Section 1207 Japanese uniq foods goods

Product Features: self-developed infrared desoldering techniques. Use infrared heat, penetrating power, the device is heated evenly, breaking the traditional demolition uniq foods hot air welder covering heating elements, thermal shock greater disadvantages. Easy to operate, after a day of training can fully operate the machine. No desoldering fixture, welding machine 15x15-25x25mm all removable components. The machine is equipped uniq foods with 650W Preheat Sol system, preheat the scope of 120x80mm. Infrared heating without hot air flow will not affect the surrounding small components, applicable to all the elements, uniq foods especially Micro BGA component. Features: T-862 T-860 is an upgrade, with a more sophisticated temperature control technology, increasing uniq foods the precision temperature lead-free soldering iron to make the operation more concise uniq foods and accurate. Product Specifications: Power supply uniq foods voltage: AC220V 50Hz; (AC110V 60Hz customized sold separately); Rated power: 600w; preset temperature: 100 -350 ; Weight:. 10KG heating elements: an infrared light source installed steps: 1. Load guide column. uniq foods First loosen the fastening nut focusing frame, press the arrow indicates the direction of insertion guide posts. 2. Replace the retaining ring. Relax positioning ring fastening nut, press the arrow indicates the direction of load positioning ring, after loading the rotational positioning ring fastening nut to secure it at the appropriate height. 3. The overall assembly. Focus frame fastening nut relax. pick up the focusing frame, so that the corresponding column-aligned chassis nut, rotating guide posts. Rotate the focus frame fastening nut so that the focusing frame fixed. 4. Connect the infrared lamp body cable. alignment insert the cable plug infrared light cable outlet. Rotate screws. How to use: 1, start: , check the lamp body and the power cord is connected. , turn on the power switch. And other self-test uniq foods before use by (displayed when you last used to set values on the panel display). , three front panel switches control the pre-hot uniq foods melt adhesive disc, light body 936 and lead-free soldering iron work. , press the temperature adjustment button, you can adjust the setting of each window, increase, decrease the value, press automatically uniq foods stored in the machine. Displays the current value of the next boot. 2, desoldering: , board placement and light body height adjustment: the circuit board mounted on the circuit board bracket, adjust the positioning ring and focusing frame knob, vertical alignment chip focal spot lamp body; adjust lights height, keep the cap and desoldering object uniq foods height of 20-30mm is appropriate. Temperature , preheat coil settings: general lead-free uniq foods soldering desoldering chips, more than 30x30mm and coated with a waterproof sealant solid chip, be sure to pre-board hot melt adhesives. General preheating temperature setting: leaded solder board, set preheat temperature 120-140 degrees; lead-free circuit board set preheat temperature 160-200 degrees (which is the temperature of preheated uniq foods pan). Open the preheating chassis, the display setpoint temperature stabilized at about 3-5 minutes, then turn the infrared lamp heating chip, in order to ensure uniq foods the glue and preheat requirements, except desoldering succeed. , adjust the lamp body temperature peaks: According desoldering the chip size, the appropriate body to adjust light output temperature peak, the peak temperature is adjustable uniq foods from 100-350 ; when folded less than 15x15mm chip, can be adjusted to about 160-240 , demolition 15x15mm- When 30x30mm, peak temperature can be adjusted to 240-320 , demolition larger than 30x30mm chip transferred uniq foods 350 , this time to keep the lamp body direct, this time the strongest infrared light (please note the time of self-control to prevent overheating chip burn). Note: The peak temperature is below 248 , the light will shine intermittent, intermittent heating. , according to the chip size, adjust the focus knob. Spot to cover the whole chip is appropriate. Before , desoldering uniq foods the chip, the first in the bottom or side of the chip inject a small amount of flux, solder balls can be intact, while protecting the land, so desoldering process more smoothly. uniq foods , after over a suitable time, the melting point of tin, remove the chip. Generally following the demolition of less than 15x15mm, around 20-40s; demolition 15x15mm-30x30mm, around 30-60s; greater than 30x30mm uniq foods chip, about 60-90s; 3, reflow: , cleaning pads: 936 machine comes with a quick iron with suction-line, flux, cleared land. Painted a little liquid flux spare. , first planted the ball good or scraping tin tin pulp good BGA chip, according to the registration requirements of the cleaned gently on the good pad. Then the circuit board mounted on the circuit board bracket, adjustable stand, vertical alignment chip focal spot lamp body; then adjust the height of the lamp, keep the cap and desoldering object height 20-30mm appropriate. , open preheat coil switch, preheating, wait until after reaching the preheat temperature (flux at this time has begun to restore infiltration pad pad oxide), quickly open the top of the heating lamps, and other volatile flux after the collapse chip 10 within seconds after turning off the top and preheat coil, and so the board is cooled to below 100 degrees, the board removed, put aside to cool. , the weld has cooled board, washer fluid and dried after cleaning, you can power test. If the test pass, first find the cause, and then engage in a clear reason to prevent damage to the board repeatedly welding. , 936 fast unleaded iron Use: Turn the power switch, set the desired temperature, turn the control switch. ***, General uniq foods power test, but the reasons are the following, for reference: 1, pad clean up bad, Weld; 2, solder paste reflow temperature less than, Weld; 3, heating fast flux volatiles too fast, resulting in gas explosion, causing chip shift, tin tin beads bead connection shorted or absence of Weld. 4, the board must first finish welding and other cool before cleaning, no washing or cleaning is not dry, the power will burn the board. Note 1, after the work is completed, uniq foods do not immediately turn off the power, the fan cooling the lamp body. 2, to maintain unimpeded ventilation vents, light body and clean. uniq foods 3, guide posts, the focus bracket timely wipe grease. 4, for a long time do not use, you should unplug the power cord. 5, careful, high-temperature operation, pay attention to safety.
