The Ins And Outs Of Receiving And Inspecting Manufactured PCBs When it comes to the process of receiving and inspecting manufactured PCBs, there are two dominating factors: Specify as much as you can on the fab drawings you provide to the PCB manufacture, and thoroughly inspect your first builds to ensure that all of those specifications have been satisfied and that no errors have crept into the fabrication process. This article provides an overview of the receiving and inspection process; the things that Read Article

Controlling Crosstalk In Connector Pinouts This article will describe this type of crosstalk, the types of disruptions it causes, wherein the design cycle it needs to be factored in and how it can be successfully controlled. Read Article

Assembly: The Last Step In The PCB Product Development Process As pointed out in previous articles, design is the first step in the PCB product development process, so the board designer needs to understand how the downstream processes will impact his design processes/selections/decisions, and this understanding needs to encompass both technical and financial considerations. These deliberations are viewed and weighted as trade-offs. What might make sense from a technical standpoint may not always make sense Read Article

Addressing Differential Signaling In Flex Circuits As noted in many previous articles, due to high-speed and high data-rate designs, most modern products utilize differential signaling. If utilizing the right design protocols and design toolsets, handling differential signaling in standard, rigid PCBs is easily doable. But utilizing differential signaling in flex circuits creates another set of issues, questions, and design challenges. This article will address how differential signaling is Read Article

Thought Leader Article, Dave Huntley, PDF Solutions In an ideal world where ideal products are developed, we would never have any issues resulting from any step in the design, fabrication, assembly, test and field operation processes. But in the real product development world that we inhabit, it is a fact that some level of undesired quality and reliability issues will occur. We continually look for novel ways to address these manufacturing issues especially as the components and the PCBs where Read Article
