Trouble in Your Tank: Interconnect Defect—The Three Degrees of Separation

10/01/2024 | Michael Carano -- Column: Trouble in Your Tank
It has been well documented that, with a very expensive and complex printed circuit board, thermal and mechanical excursions often find weaknesses. A lack of robustness and poor process control often leads to the exploitation of those weaknesses. An interconnect defect (ICD) often goes undetected until the printed circuit board reaches the final assembly stage or undergoes multiple thermal cycles, including interconnect stress tests or thermal shock. It is impossible to rework the ICD defect. But unlike voids, if detected in time, the panels can be reprocessed.

Connect the Dots: Designing for Reality—Electroless Copper

08/28/2024 | Matt Stevenson -- Column: Connect the Dots
Roll up your sleeves because it's time to get messy. In a recent episode of I-Connect007’s On the Line with… podcast, we discussed electroless copper deposition. This process deposits a copper layer into the through-holes and vias of what will eventually be a PCB. Electroless copper deposition feels like a black box to many people. It sort of looks like a black box, too. The boards go in one side, come out the other, and emerge differently. So, let's crack open that black box and look inside.

Trouble in Your Tank: Processes to Support IC Substrates and Advanced Packaging, Part 5

08/06/2024 | Michael Carano -- Column: Trouble in Your Tank
Direct metallization systems based on conductive graphite or carbon dispersion are quickly gaining acceptance throughout the world. Indeed, the environmental and productivity gains one can achieve with this process are outstanding. In today’s highly competitive and litigious environment, direct metallization reduces costs associated with compliance, waste treatment, and legal issues related to chemical exposure. What makes these processes leaders in the direct metallization space? This is detailed below.
