LED SMD lamps are made of FPC circuit boards, LED lights, and high quality silicone casing. Waterproof performance, safe and convenient to use low-voltage DC power supply, various colors and bright colors; outdoor use can resist UV aging, yellowing, high temperature resistance, etc. This product is widely used in building contour lights, entertainment venues, decorative lighting, advertising decoration The field of lighting.
At present, in the LED industry, LED chip mounter is generally used to mount LED products , and the chip LED can solve the problems of brightness, viewing angle, flatness, reliability and consistency. So, what equipment do we need for LED chip processing?
The LED chip processing process can be simplified as: printing, patching, soldering, overhauling
[1] solder paste printing machine
Modern solder paste printing presses generally consist of plates, tin paste, embossing, and circuit boards. Its working principle is: firstly, the circuit board to be printed is fixed on the printing positioning table, and then the solder paste or the red glue is printed on the corresponding pad through the steel mesh by the left and right scrapers of the printing machine, and the PCB is uniformly printed. The transfer station is input to the placement machine for automatic placement.
The working procedure of the automatic solder paste printing machine:
1. Turn on the Switch, return the machine to zero, and select the program.
2. Install the support frame: adjust the track width, move the baffle cylinder, open the transport switch, place the board in the center of the track, press the button to make the board reach the specified position, and press the track clamp button.
3. Adjust the position of MARK2 to correspond with the “Ten†word of the computer section to confirm whether the production data is correct and click OK.
4. Install the steel mesh and scraper in turn: press the production setting, open the mediation window, and start production.
5. Add solder paste to the steel plate. The amount of solder paste added is higher than the blade 1/3 lower than the blade 2/3.
6, visual inspection before printing, solder paste can not be biased, even tin, less tin, cutting, uneven thickness and so on.
7. Confirm the first piece of printing by the quality personnel, and confirm the OK before normal operation.
Precautions for automatic solder paste printing machine
1. It is forbidden to operate the machine when the printing machine door is opened or fails.
2. Note that the steel mesh can not block the hole during the operation.
3, the solder paste keeps a small amount of access to the principle of multiple additions.
4. Do not print for more than one hour, please recycle the solder paste.
5. If there is a printing error in the printing, please inform the staff immediately.
