A Basic Guide to PCB Design and Manufacturing

2026-03-26

Design professionals often talk about design-for-manufacturing guidelines, but what exactly are these guidelines and how are they implemented in your PCB design software? In PCB development, design for manufacturing has a very simple meaning: you should only implement a design choice if it ensures maximum manufacturable yield.

How to Select PCB Pads

2026-03-26

In PCB manufacturing, solder bridging (unintended solder connection between adjacent pads) is a common issue, mainly caused by improper pad design. If left unaddressed, it can lead to short circuits and functional failure. This article introduces three pad types to prevent solder bridging.

Is It Still Necessary to Use Via‑in‑Pad After Adding Blind/Buried Vias on a PCB?

2026-03-25

In PCB design, via types include blind vias, buried vias, and via‑in‑pad vias, each with different applications and advantages. Blind and buried vias are mainly used for electrical connections between layers of multilayer PCBs, while via‑in‑pad vias are used for component mounting and soldering. If blind and buried vias have been added to a PCB, is it still necessary to use via‑in‑pad vias?
