How does PCB V-Scoring work? The V-Scoring process involves creating V-shaped grooves on the surface of a PCB panel using a specialized cutting tool. The grooves are typically cut at a 30-degree angle on both sides of the board, creating a 60-degree V-shaped channel. The depth of the groove is carefully controlled to ensure that it penetrates through the majority of the board’s thickness, leaving only a thin layer of material at the bottom of Read more…

What Causes PCB tombstoning? Several factors can contribute to the occurrence of PCB tombstoning: Uneven Heating One of the primary causes of tombstoning is uneven heating during the reflow soldering process. When one end of a chip component heats up faster than the other, it can cause the component to lift off the pad on the cooler side. This uneven heating can be due to: Poor oven temperature profiling Inadequate preheating Improper placement of components Read more…
