Soldering the Boards
When inserting the parts on the board, bend the leads at a 45 to 55 degree angle on the bottom side of the PCB to hold the parts on the top of the PCB.
When turning the board over for soldering, look underneath to make sure all the components are still against the board. Some may fall down and the leads need to be re-positioned to keep them against the board. Parts whose leads cannot be bent can be held in place with a short piece of masking tape.
Clip the leads after they are soldered. See Soldering Techniques for the ELR.
Build the kit with SAFETY in mind. Handle a hot soldering gun carefully and take care clipping leads.
Take your time and don't work on the kit when frustrated with life problems (though working on the kit can be relaxing therapy).
Use solder that does not leave large amounts of rosin on the board. Too much rosin will leave the board a dull color. Quality solder will produce joints with a bright silver color.
The best solder is silver solder available in a small roll (1.5 oz.) from Radio Shack, part no. 64-013 E, .022 inch diameter, 62/36/2 mix, labeled "High-Tech Rosin-Core Silver-Bearing Solder" with a red and white label. One roll will solder the receiver.
Regular lead solder that works well is 63/37 alloy sized .032 inch, 1.0mm, or 0.8mm rosin core.
Clipping Component Leads
The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator/builder that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator/builder.
Do not have the bottom of the board pointed toward your face while clipping the leads after soldering parts to the board. Some of the leads will take off like rockets and fly all over the room and maybe into your eye.
The best place to clip leads is with the board facing down into a large trash can.
Solder and Your Health
Be sure to wash your hands after every soldering session with the kit.
For the residents of California (and should be noted by everyone):
This product may contain and/or may be used with solder. Solder contains lead which is toxic. Lead is known to the State of California to cause cancer, birth defects, or other reproductive harm.
