11.SMD IC Installation Method:
1>.Step 1: Melt a small amount of solder on the pad which IC can placed(It is used for
positioning the chip in the next step).
2>.Step 2: Hold the chip with tweezers and adjust the position so that the pins of the
chip coincide with all the pads and are close to the pads.Pay attention to the mounting
direction of the chip.
3>.Step 3: Use a soldering iron to melt the solder just now so that the chip can be
fixed.At this time, the tweezers are still holding the chip and keep calibrating the position.
4>.Step 4: Melt a lot of solder on top of another row of chip pins.Make sure there is
enough solder between each pin and the pad.
5>.Step 5: Using a solder sucker to suck out excess solder. While heating with a
soldering iron, suck out excess solder. Tips: First find a suitable place to place the tin
remover, and then use a soldering iron to melt the solder.
6>.Step 6: Check whether enough pads are filled between each pin and pad.
Otherwise, you need to add more solder.
7>.Step 7: In the same way, install another row of pins.
8>.Note:This is an installation method of the SMD chip, and user can also use other
installation methods.
