Flying Probe Testing: Revolutionizing PCB Quality Assurance in Modern Electronics Manufacturing
The process for manufacturing printed circuit boards (PCBs) includes a critical testing phase. Each board must undergo testing to ensure manufacturers detect every electrical or circuitry problem before leaving the center. When a PCB passes this testing, it further ensures that it performs reliably. The most common types of testing methods include in-circuit testing (ICT) and flying probe testing (FPT). 6 high-precision probes (needles), 4 on top and 2 on the bottom are programmatically able to contac......

PCB Cleanliness in Professional Manufacturing : Preventing Contamination and Ensuring Long-Term Reliability
In the construction of PCBs, the boards are contaminated with all sorts of dirt at almost every stage. In the soldering process, the flux (either rosin-based or more recent organic forms) may cause residues or ionic salts to remain on the pads and traces and be sticky. Next there is etching, plating and micro-etching; the chemical processes will put metal ions on the copper unless the rinsing is complete. Tiny particles of metal shavings, fiberglass dust, and laminate fragments are also thrown out in ......

Test PCB Board : Complete Testing Methods and Best Practices
As a PCB manufacturer, we always conduct testing with a number of stages, because if you’ve ever designed a PCB and sent a beautifully routed board to JLC, waiting eagerly for delivery, unboxing it like a new iPhone, only to find out later that a single microscopic solder bridge is enough to turn your masterpiece into a glorified coaster. This is exactly why PCB testing exists, and we are focused more extensively on it. PCB testing is like a basic “health checkup” of your electronic product before it ......

Quality Control and Testing in Bare Board Manufacturing
Bare printed circuit boards, or PCBs, are the foundation of almost all electronic devices made today, from computers and cellphones to industrial control systems and aeronautical electronics. Quality control and testing in bare board manufacturing have grown more important since these applications require more dependability. Defects at the PCB level might cause even the most sophisticated circuit designs to fail in the absence of adequate quality assurance. In order to guarantee long-term performance ......

Common Defects in Copper Clad PCBs and How to Avoid Them
Usually all the PCBs, means all of them use CCL(copper clad laminates). It supplies the conductive layer needed to make a circuit work properly. Manufacturers and designers can improve controls and preventative measures by having a better understanding of these flaws and their causes. Copper-clad PCB flaws can impair electrical performance and cause electronic devices to break too soon. The most prevalent copper-clad PCB flaws are examined in this article along with preventative measures. What is a Co......

How to Avoid Copper Peel Off
Hot Air Solder Leveling (HASL) involves coating the surface of the exposed copper with a layer of tin alloy to prevent oxidation and provide a good soldering surface for subsequent assembly. The basic process of HASL is to briefly immerse the PCB board into a high-temperature liquid tin bath. Through the action of flux and high-temperature tin, a copper-tin alloy (IMG) is formed. Then, on guide rails, the board is lifted out while high-pressure gas blows away excess tin from non-copper areas and level......
