Printed Circuit Boards ("PCBs") should be viewed as electronic real estate. Essentially, the reliability of the components that, combined with the PCB, make up your product are only as good as the foundation upon which they are assembled. The relia

You have a board fabrication defect. Search the web for "hole wall pullaway" Performing a microsection is the best way to analyze the defect.

It's not the first thing we think of in looking at your picture. First off, the lack of copper in the region of the red oval makes us think of a plating defect. We don't expect that moisture out-gassing through the barrel wall to show-up on opposite

If a picture is worth a thousand words, the new H revision of IPC-A-600, Acceptability of Printed Boards, is a priceless work of art for fabricators and assemblers, particularly inspectors and product developers. IPC — Association Connecting Electronics Industries® announces the new releases of IPC-A-600H and its companion document the C revision of IPC-6012, Qualification and Performance Specification for Rigid Printed Boards.

More and more people and things are using electronic devices to communicate. Subsequently, many electronic products, in particular mobile base stations and core network nodes, need to handle enormous amounts of data per second. One important link in this communication chain is high speed pressfit connectors that are often used to connect mother boards and back planes in core network nodes. These new high speed pressfit connectors have several hundreds of thin, short and weak pins that are prone to damage. Small variations in via hole dimensions or hole plating thickness affect the connections; if the holes are too small, the pins may be bentor permanently deformed and if the holes are too large they will not form gas tight connections.The goal of this project was to understand how rework of these new high speed pressfit connectors affects connection strengths, hole wall deformations and plating cracks.

The onset of copper barrel cracks is typically induced by the presence of manufacturing defects. In the absence of discernible manufacturing defects, the causes of copper barrel cracks in printed circuit board (PCB) plated through holes is not well understood. Accordingly, there is a need to determine what affects the onset of barrel cracks and then control those causes to mitigate their initiation.The objective of this research is to conduct a design of experiment (DOE) to determine if there is a relationship between PCB fabrication processes and the prevalence of fine barrel cracks. The test vehicle used will be a 16-layer epoxy-based PCB that has two different sized plated through holes as well as buried vias.
