Figure 1. PCB QR code size and placement image for PCB manufacturing review.PCB QR code size and placement determine whether scanners can read a board consistently through assembly, test, shipping, and field service. A code that is too small, too reflective, or too...
Peelable solder mask protects specific board areas during wave soldering, selective soldering, or conformal coating—then removes cleanly when no longer needed. While material selection matters, consistent results depend heavily on how the mask is applied and...
Advanced Product Quality Planning (APQP) for PCB fabrication is a structured way to move a new printed circuit board from design release through production validation and into stable volume builds. Originally developed for automotive supply chains, APQP principles are...
The Production Part Approval Process (PPAP) provides a standardized framework for validating that a printed circuit board supplier can consistently produce parts meeting customer specifications. Originally developed for automotive supply chains, PPAP has become widely...
1. Introduction Knowing how to cut PCB correctly is essential for achieving custom dimensions, separating panelized boards, or removing unwanted sections. The cutting method directly affects the board's electrical performance, mechanical reliability, and edge quality....
1. Introduction: Why is PCB Green? The question of why PCB is green has a straightforward answer rooted in both chemistry and industrial practice. The green color does not originate from the substrate material itself—FR-4, the most common base material, is actually a...
1. Introduction: PCB Shape Definition and Strategic Importance PCB shape refers to the physical outline or geometric form of a printed circuit board. This fundamental design parameter extends beyond aesthetics—it directly influences component placement efficiency,...
Figure 1. Zero PCB BoardIntroduction A zero PCB is a general-purpose prototyping board featuring a grid of pre-drilled holes without any predefined copper traces. Unlike manufactured printed circuit boards with fixed routing, a zero PCB allows engineers and hobbyists...
