The Dragonfly and Butterfly are designed to be mounted on a PCB, either by soldering the 
pins directly to the PCB or by using suitable socket connectors. In both cases the following 
rules apply: 

1. The 

size of the traces on the PCB (thickness and width) is determined by the current 

carrying capacity required by the application.  

 The rated continuous current limit (Ic)of the Dragonfly and Butterfly is the current 

used for sizing the motor traces  (M1, M2, M3 and PE) and power traces  (VP+, PR 

and PE). 

 For control, feedbacks and Inputs/ outputs conductors the actual current is very 

small but “generous” thickness and width of the conductors will contribute to a 

better performance and lower interferences. 

2. The 

traces should be as short as possible to minimize EMI and to minimize the heat 

generated by the conductors. 

3. The 

spacing between the high voltage conductors (VP+, PR, M1, M2, M3, VL) must be 

at least: 

 Surface layer: 

1.5 

mm 

 Internal layer: 

0.10 

mm 

Complying with the rules above will help satisfy UL safety standards, MIL-STD-275 and the 
IPC-D-275 standard for non-coated conductors, operating at voltages lower than 100VDC and 
at "unlimited altitudes" (above 10,000 meters – 30,000 feet).
