7.Installation Tips:
1>.User needs to prepare the soldering tool at first:
1.1>.Small screwdriver
1.2>.Small wire cutters
1.3>.Fine tip soldering iron(Recommend using a fine point soldering tip)
1.4>.Good quality small gauge solder(recommend no larger than 1.0 mm)
1.5>.Magnifying glass
2>.Please be patient until the installation is complete.
3>.The soldering iron can't touch the components for a long time(1.0 second),
otherwise it will damage the components.
4>.It is recommend building the project starting with the lowest components first and
working up to the highest components. This is a common practice as it makes it easier to
hold the low components on the board while soldering
5>.Pay attention to the positive and negative of the components.
6>.Strictly prohibit short circuit.
7>.User must install the LED according to the specified rules.Otherwise some LED will
not light.
8>.Install complex components preferentially.
9>.Make sure all components are in right direction and right place.
10>.Check that all of the LED can be illuminated.
11>.Please wear anti-static gloves or anti-static wristbands when installing electronic
components.
9.Installation Steps( Please be patient ):
1>.Step 1: Install 1pcs SMD components SOP-16 RDA5807 FM Receiver at U1. Verify
and confirm the installation direction of RDA5807. The rectangular silk screen on the PCB
coincides with the crystal oscillator on the RDA5807 to locate the installation direction.
2>.Step 2: Randomly choose a pad on the PCB, and then melt the solder on this pad.
