PCB Layout

ELMG Digital Power design PCB for

  • Power Converters
  • Communication Links
  • Precision Analogue Systems

PCBs for power converters require microelectronic circuits and power devices on the same PCBA. The interface between the low voltage digital control and the high voltage power electronic switching devices has mains safety isolation compliance requirements such as those from IEC/EN60335 or EN50178.

ELMG use Protel and Altium PCB design tools.

PCBs are designed for test (DFT) and are designed for manufacture (DFM).

FPGA Layout

PCB layout for FPGA used to control power converters require high speed digital techniques to meet EMC and signal integrity requirements. Power supplies and PCB planes are laid out to meet the ripple and impedance requirements.
FPGA in QFP packages allow low cost and high perfomance without BGAs.

Analogue and Power Layout

ELMG precision analogue design requires sophisticated and subtle PCB layout for EMC and noise immunity.

Power switching devices like triacs and IGBTs dissipate heat when they are operating so the PCB provides heatsinking. To design these requirements for power converter and other PCBs.

Power converter isolation and safety requirements are met with PCB spacings that are often enhanced with slots.

Design for compliance in the PCB layout using slots in the PCB. This assures that the creepages and clearances meet the PCB meet the compliance standard prescribed requirements.
