DO-254 Avionics PCB Design — Design Assurance, DAL Levels & DO-160 Qualification

DO-254 Avionics PCB Design — Design Assurance, DAL Levels & DO-160 Qualification

DO-254 governs design assurance for airborne electronic hardware, and the evidence is what makes a board certifiable. Learn the DAL levels A–E, what a DAL A boa

112G / 224G SerDes PCB Design — Loss Budget, Stackup & Laminate Choice for 800G Ethernet

112G / 224G SerDes PCB Design — Loss Budget, Stackup & Laminate Choice for 800G Ethernet

Designing a board for 112G or 224G SerDes is a channel problem, not a routing problem. Learn the insertion-loss budget, low-loss laminate selection, backdrill a

How to Place a PCB Purchase Order — PO Checklist & Order Confirmation

How to Place a PCB Purchase Order — PO Checklist & Order Confirmation

A PCB purchase order is the bridge between a quote and a build — and it is where most ambiguity creeps in. Learn what to put in a PO, how order confirmation pro

How to Prepare a PCB Assembly BOM — 7 Mistakes That Cost You Time

How to Prepare a PCB Assembly BOM — 7 Mistakes That Cost You Time

A BOM for PCB assembly is not a parts list — it is a manufacturing contract. Learn the required fields, the consignment vs turnkey difference and the 7 mistakes

PCB Engineering Change Order (ECO) — Revision Control That Protects Your Schedule

PCB Engineering Change Order (ECO) — Revision Control That Protects Your Schedule

An ECO to a PCB has ripple effects far beyond the board: re-quotes, stale parts, old stencils and a scrap pile. Here is how a disciplined revision-control and e

Automotive Radar PCB Design — 77-81 GHz ADAS Sensor, RF Laminate & MMIC Integration

Automotive Radar PCB Design — 77-81 GHz ADAS Sensor, RF Laminate & MMIC Integration

Designing a 77-81 GHz automotive radar PCB is a high-frequency discipline: low-loss RF laminate, tightly toleranced etching, MMIC and patch-antenna integration,
