LED lighting has transformed from a niche technology into a $70+ billion global industry, with circuit boards serving as the critical backbone of every luminaire. PCBA manufacturing for…
Your product’s success hinges on a decision most companies underestimate: selecting the right PCBA manufacturer. A single production defect can trigger costly recalls, damage your brand reputation, or…
Since the European Union formally legislated “lead-free” in December 2003, the global electronics industry felt a strong impact. By July 2006, the EU directives on Waste Electrical and…
1. Recent PCB Leakage Issue Overview We recently faced a PCB leakage issue. The product is low-power. The whole device normally draws microamp-level (µA) current. After normal-temperature aging…
1. Definition and When to Add Layers For high-speed multilayer boards, a basic two-layer design often cannot meet the needs for signal quality and routing density. In that…
This note explains why PCB panels can change size during processing and how to control this. From the first inner-layer pattern transfer on the PCB base material, through…
Open and short circuits in PCB traces are problems that almost every PCB manufacturer meets almost every day. These problems keep production and quality staff busy. They cause…
In PCB design we must pay attention to vibration. We must plan for vibration fatigue. If we do not, a PCB will not last long. Many boards sit…
1. What is copper foil? Copper foil is a thin, continuous metal sheet. It is an electro-deposited, negative-type material. The foil is plated onto the base of the…
Material coefficient of thermal expansion (CTE) is one physical property of a material. When temperature changes, the part will change shape and will have stress. We cannot stop…
Cleanliness is not only for devices used in medicine. In fact, avoiding things like ionic contamination during the manufacture and assembly of circuit boards for medical electronic devices…
A trace impedance target does not automatically define the impedance of a via transition. A via is a three-dimensional discontinuity involving a plated barrel, pads, antipads, reference planes,…
