Layout Review Checklist: Placement, Ground and Decoupling Most layout mistakes are not exotic. They are the same ones that appear in every design review: a part that cannot be replaced, a decoupling capacitor too far from its device, a ground that was never thought about, a connector that collides with…

Avionics PCB: Standards, Materials and Reliability Requirements An avionics board carries the functions that keep an aircraft flying and the people inside it safe, and it does so in an environment that combines vibration, altitude, temperature extremes and a service life measured in decades. The design rules are not exotic,…

EMI Control in Digital Circuits: Layout Techniques Digital circuits are the most common source of electromagnetic interference on a modern board, and they are also the least obvious one. A clock line carries a square wave with fast edges, and a fast edge contains energy at frequencies many times the…

PCB Bed of Nails Fixture: What Buyers and Engineers Should Check Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB bed of nails fixture from the perspective of…

PCB Probe Access on A Dense Board: What Buyers and Engineers Should Check Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB probe access on a dense board…

PCB Electrical Test of A Board: Design, Process, and Quality Notes Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB electrical test of a board gives…

PCB Design for Boundary Scan: Design, Process, and Quality Notes Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This…

PCB in Circuit Test Program: What Buyers and Engineers Should Check Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years.…

PCB Coupon on the Panel: A Test Piece That Travels Along Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years.…

How to Choose PCB Design Software for Your Team Every PCB design software package on the market can draw a board, so the choice cannot be made on feature lists alone. What separates tools in daily use is how they handle the tedious parts: keeping the footprint library consistent, catching…
