Design for eXcellence

Resources links

These are mostly PDF files, intended for double-sided printing. Some documents (in particular the EDR web site lists) also have hypertext links that should work within Acrobat Reader.

To help those who have slow internet connections, the size of each file is indicated.

Update policy

This page is intentionally a ‘live’ resource, so we recommend keeping it under review. It was last updated on 25 November 2003 by the addition of some NPL links in the DfE section.

If you come across other interesting sites during your own web research, please email their URLs (or explain the route to the page, if the site doesn't have individual page URLs), together with your comments, to mtarr@btinternet.com. Alternatively, let all your fellow-students know by posting a message on the WebCT Discussions page.

Be aware that both URLs and the content of web pages change so fast that no-one could possibly keep every link totally up-to-date. Please help by advising us of revised URLs and broken links.

Material common to a number of modules

Mentioned in the module introduction, these documents were originally prepared for AMI4812 Materials and Processes for EDR – 2, so have a materials bias.

Selected reading material (130KB)

Selected web sites (155KB)

Glossary of EDR terms (286KB)

DfF, DfA and DfT elements in this module

The following documents are relevant to the module themes but are not all explicitly linked within the teaching material. You will probably want to print them and familiarise yourself with their contents, so that you can judge where in the sequence more detailed study might be helpful. For example, appropriate parts of the Plexus checklist will aid you in tackling Assignments 1 and 2.

Sample Design for Fabrication Capability Statement (73KB)

Circatex Designers' Check List (74KB)

DfA checklist and Good Practice Guide (1.02MB)

Written by Neil Purves of Plexus especially for our course, this is mostly about DfF, with some DfA and DfT content. When they reviewed the draft document, the industry team that helped create the module felt that it gave a very good resume of the issues.

A Guide to Testing and Design for Test (1.12MB)

Made available to us by kind permission of the DTI, this guide was written for the Electronics Design project by Professor Peter Ivey, one of the EDR module development team.

Merix Corporation Manual: Design for Manufacturability of Rigid Multi-Layer Boards (736KB)
This is the latest (1999) version. Keep an eye on http://www.merix.com for the promised update.

You will find many other examples of DfM materials on the internet. These are of varying usefulness and accuracy, and most will be tailored to the requirements of a specific fabricator or assembly house. As when assessing any other web information, try to uncover any ‘hidden agenda’, and be careful to compare the advice given against what you have learnt from this module. After your studies you should be able to understand the reasons behind the inevitable variations in practice.

For a high-reliability manufacturer’s perspective on DfM issues, you might find helpful the articles by Earl Moon (‘Moonman’) at http://www.smtinfo.net/Db/_DFM.html. Earl has also written a book, based on his earlier manual and checklists.

DfE issues in this module

The DfE section of this module includes a number of web-based activities that are explained in the text, so the first three items are just short supplementary documents:

An ISO 14001 overview (415KB)

DfE issues: selected web sites (99KB)

Glossary of some environmental terms (73KB)

Lead-free is a environmental topic that you will come across increasingly during your working life. The move will have enormous effects on the components and materials used. A good web site to keep your eye on is that of NPL's Electronics Interconnection group at http://www.npl.co.uk/ei/.

Alan Brewin from the NPL team has kindly made available to students the April 2002 report by Martin Wickham, Ling Zou and Christopher Hunt: An assessment of the suitability of current PCB laminates to withstand lead-free reflow profiles (399KB).
