Tính năng :

Là sản phẩm công nghệ mới nhất, dùng ánh sáng hồng ngoại để gia nhiệt thay vì thổi hơi nóng theo cách truyền thống, nên đạt độ đồng đều gia nhiệt và chất lượng khò nhiệt gỡ chip rất tốt; hạn chế tối đa việc hỏng lỗi chip bởi quá nhiệt khi so sánh với khò hơi (nhiệt tác dụng ở 280 độ tương đương với 380 độ của gia nhiệt bằng khò hơi), không gây bay bắn, dịch chuyển chip do luồng hơi nhiệt như khò hơi. 

Là phương án giá rẻ nhưng rất hiệu quả, có thể dùng độc lập hoặc kết hợp với Bếp hấp hồng ngoại (T-8120) để thay thế hệ thống hàn chipset BGA nhằm hàn và tháo gỡ các chip dán SMD (gồm cả chip BGA) một cách an toàn, dễ dàng.

Dải nhiệt:

0℃-350℃

  Mô tả chi tiết :

1. Features

1. Adopt hand-held lamp structure with flexible operation and easy control. T835 is suitable for any 
points of a flat component, especially BGA, SMD components
.

2. Use infrared heat lamp. Heat is easy to pierce and distribute evenly, which overcome disadvantages 
(burn out elements) of traditional welder machines..

3. Infrared heating don't have sirocco flow. Don't impact circumjacent small elements. It is suitable 
for all of the elements. It can be used to unsolder BGA, SMD, CSP, LGA, QFP and PLCC, especially 
Micro BGA and SMD elements. T835 works together with preheating oven T-8120, which can repair 
all kinds of needle-socket (such as CPU socket and inserted row GAP).

4. Easy operation. Just need one-day training, you can operation it skillfully. Don't need any welding tools. 
This machine can solder all the flat components.
5. T-835 will satisfy soldering/unsoldering of phones, computers, notebooks, Game machines, etc.

4. Installation steps

4.1. Installation of sensor, Connection of infra-red lamp cable

Insert temperature sensor plug into corresponding socket.

. Insert Infra-red lamp cable into corresponding socket.

Rotate the screw right to fix.


4.2Install Infra-red lamp support

Use M3*8 screw to fix the infra-red lamp support to the main body as the picture shows.


5. Operation method 

5.1. Starting and inspections before starting

. Check if the cables of infra-red lamp, temperature sensor and power supply were connected well 
or not before starting.

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.)

. 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 0-350
Press the switch “ON” to let infrared lamp work; press the switch “OFF” to stop working.

5.2. Sealing off/repair operation

5.2.1 PCB board laying aside

Will elect well the PCB board select the appropriate working position.

5.2.2 Before sealing off/repair adjustment and preparatory work

.According to the chip size and the welding technological requirement, selects the suitable infrared 
lamp the heating temperature
0-350 adjustable. When the sealing off is smaller than the 15x15mm 
chip, may adjust the infra-red lamp temperature to 160-240 about; When the sealing off/repair is 
smaller than the 20x20mm chip, may adjust the infra-red lamp temperature to 220-240 about; Opens 
in a big way, when 30x30mm chip, according to the craft and the user experience, may adjust the 
infra-red lamp 240-260
 
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.

.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.

5.3. Soldering / unsoldering operation:

5.3.1. Fix the PCB board: Put the PCB board to suitable place.

5.3.2. Preparation and adjustment before soldering/unsoldering:

 Adjust infra-red lamp input temperature between 0-350 according to Chip’s size and requirements of 
welding technology. Set temperature between 160-240 to unsolder chips which size is under 15x15mm 
size; between 220-240 to unsolder chips under 20x20mm; adjust the temperature between 240-260 to unsolder chips over 30x30mm.

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.   

 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.

5.3.3 Unsoldering/ soldering process:

5.3.3.1. Unsoldering process:

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 20-30mm. When the temperature is risen to your 
preset temperature or tin pan melt, please use vacuum suction or tweezers to remove chip, then power off
the infra red lamp.

⑤. Switch off the power after the machine completely cooled down.

5.3.3.2. Unsolder all kinds of needle-socket, such as CPU, GAP, users need buy an infra preheat box.

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 160-180, put temperature sensor near the component you will unsolder or welding. Thirdly, start preheat chassis for 3-5 minutes or even longer time to make the component heated evenly. In some special conditions, please use infra red lamp 
as auxiliaries to heat quickly.
 

For the lead-free device, the temperature can be increased 20-30.

For two-faced board, please adopt lower preheat-temperature to preheat PCB board, supplemented 
by infrared heat at the top.

5.3.3.3. Welding process:

 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.

5.4. 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.
 

.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.

5.5. Infra-red lamp maintenance:

 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
.

. Put hand-help lamp back to the support after use to make infra red lamp completely cool down.

 

6. Attentions:

Don’t switch off the power after use till the fan fully cool down, which will prolong the service life 
of the machine.

. Keep the intake of ventilated and lamp clean. Clean the infra-red lamp high insightful protection 
slide regularly with dehydrated alcohol.

. Be careful of security under high temperature.

Take out the power supply plug-in if don’t use for long time.

 

7. 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.
