Flexible Thinking: Musings on High Density Interconnections

10/30/2024 | Joe Fjelstad -- Column: Flexible Thinking
People have been using high density interconnection (HDI) technology since the early 1980s, although it was not called HDI until the late 1990s. In the 1970s, ’80s, and early ’90s, engineers used HDI methods to develop hybrid circuits, which were later referred to as multichip modules (MCMs). These were arguably the first instantiation of heterogeneous interconnection technology, which has been the industry buzzword for almost a decade. These devices are a way of integrating multiple chips—both integrated circuits and discrete devices (resistors, capacitors, and inductors)—into a single package, typically using ceramic substrates with layers of insulation and metallic inks (often gold) and firing them at high temperatures.

Highlights of the ICT 50th Anniversary Symposium

10/24/2024 | Pete Starkey, I-Connect007
Why does it always rain when I attend these events? Temperatures were dropping, daylight was shrinking, and there were seasonal colour changes in wet hedgerows as I travelled to Gloucestershire for the 50th Anniversary Symposium of the Institute of Circuit Technology at Puckrup Hall near Tewkesbury in mid-October. It was a memorable occasion: Nostalgic for my contemporaries who remembered our industry at its most prosperous, technically outstanding in the quality and significance of presentations to an attentive audience of printed circuit professionals, and complemented by the sharing of ideas, information, and trade gossip within a friendly community at the evening gathering.

Designers Notebook: Implementing HDI and UHDI Circuit Board Technology

10/23/2024 | Vern Solberg -- Column: Designer's Notebook
To accommodate new generations of high I/O semiconductor packaging, circuit board technology has undergone significant changes in both the fabrication process method and the criteria for base material selection. The reason behind these changes is the new high-function semiconductor package families that require more terminals than their predecessors and a significantly narrower terminal pitch.
