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—Outer Layer Imaging

09/26/2024 | Matt Stevenson -- Column: Connect the Dots
Welcome to the next step in the manufacturing process—the one that gets the chemical engineer in all of us excited. I am referring to outer layer imaging, or how we convert digital designs to physical products. On a recent episode of I-Connect007’s On the Line with… podcast, we explained how the outer layer imaging process maps the design’s unique features onto the board.

Trouble in Your Tank: Things You Can Do for Better Wet Process Control

09/11/2024 | Michael Carano -- Column: Trouble in Your Tank
For 40 years, I have been involved in the printed circuit board, circuit board assembly, and semiconductor technology segments, preaching about minimizing defects and improving yields. This is especially true as technology becomes increasingly complex, and additional focus must be placed on yield improvements. Process management and wet process control must be front and center, so it’s quite interesting and timely to talk about wet process control and management for this month’s issue. This theme fits quite well with today's global events. For this industry, the technical curve has steepened dramatically in the past few years.

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.
