Design for Product Build
Selected web site: companies

Whilst we have identified over 70 companies with web sites of interest to students of electronics manufacture, and have identified many of the main suppliers of materials and equipment, such a list inevitably just scratches the surface of what is available. Note that a number of these sites require (free) registration, but also offer a considerable amount of data.

In carrying out the most recent revision (September 2007) we have tried to remove all dead links, and any sites that are lacking in technical interest or are purely commercial. We would welcome your comments and suggestions for improvement – please email Martin Tarr.

Selected web sites: companies
Agilent supply a very wide range of test equipment, including paste inspection, AOI, X-ray and In-Circuit Test, and this link is to their Printed Circuit Board (PCB) Test and Inspection page. You can sign up at for a monthly email newsletter tailored to your areas of interest. This replaces PCB Pulse, a monthly newsletter for electronics manufacturers, to which there are frequent references in the archive.
AIM Solder: a professional solder supplier with a good stock of technical articles.
A useful collection of technical articles under the Alpha Metals banner about Cookson Electronic assembly materials, especially on soldering topics.
Alphasem make die attach systems, which are used to mount semiconductor dice onto lead frames or into hermetic packages. The site is organised by application, so you will be able to see the differences in processes and equipment used for different types of component.
AMI Semiconductor have an interesting range of silicon solutions. The site is a bit ‘thin’ on data, but the company have a positive stance towards lead-free and environmental issues.
Arlon are manufacturers of speciality laminates. Quite a few technical articles, if slightly hidden! Look for ‘Everything you ever wanted to know about laminates . . . but were afraid to ask’, which is a browsable resource with a great deal of information, regrettably last updated in 2000.
Asymtek make automated fluid dispensing equipment for electronics, semiconductor and industrial assembly, and their site has many technical articles and useful links to related sites.
AVX Technical Information Library, for information on ceramic and tantalum capacitors.
BGF Industries make a range of reinforcement materials, as used for printed wiring laminates.
Bob Willis of Electronic Presentation Services has created a site which provides a lot of basic information on assembly issues. Well worth a look!
Cadence have a nicely designed site with extensive technical resources on a very wide range of CAD and related products. Go to the Allegro IC-PKG-PCB co-design or OrCAD PCB design products, and use the Resource Library links to Technical info and Demos and webinars.
The Circuit Technology Centre are a leading edge circuit board repair and rework house with a collection of useful articles and an on-line “Guidebook”, full of detailed procedures for reliable repair and modification of bare and assembled circuit boards. CTC offer Circuit Rework News, a free weekly newsletter, and originated Circuitnet, which is now a separate publication “covering the world of electronics manufacturing”.
A good overview of production equipment available from Contax, plus links to their suppliers.
A site where DEK claim to answer all your printing problems, but some of the data is reserved for customers who have registered. However, DEK have been a great supporter of this module, so much of the most relevant information has already been incorporated in the unit texts and supplementary sheets.
DuPont has a broad portfolio of materials technologies for both semiconductor packaging and circuit applications, and a nicely presented site.
Started by Dionics, a component distributor, this agile business consultants site contains a good summary of the issues involved in the lead-free transition.
Dyconex have a wide range of interconnection technologies that can be used to achieve high density and meet challenging requirements for thermal management. Lots of design guidelines and illustrations, though these tend to be hidden away.
