Printed circuit design is an essential activity for virtually all electronic based products. The designer must take into account technical, regulatory and commercial factors during design implementation.
Who can benefit?
Electronic circuit and system designers, PCB designers and mechanical design engineers operating in an electronic product development environment.
To develop competencies in advanced PCB design techniques
The module uses guided design exercises of typical circuit building blocks to develop competencies. For each exercise the student will be provided with circuit diagrams, requirements and appropriate constraints which will closely emulate a typical PCB design environment.
The student will carry out full designs, from schematic capture, component layout, routing, and the generation of manufacturing information.
Exercises will, where possible, be supported by detailed solutions that demonstrate good PCB design practice for LVD, EMC and signal integrity.
Typical circuit building blocks are listed below:-
Regulated Power Supply - PCB mounted mains transformer and rectifier circuit
Switch mode supply - mains input to PCB
Analogue to Digital converter - including digital control logic, analogue and digital grounding.
Digital to Analogue converter - including digital control logic and analogue buffering
Audio Power Amplifier - including thermal considerations and heat sink selection
Functional fragment of a Microcontroller System - including crystal controlled clock circuit- include LCD display
Functional fragment of a Microprocessor System - including RAM, ROM, digital I/O and bus arrangements
ASIC based circuit assuming die bonding and wire bonding, R/C clock
High speed digital system- high speed processor, memory and digital I/O
Backplane interconnection system, including power, analogue and digital signals
The module is expected to involve 150 hours learning time spread over 12 weeks. All study and assessment is carried out via the internet so there is no requirement to attend in person. The approach is substantially student centred, with tutor support by email and telephone on a one-to-one basis, although peer discussion is encouraged. Students will use industrial standard PCB design software online for exercises and assessments.
