The Electronic Solder DIY Kits are used to installed to a FM Digital Radio (87-108MHz).

This soldering DIY kit help you to learn basic electronic knowledge and circuit principles, and practice soldering skills enjoyably for you, or students, or DIYers. At the same time, you will own a FM Stereo which has excellent sound quality, stable performance and cool appearance when you finish the project.

Supplies

Getting started with basic electronics is easier than you might think. This Instructable will hopefully demystify the basics of electronics so that anyone with an interest in building circuits can hit the ground running.

Step 1: Install 4.7ohm Metal Film Resistor & Install 220Kohm Metal Film Resistor

Installation Tips:

 1>.User needs to prepare the welding tool at first.

2>.Please be patient until the installation is complete.

3>.The package is DIY kit.It need finish install by user.

4>.The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components.

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>.It is strongly recommended to read the installation manual before starting installation!!!

11>.Please wear anti-static gloves or anti-static wristbands when installing electronic components.
