Features:

1. This machine selects the intelligent level sirocco and rapid infrared heating technology controlling, equipped with special design wind wheel, speed stability and uniform temperature, suit for uninterrupted soldering the LED and BGA components.

2. This machine is equipped with the crawler-type and five temperature area heating systems, and each temperature area uses independent PID controlling and up-down heating type, can make the inside temperature more accurate and well-proportioned, just take about 15 minutes can let it heat up to the working temperature from the room temperature.

3. Intelligent temperature wave heating type, oversized capacity wave selection, have eight temperature waves can satisfy various welding technological requirements.

4. Use programmable technology, preset the temperature wave memory storage function, can complete the whole welding process automatically according to your presetting wave.
5. Adopt the thermocouple temperature measurement and add the compensation circuit, make the temperature measurement more accurate, the wave more perfect.
6. Use PID intelligent temperature control technology; make the temperature control more accurately.Adopt the imported large current solidstate relay noncontact output can effectively avoid the IC or circuit board damage due to the rapid or uninterrupted warming up, make the whole welding process more scientific safety.

7. Transmission system adopt imported frequency conversion motor, PID closedloop speed, smooth operation, speed adjustable range 0-290mm/min.

8. Adopt independent wheel structure and special stainless steel strut, durable wearresisting runs smoothly, speed precision can reach ±10mm/min.
9. Independent cooling zone, to ensure the PCB board of low temperature when the required.
10. Friendly human-machine operation interface, perfect LCD display, no need to connect with the PC, can watch the whole repairing process very clearly.
11. Ergonomic design, practical and easily operated. Good build quality but at the same time light weight and a small footprint allows the T-960 to be easily bench positioned, transported or stored.


Foundation for wave set:

1. The reflow soldering theory and the temperature wave When the PCB board goes into heat up area (dry area), the solvent and gas in the solder paste will evaporate. At the same time, the flux can wet the pad and the component tip and foot. The solder paste melts, caves in and covers the pad, leading to the pad and component pins insulate the oxygen. PCB board goes into heat preservation area. PCB board and components get full preheating. In case of damaging the PCB and components when it goes into the welding area and the temperature heats up quickly. When PCB board goes into the welding area, the temperature heats up and the solder paste melts. When PCB board goes in to cooling area, the liquid solder paste the soldering points solidify. The reflow process is finished. The temperature is the key to welding quality. The actual and the setting temperature warming slope and the peak temperature should be accordant. Before the temperature reaches 160℃, please control the heat up speed in abou 1℃/S. If heat up too quickly, the PCB board and the components will be damaged, and the PCB board may be ou of shape. On the other side, the flux volatilizes too fast. And it is easy to make soldering tin ball. Set the peak temperature 20℃-40℃ higher than the solder paste melting point. Set the reflow time 10S~60S. If the peak temperature is low or the reflow time is short, it will affect the welding quality, and serious is causing the solder past does not melt. If the peak temperature is high or the reflow time is long, the metal power will be oxidized and affec the welding quality and seriou is causing the component and PCB board damaged.

2. The set of the temperature wave

Set the wave according to the solder paste and the above foundation. Different solder paste, choose and set different waves. In addition, the temperature wave has related to the PCB, the density and size of components. Generally lead-free welding temperature should be higher 40℃ than melting point.


Daily Maintenance:

1. Keep the electrical control cabinet clean.

2. Check the fan shaft sleeve is in good condition.

3. Check the fan and the electro-motor have abnormal sound.

4. Be sure the fan does work flexibly.
5. Check the air hole if there are abnormal materials.
6. Check the transmission net-belt is in good condition.
7. Check the electrical chest and electrical equipment have abnormal sound.
8. Check the transmission part if it is in good condition and has abnormal sound.
9. Before turn on the machine, please check the working voltage if it is in the safe voltage and if it is stable. Ensure all the parts can work safely and normally. At the same time, when turn on the machine, check the parameters are the same to the last time turn off. When turn off the machine, do not let the transmission belt in the hot area, please turn off the temperature and when cool down well and stop the transmission belt.
10. Lubricate the driving rolls. Put lubricating oil every two months.
11. The motor works in high temperature for long time, please put lubricating oil twice a week or more, ensure the motor can work normally.
12. Clean the residual goods on the fan blade and motor timely. Or the circuit ages will lead to short circuit and damage the fan.
13. Be sure the machine contacts the earth when use five-wire system.
