Construction Techniques
□ Please take time to inventory the parts before starting. Report any shortages to QRPKITS.com (In many cases it
may be faster and cheaper to pull a replacement from your parts supply, but please let us know if we missed
something.)
□ Pre-sorting the resistors and capacitors can speed up the assembly and reduce mistakes.
□ There is no need to print out the whole assembly manual unless you want a copy. Print the Parts List and
Schematic (last two pages) then view the rest of the manual on a computer, laptop, or tablet. The Parts List
has columns for inventory and construction.
□ You can insert several parts at a time onto the board. When you insert a part bend the leads over slightly to
hold the part in place, then solder all at the same time. Clip the leads flush.
□ Most parts should be mounted as close to the board as possible. Transistors should be mounted about 1/8"
above the board. Solder one lead on ICs or IC sockets and then check to make sure the component is flush
before soldering the remaining leads.
□ Use a Temperature Controlled Soldering Station with small tip or 15-35 watt soldering iron with small tip.
Conical or very small screw driver tips are best.
□ DO NOT use a large soldering iron or soldering gun.
□ If you are a beginner, new to soldering, there are a number of resources on the web to help you get on the
right track soldering like a pro. Google Soldering Techniques.
