RAMSEY Learn-As-You-Build KIT ASSEMBLY 

 
There are numerous solder connections on the LEDS1 printed circuit board. 
Therefore, PLEASE take us seriously when we say that good soldering is 
essential to the proper operation of your kit. 
 

Use a 25-watt soldering pencil with a clean, sharp tip. 

Use only rosin-core solder intended for electronics use. 

Use bright lighting, a magnifying lamp or bench-style magnifier may 
be helpful. 

Do your work in stages, taking breaks to check your work. Carefully 
brush away wire cuttings so they don't lodge between solder 
connections. 

 
We have a two-fold "strategy" for the order of the following kit assembly 
steps. First, we install parts in physical relationship to each other, so there's 
minimal chance of inserting wires into wrong holes. Second, whenever 
possible, we install in an order that fits our "Learn-As-You Build" Kit building 
philosophy. This entails describing the circuit that you are building instead of 
just blindly installing components. We hope that this will not only make 
assembly of our kits easier, but help you to understand the circuit you’re 
constructing. 
 For each part, our word "Install" always means these steps: 
 
              1. Pick the correct part value to start with. 
 
              2. Insert it into the correct PC board location. 
 
              3. Orient it correctly, follow the PC board drawing and the written 
              directions for all parts - especially when there's a right way           
              and a wrong way to solder it in. (Diode bands, electrolytic             
              capacitor polarity, transistor shapes, dotted or notched ends        
              of IC's, and so forth.) 
 
              4. Solder all connections unless directed otherwise. Use enough 
              heat and solder flow for clean, shiny, completed connections.
