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.

The Chemical Connection: Troubleshooting PCB Process Problems

10/29/2024 | Don Ball -- Column: The Chemical Connection
As a supplier of PCB wet processing equipment, we inevitably find ourselves involved in helping customers solve sudden process problems that may or may not be caused by equipment malfunctions. For the most part, equipment problems are relatively easy to identify and repair: sensors for chemistry and equipment control, clogged nozzles and filters, leaks in the plumbing, etc. But what happens when the equipment checks out and the problem is still there?
