IMAPS-UK have announced details of a two-day European Conference to be held at the Novotel Hotel, London on 24-25 January 2000. The event is co-sponsored by the IEEE Components, Packaging and Manufacturing Technologies UK and RI Chapter and the IEE.

Under the heading "Microtechnologies for the New Millennium", the conferences will be preceded by a tutorial on "Building MCMs with CSPs and Organic HDI Boards". The two-day conference programme will offer delegates from the electronic industry an opportunity to hear a total of 23 papers presented by experts from leading international companies, research centres and universities.

Day one addresses multichip modules. Entitled EC-MCM-2000, it will be IMAPS' 6th European Conference on the subject.

Day two will focus on microsystems packaging. It will be truly international, with 23 papers being presented over the two days. Expert speakers will represent leading companies, research centres and universities from the UK, Ireland, France, Germany, The Netherlands, Italy, Switzerland, Slovenia and the USA.

As we approach the new Millennium we feel that now is the time to present and discuss the future of the microtechnology industry and its role in the future of electronics.

"CSP + HDI = MCM-L!" (Building MCMS with CSPs and Organic HDI Boards)

Tutorial: 23 January 2000


Charles E. Bauer, PhD, TechLead Corporation

Course description

MCM technology languished throughout most of the 1990s due to high costs resulting from low yields and issues with known good die. During the last five years of the decade new developments in chip scale packages and high density, build up multi-layer printed wiring boards have created new opportunities to design and produce ultra miniaturized modules using conventional surface mount manufacturing capabilities. Focus on the miniaturization of substrate based packages such as ball grid arrays resulted in chip scale packages (CSPs) offering many of the benefits of flip chip along with the handling, testing, manufacturing and reliability capabilities of packaged devices. New developments in the PWB industry sought to reduce the size, weight, thickness and cost of high density interconnect (HDI) substrates. Shrinking geometries of vias and new constructions significantly increased the interconnect density available for MCM-L applications. This tutorial describes the most promising CSP and HDI technologies for portable products, high performance computing and dense multi-chip modules. Coverage includes design rules, materials, processes, constructions and applications. Examples of design rule selection and application case studies demonstrate the application and benefits of these new technologies.
