Expert in Soldering - Bob Willis

Bob Willis

Bob Willis has been providing training and consultancy services in the electronics industry for the last 15 years. Through experience in conventional, surface mount, ball grid array and printed board manufacture Bob is able to bring both practical and theoretical experience to customers’ lead-free training and consultancy projects. With one of the widest ranges of training products in the industry, Bob is also able to provide both lead-free in-house training and distance learning products as well as inspection and quality control materials. Bob is an active member of the SMART Group, Europe’s largest surface mount and related technologies association as well as many other trade groups like IPC, SMTA and ICT. Although much of the work in Europe is training and providing process support he has also been involved in running training events and consultancy in the USA and the Far East.


Assembly and soldering problems often occur in our industry and sometimes support to quickly eliminate the true cause of production failures can be beneficial. Lead-free can be achieved with a technical support program or an on site examination of products or processes. Selecting lead-free materials, equipment, new processes or reviewing designs for manufacture can often require additional technical support for your company. Selecting printed board suppliers or contract assembly services is another service we provide for our customers. When and if field failures occur with lead-free it is beneficial to have an independent view, this can often pinpoint the real cause of the problem. Independent views can avoid protracted discussions, which may lead to unnecessary cost implications.

Our lead-free in-house training workshops can be run as theoretical sessions or complete hands-on events based on our standard training modules. Alternatively any of the workshops can be modified to suit individual company requirements. A full listing of the workshop contents can be provided by email or obtained direct from our website.
