1206 Side Light -emitting Product Precautions for Welding Use Give You Suggestions

1206 side luminous series LED, because there is no copper foil at the bottom of the product, you need to climb the tin on the side to complete the welding. Therefore, the welding difficulty is high, and the welding process is high. If the side stickers are not posted by the side sticker, the patch is poor and high. The manufacturer recommends that you can improve the adverse rate of eating tin through the following process: 1. The size of the PCB pads must be strictly designed according to the size size. The side of the LED is different from the positive sticker. As long as the LED is biased when the tin passes the tin, it will be more and more sloppy. 2. Properly increase the amount of tinyh paste: because the side stickers are climbing tin, the tin amount must be increased, and the quality of the tin paste also requires good quality. The mesh of most market patch processing plants in the market is 0.08-0.12,1204 side posts recommended to use 0.15 mesh (this has been experimented by Foxconn production line). Add the cushion to 0.15. You can also blow the LED to the tin paste by blowing the size of the patch machine or the negative replenishment of the mouth. 3. When passing the tin, the direction of the pads should be vertical and the direction of the tin, so as to reduce the bad order caused by the order of welding. 4. Proper extension Patch time Lead -free PC: 245 degrees 58'S: Lead 230 degrees 8-10'S (not more than 10'S is suitable) For different machines of each patch factory, please check the film factory before testing. 5. If the patch manufacturer has some red glue machine machines, you can try to order red glue fixing and then patch (brushing tin-red Z rubber patch) 1206 side emitting product welding. The 1206 side glows, the front emitting LED lamp beads, the good lamp beads are in Zhuhai. Choose LED lamp bead products first to choose the right LED lamp bead manufacturer. Zhuhai manufacturers are the first choice.
