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
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.
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
Differential Signaling In High Speed Data Link Flexible 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
LearnEMC CEO Todd Hubing on Engineering Consulting Services
Kella Knack interviews Dr. Todd Hubing a top EMC expert. They discussed topics about the design challenges in Automotive Industry and tackled EMC concerns at the board level.
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
Comparing PDN Inductance to the Inductance of a Capacitor
Here's how PDN inductance affects power integrity and signal integrity in your high speed PCB. Read this blog to learn more.
What Is Thieving In PCBs And Why Is It Done?
In this Article, Expert Kella Knack describes thieving, to what sections of the board it is applied; at what point in the fabrication is it done, how it relates to plating operations; who is responsible for adding thieving to the outer layer artwork and its shortcomings and benefits.
PDS Impedance: The Traditional Approach To PDS Design vs. Energy Flow
Take a look at traditional PDS impedance versus the “energy flow” view of PDS design. We’ll debunk misleading information that could cause your designs to fail.
