Led line lamp is made of FPC to assemble the circuit board, which is assembled with the patch led. Its advantages make the thickness of the product only the thickness of a coin, and it does not take up space.

1. Printing of solder paste. Stir the solder paste back to warm, then place a small amount on the web of the printing press. After the first trial printing, it is important to observe whether the solder paste in the position of the led solder on the FPC is full, whether there is less tin or more tin, and if there is any short circuit. This key is very critical, and the lack of security will result in poor quality.

2. Patch. Put the printed FPC on the fixture, and automatically send the board to the patch position. The sequence of the patch machine is prepared in advance. As long as there is no problem with the first plate, it will be produced in a stable way. It is important to note that the polarity of the led, the resistance of the patch resistance should not be confused, and the other thing to be noticed is that the position should not be offset.

3. Intermediate inspection. It is necessary to check the polarity of led lamp on the led lamp (whether there is any reverse), there is no deviation, no short circuit, and the resistance is correct.

4. Reflow soldering. It is important to note that the temperature of the reflux must be well controlled, and the solder paste is too low to melt. The FPC is too high for blistering. In addition, the preheating temperature should be appropriate, too low the flux of the flux is not complete, and residual after reflux will affect the appearance; Too high will cause the flux to volatilize prematurely, causing backflow, and may produce tin beads.

5. Finished product inspection. We need to check the appearance of the product, see if there are any solder, tin bead, short circuit and so on. Then the electrical inspection is conducted to test whether the electrical performance of the product is intact and the parameters are correct.

6. Packaging. This book is an electronic document material, can let you reading on any computer, easy to use, small footprint, save for a long time the packing of the general is 5 meters per roll, using anti-static moisture-proof packaging bag for packaging. In the case of packing, please attach the attachment to the attachment, so as to avoid the lack of attachment.

Led line lamp is suitable for irregular place and small space use, also because it can be arbitrary bend and winding, it is suitable for any combination of pattern in advertisement adornment.
