T835 IRDA Welder Infrared Heating Rework Station
Features:
1. The machine selects the infrared highly effective component to give off heat which independent exploration, adopt advanced PID intelligent controlling warm heating technology, controls warm precisely.
2. Can achieve to heat PCB board and component which contains lead or not,especially suit to BGA、SMD.
3. Use infrared heat, easy to cut through, heat proportion, don’t have sirocco flow. Don’t shift the small component on the PCB board,ensure the welding quality.
4. This machine has 600W heating system, widely to 120x
5. Easily operate, can operate it through easy training. Parameter:

6. Operation method
6.1. Starting and inspections before starting:
①. Check if the cables of infra-red lamp, temperature sensor and power supply were connected well or not before starting.
②. Turn on the power supply switch. Then let the machine work till Self-checking is finished. (Temperature displayed after self-checking is your room temperature.)
③. Switches on the front panel are used to control the work process of infrared lamp. Press the front panel “▲” up button, “▼” down button to adjust the temperature of infrared lamp between 0
6.2. Sealing off/repair operation:
Will elect well the PCB board select the appropriate working position.
①.According to the chip size and the welding technological requirement, selects the suitable infrared lamp the heating temperature(0
Adopt infrared heat lamps no steps, you can adjust the size according to chip temperature freely. When the infrared heat lamps adjustment knob to adjust the largest, most powerful infrared light line, warming up faster chip, in the process of welding special attention to temperature control, to prevent displacement temperature senor chips not lead to heat a long time, heating up too high, burned chips.
②.Regulation infrared temperature senor lights, place it in the chips or aside suitable location nearby. Chip in and around the senor head painted Flux(welding or welding-oil),this would enable senor measured the temperature more accurately, while helping the solder flux role, BGA pad will be more intact, can effectively prevent the pads from the stick and tin from the hair, and other issues.
6.3. Soldering / unsoldering operation:
① Adjust infra-red lamp input temperature between 0
This machine adopts stepless methods to regulate temperature. When you regulate infra-red lamp to max power, infra-red lamp releases the strongest rays to make chip’s temperature rise fastest. In the process of welding, please pay attentions to temperature control sensor to avoid burning chips because of high temperature.
② Put the temperature sensor at the suitable place near the Chip. Spread flux on the head of sensor for accurate temperature; spread flux around the chip to guarantee better welding.
①. Fix PCB board.
②. Place the temperature sensor, spread flux, set infra red lamp work temperature, then start infra red lamp.
③. Adjust the place of infra red lamp to make the facula on the chip.
④. Adjust the height of lamp to keep the height between 20
⑤. Switch off the power after the machine completely cooled down.
General operation: First cover the PCB board that needn’t repair or that should be avoid high temperature with aluminum foil, fix PCB board well. Then set the preheat temperature between 160
For the lead-free device, the temperature can be increased 20
For two-faced board, please adopt lower preheat-temperature to preheat PCB board, supplemented by infrared heat at the top.
Welding process is nearly same as unsoldering process, but users should pay attention to clean the tin pan or pads and ball-planting, put Chip on the right place before heating.
6.4. Attentions in the process of unsoldering/welding
①. For some simply encapsulated chips, we suppose you put a small piece of aluminum foil on silicon position to prevent chips crack from overheating. The size of aluminum foil should be slightly bigger than silicon, otherwise, it will influence the welding effect.
②. In the process of unsoldering/welding, all the plastic plug-in units within the scope of infra red lamp rays should be covered with aluminum foil to prevent deforming or damaging from high temperature.
③.Clean and test the PCB board after cooled down.
④. Please don’t let infra red lamp work for long time without PCB board. To let infra red lamp irradiate the articles with strong reflection is strictly forbidden, otherwise, the service life of lamp will be shorten.
6.5. Infra-red lamp maintenance:
①. The preheating chassis and the infra-red lamp body, specially the infra-red lamp high insightful protection slide, should be regularly wiped off dust or condensate of flux by with dehydrated alcohol to keep infrared heat radiation unobstructed.
②. Put hand-help lamp back to the support after use to make infra red lamp completely cool down.
7. Attentions:
①. Don’t switch off the power after use till the fan fully cool down, which will prolong the service life of the machine.
②. Keep the intake of ventilated and lamp clean. Clean the infra-red lamp high insightful protection slide regularly with dehydrated alcohol.
③. Be careful of security under high temperature.
④. Take out the power supply plug-in if don’t use for long time.
8. Maintenance Warranty
We guarantee the machine quality for a year. The service of infrared lamp is designed for 1000 hours. We guarantee the infrared lamp is used for three months. We provide infrared lamp, but not free of charge. If you have any problems or questions about the machine, please enquiry online, we provide technical advisory.
