RAMSEY Learn-As-You-Build KIT ASSEMBLY 
 
There are numerous solder connections on the MR6 printed circuit board. 
Therefore, PLEASE take us seriously when we say that good soldering is 
essential to the proper operation of your transmitter! 
 

•

Use a 25-50 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. 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 placing parts on the wrong pads. Second, whenever 
possible, we install in an order that fits our "Learn-As-You Build" Kit building 
philosophy. 
For each part, our word "Install" always means these steps: 
 
             1. Pick the correct part value to start with. 
 
             2. Place it on to 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.   
 
SURFACE MOUNT COMPONENT SOLDERING INSTRUCTIONS: 
 
You’ll notice that the circuit board contains only a few holes for component 
leads to pass through. This is because the SMT components will be affixed to 
the “solder” side of the PC board, the side that contains the PC traces. Be 
aware that the component view for assembly is looking at the solder side of 
the PC board.   
 Patience is the key when installing surface mount components. Typically, the 
first step (after identifying the component) is to “tin” one of the PC traces that 
will connect to the part. Once this is accomplished, the part can be installed 
by holding it with tweezers in contact with the “tinned” trace and re-heating
