PCB Requirements for Factory Automation: PLC and I/O Module Integration In a factory automation environment, printed circuit boards are not just passive components — they are the nervous system of every PLC rack, every I/O module, and every control cabinet on the floor. When a PCB fails in a PLC or I/O module, an entire […]

Industrial Power Supply PCB Design: Creepage, Clearance, and IEC Safety Standards When a PCB carries mains voltage or operates in an industrial environment, the rules that govern copper spacing stop being design preferences and become legal safety requirements. Creepage and clearance distances are not suggestions — they are the physical barriers that stand between your

Understanding PCB Manufacturing Capability Tables: What Those Numbers Really Mean You have found a PCB manufacturer that looks promising. You click through to their capabilities page and see a list of numbers: minimum trace width 2.5 mil, minimum hole size 0.15 mm, aspect ratio 8:1, copper weight 1 oz. It reads like a technical specification

10 DFM Mistakes That Make Your PCB More Expensive (and How to Avoid Them) DFM (Design for Manufacturing) is about making sure your PCB can be fabricated and assembled easily and repeatably with standard processes. When DFM is an afterthought, you pay in extra layers, special processes, rework, and delays—costs that stack up across prototypes and production

Panelization Strategies for Small PCB Orders: V‑Score vs Tab‑Routing vs Breakaway Holes When you only need a few dozen or a few hundred boards, panelization still matters. Proper panels let your manufacturer run your boards through automated SMT lines, reduce handling damage, and lower per‑unit cost even at small volumes. The three most common approaches
