IPC: Changes in Store for PCB Suppliers

BANNOCKBURN, Ill. — PCB Technology Trends 2011, a new study published by IPC — Association Connecting Electronics Industries — shows how the demands of miniaturization and high-speed technology are driving changes in printed circuit board (PCB) processes and materials. The 53-page report presents the technology demands of today and foretells the changes expected by 2014 that will affect PCB fabricators as well as materials and equipment suppliers.

IPC’s PCB technology trends study was conducted in late 2011 in English and Chinese. Forty-one PCB manufacturing companies participated, including many of the leading companies in Asia, Europe and North America. They represent 16.5 percent of the world PCB market. The IPC study sample is representative of the global industry in terms of company size and product mix.

Between 2011 and 2014, high-density interconnect (HDI) board production is expected to grow 26 percent for the companies that participated in IPC’s PCB Technology Trends study. They also anticipate greater use of stacked and staggered microvias, leading to any-layer microvias and “via anywhere” capability. While miniaturization and the demands of high-speed technology are driving these trends, companies cite solder mask registration and assembly as the two most common factors limiting the miniaturization of circuitry dimensions.

Most of the companies are evaluating new surface finishes, especially electroless nickel, immersion palladium and immersion gold (ENIPIG). The report also confirms that the high price of gold is having an impact on changes in PCB processing, with nearly one-quarter of the participants trying alternative metals. Seventeen percent of respondents are trying to use reduced thicknesses of gold, including some who claim that the price of gold is having no impact on their material selection.

Of the two primary substrate materials used today, multi-function epoxy resin is expected to grow to be used in more than half of panel area produced by 2014, while the use of glass fabric is expected to decline. Companies’ data on laminates used today along with forecasts for 2014 show laminates moving toward higher-temperatures thermal properties. They also predict the use of more low-loss materials. It is expected that by 2014 nearly half of the panel area produced will be halogen free and nearly three-quarters will be lead free.

PCB Technology Trends 2011 is available free to companies that participated in the survey. Other companies may purchase the report by visiting IPC.

    Compartively there is not many break through technologies in pcb manufacturing. Most of the advancements are related to the process to use no lead and to produce halogen free pcb's. But on the other side semiconductor technologies going through a revolution with technologies like 3d manufacturing and TSV.

    “Most of the companies are evaluating new surface finishes, especially electroless nickel, immersion palladium and immersion gold (ENIPIG).”

    Where can we find more information about ENIPIG because it the first time that I read about these new technologies.

    ENIPIG is new to me as well. Here is a bit of info on it: Does anyone here have any access to papers written about the comparison of PCB finishes? I would be interested in having info like that all in one paper.

    Is ENIPIG better to ENIG or does it olny have advantage of using less gold?
