulation cotton and six sided insulation.

9The sealing strip is made of silicone rubber strip, which can withstand temperature without deformation.

10Inner liner material:304Stainless steel plate, with a thickness of5mmGallbladder cleaning, rust prevention, and corrosion resistance.

11Each box is equipped with3A fence style shelf.

12The door and inner container adopt a double-layer sealing form to enhance the sealing effect.

13The temperature controller adoptsPVandSVDisplay function, built-inPIDAutomatic tuning calculation output, precise control.

14Time control is adoptedLEDDigital display time controller, can set the maximum time to 99 Small, the unit can be freely switched to hours, minutes, and seconds.

15The over temperature protection thermostat adopts the Yudian energy type thermostat,PVandSVdoubleLEDDisplay function: When the temperature exceeds the set value of the over temperature protection thermostat, the heating power supply will be automatically cut off.

16The side of the box is equipped with exhaust.

17Structural component safety grounding protection.

18Equipped with an alarm light with a buzzer.

19The heating tube control adopts YangmingSSRSolid state relay controls each group of heating tubes.

20Adjustable gas flow rate to make the temperature inside the furnace more uniform.

21The control program is easy to create.

22It is equipped with a nitrogen inlet and controlled by a power distribution magnetic valve. Each set of flow meters can manually adjust the inflation flow rate and automatically control the number of flow meters opened.

23After turning on the power switch, the machine performs a self-test. If it is normal, the indicator light will display a green light. If there is an abnormality, the indicator light will display a red light.

24Equipped withUSBInterface with data export function and temperature control curve monitoring.

25The fault diagnosis is simple.

5、 Equipment working environment

1Environmental temperature:10~40℃；

2Environmental humidity:10%~85%RH.

6、 Assembly requirements for anaerobic oven

1The wiring should be neat, convenient, and aesthetically pleasing. The shorter the connection with the equipment, the better. The intermediate joints should be firmly connected and not hinder future maintenance work.

2Reserve grounding positions for all devices.
